While there are several of protections to ensure availability of my system, if I was the CISO for a publicly traded company, the top three protections would be Distributed Denial of Service Mitigation (DDoS) and network security, data backup and disaster recovery, and redundancy and high availability architecture.
First, I chose DDoS and network security because the Distributed Denial of service (DDoS) mitigation and network security allows measurements that help protect and secure against cyber threats. They ensure that the users can legitimately access the company’s systems without a cyber disruption. Second, I would use data backup and disaster recovery. This is need because losing everything you have worked for would be devastating. By using this, this ensures that all critical information needed within the community can be quickly restored if data corruption, system failures, or deletion of data occurs. Lastly, I would use redundancy and high availability architecture. I would use this because it helps distribute the traffic of the cyber world as well as maintaining operations even if another server goes down, which corresponds with data backup and disaster recovery.
