Why is information systems security important to the DoD?

• Information systems security begins at the top and concerns everyone. Security is all too often regarded as an afterthought in the design and implementation of C4I systems. In fact, the importance of information systems security must be felt and understood at all levels of command and throughout the DOD.

How to design a Secure Computing Base ( TCB )?

Security must be a factor in system design from the beginning. It starts with defining the trusted computing base (TCB). Follow these steps to achieve a secure system.

What makes a computer system a secure system?

Follow these steps to achieve a secure system. A secure system is built around the principles of a trusted computing base (TCB), which incorporates mechanisms for identifying and authenticating users (I&A), controlling access to system objects, and auditing users’ actions.
