Denial-of-Service Attack is defined as which of the following?

• A. Exfiltrates data
• B. Prevents legitimate use of a company\'s resources
• C. Hijacks user sessions
• D. Defends against attacks

Answer: (B)

Denial-of-Service attacks aim to make a service or resource unavailable to legitimate users by flooding it with traffic or exploiting weaknesses so normal operations halt. That focus on disrupting access directly matches the idea of preventing legitimate use of a company's resources. Exfiltrating data involves stealing information, not denying access. Hijacking user sessions targets taking over active connections, a different threat than making services unavailable. Defending against attacks is the opposite of what a DoS does. In short, a DoS attack compromises availability, leading to downtime and unusable services.
