General availability: Bot Manager Rule Set 1.0 on regional Web Application Firewall

A new bot protection rule set (Microsoft_BotManagerRuleSet_1.0) is now generally available for Azure Web Application Firewall (WAF) with Azure Application Gateway. Added to this updated rule set are three bot categories - good, bad, and unknown. Bot signatures are managed and dynamically updated by Azure WAF. 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. You may overwrite the default action with Allow, Block, or Log for any type of bot rule.
