name: Ensure Strong Password Hashing Algorithm is Configured

author: Th3l0newolf

description: |
|
|
The ENCRYPT_METHOD setting in /etc/login.defs specifies the algorithm used to hash passwords.It should be set to SHA512 or yescrypt, as weaker algorithms may expose passwords to brute-force attacks.
|
|
remediation: |
|
|
Edit /etc/login.defs and set ENCRYPT_METHOD to either SHA512 or yescrypt.Verify with: grep -Pi -- '^\h*ENCRYPT_METHOD\h+(SHA512|yescrypt)\b' /etc/login.defs
