Signature Analysis

Comparing files to a repository of known threats (think of this like looking up a mugshot). When a sequence of bytes (known as a signature) matches a previously seen piece of malware, Signature Analysis knows to block the download or action. This is one of the most common forms of virus protection, but it’s important to pair it with Machine Learning, Heuristic Analysis, or Behavior Analysis to prevent unknown (zero-day) threats.
