Assessment Title

Rule Text

The Stream Control Transmission Protocol (SCTP) must be disabled unless required.

Description

Discussion Text

The SCTP is an IETF-standardized transport layer protocol. This protocol is not yet widely used. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause the kernel to dynamically load a protocol handler by opening a socket using the protocol.

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.

  exit 1

Remediation

Configure the system to prevent the dynamic loading of the SCTP protocol handler.
