When the virtual machine has IPS rule 1002313 deployed and the Intrusion Prevention Behavior is set to Prevent, the HTTP traffic is blocked but the HTTPs traffic is not.
For example, using Firefox to open "http://www.yahoo.com" is blocked by IPS rule 1002313. However, opening "https://www.yahoo.com" cannot be blocked.
This is an expected behavior. By design, Intrusion Prevention does not inspect the outgoing HTTPs traffic.
