Question 36

Availability

Implementing a product that offers protection against DDoS attacks primarily focuses on ensuring the availability of resources and services. This security concept is critical as DDoS attacks aim to overwhelm systems, making them unavailable to legitimate users.

A) Availability

This option is correct because the primary goal of protecting against DDoS attacks is to maintain the availability of network services. By mitigating these attacks, organizations ensure that their systems remain operational and accessible to users, thus supporting the availability aspect of security.

B) Non-repudiation

Non-repudiation refers to the assurance that someone cannot deny the validity of their signature or the sending of a message. It is not directly related to DDoS attacks, as the focus here is on maintaining service access rather than proving actions or communications.

C) Integrity

Integrity involves ensuring that data is accurate and unaltered. While maintaining integrity is important in security, it does not directly address the issues posed by DDoS attacks, which primarily disrupt availability rather than compromise data integrity.

D) Confidentiality

Confidentiality pertains to protecting information from unauthorized access. Although it is an essential aspect of security, it does not relate to the challenges posed by DDoS attacks, which target the accessibility of services rather than the secrecy of information.

Conclusion

The concept of availability is crucial when addressing DDoS attacks, as these attacks are designed to disrupt access to services. All other options—non-repudiation, integrity, and confidentiality—do not focus on maintaining service availability, which is the primary concern during such attacks. Therefore, availability is the definitive correct answer in this context.
