Check for Presence of User .netrc Files

HighLevel 1Automatedsolaris

Description

The .netrc file contains data for logging into a remote host for file transfers via FTP. The .netrc file presents a significant security risk since it stores passwords in unencrypted form. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

How it is checked

Audit method: Shell command

shell

command -v logins >/dev/null 2>&1 || exit 1; out=$( { for dir in $(logins -ox | awk -F: '($8 == "PS") { print $6 }'); do ls -l "$dir"/.netrc; done ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Correct or justify any items discovered in the Audit step. Determine if any .netrc files exist, and work with the owner to determine the best course of action in accordance with site policy.
