Signature-based Detection

Signature-based detection is a method used by cybersecurity systems to identify malware or cyber threats by recognizing known patterns or "signatures" in files or code. These signatures are like unique fingerprints for malicious software, built from analyzing past threats. When a new file is scanned, the system compares its code to these signatures. If a match is found, it flags the file as potentially harmful. This approach effectively detects known threats but may struggle with new or modified malware that doesn't match existing signatures.
