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. |

From the command prompt, run the following command to check the system default "minupperalpha" attribute value: # lssec -f /etc/security/user -s default -a minupperalpha The above command should yield the following output: default minupperalpha=1 If the default "minupperalpha" value is not set, or its value is less than "1", this is a finding. From the command prompt, run the following command to check "minupperalpha" attribute value for all accounts: # lsuser -a minupperalpha ALL The above command should yield the following output: root minupperalpha=2 user2 minupperalpha=2 user3 minupperalpha=1 If any user's "minupperalpha" value is less than "1", this is a finding. |
