On this episode of Life of a CISO, I teach you three core prerequisites to be a successful CISO. If you do not have these three minimum requirements to be a successful CISO, you will fail at your job, and you will get fired. It may very well not be your fault that you get fired, because if the CEO does not agree to give you the authority it takes to be an effective CISO, your job is already as good as lost. Therefore, you must advocate for yourself.

Here are the three prerequisites: 1, the CISO must be equal to other vice presidents, like the CIO. This is because security has a specific metric for success: Uptime. The goal of the CIO is to have the service be available 99.999% of the time (called 5 Nines), and this means that time spent shutting down the servers for maintenance and patching takes away from his bonus. Therefore the CISO must be able to have equal authority, so that the CEO can decide whether to favor security or uptime. 2: Have a metric. As I just mentioned, the CIO wants 5 nines uptime. The metric I have come up with is how many attempted attacks in a given period of time. It’s not perfect, but I’ve yet to hear a better one. 3: Have security KPIs in place. This means that you must test security and have a measurable outcome that you can report on. For example, run a phishing campaign on your own company. If the phishing campaign produces a low amount of successful phishing attacks (but you’re very unlikely to have 100% success), security is effective at your organization. If you have these prerequisites, you can be an effective CISO; if not, you might want to keep some copies of your resume nearby, because you will unfairly lose your job as a CISO before you know it.
