Committee on National Security Systems:
The CNSS (Committee on National Security Systems) security model shows the three dimensions of Information Security. It excludes any discussion of policies and guidelines that directs the control implication and is necessary for an effective information security system program.
Following are the dimensions of CNSS security model:
• Confidentiality
• Integrity
• Availability
• Policy
• Education
• Technology
• Storage
• Processing
• Transmission
The main reason behind this model is to find out gaps in the coverage of an information security system program. CNSS includes three dimensions and are represented as three cubes. The relationships between the cubes are represented by the axes 3x3x3=27 cells. The intersection among these cells represents issues that are to be addressed to secure information systems.
