Computer Security or IT Security, intuitively, is the general concept of protecting computers against any non-intended use. As Morrie Gasser defines it, “The protection of computer systems from the theft or damage to the hardware, software or the information on them, as well as from disruption or misdirection of the services they provide”. This term is so general that it includes such a myriad of different types of security to protect and involve the following…
Cloud security, which involves data held in server rooms not under your personal management.
Malware protection, which eliminates software or any other type of malicious programs that try to attack a computer.
Phishing, which is primarily a malicious email sent in order to retrieve information illegally.
Encryption, which encodes messages or information that is sent in order for that information to be only readable by the intended user.
And etc.Relation to Computer Science:
IT security’s relationship to computer science should be apparent in that it directly deals with protecting computers, hardware, and software, all which operate using CS. The difficulty with security is that it is preventing computer science programs with computer science programs, which both usually have either errors or entry ways to access. This promises that both malware and security are not always efficient or 100% protective. However, security is absolutely essential for privacy relevant to any information or program that contains high importance.
