Signature-based file scanning relies primarily on what?

Signature-based file scanning relies primarily on what?

• A. Real-time system monitoring
• B. Previously detected malware characteristics
• C. User behavior analysis
• D. Network traffic patterns

Answer: (B)

The correct answer is based on the principle that signature-based file scanning primarily involves identifying and mitigating threats by referencing characteristics of known malware. This method works by scanning files and comparing them to a database of signatures, which are unique patterns or characteristics associated with previously detected malware. When a match is found, the system can take appropriate actions, such as quarantining or deleting the file. Signature-based detection is highly effective for known threats, as it provides a direct method to identify and block malware that has already been cataloged based on its unique attributes. This approach forms the backbone of many antivirus and anti-malware solutions, as it allows for quick and efficient identification of familiar threats. Other methods, such as real-time system monitoring, user behavior analysis, and network traffic patterns, serve different purposes in the realm of cybersecurity. While they are valuable components of a broader security strategy, they do not specifically relate to the fundamental mechanism of signature-based file scanning, which is reliant on previously established malware signatures.
