//**The ITGS Guide Definition:**// Security refers to the protection of hardware, software, machines and networks from unauthorized access, alternation or destruction. Security measures include strict access to machines and networks and encryption of information. The degree security of information systems determines society's confidence in the information contained in systems. //dictionary definition// Freedom from risk or danger; safety.

In IT security is used all the time because if not all the information that is stored on your computer could be accessed by anyone who goes onto your computer. The first stage of security and probably the most simple is passwords, these allow you to keep information, that you want to be, to be kept secret. The UAE is a very good example of security in IT because, all the internet in dubai and across the UAE is protected so the people in the country cannot access certain sites such as pornographic images and some sites that may have articles incriminating the royal family. This is because it is an islamic country and so things like pornography are banned. Here is an article on security [|article for security]

//**Examples of breaches in security:**// //Viruses// This breach of security is very common in IT, A virus for example is simply a program that can duplicate itself and infect your computer, so it can delete files or make them inaccessible, it piggy backs onto other programs for example if it attached to microsoft word, every time that word runs so does the virus and this gives it chance to duplicate. Some viruses can be very simple but can have devistaing effect to not only your computer but to large companys such as the [|melissa virus] in 1999 which was so powerful that it made such large companys such as microsoft, to shut down their email systems completely until the virus was intercepted. //Hacker// The term "hacker" originally meant a very gifted programmer. In recent years though, with easier access to multiple systems, it now has negative implications.) Hacking is something where someone basically breaks into a computer and can bypass security sytems that others have put on thier computer or systems or an unortherised access to a computer resources. Hackers break into computers, usually by gaining access to the adminastrive controls.

//Protection// There are programs that you pay for to protect your computer from viruses shuch as [|Norton anti virus] this will protect your home computer or laptop from internet viruses, but for very large companies this sometimes wont work.
