TOSS 5 passwords, for new users, must have a minimum of 15 characters.

The shorter the password, the lower the number of possible combinations that must be tested before the password is compromised.

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password. Use of more characters in a password helps to increase exponentially the time and/or resources required to compromise the password.

The DoW minimum password requirement is 15 characters.

Verify TOSS 5 enforces a minimum 15-character password length for new user accounts using the following command:

$ sudo grep -i  pass_min_len /etc/login.defs

PASS_MIN_LEN 15

If the command does not return a "PASS_MIN_LEN" value of "15" or greater, does not return a line, or the line is commented out, this is a finding.

Configure TOSS 5 to enforce a minimum 15-character password length for new user accounts.

Add or modify the following line in the "/etc/login.defs" file:

PASS_MIN_LEN 15
