ITPEC IP April 2023 Question 37
ITPEC IP April 2023 — Question 37 of 100
A denial-of-service attack directly interrupts or degrades the server's services. The attacker exhausts bandwidth, connections, CPU, memory, or application capacity with traffic or expensive requests so legitimate users cannot obtain timely service. The primary security property harmed is availability.
Answer (d)
Why not others:
- (a) decrypting protected data would be a confidentiality failure, not the defining result of DoS
- (b) changing an administrator password requires account compromise or unauthorized modification
- (c) virus infection is malware compromise and is not what defines denial of service
Key rule: DoS targets availability by preventing legitimate use; DDoS produces the attack from many distributed sources.
