Maintaining a good online presence is quite a tedious task – one has to deal with a continuously changing landscape while doing so. New technologies take the place of old ones, protocols get renewed and there are constant changes in the patterns of online traffic. Earlier, most of the traffic on the Internet was managed by FTP (File Transfer Protocol). The same is taken care of by HTTP (Hypertext Transfer Protocol) today. This protocol is so efficient that many people are still under the impression that the Internet and World Wide Web are the same while the latter is just a subset of the former.
Web applications today are much more innovative and at the same time vulnerable to security threats. As a result, web application security testing has become a necessary routine for businesses which use these applications to interact with their customers and clients in a better way.
The following sections will explain some facts about web application security.
Advent of New Technologies
No matter how advanced the current technology is, users always crave for better options – a simple example for this fact is the demand for responsive websites which can run on several devices such as tablets, smartphones, laptops and personal computers. Advancement in technology has improved not only web applications but also the techniques to hack into them. Hackers today have figured out numerous ways to break through network firewalls guarding web applications. For instance, a simple protocol is capable of transferring text, images as well as complicated AJAX scripts having sensitive information. Companies that build web applications thus need to stay ahead of attackers.
Web Apps Are the New Battlefields
The internet today is a widely used medium of communication – this has caused an increase in the number of attacks on web applications. As a result, companies that deploy these applications are adopting a multitude of defense strategies. Unfortunately, these strategies are not good enough to counteract the attempts of hackers. They can use a distributed network of infected proxies and zombies to initiate a series of attacks which can allow them to exploit thousands of web browsers for extracting confidential information. A common website or web application is targeted by crawlers and worms about 200 times on an average in a day, in an attempt to look for security flaws. A website security audit becomes necessary in such a scenario.
