Operating System Security
Abstract
Information systems are now becoming the social infrastructure so it is necessary to improve the security level because of privacy and data theft. One of the important issues which have to concern in the security of cyberspace is the security of operating system. This paper helps us to know about the security of most commercial Operating system like UNIX and
Microsoft windows which are widely using in whole world. Introduction
Computer system from network servers, desktops to laptops and hand held devices, they specially use a piece of software which know as operating system and execute on hardware that able to allocate the basic resources of system and supervises the execution of all applications within operating system. OS manages all types of resources management and security aspects.
Microsoft window, UNIX and Linux are example of operating system.
The security of an operating system of computer system will have fundamental impact to overall security of a computer system and also the application which are running in system. If we don’t proper control the execution of individual applications in an operating system may attack, from one application to other applications.
This level of protection provides safeguard of different applications in a multi-tasking,
Time sharing. No mechanisms are supported by operating system in the class that able to enforce policies to secure an individual applications .As we know that use of internet is growing widely so security of applications now become basic goal for millions of consumers who are turning their business to the public world of cyberspace. Efforts are going to made to achieve total security of a system and applications.
To raise the security of operating system, MAC is necessary. A typical MAC architecture needs the ability to enforce an administratively set security policy over all subjects and objects which are going to used like
