SV-34015r1_rule Web sites must utilize ports, protocols, and services according to PPSM guidelines.

Vulnerability discussion

Failure to comply with DoD ports, protocols, and services (PPS) requirements can resultin compromise of enclave boundary protections and/or functionality of the AIS.The IAM will ensure web servers are configured to use only authorized PPS in accordance with the Network Infrastructure STIG, DoD Instruction 8551.1, Ports, Protocols, and Services Management (PPSM), and the associated Ports, Protocols, and Services (PPS) Assurance Category Assignments List.

Check content

Review the web site to determine if HTTP and HTTPs are used in accordance with well known ports (e.g., 80 and 443) or those ports and services as registered and approved for use by the DoD PPSM. Any variation in PPS will be documented, registered, and approved by the PPSM. If not, this is a finding.

Fix text

Ensure the web site enforces the use of IANA well-known ports for HTTP and HTTPS.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
