• Question 5:

  Which Exploit Protection Module (EPM) can be used to prevent attacks based on OS function?

  A. UASLR
  B. JIT Mitigation
  C. Memory Limit Heap Spray Check
  D. DLL Security
  B. JIT Mitigation

  ---

  Explanation

  JIT Mitigation is an Exploit Protection Module (EPM) that can be used to prevent attacks based on OS function. JIT Mitigation protects against exploits that use the Just-In-Time (JIT) compiler of the OS to execute malicious code. JIT Mitigation monitors the memory pages that are allocated by the JIT compiler and blocks any attempts to execute code from those pages. This prevents attackers from using the JIT compiler as a way to bypass other security mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR).

  C. Network: This is not the correct answer. Network is not a type of BIOC rule that is currently available in Cortex XDR. Network is an event type that can be used in a Discovery BIOC rule to define the criteria based on network attributes, such as source IP, destination IP, source port, destination port, protocol, or domain. Network is not a standalone type of BIOC rule, but a part of the Discovery BIOC rule2.

  D. Dropper: This is not the correct answer. Dropper is not a type of BIOC rule that is currently available in Cortex XDR. Dropper is a term that refers to a type of malware that is designed to download and install other malicious files or programs on a compromised system. Cortex XDR does not support creating BIOC rules based on droppers, but it can detect and prevent droppers using various methods, such as behavioral threat protection, exploit prevention, or WildFire analysis4. In conclusion, the type of BIOC rule that is currently available in Cortex XDR is Discovery. By using Discovery BIOC rules, you can create custom detection rules that match your specific use cases and scenarios.
