What is System Attack

A system attack is a malicious attempt to compromise a computer system, targeting vulnerabilities in software, hardware or human behavior. Examples include malware, phishing, and denial-of-service attacks. Cybersecurity measures like firewalls, antivirus software, and user training are used to prevent and mitigate these attacks.
