Non-privileged accounts on the hosting system must only access Apache web server security-relevant information and functions through a distinct administrative account.
By separating Apache web server security functions from non-privileged users, roles can be developed that can then be used to administer the Apache web server. Forcing users to change from a non-pr...Rule Medium Severity -

The Apache web server must generate log records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT) which are stamped at a minimum granularity of one second.
If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis across multiple devices and log records. Time stamps generated by th...Rule Medium Severity -

The Apache web server must be protected from being stopped by a non-privileged user.
An attacker has at least two reasons to stop a web server. The first is to cause a denial of service (DoS), and the second is to put in place changes the attacker made to the web server configurati...Rule Medium Severity -

The Apache web server software must be a vendor-supported version.
Many vulnerabilities are associated with older versions of web server software. As hot fixes and patches are issued, these solutions are included in the next version of the server software. Maintai...Rule High Severity -

The Apache web server must limit the number of allowed simultaneous session requests.
Apache web server management includes the ability to control the number of users and user sessions that utilize an Apache web server. Limiting the number of allowed users and sessions per user is h...Rule Medium Severity -
The Apache web server must perform server-side session management.
Session management is the practice of protecting the bulk of the user authorization and identity information. This data can be stored on the client system or on the server. When the session inform...Rule Medium Severity -
The Apache web server must use cryptography to protect the integrity of remote sessions.
Data exchanged between the user and the Apache web server can range from static display data to credentials used to log on to the hosted application. Even when data appears to be static, the non-di...Rule Medium Severity -
The Apache web server must generate, at a minimum, log records for system startup and shutdown, system access, and system authentication events.
Log records can be generated from various components within the Apache web server (e.g., httpd, plug-ins to external backends, etc.). From a web server perspective, certain specific Apache web serv...Rule Medium Severity -
An Apache web server, behind a load balancer or proxy server, must produce log records containing the client IP information as the source and destination and not the load balancer or proxy IP information with each event.
Apache web server logging capability is critical for accurate forensic analysis. Without sufficient and accurate information, a correct replay of the events cannot be determined. Ascertaining the ...Rule Medium Severity -
The Apache web server must use a logging mechanism that is configured to alert the Information System Security Officer (ISSO) and System Administrator (SA) in the event of a processing failure.
Reviewing log data allows an investigator to recreate the path of an attacker and to capture forensic data for later use. Log data is also essential to SAs in their daily administrative duties on t...Rule Medium Severity -
The Apache web server log files must only be accessible by privileged users.
Log data is essential in the investigation of events. If log data were to become compromised, competent forensic analysis and discovery of the true source of potentially malicious system activity w...Rule Medium Severity -
