Question

question 6 / 7 what is signature-based detection? relies on pre-defined patterns or signatures detect malicious activities by observing behavior of software, systems, and users over time way of quarantining and removing viruses looks for suspicious behavior or properties in files

Explanation:

Signature - based detection in the context of cybersecurity (a subfield of Computer Science, which is under Natural Science) is a method that uses pre - defined patterns or signatures (like hash values of known malware, specific code snippets) to identify malicious entities. The second option describes behavior - based detection, the third is about virus removal/quarantine (not detection), and the fourth is more about heuristic or behavior - based analysis of files. So the correct description of signature - based detection is that it relies on pre - defined patterns or signatures.

Answer:

A. Relies on pre - defined patterns or signatures
