In this discussion board, you are the CISO for a publicly traded company. What protections would you implement to ensure availability of your systems (and why)?

If I were the CISO of a publicly traded company, I would first develop an incident response plan. This would help limit the damage when a security breach happens by laying out exactly what to do, like how to spot it, contain it, get rid of the threat and recover. I would also implement regular drills and simulations to test the effectiveness of the response plan. I would include tabletop exercises and full-scale simulations to prepare for different types of incidents. I would also implement a security awareness training program to educate employees about common threats and provide guidance on how to recognize and respond to these threats.
