Then our security officer hung some gas masks on the wall, to be available for people that happened to be in that zone. Someone then pointed out that a normal gas mask filters out toxic materials but cannot aid when the air lacks oxygen! Anyway, the security officer continued his methods of physical security by ordering 20 mm caliber cannons to be placed at the entrance of the computing facility, securing against possible raids from the university area across the street. 1 Some Basic Concepts The Communication Perspective A formal definition of information is closely related to the theory of communication, so we will derive some of the basic concepts of information security by studying the simple model of communication: two independent entities, a sender, Alice, and a recipient, Bob, connected by means of a communication channel of some sort.

Chapter 14 on security management assumes familiarity with the content of Chapter 13 on risk assessment. You will find a synopsis of the problems dealt with in each chapter below. The index in the back of the book can be used to find all chapters that refer to a key word or topic. 2 Security Electronics We often make a distinction between the hardware and the software of a computing device.
