STIGQter: STIG Summary: Apache Server 2.4 UNIX Server Security Technical Implementation Guide Version: 2 Release: 2 Benchmark Date: 22 Jan 2021:

The Apache web server must generate a session ID long enough that it cannot be guessed through brute force.

Group Title

SRG-APP-000224-WSR-000137

• CCI-001188 - The information system generates unique session identifiers for each session with organization-defined randomness requirements.

Weight

Fix Recommendation

Configure the web server to generate session identifiers that are at least 128 bits in length.

Ensure that "session_crypto_module" is enabled.

Determine the location of the "httpd.conf" file by running the following command:

httpd -V

Review the "HTTPD_ROOT" path.

Navigate to the "HTTPD_ROOT"/conf directory.

Edit the "httpd.conf" file.

SessionCryptoCipher aes256

Restart Apache: apachectl restart

Check Contents

Review the web server documentation and deployed configuration to determine the length of the generated session identifiers.

First ensure that "session_crypto" is enabled:

httpd -M |grep session_crypto

If the above command returns "session_crypto_module", the module is enabled in the running server.

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"

Review the "httpd.conf" file.

If the "SessionCryptoCipher" is not used or "SessionCryptoCipher" is not set to "aes256", this is a finding.
