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. Password length is one factor in determining password strength. Use of a longer password string will exponentially increase the time and/or resources required to compromise the password. Information systems not protected with strong password schemes including passwords of minimum length provide the opportunity for anyone to crack the password thus gaining access to the system and causing the device, information, or the local network to be compromised or a denial of service. This control applies to passwords configured or controlled by the IDPS itself.

Check Text ( C-42894r1_chk )
If authentication functionality is provided by the underlying platform's account management system or by a network authentication server rather than the IDPS application itself, this is not a finding.

Review the IDPS account management configuration and settings to determine whether the minimum password length is configured.

If the IDPS configuration does not enforce a minimum password length, this is a finding.
