There are four main methods of detecting cyber threats, which include:n1. Firewalls: These are software or hardware devices that monitor and control incoming and outgoing network traffic based on predetermined security rules.n2. Antivirus software: These programs scan for and remove malware from computers, servers, and other devices.n3. Intrusion detection and prevention systems (IDPS): These systems monitor network traffic and identify suspicious activity that may indicate an attempted cyber-attack.n4. Vulnerability scanning: This involves using specialized software to scan networks and systems for weaknesses that cybercriminals can exploit.
