cyberstrikeus Ensure KeepAlive Is Enabled (Automated)
Profile Applicability
- Level 1
Description
The KeepAlive directive controls whether Apache will reuse the same TCP connection per client to process subsequent HTTP requests from that client. It is recommended that the KeepAlive directive be set to On.
Rationale
Allowing per-client reuse of TCP sockets reduces the amount of system and network resources required to serve requests. This efficiency gain may improve a server's resiliency to DoS attacks.
Audit
Perform the following steps to determine if the recommended state is implemented: Verify that the KeepAlive directive in the Apache configuration to have a value of On, or is not present. If the directive is not present the default value is On.
Remediation
Perform the following to implement the recommended state: Add or modify the KeepAlive directive in the Apache configuration to have a value of On, so that KeepAlive connections are enabled.
KeepAlive On
Default Value
KeepAlive On
