Security threats over web applications

The web has become an integral part our work and life in this era of seamless computing,but hackers follow numerous trends to create serious threats to web applications. The vertical shift towards web based threats is changing the way IT security needs to be deployed and effectively monitored.

Web and HTTP protocol are the platform for web applications, so it implies more security challenges than desktop applications, which are far less accessible and typically have their own unique file formats and scripts.

The following are the recent six modes of threat to web applications,

Cross-site scripting is the method of adding lines of java script into web pages, if not secured; malicious code can be submitted to the search bar, like a user comment post on a social networking site.

With Session Hijacking, a “session“is assigned to each unique user  when they are logged in to a website .Session hijackers pass the information between the user and server by jumping into session of another user.

Through Parameter Manipulation, a website passes information from one web page to the other through URL parameters, for example if you use a search engine, it will pass the terms to the results page through the URL. This can be used by the hacker to manipulate these parameters in a mischievous way.

A small amount of space allotted to store data is termed as Buffer overflow. The extra data will overwrite data in other areas if the buffer is over loaded. The information is explored by the hacking community to overfill a buffer, and then overwrite the other data with their own malignant code.

An effective but simple method is Denial of Service. They work by flooding a website with numerous request for information, which slows down functioning of a website or crashing the website completely.

SQL Injection works as same as cross-site scripting, but in this scenario harmful SQL statements are inserted in to a website. These statements change the database in certain manner to access vital data and deleting it entirely, causing mayhem to the website.

So it’s better to put your security protocol at first place to avoid these threats and guard against potential hacker.
