Summary
After a security rule update is pushed and applied to Deep Security, certain Intrusion Prevention rules are observed to change the default mode from "Detect Only" to "Prevent".
Details
Public
Intrusion Prevention rules can be prone to false positive detections. To ensure these incidents are minimized, rules for important applications are first shipped in "Detect Only" Mode as part of the process.
We monitor this for some time and when confirmed to have no false detections, the rules are then converted to "Prevent" Mode in the next rule update. This process is only done for rules affecting server applications.
Note: An exception to this are important and high risk vulnerability that are always shipped in "Prevent" Mode.
