What does the term 'DoS' refer to in penetration testing?

• A. Denial of Service, an attack aimed at making a service unavailable.
• B. A measure to protect devices from overheating.
• C. A method to decrypt traffic.
• D. A technique to exploit DNS caching.

Answer: (A)

Denial of Service is a type of attack aimed at making a service unavailable to legitimate users by overwhelming it with traffic or exhausting its resources (CPU, memory, bandwidth). In penetration testing, the goal is to assess how resilient a system is to such disruption and how well the organization can detect, mitigate, and recover from it, all with proper authorization. The other options describe different concepts (hardware protection, traffic decryption, or DNS cache exploitation) and do not capture the core aim of DoS, which is to disrupt service availability.
