Web Application Firewall—New bot protection rule now in preview
Updated: December 09, 2019
A new bot protection ruleset (Microsoft_BotManagerRuleSet_1.0) is now in preview for Azure Web Application Firewall with Azure Front Door service. Adding to this updated ruleset are three bot categories—good, bad, and unknown. There are multiple bot groups within each category. Bot signatures are managed and dynamically updated by Web Application Firewall service. The default action for bad bot groups is set to Block, for the verified search engine crawlers group it’s set to Allow, and for the unknown bot category it’s set to Log. Customers may overwrite the default action with Allow, Block, Log, or Redirect for any type of bot groups.
