Abstract: Today’s technology is heavily dependent on web applications. Web applications are being accepted by users at a very rapid pace. These have made our work efficient. These include webmail, online retail sale, online gaming, wikis, departure and arrival of trains and flights and list is very long. These are developed in different languages like PHP, Python, C#, ASP.NET and many more by using scripts such as HTML and JavaScript. Attackers develop tools and techniques to exploit web applications and legitimate websites. This has led to rise of web application security; which can be broadly classified into Declarative Security and Program Security. The most common attacks on the applications are by SQL Injection and XSS which give access to unauthorized users who totally damage or destroy the system. This paper presents a detailed literature description and analysis on Web Application Security, examples of attacks and steps to mitigate the vulnerabilities.
Abstract: Internet security attack could endanger the privacy of
World Wide Web users and the integrity of their data. The attack can
be carried out on today's most secure systems- browsers, including
Netscape Navigator and Microsoft Internet Explorer. There are too
many types, methods and mechanisms of attack where new attack
techniques and exploits are constantly being developed and
discovered. In this paper, various types of internet security attack
mechanisms are explored and it is pointed out that when different
types of attacks are combined together, network security can suffer
disastrous consequences.
