Document Summary

Cia model summarized below: confidentiality: preserving authorized restrictions on information access and disclosure, including means for protecting personal privacy and proprietary information. A loss of confidentiality is the unauthorized disclosure of information. Integrity: guarding against improper information modification or destruction, including ensuring information non-repudiation and authenticity. A loss of integrity is the unauthorized medication or destruction of information: availability: ensuring timely and reliable access to and use of information. A loss of availability is the disruption of access to or use of information or an information system. Additional concepts: authenticity: the property of being genuine and being able to be verified and trusted; confidence in the validity of a transmission, a message, or message originator. This supports non- repudiation, deterrence, fault isolation, intrusion detection and prevention, and after-action recovery and legal action. Because truly secure systems aren"t yet an achievable goal, we must be able to trace a security breach to a responsible party.
