Fix Recommendation

Configure the Ubuntu operating system to encrypt all stored passwords.

Edit/Modify the following line in the "/etc/login.defs" file and set "ENCRYPT_METHOD" to SHA512.

ENCRYPT_METHOD SHA512

Check Contents

Verify that the shadow password suite configuration is set to encrypt password with a FIPS 140-2 approved cryptographic hashing algorithm.

Check the hashing algorithm that is being used to hash passwords with the following command:

# cat /etc/login.defs | grep -i crypt

ENCRYPT_METHOD SHA512

If "ENCRYPT_METHOD" does not equal SHA512 or greater, this is a finding.
