Question 90
A Microsoft 365 tenant wants stronger detection of internal account-takeover email and approved remediation rights. Which Cisco security control or operational response BEST addresses the stated need?
Explanation
Correct Answer
Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. This control addresses the failure mechanism and narrows the enforcement boundary. Email Threat Defense uses message and behavioral context; an authenticated sender domain or clean attachment does not prove a message is safe. Confirm pre-change conditions using: Inspect sender authentication, impersonation indications, inbound/outbound message direction, detection verdict, and remediation authorization. Situation: A Microsoft 365 tenant wants stronger detection of internal account-takeover email and approved remediation rights.
Incorrect Answers
Prioritize Secure Endpoint alerts by severity, current host risk, file action, correlated detections, and business criticality. This response applies to Endpoint malware event prioritization, not the controlling requirement in this case. Alert counts alone do not establish incident severity; containment status and evidence of active execution change urgency. For this scenario, the targeted action is: Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. Situation: A Microsoft 365 tenant wants stronger detection of internal account-takeover email and approved remediation rights.
Evaluate endpoint security posture before authorizing sensitive network access and establish a restricted remediation path for failed devices. This response applies to Posture check before network access, not the controlling requirement in this case. Posture is device health evidence used in policy; authentication alone does not guarantee an endpoint meets security baseline. For this scenario, the targeted action is: Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. Situation: A Microsoft 365 tenant wants stronger detection of internal account-takeover email and approved remediation rights.
Choose supported Email Threat Defense supplementary mailbox visibility or inline gateway enforcement according to platform and pre-delivery requirements. This response applies to Email Threat Defense deployment mode selection, not the controlling requirement in this case. Cisco ETD deployment options differ: a supplemental mailbox visibility path and a supported gateway path have different enforcement timing and platform prerequisites. For this scenario, the targeted action is: Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. Situation: A Microsoft 365 tenant wants stronger detection of internal account-takeover email and approved remediation rights.
