How does redundancy improve network security?

Redundancy plays a significant role in enhancing network security by implementing backup systems or connections. This approach ensures that if one system, path, or connection fails or becomes compromised, an alternative can immediately take over without disrupting network operations. For example, if a primary server is attacked or goes down, a redundant backup server can provide continuity, ensuring that services remain available and reducing the risk of downtime. This not only protects against potential data loss but also serves to mitigate the impact of a security breach.

By having multiple layers or options, organizations can create a more resilient infrastructure that can withstand various types of threats—be it hardware failures, cyberattacks, or natural disasters. Effective redundancy strategies often include having backup internet connections, failover clustered servers, or redundant switches. This not only protects the integrity and availability of data but also enhances the network’s overall security posture.

The other choices do not align directly with the concept of redundancy as it pertains to security. For instance, simply increasing traffic speeds does not inherently provide better security, nor does simplifying user authentication processes or reducing data storage needs directly contribute to maintaining secure backups of critical network components.
