3 development; everything was done on ad hoc basis. This ad hoc approach led to the ‘software crisis’. Over the last few decades there has been a tremendous growth in information technology and its impact on everyday life. Complex software systems have become critical to the operation of many systems in areas such as banking, communications, manufacturing, power generation, and transportation. Progress in computer science and accumulated experience with industrial production of software have led to the emergence of software engineering as a separate discipline. The software engineering discipline has been defined as "the application of systematic, disciplined, quantifiable approaches to the development, operation, and maintenance of software." that is, the application of engineering to software . The computer science discipline concerns with developing large applications. Software engineering covers not only the technical aspects of building software systems, but also management issues, such as directing programming teams, scheduling, and budgeting.

are more powerful than before,the virus writers are getting a lot smarter with newer and creative ways to attack network systems.Let's first examine some common virus types: Basic Virus-a piece of software code that is developed to attack computers and network systems via email or Internet connections.It quickly replicates itself and gradually attaches to files, programs or the hard drive. Trojan Horses-This is a program that doesn't replicate when entering a system but can be effectively used to open 'back doors.'Trojan Horses allow hackers to take control over a particular system or to steal very important data. Worm-this type of virus is able to spread itself automatically over the network from one computer to the next.During a worm attack,users'computers get infected without even having to click open email attachment or any program,etc. Since it is very difficult to avoid the virus,your best defense is a powerful antivirus program. In order to fight with such viruses,the software vendors should focus on making their products more robust.This may ask for a trade-off between user-friendliness and security.In specific cases it may require line-by-line inspection,code retooling and even systems automation to defend the installed programs.
