while others are like waiting in line for a Saturday night movie.

Planning Weblinking Relationships
Due Diligence
A financial institution should conduct sufficient due diligence
to determine whether it wishes to be associated with the quality of
products, services, and overall content provided by third-party
sites. A financial institution should consider more product-focused
due diligence if the third parties are providing financial products,
services, or other financial website content. In this case,
customers may be more likely to assume the institution reviewed and
approved such products and services. In addition to reviewing the
linked third-party's financial statements and its customer service
performance levels, a financial institution should consider a review
of the privacy and security policies and procedures of the third
party.8 Also, the financial institution
should consider the character of the linked party by considering its
past compliance with laws and regulations and whether the linked
advertisements might by viewed as deceptive advertising in violation
of Section 5 of the Federal Trade Commission Act.

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.

Initial Privacy Notice
3) Does the institution provide to existing customers, who
obtain a new financial product or service, an initial privacy notice
that covers the customer's new financial product or service, if the
most recent notice provided to the customer was not accurate with
respect to the new financial product or service? [§4(d)(1)]
