As the CISO of a company some of the protections I would implement are the several types of automated tools to monitor a system. One of the most important tools I would use is the malicious code scanner to be aware of any present and unwanted codes or viruses. I would also conduct penetration testing and system assesments . I would conduct the penetration test weekly to help determine the possible consequences of a possible attack, so I can be aware and be two steps a head if it were to happen. I would also evaluate the entire system periodically to authorize and or investigate the events being performed. Most importantly as the CISO I would follow the guidelines emplaced on how to things more securely within the organization.
