Software Security

Security is the main issue over all kinds of software products.For maintaining the security,its piracy is very important.Its really a hottest topic in computer circles.Duplication of the software product and tracking copy of the software may cause a huge loss for the software developer.This may leads to a problem.Today,some of the companies can develop the softwares by means of application code with hacker proof modification techniques.one way to protect software is by means of obfuscation code.This code is very hard to understand.c,c++ and perl languages are the examples for obfuscation code.Shrouded code is also been used. It is very difficult to read and understand.Its not like machine code.This kind of coding is used in in-house application development.

Software Development Cycle

Software Development Cycle is a process of developing a software through various stages.This includes 6 stages.They are Analysis,Design,Coding,Testing,Deployment,Maintenance.Analysis stage involves what are all the requirements needed for implementing the software.Here developer must satisfy the client's requirements.This stage is the initial stage for designing process.Designing the software is the main task in Software development because design stage represents the pictorial representation of software.It finalise the end product quality of a software.The third stage is coding.Here software programmer can start their programming by using specific languages.Languages such as c,c++,java,j2ee,Html,vc++,vb,and so on.The next stage is Testing phase.In this stage,developer can rectify the errors occurred during coding stage.The code is to be hand over to the client after the testing process completes.this stage is called Deployment stage.And the updations of software,error report by the client should be done in Maintenance stage.
