Web vulnerability analysis and implementation

Data security on the internet is synonymous with a website and a computer network that connects to one another. In the context of computer networks, any existing data on a computer that is connected to another computer, is unsafe, so need to do some way to secure the data so that cannot be accessed by another computer. Each website is created using a series of codes to be able to display data that is public and accessible or accessible to everyone. However, usually on the server computer where the website is stored, there are also data that are confidential or private, so it is not allowed to be accessed by the public. This research is conducted to analyze various techniques and ways of attack that usually done on the internet website, in order to implement various ways of handling so that the existing website can be more secure against the attack so that the data contained in the server. The results have been obtained that is known some weaknesses and attacks that occur on a website. This research used htaccess technique and website script for security improvement. But, the improvements that have been done still cannot guarantee the website 100% safe, it is because that in the world of data security in addition to the web and server side is fixed, must also be viewed from the network security.
