Users of computer systems already have the data and information of value for him. Protecting this data from the parties has no right is important for the operating system. This is called the security (security). An operating system has some aspects of security. Aspects of this deal, especially with the loss of data. Computer systems and data in the aspect of the threat risk (threats), aspects of it (intruders), and natural aspects.
Aspects of the threat, the general system face the threat of opening the computer data secrecy, data-conversion data by the person who does not have the right, also with the system pelumpuhan Denial of Service (DoS). Aspects of it, at this time many people trying to enter into an operating system with a variety of purposes. There is simply trying to penetrate the operating system (hacking), who have tried to take advantage of the action penjebolah (cracking). Disusupi not only by humans, the operating system is also facing threats from the security program it, which is called malicious programs or malware. Malicious programs that is to infiltrate in the operating system and have goals such as taking personal data, the computer takes over, and often destructive aims. Including the category is a malicious virus, Keylogger, worm, trojan, and spyware, Trapdoor, Logic bomb bacteria.
Finally, the operating system and data in it is threatened from things non-technical, that is from the natural. Operating system due to the threat of natural disasters (floods, mud, heat, earthquake, etc.), damage to hardware or software, even omission of the users. The development of the internet at this time to bring the consequences of the increased risk of operating system security. Therefore, the operating system must have the resilience of the security. For most developers operating system at this time, security is one of the main problems.
