Group Title

SRG-APP-000157

Rule Version

APSC-DV-001630

Severity

CAT II

CCI(s)

• CCI-001942 - The information system implements replay-resistant authentication mechanisms for network access to non-privileged accounts.

Weight

10

Fix Recommendation

Design and configure the application to utilize replay-resistant mechanisms when authenticating non-privileged accounts.

Check Contents

Review the application documentation and interview the application administrator to identify what authentication mechanisms are used when accessing the application.

If the application is hosting publicly releasable information that does not require authentication, or if the application users are not eligible for a DoD CAC as per DoD 8520, this requirement is not applicable.

Review to ensure the application is utilizing TLSV1.2 or greater to protect communication and non-privileged user authentication traffic.

Verify the application utilizes a strong authentication mechanism such as Kerberos, IPSEC, or Secure Shell (SSH).

- Cryptographically sign web services packets.
- Time stamps and cryptographic hashes are used with web services packets.
- Use WS_Security for web services.

Request the most recent vulnerability scan results and configuration settings.

Verify the configuration is set to test for known replay vulnerabilities.

Request code review results (if available) and review for issues that have been identified as potential replay attack vulnerabilities.

Verify identified issues have been remediated.

If the application is not implementing replay-resistant authentication methods applicable to the application architecture, this is a finding.
