A signature-based security program is a type of security software that identifies malware using well-known, pre-recorded digital signatures or identifiers. These programs identify malware by cross-referencing a suspicious program's digital signatures with the digital signatures of existing malware software which have been stored in a database specifically designed to archive and help identify a wide array of documented malware types.
