What Is a Cyber Attack?
a Cyber Attack — any deliberate attempt to damage, disrupt, or gain unauthorised access to computer systems, networks or data — from malware and phishing to DDoS and intrusion.
How it works
Cyber attacks range widely: malware infections, phishing for credentials, DDoS floods, exploiting software vulnerabilities, insider misuse, and more. Most follow a recognisable pattern (see the cyber kill chain): reconnaissance, gaining access, escalating, and acting on objectives like stealing data or disruption.
Why it matters
Understanding the categories of cyber attack — and how they map to the defences that stop them — is the foundation of security work. It's why organisations build SOCs, deploy firewalls and IDS/IPS, and train staff. A core CyberOps concept.
Frequently asked questions
What is a cyber attack?
Any deliberate attempt to damage, disrupt or gain unauthorised access to systems, networks or data — including malware, phishing, DDoS and intrusion.
What are the most common types of cyber attacks?
Phishing, malware (including ransomware), DDoS, credential attacks, and exploitation of software vulnerabilities are among the most common.
How do organisations defend against cyber attacks?
Layered defences — firewalls, IDS/IPS, endpoint protection, MFA, patching, monitoring via a SOC, and user training — since no single control stops everything.
