Question 230
A SOC needs to triage an encrypted connection but its only evidence is the destination port 443. Which observed result BEST confirms that the security requirement is met?
Explanation
Correct Answer
Investigators can associate suspicious encrypted connections with affected devices while private payload content remains protected. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. Encrypted traffic analytics can leverage metadata and behavior; encryption reduces payload visibility and does not make a flow automatically benign. Situation: A SOC needs to triage an encrypted connection but its only evidence is the destination port 443.
Incorrect Answers
The corrected handshake establishes valid security associations without weakening approved encryption or authentication standards. This outcome tests FTD IKE negotiation failure isolation and is not sufficient proof of the stated requirement. Here the relevant validation is: Investigators can associate suspicious encrypted connections with affected devices while private payload content remains protected. Situation: A SOC needs to triage an encrypted connection but its only evidence is the destination port 443.
Tested exploit traffic is detected or blocked by the configured policy while legitimate services remain available. This outcome tests FTD intrusion policy and malware detection and is not sufficient proof of the stated requirement. Here the relevant validation is: Investigators can associate suspicious encrypted connections with affected devices while private payload content remains protected. Situation: A SOC needs to triage an encrypted connection but its only evidence is the destination port 443.
Firewall and switch events share consistent time ordering and protected transport to the authorized log collector. This outcome tests Secure syslog and timestamp correlation and is not sufficient proof of the stated requirement. Here the relevant validation is: Investigators can associate suspicious encrypted connections with affected devices while private payload content remains protected. Situation: A SOC needs to triage an encrypted connection but its only evidence is the destination port 443.
