Assessment Title

Rule Text

The securetcpip command must be used.

Description

Discussion Text

The AIX securetcpip command disables insecure network utilities, such as rcp, rlogin, rlogind, rsh, rshd, tftp, tftpd, and trpt/d. These services increase the attack surface of the system.

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

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.

# OVAL Definition: oval:mil.disa.fso.aix11:def:5


if [ -f /etc/security/config.1 ]; then
    if grep -q "^tcpip:$" /etc/security/config.1; then
        if [ -f /etc/securetcpip ]; then
            echo "PASS"
            exit 0
        else
            echo "FAIL"

Remediation

Ensure secure tcp/ip has been invoked before allowing operations on the system.
