Course

Security


     Security is the condition of being protected against danger or loss. In the general sense, security is a concept similar to safety. The nuance between the two is an added emphasis on being protected from dangers that originates from outside. Individuals or actions that encroach upon the condition of protection are responsible for the breach of security. The word "security" in general usage is synonymous with "safety", but as a technical term "security" means that something not only is secure but that it has been secured. In telecommunications, the term security has the following meanings:


-           A condition that results from the establishment and maintenance of protective measures that ensure a state of inviolability from hostile acts or influences.


Security has to be compared with other related concepts: Safety, continuity, reliability. The key difference between security and reliability is that security must take into account the actions of malicious agents attempting to cause destruction.


Perceived security compared to real security


It is very often true that people's  perception of security is not directly related to actual security. For example, a fear of flying is much more common than a fear of driving; however, driving is generally a much more dangerous form of transport.
