To answer this question, we need to understand what graceful degradation means in the context of a denial-of-service (DoS) attack. Graceful degradation refers to the ability of software to continue functioning, albeit at a reduced capacity or performance, when faced with an attack or failure.

Let's go through each option to understand why it is correct or incorrect:

Option A) Fail-over to a higher-availability service - This option is incorrect. Fail-over to a higher-availability service typically refers to redirecting traffic to a backup system or server, which may not be possible during a DoS attack.

Option B) Vary its response times to subsequent requests - This option is correct. Software can exhibit graceful degradation by intentionally varying its response times to subsequent requests during a DoS attack. By slowing down response times, the software can prioritize legitimate requests and reduce the impact of the attack.

Option C) Disconnect the affected connectivity point - This option is incorrect. Disconnecting the affected connectivity point may help isolate the attack, but it doesn't directly exhibit graceful degradation.

Option D) Fail-over to a hot standby - This option is incorrect. Failing over to a hot standby is a form of redundancy where a backup system takes over when the primary system fails. It doesn't directly exhibit graceful degradation in response to a DoS attack.

The correct answer is Option B. This option is correct because varying the response times to subsequent requests allows the software to prioritize legitimate requests and continue functioning, albeit at a reduced capacity or performance, during a DoS attack.

To answer this question, you need to understand the concept of "security-through-obscurity" and the corresponding security design principle.

Option A) Defense-in-depth - This option is incorrect. Defense-in-depth is a security design principle that advocates for implementing multiple layers of security measures to protect against potential threats. It does not specifically address the practice of "security-through-obscurity."

Option B) Open design - This option is correct. Open design is a security design principle that emphasizes the importance of not relying on secrecy or hiding security mechanisms. It promotes the idea that security should be based on the strength of the design and not on keeping the design secret. Therefore, it aligns with the practice of "Security should not depend on security-through-obscurity."

Option C) Complete mediation - This option is incorrect. Complete mediation is a security design principle that focuses on the concept of ensuring that every access to a system or resource is checked and authorized. It does not directly relate to the practice of "security-through-obscurity."

Option D) Analyzability - This option is incorrect. Analyzability is a security design principle that emphasizes the importance of being able to analyze and understand the security mechanisms and design of a system. While it is related to the overall security of a system, it does not specifically address the practice of "security-through-obscurity."

The correct answer is B) Open design. This option is correct because it aligns with the principle that "Security should not depend on security-through-obscurity." Open design promotes the idea that security should be based on the strength of the design and not on keeping the design secret.

To answer this question, you need to understand the concept of trust features in a software application.

Option A) Security management interfaces - This option is correct because security management interfaces provide control over the trust features in a software application. These interfaces allow administrators to configure and manage the security settings of the application, including trust-related features such as authentication, authorization, and encryption.

Option B) Secure configuration management - While secure configuration management is important for overall security, it does not specifically provide control over trust features in a software application.

Option C) Application container - An application container is a runtime environment that isolates an application and its dependencies from the underlying operating system. While it can contribute to the overall security of an application, it does not specifically provide control over trust features.

Option D) Security manager - A security manager is responsible for enforcing security policies within an application. While it plays a role in the overall security of the application, it does not specifically provide control over trust features.

The correct answer is A) Security management interfaces. This option is correct because security management interfaces provide control over the trust features in a software application.
