   What is the primary purpose of an attack surface rule in XSIAM?

   • ATo encrypt all traffic between endpoints and the cloud
   • BTo automatically patch vulnerabilities in the network infrastructure
   • CTo reduce the attack surface by identifying and blocking suspicious behaviors
   • DTo replace the need for a firewall by providing network segmentation

   An analyst is creating an attack surface rule to detect suspicious network connections. The rule should trigger when a connection is made to a known malicious IP address OR when a connection is made to an unusual port, but only if the process is 'svchost.exe'. How should the rule be structured?

   • ACreate two separate trigger blocks: one for 'svchost.exe' + malicious IP and another for 'svchost.exe' + unusual port.
   • BCreate one trigger block for 'svchost.exe' and add two filters: one for the malicious IP and one for the unusual port, with OR logic between the filters.
   • CCreate a trigger block for 'svchost.exe' and add the malicious IP as a filter, then create a second trigger block for the unusual port.
   • DCreate a single trigger block for the malicious IP and add 'svchost.exe' and the unusual port as filters with AND logic.

   A company is deploying XSIAM and wants to reduce its attack surface by preventing known malicious file downloads. The security team is unsure whether to use an attack surface rule with a 'block' action or rely on existing detection content that only alerts. What is the primary advantage of using the 'block' action in an attack surface rule for this scenario?

   • AIt ensures the rule never produces false positives because blocking is more precise than alerting.
   • BIt immediately stops the malicious activity, reducing the chance of compromise while still generating an alert for review.
   • CIt automatically deletes the malicious file from the endpoint without requiring analyst intervention.
   • DIt bypasses the need for additional detection content, making all other security controls unnecessary.

   Which method can be used to test an attack surface rule in XSIAM?

   • ADeleting the rule and recreating it
   • BChanging the rule's action to 'allow'
   • CRunning a simulation with sample events
   • DDisabling the rule and observing network traffic

   An organization is deploying an attack surface rule to detect and prevent a newly discovered exploitation technique. The rule must stop the attack immediately, but the security team also wants to maintain visibility into the activity for further analysis. Which action should the rule use?

   • AAlert
   • BAllow
   • CLog only
   • DBlock
