Assessment Title

Rule Text

Network interfaces must not be configured to allow user control.

Description

Discussion Text

Configuration of network interfaces should be limited to privileged users. Manipulation of network interfaces may result in a Denial of Service or bypass of network security mechanisms.

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.

if [ ! -d "/etc/sysconfig/network-scripts" ]; then echo "PASS"; exit 0; fi
for file in /etc/sysconfig/network-scripts/ifcfg.*; do if [ -f "$file" ]; then grep -q "^USERCTL[ \t]*=[ \t]*yes" "$file" && { echo "FAIL"; exit 1; }; fi; done; echo "PASS"; exit 0;

Remediation

Edit the configuration for the user-controlled interface and remove the "USERCTL=yes" configuration line or set to "USERCTL=no".
