|Alert Message||Atomicorp.com WAF Rules: Fake msnbot/bingbot webcrawler|
This exclusive capability in the Atomicorp ruleset can detect when a client pretends to be the bing webcrawler. This helps to detect and block potential zero day and other supsicious behavior. Attacks have been know to impersonate webcrawlers to trick naive applications that blinding trust webcrawlers. They use this method to gain access that would otherwise be blocked to non-crawlers.
This will not block the real bing webcrawler. We do not recommend you disable this rule.
For ASL users, if you enable the option below, ASL will automatically and dynamically whitelist the real bing webcrawler from all WAF events:
