Again, including it below to make the thread easier to follow.
- "IPS Most Important Not Prevented" means IPS signatures that were triggered but are set in Detect Mode. This could easily be zero depending on what signatures were triggered.
- "IPS Follow Up" means IPS signatures that were triggered that are tagged for followup. Again, this could easily be zero depending on what signatures were triggered.
Important Security Events will also include IPS events.
