Web application is used web server controlled environment such as already finish web templates, or coded language such as HTML, PHP and etc.(1. Paul Stanley 2013).

Web Apps has developed applications and advantages are very useful. Web apps can be accessed 24/7 from any place work, public place, or from any place in the world. To access web apps smart phones can be used or computers, the only requirement to access web app is to have connectivity to the Internet server. Another advantage of is that it can’t be implement on local device same time that they run on the web servers, it means that it saves lots of disc space capacity and time to do application installation process. Expenses are not applicable. Compatibility is one of the web application benefits as it that can work on different browser platforms; user can use different browsers to connect to web application (1.Paul Stanley 2013).

There are two main Scripting Languages: Server side and Client side Scripting languages. Web pages work using server and client techniques. These Server and Client scripting languages are used together but this scripting languages are different. Server – side scripting language is used to complete the searching application; Server side scripting language using ASP.net SQL and PHP, the results generate and give result for the user. Client – side scripting languages, such as top down menu. In this case JavaScript languages changes how the web apps is displayed and run the code (2. Lynn Jurewicz and Todd Cutler 2003).

Security use in web application

Administrator must assure that the security for the web page is at its highest level. There is damaging of data and main systems, phishing, identity theft, monitoring unauthorized access and much more. To protect the web application from hack attacks, Trojans, viruses and Internet worms there is some of security tools. The main one is the firewall your web application server, which build the protection barrier around computer. It means protects your web application server from outside network unauthorized programs access to the data. Firewall can open or close some of the ports, which used by computers to pass or restrict the data. It is highly recommended for web server to close all the ports which are not in use. Firewall must be running at all times. Nowadays there is plenty of antivirus software that can be installed on all devices such as computers, servers or in data base. Anti – virus software must be often updated as it helps to recognize virus in the network. Another way of security is “SSL Secure Socket Layer” which provides secured communication on the Internet given that endpoint authentication. Is more used to protect credit cards details, social security numbers. And of course is manual security policy, use long password with numbers and symbols, especially for administrators connect to web server, who will have rights to edit, delete, P.S password can’t be similar to user name or any visible information (3.Microsoft 2005).
