What is Internet Security?
Internet Security Program
Three basic concepts in Internet security program are confidentiality, integrity and availability. When an unauthorized person reads or copies information, it results in a loss of confidentiality. When the information is modified in an irregular manner, it results in loss of integrity. When the information is erased or becomes inaccessible, it results in loss of availability.
Authentication and authorization are the processes of Internet security system by which organizations make information available to those who need it and who can be trusted with it. When the means of authentication cannot be refuted later, it is called nonrepudiation.
