The password hashes stored on the system must have been generated using a FIPS 140-2 approved cryptographic hashing algorithm.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-63235	ESXI-06-000033	SV-77725r1_rule		Medium

Description
Systems must employ cryptographic hashes for passwords using the SHA-2 family of algorithms or FIPS 140-2 approved successors. The use of unapproved algorithms may result in weak password hashes more vulnerable to compromise.

Check Text ( C-63969r1_chk )
To verify the password hash setting, run the following command: # grep -i "^password" /etc/pam.d/passwd \| grep sufficient If sha512 is not listed, this is a finding.

Fix Text (F-69153r1_fix)
To set the remember option, add or correct the following line in "/etc/pam.d/passwd": password sufficient /lib/security/$ISA/pam_unix.so use_authtok nullok shadow sha512 remember=5
