Check: GEN005507
HP-UX 11.31 STIG:
GEN005507
(in versions v1 r19 through v1 r13)
Title
The SSH daemon must be configured to only use Message Authentication Codes (MACs) employing FIPS 140-2 approved cryptographic hash algorithms. (Cat II impact)
Discussion
DoD information systems are required to use FIPS 140-2 approved cryptographic hash functions.
Check Content
Check the SSH daemon configuration for allowed MACs. Note that keywords are case-insensitive and arguments (args) are case-sensitive. Examine the file. # cat /opt/ssh/etc/sshd_config | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' | grep -v '^#' | egrep -i "macs" If no lines are returned, or the returned MACs list contains any MAC that is not hmac-sha1 or a better hmac algorithm that is on the FIPS 140-2 approved list, this is a finding.
Fix Text
Edit the SSH daemon configuration and remove any MACs that are not hmac-sha1 or a better hmac algorithm that is on the FIPS 140-2 approved list. If necessary, add a MACs line.
