WEB SITE COMPLIANCE -
Electronic Fund Transfer Act, Regulation E (Part 2 of 2)
Additionally, the regulations clarifies that a written authorization
for preauthorized transfers from a consumer's account includes an
electronic authorization that is not signed, but similarly
authenticated by the consumer, such as through the use of a security
code. According to the
Official Staff Commentary (OSC,) an example of a consumer's
authorization that is not in the form of a signed writing but is,
instead, "similarly authenticated," is a consumer's authorization
via a home banking system.
To satisfy the regulatory requirements, the institution must
have some means to identify the consumer (such as a security code)
and make a paper copy of the authorization available (automatically
or upon request). The
text of the electronic authorization must be displayed on a computer
screen or other visual display that enables the consumer to read the
communication from the institution. Only the consumer may authorize
the transfer and not, for example, a third-party merchant on behalf
of the consumer.
Pursuant to the regulations, timing in reporting an unauthorized
transaction, loss, or theft of an access device determines a
consumer's liability. A
financial institution may receive correspondence through an
electronic medium concerning an unauthorized transaction, loss, or
theft of an access device.
Therefore, the institution should ensure that controls are in place
to review these notifications and also to ensure that an
investigation is initiated as required.

AUTHENTICATION -
Shared Secret Systems (Part 1 of 2)
Shared secret systems uniquely identify the user by matching
knowledge on the system to knowledge that only the system and user
are expected to share. Examples are passwords, pass phrases, or
current transaction knowledge. A password is one string of
characters (e.g., "t0Ol@Tyme"). A pass phrase is typically a string
of words or characters (e.g., "My car is a shepherd") that the
system may shorten to a smaller password by means of an algorithm.
Current transaction knowledge could be the account balance on the
last statement mailed to the user/customer. The strength of shared
secret systems is related to the lack of disclosure of and about the
secret, the difficulty in guessing or discovering the secret, and
the length of time that the secret exists before it is changed.
A strong shared secret system only involves the user and the system
in the generation of the shared secret. In the case of passwords and
pass phrases, the user should select them without any assistance
from any other user, such as the help desk. One exception is in the
creation of new accounts, where a temporary shared secret could be
given to the user for the first login, after which the system
prompts the user to create a different password. Controls should
prevent any user from re - using shared secrets that may have been
compromised or were recently used by them.
Passwords are the most common authentication mechanism. Passwords
are generally made difficult to guess when they are composed from a
large character set, contain a large number of characters, and are
frequently changed. However, since hard - to - guess passwords may
be difficult to remember, users may take actions that weaken
security, such as writing the passwords down. Any password system
must balance the password strength with the user's ability to
maintain the password as a shared secret. When the balancing
produces a password that is not sufficiently strong for the
application, a different authentication mechanism should be
considered. Pass phrases are one alternative to consider. Due to
their length, pass phrases are generally more resistant to attack
than passwords. The length, character set, and time before enforced
change are important controls for pass phrases as well as passwords.
Shared secret strength is typically assured through the use of
automated tools that enforce the password selection policy.
Authentication systems should force changes to shared secrets on a
schedule commensurate with risk.
Passwords can also be dynamic. Dynamic passwords typically use
seeds, or starting points, and algorithms to calculate a new -
shared secret for each access. Because each password is used for
only one access, dynamic passwords can provide significantly more
authentication strength than static passwords. In most cases,
dynamic passwords are implemented through tokens. A token is a
physical device, such as an ATM card, smart card, or other device
that contains information used in the authentication process.

INTERNET PRIVACY - We continue our
series listing the regulatory-privacy examination questions.
When you answer the question each week, you will help ensure
compliance with the privacy regulations.
Consumer and Customer:
The distinction between consumers and customers is
significant because financial institutions have additional
disclosure duties with respect to customers. All customers covered
under the regulation are consumers, but not all consumers are
customers.
A "consumer" is an individual, or that individual's legal
representative, who obtains or has obtained a financial product or
service from a financial institution that is to be used primarily
for personal, family, or household purposes.
A "financial service" includes, among other things, a financial
institution's evaluation or brokerage of information that the
institution collects in connection with a request or an application
from a consumer for a financial product or service. For example, a
financial service includes a lender's evaluation of an application
for a consumer loan or for opening a deposit account even if the
application is ultimately rejected or withdrawn.
Consumers who are not customers are entitled to an initial privacy
and opt out notice only if their financial institution wants to
share their nonpublic personal information with nonaffiliated third
parties outside of the exceptions.
A "customer" is a consumer who has a "customer relationship" with a
financial institution. A "customer relationship" is a continuing
relationship between a consumer and a financial institution under
which the institution provides one or more financial products or
services to the consumer that are to be used primarily for personal,
family, or household purposes. |
