General availability: Default Rule Set 2.1 for Azure Web Application Firewall

We are announcing the general availability of the Default Rule Set 2.1 (DRS 2.1) on Azure's global Web Application Firewall (WAF) running on Azure Front Door. This rule set is available on the Azure Front Door Premium tier.

DRS 2.1 is baselined off the Open Web Application Security Project (OWASP) Core Rule Set (CRS) 3.3.2 and includes additional proprietary protections rules developed by Microsoft Threat Intelligence team. As with previous DRS releases, DRS 2.1 rules are also tailored by Microsoft Threat Intelligence Center (MSTIC). The MSTIC team analyzes Common Vulnerabilities and Exposures (CVEs) and adapts the CRS ruleset to address those issues while also reducing false positives to our customers.
