As the Chief Information Security Officer (CISO) for a publicly traded company, there are a few protections I would set in place to ensure the availability of the systems. Some of these systems correspond to maintaining operations, protecting customer information, and regulating requirements. I would implement a few steps and protections to guarantee the system’s availability. I would first regularly ensure systems are strong and up to date with tests. This would be very useful in the case of an unexpected disaster such as cyberattacks or other events. This would aid in the recovery time and keep our company trustworthy. Another protection is providing proper cybersecurity training and informing employees about the system’s importance and its role in aiding against threats. With both the systems and employees working together for the protection of the availability of the systems, this will secure and defend the system.
