# Security controls and web application firewall

This guide describes security controls implemented on ROLLER sites to block malicious internet traffic and steps to rectify if you believe you have been blocked for no valid reason.

## Overview

ROLLER has implemented a web application firewall (WAF) service that detects, logs and blocks insecure activity such as bad reputation IP addresses, tor, SQL injection or a malicious pattern being detected. This malicious internet traffic is blocked before it can damage your sites.

## Security error message

When the WAF service blocks internet traffic, users (eg staff, guests) see the following security error message:
