WG140 IIS6 - A private web sites authentication mechanism must use client certificates. - 'AccessSSLRequireCert Enabled'

Information

A DoD private web site must utilize PKI as an authentication mechanism for web users. Information systems residing behind web servers requiring authorization based on individual identity shall use the identity provided by certificate-based authentication to support access control decisions. Not using client certificates allows an attacker unauthenticated access to private web sites.

Solution

1. Open the IIS Manager > Right click on the website being reviewed > Select Properties > Select the Directory Security tab.
2. Under the Secure communications area select the Edit button.
3. Select Require secure channel (SSL) and Require client certificates > Press OK.
