QRadar EDR (formerly ReaQta): What does "Aggressive Mode" in ReaQta Anti-Malware do?

Question & Answer


Question

What does the "Aggressive" setting in ReaQta's Anti-Malware module do, and why is it not suggested one not have it enabled all the time?

In the IBM Documentation Enabling the Anti-Malware module, there are 4 levels of Anti-Malware protection:
  • Detection
  • Protection
  • Advanced
  • Aggressive
What does Aggressive do, and why is it not suggested it not be enabled all the time?
 

Answer

  • The Anti-Malware module does not support on-demand scan, but continuously monitors the file system for changes. This scanning is default behavior.
  • In Aggressive mode, every mounted drive gets monitored and scans are run for every application and file, including system folders. If malware is found, it is quarantined and kept locally in a protected directory.
  • Aggressive mode is suggested during a breach or attack, to keep monitoring all drives. Once the breach is declared over, it is suggested one set the Anti-Malware level back to its non-aggressive stance. It is said this behavior can be seen similar to deep vs regular scanning in various Anti-Virus solutions to verify against the presence of malware artifacts.
  • Aggressive mode is not ideal for day-to-day use, as it might have a performance impact in the long term where it is used.
