Which describes Denial of Service Attacks?

• A. Authentication Attacks
• B. Denial of Service Attacks
• C. Integrity Attacks
• D. Availability Attacks

Answer: (B)

Denial of Service attacks aim to make a service unavailable to legitimate users by overwhelming it with traffic or exhausting its resources, causing outages or severe slowdowns. The focus is on denying access rather than stealing data or altering information, which is why this description fits best. Authentication attacks try to bypass login credentials, while integrity attacks involve tampering with data. Availability attacks is a broader term about disrupting service availability, but the specific action and intent of Denial of Service attacks are captured most precisely by naming them directly.
