ACF2-ES-000860
(in versions v9 r2 through v8 r8)
Title
ACF2 PSWD GSO record value must be set to require at least one lowercase character be used. (Cat II impact)
Discussion
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password complexity is one factor of several that determines how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that need to be tested before the password is compromised.
