Cybersecurity First Principles

• Each part of the "hand" works together as a whole unit, just like each of your fingers and the palm. As such, each principle is dependent on the next - when one is compromised or not optimal, the entire system is compromised.Defense in Depth – Multiple layers of security controls are put into place within a system to protect information; the multiple layers of security are in place in case one layer fails, another layer of security is already in place to stop the attack/unauthorized access.
• Confidentiality– The property that information is not disclosed to unauthorized individuals, entities, or processes; preserving authorized restrictions on information access and disclosure, including means for protecting personal privacy and proprietary information.
• Integrity- Assurance that information is accurate and trustworthy; information must be protected from unauthorized modification/change.
• Availability– Information is accessible to authorized persons.
• Think Like an Adversary– A thinking process that considers the potential actions of the opposing force (adversary) working against the desired result; ability to anticipate the actions of your adversary and build security measures to defend your information/network – ultimately preventing unauthorized access and loss of data.
• Keep It Simple – Value of keeping computer programming/system design simple without compromising the ability to protect information/data from unauthorized access.
