# Ensure KeepAliveTimeout is Set to a Value of 15 or Less (Automated)

## Profile Applicability

- Level 1

## 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.

## Audit

Perform the following steps to determine if the recommended state is implemented: Verify that the `KeepAliveTimeout` directive in the Apache configuration to have a value of `15` or less. If the directive is not present the default value is `5` seconds.

## Remediation

Perform the following to implement the recommended state: Add or modify the `KeepAliveTimeout` directive in the Apache configuration to have a value of `15` or less.

```apache
KeepAliveTimeout 15
```

## Default Value

```apache
KeepAliveTimeout 5
```
