Check: GEN001369

Solaris 10 X86 STIG: GEN001369 (in versions v2 r4 through v1 r17)

Title

The /etc/hosts file must not have an extended ACL. (Cat II impact)

Discussion

The /etc/hosts file (or equivalent) configures local host name to IP address mappings that typically take precedence over DNS resolution. If this file is maliciously modified, it could cause the failure or compromise of security functions requiring name resolution, which may include time synchronization, centralized authentication, and remote system logging.

Check Content

Verify /etc/hosts has no extended ACL. # ls -lL /etc/hosts If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix Text

Remove the extended ACL from the file. # chmod A- /etc/hosts
