What is Intrusion?

Intrusion, in the context of cybersecurity, refers to any unauthorized activity or attempt to access a computer system, network, or data. Intrusion attempts can take many forms, including malware infections, hacking attempts to exploit vulnerabilities, social engineering, or physical breaches.
