  • A. Create a sensor visibility exclusion for "C:\Users\Bob\DevCode\felix.dll"
  • B. Create an IOA exclusion for "C:\Users\Bob\DevCode\felix.dll"
  • C. Create a Custom IOC and set it to "Allow" for "C:\Users\Bob\DevCode\felix.dll"

Selected Answer: B
B. Create an IOA exclusion for "C:\Users\Bob\DevCode\felix.dll" In this situation, the alert is triggered by a specific Falcon Indicator of Attack (IOA), so the best course of action would be to create an IOA exclusion for the specific file path to prevent Falcon from flagging it during testing. This allows the development process to continue without compromising overall security, as the exclusion is targeted and specific to the identified IOA.

Answer is B because the detection was for an IOA. If you allow the hash of the DLL via a Custom IOC it will only affect Machine Learning based detections and not IOAs, which means it cannot be C
