Check: PHTN-67-000026
VMware vSphere 6.7 Photon OS STIG:
PHTN-67-000026
(in versions v1 r6 through v1 r1)
Title
The Photon operating system must store only encrypted representations of passwords. (Cat II impact)
Discussion
Passwords must be protected at all times via strong, one-way encryption. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised. If they are encrypted with a weak cipher, those passwords are much more vulnerable to offline brute forcing attacks.
Check Content
At the command line, execute the following command: # grep SHA512 /etc/login.defs|grep -v "#" Expected result: ENCRYPT_METHOD SHA512 If there is no output or if the output does match the expected result, this is a finding.
Fix Text
Open /etc/login.defs with a text editor. Add or replace the ENCRYPT_METHOD line as follows: ENCRYPT_METHOD SHA512
