Assessment Title

Rule Text

There must be no user .rhosts files.

Description

Discussion Text

Even though the .rhosts files are ineffective if support is disabled in /etc/pam.conf, they may have been brought over from other systems and could contain information useful to an attacker for those other systems.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

SCC Automation Reference

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

export HOME=$(getent passwd $(whoami) | cut -d: -f6)
for user in $(cut -d: -f1 /etc/passwd); do
  rhosts_file="$HOME/.rhosts"
  if [ -f "$rhosts_file" ]; then
    echo "FAIL"
    exit 1
  fi
done
echo "PASS"
exit 0

Remediation

The root role is required.

Remove any .rhosts files found.

# rm [file name]
