Why we need to develop a web site?

A web development takes into an account for many security considerations, such as data entry error, checking through forms, filtering output and encryption. Scripts can be used to exploit websites by granting unauthorized access to malicious users that try to collect information such as email addresses, passwords and protected content like credit card numbers. Stringent testing of web applications before public release in encouraged preventing such exploits from occurring.

Keeping a web server safe from intrusion is often called Server Port Hardening. Many technologies introduced into play to keep information on the internet safe when it is transmitted from one location to another. Many developers often employ different forms of encryption as Secure Socket Layer, when transmitting and storing sensitive information. A basic understanding of information technology security concerns is often part of a web developer’s knowledge.

Some new security holes are found in web applications even after testing and launch, security patch updates are frequent for widely used applications. Organization that build websites typically have a test site where a new website is tested to make sure everything works correctly before it goes live on the World Wide Web. After a staging site has been tested and found to be working properly it can be launched to the public. A running production site and staging server allows developers to make changes to their site and test changes before applying them in real time.
