Becoming a Virtual CISO: Everything You Need to Know
On this episode, we take a moment to define cyber security. It’s a term we use every day, but few of us actually stop to think about the actual definition, understanding, managing, and mitigating risk of your critical data from being disclosed, altered or denied
There are 3 components to cyber security:
- Risk – Understanding historical and comparative data to understand where to put your resources
- Critical data – If you want to be a good CISO, you have to be obsessed with where the physical data is, who has access to it, and how it is being protected.
- CIA – Confidentiality, Integrity, and Availability.
Resources (money & time) are finite resources. I have an exercise called “the pie chart.” In this exercise, the executive uses a pie chart to show which of these three has the highest and lowest priorities. In order to be a successful CISO, the CISO and the executive team must have their priorities in alignment with each other.
