Signature Database

A Signature Database is a collection of unique identifiers—called signatures—that are used by security systems to recognize and detect malicious software or files. These signatures are specific patterns or codes associated with known threats. When a new file is examined, the system compares its signature to the database. If a match is found, it indicates the file may be harmful. This method helps quickly identify and prevent infections by referencing known threat signatures, making it an essential tool in cybersecurity for maintaining system safety.
