In cybersecurity, what is the purpose of redundancy?

• A. To increase system efficiency
• B. To enhance and ensure availability
• C. To manage information access
• D. To protect against unauthorized access

Answer: (B)

Redundancy in cybersecurity is primarily aimed at enhancing and ensuring availability. This concept involves having multiple instances of critical components, such as servers, network paths, or data storage, so that if one component fails or becomes compromised, others can take over seamlessly without interrupting service. This capability is crucial during downtime due to maintenance or unexpected incidents, ensuring that systems remain operational and that users have continuous access to necessary resources. In a redundant setup, if a primary system fails, the redundant system can activate to maintain operations, significantly limiting the risk of downtime. This strategy is especially vital for organizations that require high availability for their services, such as in cloud computing environments or financial institutions, where interruptions can lead to substantial losses and negatively affect user trust. While efficiency, information access management, and protection against unauthorized access are critical in cybersecurity, they do not directly correlate with the concept of redundancy. Redundancy's key role is to maintain system functionality and availability in the event of failures or attacks.
