Kona Site Defender providing content filtering must protect against known types of denial-of-service (DoS) attacks by employing signatures.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-76423	AKSD-WF-000020	SV-91119r1_rule		Medium

Description
If the network does not provide safeguards against DoS attacks, network resources may not be available to users during an attack. Installation of content filtering gateways and application layer firewalls at key boundaries in the architecture mitigates the risk of DoS attacks. These attacks can be detected by matching observed communications traffic with patterns of known attacks and monitoring for anomalies in traffic volume, type, or protocol usage. Detection components that use signatures can detect known attacks by using known attack signatures. Signatures are usually obtained from and updated by the ALG component vendor. This requirement applies to the communications traffic functionality of the ALG as it pertains to handling communications traffic, rather than to the ALG device itself.

Confirm Kona Site Defender is configured to block traffic for organizationally defined HTTP protocol violations, HTTP policy violations, SQL injection, remote file inclusion, cross-site scripting, command injection attacks, and any applicable custom rules: 1. Log in to the Akamai Luna Portal (https://control.akamai.com). 2. Click the "Configure" tab. 3. Under the "Security" section, select "Security Configuration". 4. If prompted for which product to use, select "Site Defender" and then "Continue". 5.

The detailed "Security Configuration" page will load listing the protected host names and applicable policies. 7. Select the policy being reviewed. 8. Verify the "Application Layer Controls" checkbox is enabled. 9. Verify the following "KRS Rule Set" rules are set to "Deny". - SQL Injection - Cross Site Scripting (XSS) - Command Injection - Invalid HTTP - Remote File Inclusion - PHP Injection (when PHP is used) - Trojan - Total Request Scor4e (Inbound) - Total Response Score (Outbound) - DDOS 10. Verify the "Enabled Slow POST Protection" section appears. If the application layer controls are not set to "Deny" mode or slow POST protection does not appear, this is a finding.
