General availability: Improvements to Azure Web Application Firewall (WAF) custom rules
Published date: 20 September, 2022
New operators on regional WAF custom rules:
Azure regional Web Application Firewall (WAF) with Application Gateway now supports creating custom rules using the operators "Any" and "GreaterThanOrEqual". Custom rules allow you to create your own rules to customize how each request is evaluatedas it passes through the WAF engine.
To learn more about creating custom rules, please visit the regional WAF documentation.
Geo filtering using socket address on global WAF:
Azure global Web Application Firewall (WAF) with Azure Front Door now supports custom geo-match filtering rules using socket addresses. Filtering by socket address allows you to restrict access to your web application by country/region using the source IP that the WAF sees. If your user is behind a proxy, socket address is often the proxy server address.
