Description
Authorization for access to any IDPS requires an approved and assigned individual account identifier. To ensure only the assigned individual is using the account, the account holder must create a strong password that is privately maintained and changed based on the organizationally defined frequency. Password strength is a measure of the effectiveness of a password in resisting guessing, dictionary attacks, as well as, brute-force attacks. A password must have an expiration date to limit the amount of time a compromised password can be used by a malicious user. However, changing the password too frequently may result in the user changing a small portion of the password, or the user could mishandle the password in an attempt to remember the new password.

Check Text ( C-43285_chk )
View the password configuration for local accounts. Verify the system is configured so the value for the minimum password lifetime restriction is set to an organizationally defined value. If the value for the minimum lifetime restriction is not set to an organizationally defined value, this is a finding.
