Description

The KeepAliveTimeout directive specifies the number of seconds Apache will wait for a subsequent request before closing a connection that is being kept alive.

Rationale

The KeepAliveTimeout directive is used mitigate some of the risk, by requiring more effort for a successful DoS attack. By enabling KeepAlive and keeping the timeout relatively low for old connections and we allow the server to free up resources more quickly and be more responsive.

Remediation

KeepAliveTimeout 15
