Frequently Asked
Questions (FAQs)
1.
What happens if I delete the persistent cookie by deleting cookies/clears
cache. Will it be written again at the
next login and the customer prompted to accept it again if their browser is set
to prompt?
• If the user deletes his cookies, a new
cookie with a new machine value will be added once he has successfully
authenticated.
• If the user has the setting to prompt for cookies they will be
prompted every time a new cookie is created.
2.
What does the message look like when accepting a cookie?
• The verbiage of the message is the same one they receive today
for the required session cookies within NetTeller. Below is an example from
Internet Explorer.

3.
What information is stored in the persistent cookies? What if the cookie is
copied and placed on another computer? Is the cookie encrypted?
• The cookie is a hashed value that is created by the Banks’
core system administrator. The value includes several things used to protect
your identity and account information.
• The cookie cannot be placed on another computer.
• The cookie is encrypted.
4.
What is the benefit of using a persistent cookie, how does it impact RSA?
• The persistent cookie is a unique cookie that does not change
between user sessions, commonly used to save preferences of a user to ease
navigation. RSA uses it for positive device tagging. This way the user and the
cookie are associated with a profile. As long as the user is coming from the
same cookie, then the system is more trusted. If the user has succeeded in
passing a challenge then the trust is even greater. If the user fails
authentication or is marked as fraud confirmed this will help in future
transactions.
5.
Can my user’s cookie be used by a hacker / fraudster?
• Cookie interception through the use of malware or Trojans that
have been installed onto a user’s PC can occur. In those scenarios, the cookie
is one of many pieces of data that the fraudster can access including ID and
password information through a keystroke program.
• The capturing of cookies is not a complete guarantee against
fraud but it is a strong deterrent. Therefore it is important to remember to
consider multiple layers of protection.
• Cookies that are passed to RSA from NetTeller are encrypted to
ensure that data can’t be captured from the cookie should a user’s PC become
compromised.
