|
As noted in the
prior section, e-banking has unique characteristics that may increase
an institution’s overall risk profile and the level of risks associated
with traditional financial services, particularly strategic, operational,
legal, and reputation risks. These unique e-banking characteristics include:
| |
Speed
of technological change, |
| |
Changing
customer expectations, |
| |
Increased
visibility of publicly accessible networks (e.g., the Internet), |
| |
Less
face-to-face interaction with financial institution customers, |
| |
Need
to integrate e-banking with the institution’s legacy computer
systems, |
| |
Dependence
on third parties for necessary technical expertise, and |
| |
Proliferation
of threats and vulnerabilities in publicly accessible networks. |
Management
should review each of the processes discussed in this section to adapt
and expand the institution’s risk management practices as necessary
to address the risks posed by e-banking activities. While these processes
mirror those discussed in other booklets of the IT Handbook,
they are discussed below from an e-banking perspective. For more detailed
information on each of these processes, the reader should review the corresponding
booklet of the IT Handbook.
BOARD AND MANAGEMENT OVERSIGHT
Action
Summary
E-BANKING
STRATEGY
Financial institution management should choose the level of e-banking
services provided to various customer segments based on customer needs
and the institution’s risk assessment considerations. Institutions
should reach this decision through a board-approved, e-banking strategy
that considers factors such as customer demand, competition, expertise,
implementation expense, maintenance costs, and capital support. Some institutions
may choose not to provide e-banking services or to limit e-banking services
to an informational website. Financial institutions should periodically
re-evaluate this decision to ensure it remains appropriate for the institution’s
overall business strategy. Institutions may define success in many ways
including growth in market share, expanding customer relationships, expense
reduction, or new revenue generation. If the financial institution determines
that a transactional website is appropriate, the next decision is the
range of products and services to make available electronically to its
customers.
To deliver those products and services, the financial institution may
have more than one website or multiple pages within a website for various
business lines.
COST-BENEFIT ANALYSIS AND RISK ASSESSMENT
Financial institutions should base any decision to implement e-banking
products and services on a thorough analysis of the costs and benefits
associated with such action. Some of the reasons institutions offer e-banking
services include:
| |
Lower
operating costs, |
| |
Greater
geographic diversification, |
| |
Improved
or sustained competitive position, |
| |
Increased
customer demand for services, and |
| |
New
revenue opportunities. |
The
individuals conducting the cost-benefit analysis should clearly understand
the risks associated with e-banking so that cost considerations fully
incorporate appropriate risk mitigation controls. Without such expertise,
the cost-benefit analysis will most likely underestimate the time and
resources needed to properly oversee e-banking activities, particularly
the level of technical expertise needed to provide competent oversight
of in-house or outsourced activities. In addition to the obvious costs
for personnel, hardware, software, and communications, the analysis should
also consider:
| |
Changes
to the institution’s policies, procedures, and practices; |
| |
The
impact on processing controls for legacy systems; |
| |
The
appropriate networking architecture, security expertise, and software
tools to maintain system availability and to protect and respond to
unauthorized access attempts; |
| |
The
skilled staff necessary to support and market e-banking services during
expanded hours and over a wider geographic area, including possible
expanded market and cross-border activity; |
| |
The
additional expertise and MIS needed to oversee e-banking vendors or
technology service providers; |
| |
The
higher level of legal, compliance, and audit expertise needed to support
technology-dependent services; |
| |
Expanded
MIS to monitor e-banking security, usage, and profitability and to
measure the success of the institution’s e-banking strategy; |
| |
Cost
of insurance coverage for e-banking activities; |
| |
Potential
revenues under different pricing scenarios; |
| |
Potential
losses due to fraud; and |
| |
Opportunity
costs associated with allocating capital to e-banking efforts. |
MONITORING AND ACCOUNTABILITY
Once an institution implements its e-banking strategy, the board and management
should periodically evaluate the strategy’s effectiveness. A key
aspect of such an evaluation is the comparison of actual e-banking acceptance
and performance to the institution’s goals and expectations. Some
items that the institution might use to monitor the success and cost effectiveness
of its e-banking strategy include:
| |
Revenue
generated, |
| |
Website
availability percentages, |
| |
Customer
service volumes, |
| |
Number
of customers actively using e-banking services, |
| |
Percentage
of accounts signed up for e-banking services, and |
| |
The
number and cost per item of bill payments generated. |
Without
clearly defined and measurable goals, management will be unable to determine
if e-banking services are meeting the customers’ needs as well as
the institution’s growth and profitability expectations.
In
evaluating the effectiveness of the institution’s e-banking strategy,
the board should also consider whether appropriate policies and procedures
are in effect and whether risks are properly controlled. Unless the initial
strategy establishes clear accountability for the development of policies
and controls, the board will be unable to determine where and why breakdowns
in the risk control process occurred.
AUDIT
An important component of monitoring is an appropriate independent audit
function. Financial institutions offering e-banking products and services
should expand their audit coverage commensurate with the increased complexity
and risks inherent in e-banking activities. Financial institutions offering
e-banking services should ensure the audit program expands to include:
| |
Scope
and coverage, including the entire e-banking process as applicable
(i.e., network configuration and security, interfaces to legacy systems,
regulatory compliance, internal controls, and support activities performed
by third-party providers); |
| |
Personnel
with sufficient technical expertise to evaluate security threats and
controls in an open network (i.e., the Internet); and |
| |
Independent
individuals or companies conducting the audits without conflicting
e-banking or network security roles. |
MANAGING OUTSOURCING RELATIONSHIPS
Action
Summary 
DUE
DILIGENCE FOR OUTSOURCING SOLUTIONS
A key consideration in preparing an e-banking cost-benefit analysis is
whether the financial institution supports e-banking services in-house
or outsources support to one or more third parties (i.e., a technology
service provider or TSP). Transactional e-banking is typically a front-end
system that relies on a programming link called an interface to transfer
information and transactions between the e-banking system and the institution’s
core processing applications (e.g., loans, deposits, asset management).
Such interfaces can be between in-house systems, outsourced systems, or
a combination of both. This flexibility allows institutions to select
those products and services that best meet their e-banking needs, but
it can also complicate the vendor oversight process when multiple vendors
are involved. Choosing to use the services of one or more TSPs can help
financial institutions manage costs, obtain necessary expertise, expand
customer product offerings, and improve service quality. However, this
choice does not absolve financial institutions from understanding and
managing the risks associated with TSP services. In fact, service providers
may introduce additional risks and interdependencies that financial institutions
must understand and manage.
Table
2 below summarizes some of the advantages and disadvantages of supporting
technology-based products and services in-house versus contracting for
support with a TSP. Regardless of whether an institution’s e-banking
services are outsourced or processed in-house, the institution should
periodically review whether this arrangement continues to meet current
and anticipated future needs.

CONTRACTS
FOR THIRD-PARTY SERVICES
As with all outsourced financial services, institutions must have a formal
contract with the TSP that clearly addresses the duties and responsibilities
of the parties involved. In the past, some institutions have had informal
security expectations for software vendors or Internet access providers
that had never been committed to writing. This lack of clear responsibilities
and consensus has lead to breakdowns in internal controls and allowed
security incidents to occur. The IT Handbook’s “Outsourcing
Technology Services Booklet” lists detailed contract recommendations
for TSPs. Institutions should tailor these recommendations to e-banking
services as necessary. Specific examples of e-banking contract issues
include:
| |
Restrictions
on use of nonpublic customer information collected or stored by the
TSP; |
| |
Requirements
for appropriate controls to protect the security of customer information
held by the TSP; |
| |
Service-level
standards such as website “up-time,” hyperlink performance,
customer service response times, etc.; |
| |
Incident
response plans, including notification responsibilities, to respond
to website outage, defacement, unauthorized access, or malicious code; |
| |
Business
continuity plans for e-banking services including alternate processing
lines, backup servers, emergency operating procedures, etc.; |
| |
Performance
of, and access to, vulnerability assessments, penetration tests, and
financial and operations audits; |
| |
Limitations
on subcontracting of services, either domestically or internationally;
|
| |
Choice
of law and jurisdiction for dispute resolution and access to information
by the financial institution and its regulators; and |
| |
For
foreign-based vendors or service providers (i.e., country of residence
is different from that of the institution), in addition to the above
items, contract options triggered by increased risks due to adverse
economic or political developments in the vendor’s or service
provider’s home country. |
OVERSIGHT AND MONITORING OF THIRD PARTIES
Financial institutions that outsource e-banking technical support must
provide sufficient oversight of service providers’ activities to
identify and control the resulting risks. The key to good oversight typically
lies in effective MIS. However, for MIS to be effective the financial
institution must first establish clear performance expectations. Wherever
possible, these expectations should be clearly documented in the service
contract or an addendum to the contract. Effective and timely MIS can
alert the serviced institution to developing service, financial or security
problems at the vendor — problems that might require execution of
contingency plans supporting a change in vendor or in the existing service
relationship.
The
type and frequency of monitoring reports needed varies, depending on the
complexity of the services provided and the division of responsibilities
between the institution and its service provider(s). Service providers
can build MIS capabilities into the administrative modules of their application,
provide on-line reports, or they can provide periodic written reports.
Some examples of items that might be tracked by e-banking monitoring reports
are listed below:
E-banking
service availability. Reports might include statistics regarding
the frequency and duration of service disruptions, including the reasons
for any service disruptions (maintenance, equipment/network problems,
security incidents, etc.); “up time” and “down time”
percentages for website and e-banking services; and volume and type of
website access problems reported by e-banking customers.
Activity
levels and service volumes. Reports might include number of accounts
serviced, number and percentage of new, active, or inactive accounts;
breakdown of intrabank transfers by number, dollar size, and account type;
bill payment activity by number, average dollar, and recurring versus
one-time payments; volume of associated ACH returns and rejects, fee breakdown
by source and type; and activity on informational website usage by webpages
viewed.
Performance
efficiency. Reports might include average response times by time
of day (including complaints about slow response); bill payment activity
by check versus ACH; server capacity utilization; customer service contacts
by type of inquiry and average time to resolution; and losses from errors,
fraud, or repudiated items.
Security incidents. Reports might include volume of rejected log-on attempts,
password resets, attempted and successful penetration attempts, number
and type of trapped viruses or other malicious code, and any physical
security breaches.
Vendor
stability. Reports might include quarterly or annual financial reports,
number of new or departing customers, changes in systems or equipment,
and employee turnover statistics, including any changes in management
positions.
Quality
Assurance. Reports on performance, audit results, penetration tests,
and vulnerability assessments, including servicer actions to address any
identified deficiencies.
INFORMATION SECURITY PROGRAM
Action
Summary 
Information
security is essential to a financial institution’s ability to deliver
e-banking services, protect the confidentiality and integrity of customer
information, and ensure that accountability exists for changes to the
information and the processing and communications systems. Depending on
the extent of in-house technology, a financial institution’s e-banking
systems can make information security complex with numerous networking
and control issues. The IT Handbook’s “Information
Security Booklet” addresses security in much greater detail. Refer
to that booklet for additional information on security and to supplement
the examination coverage in this booklet.
SECURITY
GUIDELINES
Financial institutions must comply with the “Guidelines Establishing
Standards for Safeguarding Customer Information” (guidelines) as
issued pursuant to the Gramm–Leach–Bliley Act of 1999 (GLBA).
When
financial institutions introduce e-banking or related support services,
management must re-assess the impact to customer information under the
GLBA. The guidelines require financial institutions to:
| |
Ensure
the security and confidentiality of customer information; |
| |
Protect
against any anticipated threats or hazards to the security or integrity
of such information; and |
| |
Protect
against unauthorized access to or use of such information that could
result in substantial harm or inconvenience to any customer. |
The guidelines outline specific measures institutions should consider
in implementing a security program. These measures include:
| |
Identifying
and assessing the risks that may threaten consumer information; |
| |
Developing
a written plan containing policies and procedures to manage and control
these risks; |
| |
Implementing
and testing the plan; and |
| |
Adjusting
the plan on a continuing basis to account for changes in technology,
the sensitivity of customer information, and internal or external
threats to information security. |
The guidelines also outline the responsibilities of management to oversee
the protection of customer information including the security of customer
information maintained or processed by service providers. Oversight of
third-party service providers and vendors is discussed in this booklet
under the headings “Board and Management Oversight” and “Managing
Outsourcing Relationships.” Additional information on the guidelines
can be found in the IT Handbook’s “Management Booklet.”
The IT Handbook’s “Information Security Booklet”
presents additional information on the risk assessment process and information
processing controls.
The
guidelines required by the GLBA apply to customer information stored in
electronic form as well as paper-based records. Examination procedures
specifically addressing compliance with the GLBA guidelines can be accessed
through the agency websites listed in the reference section of this booklet.
Although the guidelines supporting GLBA define customer as “a consumer
who has a customer relationship with the institution,” management
should consider expanding the written information security program to
cover the institution’s own confidential records as well as confidential
information about its commercial customers.
INFORMATION
SECURITY CONTROLS
Security threats can affect a financial institution through numerous vulnerabilities.
No single control or security device can adequately protect a system connected
to a public network. Effective information security comes only from establishing
layers of various control, monitoring, and testing methods. While the
details of any control and the effectiveness of risk mitigation depend
on many factors, in general, each financial institution with external
connectivity should ensure the following controls exist internally or
at their TSP.
| |
Ongoing
knowledge of attack sources, scenarios, and techniques. Financial
institutions should maintain an ongoing awareness of attack threats
through membership in information-sharing entities such as the Financial
Services - Information Sharing and Analysis Center (FS-ISAC), Infragard,
the CERT Coordination Center, private mailing lists, and other security
information sources. All defensive measures are based on knowledge
of the attacker’s capabilities and goals, as well as the probability
of attack. |
| |
Up-to-date
equipment inventories, and network maps. Financial institutions
should have inventories of machines and software sufficient to support
timely security updating and audits of authorized equipment and software.
In addition, institutions should understand and document the connectivity
between various network components including remote users, internal
databases, and gateway servers to third parties. Inventories of hardware
and the software on each system can accelerate the institution’s
response to newly discovered vulnerabilities and support the proactive
identification of unauthorized devices or software. |
| |
Rapid
response capability to react to newly discovered vulnerabilities.
Financial institutions should have a reliable process to become aware
of new vulnerabilities and to react as necessary to mitigate the risks
posed by newly discovered vulnerabilities. Software is seldom flawless.
Some of those flaws may represent security vulnerabilities, and the
financial institution may need to correct the software code using
temporary fixes, sometimes called a “patch.” In some cases,
management may mitigate the risk by reconfiguring other computing
devices. Frequently, the financial institution must respond rapidly,
because a widely known vulnerability is subject to an increasing number
of attacks. |
| |
Network
access controls over external connections. Financial institutions
should carefully control external access through all channels including
remote dial-up, virtual private network connections, gateway servers,
or wireless access points. Typically, firewalls are used to enforce
an institution’s policy over traffic entering the institution’s
network. Firewalls are also used to create a logical buffer, called
a “demilitarized zone,” or DMZ, where servers are placed
that receive external traffic. The DMZ is situated between the outside
and the internal network and prevents direct access between the two.
Financial institutions should use firewalls to enforce policies regarding
acceptable traffic and to screen the internal network from directly
receiving external traffic. |
| |
System
hardening. Financial institutions should “harden”
their systems prior to placing them in a production environment. Computer
equipment and software are frequently shipped from the manufacturer
with default configurations and passwords that are not sufficiently
secure for a financial institution environment. System “hardening”
is the process of removing or disabling unnecessary or insecure services
and files. A number of organizations have current efforts under way
to develop security benchmarks for various vendor systems. Financial
institutions should assess their systems against these standards when
available. |
| |
Controls
to prevent malicious code. Financial institutions should reduce
the risks posed by malicious code by, among other things, educating
employees in safe computing practices, installing anti-virus software
on servers and desktops, maintaining up-to-date virus definition files,
and configuring their systems to protect against the automatic execution
of malicious code. Malicious code can deny or degrade the availability
of computing services; steal, alter, or insert information; and destroy
any potential evidence for criminal prosecution. Various types of
malicious code exist including viruses, worms, and scripts using active
content. |
| |
Rapid intrusion detection and response procedures. Financial
institutions should have mechanisms in place to reduce the risk of
undetected system intrusions. Computing systems are never perfectly
secure. When a security failure occurs and an attacker is “in”
the institution’s system, only rapid detection and reaction
can minimize any damage that might occur. Techniques used to identify
intrusions include intrusion detection systems (IDS) for the network
and individual servers (i.e., host computer), automated log correlation
and analysis, and the identification and analysis of operational anomalies.
|
| |
Physical
security of computing devices. Financial institutions should
mitigate the risk posed by unauthorized physical access to computer
equipment through such techniques as placing servers and network devices
in areas that are available only to specifically authorized personnel
and restricting administrative access to machines in those limited
access areas. An attacker’s physical access to computers and
network devices can compromise all other security controls. Computers
used by vendors and employees for remote access to the institution’s
systems are also subject to compromise. Financial institutions should
ensure these computers meet security and configuration requirements
regardless of the controls governing remote access. |
| |
User
enrollment, change, and termination procedures. Financial institutions
should have a strong policy and well-administered procedures to positively
identify authorized users when given initial system access (enrollment)
and, thereafter, to limit the extent of their access to that required
for business purposes, to promptly increase or decrease the degree
of access to mirror changing job responsibilities, and to terminate
access in a timely manner when access is no longer needed. |
| |
Authorized
use policy. Each financial institution should have a policy that
addresses the systems various users can access, the activities they
are authorized to perform, prohibitions against malicious activities
and unsafe computing practices, and consequences for noncompliance.
All internal system users and contractors should be trained in, and
acknowledge that they will abide by, rules that govern their use of
the institution’s system. |
| |
Training.
Financial institutions should have processes to identify, monitor,
and address training needs. Each financial institution should train
their personnel in the technologies they use and the institution’s
rules governing the use of that technology. Technical training is
particularly important for those who oversee the key technology controls
such as firewalls, intrusion detection, and device configuration.
Security awareness training is important for all users, including
the institution’s e-banking customers. |
| |
Independent
testing. Financial institutions should have a testing plan that
identifies control objectives; schedules tests of the controls used
to meet those objectives; ensures prompt corrective action where deficiencies
are identified; and provides independent assurance for compliance
with security policies. Security tests are necessary to identify control
deficiencies. An effective testing plan identifies the key controls,
then tests those controls at a frequency based on the risk that the
control is not functioning. Security testing should include independent
tests conducted by personnel without direct responsibility for security
administration. Adverse test results indicate a control is not functioning
and cannot be relied upon. Follow-up can include correction of the
specific control, as well as a search for, and correction of, a root
cause. Types of tests include audits, security assessments, vulnerability
scans, and penetration tests. |
AUTHENTICATING E-BANKING CUSTOMERS
E-banking introduces the customer as a direct user of the institution’s
technology. Customers have to log on and use the institution’s systems.
Accordingly, the financial institution must control their access and educate
them in their security responsibilities. While authentication controls
play a significant role in the internal security of an organization, this
section of the booklet discusses authentication only as it relates to
the e-banking customer.
Authenticating
New Customers
Verifying a customer’s identity, especially that of a new customer,
is an integral part of all financial services. Consistent with the USA
PATRIOT Act, federal regulations require that by October 1, 2003, each
financial institution must develop and implement a customer identification
program (CIP) that is appropriate given the institution’s size,
location and type of business.
The
CIP must be written, incorporated into the institution’s Bank Secrecy
Act/Anti-Money Laundering program, and approved by the institution’s
board of directors. The CIP must include risk-based procedures to verify
the identity of customers (generally persons opening new accounts). Procedures
in the program should describe how the bank will verify the identity of
the customer using documents, nondocumentary methods, or a combination
of both. The procedures should reflect the institution’s account
opening processes – whether face-to-face or remotely as part of
the institution’s e-banking services.
As
part of its nondocumentary verification methods, a financial institutions
may rely on third parties to verify the identity of an applicant or assist
in the verification. The financial institution is responsible for ensuring
that the third party uses the appropriate level of verification procedures
to confirm the customer’s identity. New account applications submitted
on-line increase the difficulty of verifying the application information.
Many institutions choose to require the customer to come into an office
or branch to complete the account opening process. Institutions conducting
the entire account opening process through the mail or on-line should
consider using third-party databases to provide:
| |
Positive
verification to ensure that material information provided by
an applicant matches information available from third-party sources,
|
| |
Logical
verification to ensure that information provided is logically
consistent, and |
| |
Negative
verification to ensure that information provided has not previously
been associated with fraudulent activity (e.g., an address previously
associated with a fraudulent application ). |
Authenticating Existing Customers
In addition to the initial verification of customer identities, the financial
institution must also authenticate its customers’ identities each
time they attempt to access their confidential on-line information. The
authentication method a financial institution chooses to use in a specific
e-banking application should be appropriate and “commercially reasonable”
in light of the risks in that application. Whether a method is a commercially
reasonable system depends on an evaluation of the circumstances. Financial
institutions should weigh the cost of the authentication method, including
technology and procedures, against the level of protection it affords
and the value or sensitivity of the transaction or data to both the institution
and the customer. What constitutes a commercially reasonable system may
change over time as technology and standards evolve.
Authentication methods involve confirming one or more of three factors:
| |
Something
only the user should know, such as a password or PIN; |
| |
Something
the user possesses, such as an ATM card, smart card, or token; or |
| |
Something
the user is, such as a biometric characteristic like a fingerprint
or iris pattern. |
Authentication methods that depend on more than one factor are typically
more difficult to compromise than single-factor systems therefore suggesting
a higher reliability of authentication. For example, the use of a customer
ID and password is considered single-factor authentication since both
items are something the user knows. A common example of two-factor authentication
is found in most ATM transactions where the customer is required to provide
something the user possesses (i.e., the card) and something the user knows
(i.e., the PIN). Single factor authentication alone may not be adequate
for sensitive communications, high dollar value transactions, or privileged
user access (i.e., network administrators). Multi-factor techniques may
be necessary in those cases. Institutions should recognize that a single
factor system may be “tiered” (e.g., require multiple passwords)
to enhance security without the implementation of a true two-factor system.
Password
Administration
Despite the concerns regarding single-factor authentication, many e-banking
services still rely on a customer ID and password to authenticate an existing
customer. Some security professionals criticize passwords for a number
of reasons including the need for passwords whose strength places the
password beyond the user’s ability to comply with other password
policies such as not writing the password down. Password-cracking software
and log-on scripts can frequently guess passwords regardless of the use
of encryption. Popular acceptance of this form of authentication rests
on its ease of use and its adaptability within existing infrastructures.
Financial
institutions that allow customers to use passwords with short character
length, readily identifiable words or dates, or widely used customer information
(e.g., Social Security numbers) may be exposed to excessive risks in light
of the security threats from hackers and fraudulent insider abuse. Stronger
security in password structure and implementation can help mitigate these
risks. Another way to mitigate the risk of scripted attacks is to make
the user ID more random and not based on any easily determined format
or commonly available information. There are three aspects of passwords
that contribute to the security they provide: password secrecy, password
length and composition, and administrative controls.
Password
secrecy. The security provided by password-only systems depends on
the secrecy of the password. If another party obtains the password, he
or she can perform the same transactions as the intended user. Passwords
can be compromised because of customer behavior or techniques that capture
passwords as they travel over the Internet. Attackers can also use well-known
weaknesses to gain access to a financial institution's (or its service
provider’s) Internet-connected systems and obtain password files.
Because of these vulnerabilities, passwords and password files should
be encrypted when stored or transmitted over open networks such as the
Internet. The system should prohibit any user, including the system or
security administrator, from printing or viewing unencrypted passwords.
In addition, security administrators should ensure password files are
protected and closely monitored for compromise because if stolen an attacker
may be able to decrypt an encrypted password file.
Financial
institutions need to emphasize to customers the importance of protecting
the password's confidentiality. Customers should be encouraged to log
off unattended computers that have been used to access on-line banking
systems especially if they used public access terminals such as in a library,
institution lobby, or Internet cafe.
Password
length and composition. The appropriate password length and composition
depends on the value or sensitivity of the data protected by the password
and the ability of the user to maintain the password as a shared secret.
Common identification items — for example, dictionary words, proper
names, or social security numbers — should not be used as passwords.
Password composition standards that require numbers or symbols in the
sequence of a password, in conjunction with both upper and lower case
alphabetic characters, provide a stronger defense against password-cracking
programs. Selecting letters that do not create a common word but do create
a mnemonic — for example the first letter of each word in a favorite
phrase, poem, or song — can create a memorable password that is
difficult to crack.
Systems
linked to open networks, like the Internet, are subject to a greater number
of individuals who may attempt to compromise the system. Attackers may
use automated programs to systematically generate millions of alphanumeric
combinations to learn a customer's password (i.e., “brute force”
attack). A financial institution can reduce the risk of password compromise
by communicating and enforcing prudent password selection, providing guidance
to customers and employees, and careful protection of the password file.
Password
administration controls. When evaluating password-based e-banking
systems, management should consider whether the authentication system’s
control capabilities are consistent with the financial institution's security
policy. This includes evaluating such areas as password length and composition
requirements, incorrect log-on lockout, password expiration, repeat password
usage, and encryption requirements, as well as the types of activity monitoring
and exception reports in use.
Each
financial institution must evaluate the risks associated with its authentication
methods given the nature of the transactions and information accessed.
Financial institutions that assess the risk and decide to rely on passwords,
should implement strong password administration standards.
ADMINISTRATIVE
CONTROLS
Action
Summary 
E-banking
activities are subject to the same risks as other banking processes. However,
the processes used to monitor and control these risks may vary because
of e-banking’s heavy reliance on automated systems and the customer’s
direct access to the institution’s computer network. Some of the
controls that help assure the integrity and availability of e-banking
systems are discussed below.
INTERNAL
CONTROLS
Segregation of duties. E-banking support relies on staff in the
service provider’s operations or staff in the institution’s
bookkeeping, customer service, network administration, or information
security areas. However, no one employee should be able to process a transaction
from start to finish. Institution management must identify and mitigate
areas where conflicting duties create the opportunity for insiders to
commit fraud. For example, network administrators responsible for configuring
servers and firewalls should not be the only ones responsible for checking
compliance with security policies related to network access. Customer
service employees with access to confidential customer account information
should not be responsible for daily reconcilements of e-banking transactions.
Dual
controls. Some sensitive transactions necessitate making more than
one employee approve the transaction before authorizing the transaction.
Large electronic funds transfers or access to encryption keys are examples
of two e-banking activities that would typically warrant dual controls.
Reconcilements.
E-banking systems should provide sufficient accounting reports to allow
employees to reconcile individual transactions to daily transaction totals.
Suspicious
activity. Financial institutions should establish fraud detection
controls that could prompt additional review and reporting of suspicious
activity. Some potential concerns to consider include false or erroneous
application information, large check deposits on new e-banking accounts,
unusual volume or size of funds transfers, multiple new accounts with
similar account information or originating from the same Internet address,
and unusual account activity initiated from a foreign Internet address.
Security- and fraud-related events may require the filing of a SAR with
the Financial Crimes Enforcement Network (FinCEN).
Similar
website names. Financial institutions should exercise care in selecting
their website name(s) in order to reduce possible confusion with those
of other Internet sites. Institutions should periodically scan the Internet
to identify sites with similar names and investigate any that appear to
be posing as the institution. Suspicious sites should be reported to appropriate
criminal and regulatory authorities.
Error
checks. E-banking activities provide limited opportunities for customers
to ask questions or clarify their intentions regarding a specific transaction.
Institutions can reduce customer confusion and the potential for unintended
transactions by requiring written contracts explaining rights and responsibilities,
by providing clear disclosures and on-line instructions or help functions,
and by incorporating proactive confirmations into the transaction initiation
process.
On-line
instructions, help features, and proactive confirmations are typically
part of the basic design of an e-banking system and should be evaluated
as part of the initial due diligence process. On-line forms can include
error checks to identify common mistakes in various fields. Proactive
confirmations can require customers to confirm their actions before the
transaction is accepted for processing. For example, a bill payment customer
would enter the amount and date of payment and specify the intended recipient.
But, before accepting the customer’s instructions for processing,
the system might require the customer to review the instructions entered
and then confirm the instruction’s accuracy by clicking on a specific
box or link.
Alternate
channel confirmations. Financial institutions should consider the
need to have customers confirm sensitive transactions like enrollment
in a new on-line service, large funds transfers, account maintenance changes,
or suspicious account activity. Positive confirmations for sensitive on-line
transactions provide the customer with the opportunity to help catch fraudulent
activity. Financial institutions can encourage customer participation
in fraud detection and increase customer confidence by sending confirmations
of certain high-risk activities through additional communication channels
such as the telephone, e-mail, or traditional mail.
BUSINESS
CONTINUITY CONTROLS
E-banking customers often expect 24-hour availability. Service interruptions
can significantly affect customers if the institution offers more than
the most basic services. For example, customer bill payment transactions
may not be paid on time. Due to the potential impact on customers and
customer service, financial institutions should analyze the impact of
service outages and take steps to decrease the probability of outages
and minimize the recovery time if one should occur. Some considerations
include:
| |
Conducting
a business impact analysis of e-banking services that defines the
minimum level of service required and establishes recovery-time objectives; |
| |
Building
redundancy into critical network components to avoid single points
of failure; |
| |
Updating
business continuity plans to address e-banking; |
| |
Developing
customer communication plans prior to an outage; |
| |
Reviewing
the compatibility of key third parties’ business continuity
plans; and |
| |
Periodically
testing business resumption capabilities to determine if objectives
can be met. |
Based on activity volumes, number of customer effected, and the availability
of alternate service channels (branches, checks, etc.), some institutions
may not consider e-banking services as “mission critical“
warranting a high priority in its business continuity plan. Management
should periodically reassess this decision to ensure the supporting rationale
continues to reflect actual growth and expansion in e-banking services.
LEGAL AND COMPLIANCE ISSUES
Action
Summary 
Financial
institutions should comply with all legal requirements relating to e-banking,
including the responsibility to provide their e-banking customers with
appropriate disclosures and to protect customer data. Failure to comply
with these responsibilities could result in significant compliance, legal,
or reputation risk for the financial institution.
TRADE
NAMES ON THE INTERNET
Financial institutions may choose to use a name different from their legal
name for their e-banking operations. Since these trade names are not the
institution’s official corporate title, information on the website
should clearly identify the institution’s legal name and physical
location. This is particularly important for websites that solicit deposits
since persons may inadvertently exceed deposit insurance limits. The risk
management techniques financial institutions should use are based on an
“Interagency Statement for Branch Names” issued May 1, 1998.
Financial
institutions that use trade names for e-banking operations should:
| |
Disclose
clearly and conspicuously, in signs, advertising, and similar materials
that the facility is a division or operating unit of the insured institution;
|
| |
Use
the legal name of the insured institution for legal documents, certificates
of deposit, signature cards, loan agreements, account statements,
checks, drafts, and other similar documents; and |
| |
Train
staff of the insured institution regarding the possibility of customer
confusion with respect to deposit insurance. |
Disclosures
must be clear, prominent, and easy to understand. Examples of how Internet
disclosures may be made conspicuous include using large font or type that
is easily viewable when a page is first opened; inserting a dialog page
that appears whenever a customer accesses a webpage; or placing a simple
graphic near the top of the page or in close proximity to the financial
institution’s logo. These examples are only some of the possibilities
for conspicuous disclosures given the available technology. Front-line
employees (e.g., call center staff) should be trained to ensure that customers
understand these disclosures and mitigate confusion associated with multiple
trade names.
WEBSITE
CONTENT
Financial institutions can take a number of steps to avoid customer confusion
associated with their website content. Some examples of information a
financial institution might provide to its customers on its website include:
| |
The
name of the financial institution and the location of its main office
(and branch offices if applicable); |
| |
The
identity of the primary financial institution supervisory authority
responsible for the supervision of the financial institution's main
office; |
| |
Instructions
on how customers can contact the financial institution's customer
service center regarding service problems, complaints, suspected misuse
of accounts, etc.; |
| |
Instructions
on how to contact the applicable supervisor to file consumer complaints;
and |
| |
Instructions for obtaining information on deposit insurance coverage
and the level of protection that the insurance affords, including
links to the FDIC or NCUA websites at http://www.fdic.gov
or www.ncua.gov,
respectively. |
CUSTOMER PRIVACY AND CONFIDENTIALITY
Maintaining the privacy of a customer’s information is one of the
cornerstones upon which trust in the U.S. banking system is based. Misuse
or unauthorized disclosure of confidential customer data may expose a
financial institution to customer litigation or action by regulatory agencies.
To meet expectations regarding the privacy of customer information, financial
institutions should ensure that their privacy policies and standards comply
with applicable privacy laws and regulations, particularly the privacy
requirements established by GLBA. The regulation implementing GLBA’s
requirements also describes standards on electronic disclosures that apply
if an institution elects to display its privacy policy on its website.
TRANSACTION
MONITORING AND CONSUMER DISCLOSURES
The general requirements and controls that apply to paper-based transactions
also apply to electronic financial services. Consumer financial services
regulations generally require that institutions send, provide,
or deliver disclosures to consumers as opposed to merely making
the disclosures available. Financial institutions are permitted to provide
such disclosures electronically if they obtain consumers’ consent
in a manner consistent with the requirements of the federal Electronic
Signatures in Global and National Commerce Act (the E-Sign Act). The Federal
Reserve Board has issued interim rules providing guidance on how the E-Sign
Act applies to the consumer financial services and fair lending laws and
regulations administered by the Board.
However mandatory compliance with the interim rules was not required at
the time of this booklet’s publication.
Financial
institutions may provide electronic disclosures under their existing policies
or practices, or may follow the interim rules, until the Board issues
permanent rules.
When
disclosures are required to be in writing, the E-Sign Act requires that
financial institutions generally must obtain a consumer’s affirmative
consent to provide disclosures electronically. Under the E-Sign Act, a
consumer must among other things provide such consent electronically and
in a manner that reasonably demonstrates that he or she can access the
electronic record in the format used by the institution. In addition,
the institution must advise customers of their right to withdraw their
consent for electronic disclosures and explain any conditions, consequences,
or fees triggered by withdrawing such consent.
Additional
information on consumer regulatory requirements can be found in this booklet’s
“Compliance/Legal Risk” section and on each agency’s
website.
