In the past decade, a lot of people have utilized the Web to communicate and conduct business with their customers. This includes the use of web applications that store and collect data such as customer data submitted through content management systems, shopping carts inquiry or submit forms and login fields.

They are usually accessed via the Internet and can be hacked in order to exploit weaknesses within the application or its supporting infrastructure. For instance, SQL injection attacks (which exploit weaknesses in the database) could result in compromised databases that contain sensitive data. Attackers can leverage the foothold they gain by breaching your Web application to find other systems that are more vulnerable within your network.

Other commonly used Web attack types include Cross Site Scripting attacks (XSS) that exploit vulnerabilities in the web server to inject malicious code into web pages, and which executes as a virus-infected script within the victim’s browser. This allows attackers to gain access to private information or redirect users to phishing sites. XSS attacks are most prevalent on blogs, message boards and online forums.

Hackers collaborate to overwhelm websites by sending more requests than the site can handle. This can cause a website to lag or even stop functioning completely. This can affect the ability to handle requests, making it unusable to everyone. DDoS attacks can be devastating to small businesses, like local bakeries or restaurants that rely on their website for operations.
