Which cyber event category involves suspicious activity that requires further review?

The correct choice pertains to the category of suspicious activity known as Malicious Logic (Incident). This category specifically encompasses the detection of software-based malicious activities, such as viruses, worms, or Trojans, that can compromise the integrity and security of computer systems. When an incident involving malicious logic is identified, it signifies that there is an active threat potentially impacting the network, prompting an immediate and thorough review to prevent any data breaches or system disruptions.

Unlike other categories that may represent non-compliance or general suspicious activity, malicious logic incidents indicate a direct threat that necessitates swift investigation to mitigate any risks associated with the potential spread of harmful code or unauthorized access to systems. Understanding and identifying these types of incidents is crucial in network security, as they often require specialized responses to contain and eliminate the threat posed by malicious software.
