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

Social Security The purpose of this paper is to analyze social security so as to show the reader what makes it beneficial to us today. . Throughout my life the words social and security have meant little more to me than the representation of a small blue card in my wallet‚ a consistent and increasingly significant deduction of funds from my weekly pay-check‚ and a vague academically-instilled recollection of the potential for long-term future benefit. In fact‚ it was not until I researched

Some Questions on laws related to Software Engineering Ques1: Describe each law in your own words. Illustrate with a practical example. Ans1: Glass’ Law: “Requirement deficiencies are the prime source of project failures” Lack of requirements is the major root cause of unsuccessful projects. The major reason of project failure is lack of requirements. Requirements are usually defined in first phase of project development and if not defined properly may cause problems in further stages and ultimately

Network security concepts Network security starts with authenticating‚ commonly with a username and a password. Since this requires just one detail authenticating the user name —i.e. the password— this is sometimes termed one-factor authentication. With two-factor authentication‚ something the user ’has’ is also used (e.g. a security token or ’dongle’‚ an ATM card‚ or a mobile phone); and with three-factor authentication‚ something the user ’is’ is also used (e.g. a fingerprint or retinal scan)
