text: Generating a session identifier (ID) that is not easily guessed through brute force is essential to deter several types of session attacks. By knowing the session ID, an attacker can hijack a user session that has already been user authenticated by the hosted application. The attacker does not need to guess user identifiers and passwords or have a secure token since the user session has already been authenticated. Generating session IDs that are at least 128 bits (16 bytes) in length will cause an attacker to take a large amount of time and resources to guess, reducing the likelihood of an attacker guessing a session ID.
  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.
