350-701 Network Security Practice Question
A security analyst is monitoring the Cisco FMC and notices a high number of false positives from an intrusion rule that detects SQL injection attempts. The legitimate web application frequently generates similar patterns. Which course of action would reduce false positives while maintaining detection for actual attacks?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the rule's threshold to reduce frequency.
Modifying the rule's threshold to require a higher number of matches or using a suppression filter for the web server IP can reduce false positives.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable the rule entirely.
Why it's wrong here
Disabling removes detection capability.
- ✗
Create a new intrusion rule with opposite logic.
Why it's wrong here
This would be complex and may not effectively reduce false positives.
- ✗
Change the rule action to 'pass'.
Why it's wrong here
Pass disables inspection for all traffic matching the rule.
- ✓
Increase the rule's threshold to reduce frequency.
Why this is correct
Thresholding can reduce alerts from repeated patterns while still triggering on high volume.
