What is a key characteristic of signature-based detection systems?

Signature-based detection systems are primarily defined by their reliance on a database of known attack signatures. This characteristic allows these systems to identify and respond to threats by comparing incoming data against a catalog of known malicious patterns. If a match is found, an alert is triggered, indicating a recognized attack.

This method is effective for detecting specific threats that have already been identified and documented. Signature-based systems are especially useful in environments where the patterns of known attacks are well-understood, allowing for quick and efficient detection. However, they may be less effective against new and evolving threats that have not yet been added to the database, which is an important aspect to consider in the overall security strategy.
