Why do you see two events generated for the same signature (one as Detected and other as Blocked)?
This is normal behavior and is due to the way the Protocol Analysis Module (PAM) event coalescer works.
When a signature fires, PAM will include the details of the traffic that caused it to fire in the event data. Certain events, such as scans and sweeps, may delay the collection of this data due to the nature of the traffic. If PAM is still in the process of collecting all of the event details, the event will show as having a "Detected" status. Once the collection of information is complete, the event will show as having a "Blocked" status.
In most cases, the two events are combined prior to being sent to SiteProtector. However, in situations where there was a delay or timeout while waiting for the rest of the information, users may see both the Detected and Blocked events in the SiteProtector Console. This is not indicative of a problem.
