In cybersecurity, what type of malicious attack overwhelms a web server with massive volumes of traffic from multiple compromised sources to render it unavailable to legitimate users?
Answer and explanation
Correct answer: D. Distributed Denial of Service (DDoS) attack
- Step 1: A Distributed Denial of Service (DDoS) attack employs a botnet of geographically dispersed compromised devices.
- Step 2: The botnet floods target servers with bogus traffic (e.g., SYN floods, UDP floods), exhausting bandwidth and computational capacity to deny access to legitimate users.
Answer
Distributed Denial of Service (DDoS) attack.
Why not the others: 'SQL injection' manipulates backend databases via input fields; 'XSS' injects malicious client-side scripts into web pages; 'Phishing' uses deceptive communications to steal credentials.
