Question 540
A finance vendor's updater is flagged by endpoint security and an administrator proposes excluding the entire system drive. Which Cisco security control or operational response BEST addresses the stated need?
Explanation
Correct Answer
Scope endpoint detection exclusions narrowly and verify business application behavior after updates without disabling broad antimalware protections. This control addresses the failure mechanism and narrows the enforcement boundary. Broad folder or process exclusions can create lasting blind spots; false-positive tuning requires evidence and defined review dates. Confirm pre-change conditions using: Inspect exclusion path or hash, triggering detection, business impact, owner approval, and endpoint policy revision. Situation: A finance vendor's updater is flagged by endpoint security and an administrator proposes excluding the entire system drive.
Incorrect Answers
Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. This response applies to Email Threat Defense anti impersonation controls, not the controlling requirement in this case. Email Threat Defense uses message and behavioral context; an authenticated sender domain or clean attachment does not prove a message is safe. For this scenario, the targeted action is: Scope endpoint detection exclusions narrowly and verify business application behavior after updates without disabling broad antimalware protections. Situation: A finance vendor's updater is flagged by endpoint security and an administrator proposes excluding the entire system drive.
Configure Cisco Secure Endpoint policy groups, detection and blocking settings, and connector deployment aligned to host risk. This response applies to Cisco Secure Endpoint antimalware policy, not the controlling requirement in this case. Endpoint policy efficacy depends on correct host enrollment, file disposition, behavior detection, and controlled exclusions. For this scenario, the targeted action is: Scope endpoint detection exclusions narrowly and verify business application behavior after updates without disabling broad antimalware protections. Situation: A finance vendor's updater is flagged by endpoint security and an administrator proposes excluding the entire system drive.
Choose endpoint prevention, behavioral detection, and response capabilities based on business risk and investigation needs rather than equating antivirus with EDR. This response applies to Endpoint protection versus detection response, not the controlling requirement in this case. EPP focuses preventative controls and EDR records and investigates suspicious endpoint activity and supports response; the capabilities overlap but are not interchangeable. For this scenario, the targeted action is: Scope endpoint detection exclusions narrowly and verify business application behavior after updates without disabling broad antimalware protections. Situation: A finance vendor's updater is flagged by endpoint security and an administrator proposes excluding the entire system drive.
