A security architect is designing a strategy to help continue operating in the face of a cyber-attack. Which of the following will help to accomplish this objective?

To maintain operational continuity despite a cyber-attack, it is essential to have a robust strategy in place. This strategy typically includes measures that enhance resilience, establish redundancy, and promote quick recovery.

The selection of 1, 2, and 3 includes elements that likely focus on proactive defense mechanisms and response plans that enable the organization to withstand and mitigate the impact of cyber threats. This might involve implementing security controls designed to deter attacks, maintaining up-to-date incident response plans, and conducting regular training for teams to ensure that they are prepared to act effectively in case of an incident.

A proactive approach such as this is critical for ensuring that necessary systems remain operational and that business functions can continue with minimal disruption. Each of these components likely contributes to an overall strategy that equips the organization with the tools and frameworks necessary to respond effectively to attacks, thereby ensuring that it can operate even under adverse conditions.

In contrast, the other combinations may lack one or more of these integral components, which are vital for an effective continuity strategy during a cyber-attack. Elements not included in the selected combination may not provide the same level of comprehensive support for ongoing operations, highlighting the importance of a well-rounded approach to cyber resilience.
