CAT II

CCI(s)

• CCI-000068 - The information system implements cryptographic mechanisms to protect the confidentiality of remote access sessions.
• CCI-000197 - The information system, for password-based authentication, transmits only cryptographically-protected passwords.
• CCI-000213 - The information system enforces approved authorizations for logical access to information and system resources in accordance with applicable access control policies.
• CCI-000803 - The information system implements mechanisms for authentication to a cryptographic module that meet the requirements of applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance for such authentication.
• CCI-001188 - The information system generates unique session identifiers for each session with organization-defined randomness requirements.
• CCI-001453 - The information system implements cryptographic mechanisms to protect the integrity of remote access sessions.
• CCI-002418 - The information system protects the confidentiality and/or integrity of transmitted information.
• CCI-002422 - The information system maintains the confidentiality and/or integrity of information during reception.
• CCI-002470 - The information system only allows the use of organization-defined certificate authorities for verification of the establishment of protected sessions.

Fix Recommendation

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file:

# httpd -V | egrep -i 'httpd_root|server_config_file'
-D HTTPD_ROOT="/etc/httpd"
-D SERVER_CONFIG_FILE="conf/httpd.conf"

Ensure the "SSLProtocol" is added and looks like the following:

SSLProtocol -ALL +TLSv1.2

Restart Apache: apachectl restart

Check Contents

In a command line, run "httpd -M | grep -i ssl_module".

If the "ssl_module" is not found, this is a finding.

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file:

# httpd -V | egrep -i 'httpd_root|server_config_file'
-D HTTPD_ROOT="/etc/httpd"
-D SERVER_CONFIG_FILE="conf/httpd.conf"

Search for the "SSLCACertificateFile" directive:

# cat /<path_to_file>/httpd.conf | grep -i "SSLCACertificateFile"

Review the path of the "SSLCACertificateFile" directive.

Review the contents of <'path of SSLCACertificateFile'>\ca-bundle.crt.

Examine the contents of this file to determine if the trusted CAs are DoD approved.

If the trusted CA that is used to authenticate users to the website does not lead to an approved DoD CA, this is a finding.

NOTE: There are non-DoD roots that must be on the server for it to function. Some applications, such as antivirus programs, require root CAs to function. DoD-approved certificate can include the External Certificate Authorities (ECA) if approved by the AO. The PKE InstallRoot 3.06 System Administrator Guide (SAG), dated 08 Jul 2008, contains a complete list of DoD, ECA, and IECA CAs.
