| Description | ||||
| Passwords must be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised. Passwords that are encrypted with a weak algorithm are no more protected than if they are kept in plain text. Using more hashing rounds makes password cracking attacks more difficult.

Check Text (C-282459r1200357_chk)
Verify TOSS 5 has a minimum number of hash rounds configured using the following command:
$ grep -i sha_crypt /etc/login.defs
If "SHA_CRYPT_MIN_ROUNDS" or "SHA_CRYPT_MAX_ROUNDS" is less than "5000", this is a finding.
Fix Text (F-86925r1200356_fix)
Configure TOSS 5 to encrypt all stored passwords with a strong cryptographic hash.
Edit/modify the following line in the "/etc/login.defs" file and set "SHA_CRYPT_MIN_ROUNDS" to a value no lower than "5000":
SHA_CRYPT_MIN_ROUNDS 5000
