Over the past decade, millions of businesses and organizations have accepted the Web as a cheap way to communicate with customers and conduct business. This includes the use of web applications that store and collect data such as customer information that is 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 to exploit vulnerabilities within the application, or in its infrastructure. For example, SQL injection attacks (which exploit weaknesses in the database) could result in compromised databases that contain sensitive information. Attackers can use the foothold they gain by compromising your Web application to find other, more vulnerable systems within your network.

Cross Site Scripting (XSS) is another well-known Web attack type. It exploits weaknesses in web servers to inject malicious code into web pages. The script then executes in the victim’s web browser. This allows attackers to access confidential information or redirect users to phishing websites. Web forums, message boards and blogs are especially vulnerable to XSS attacks.

Hackers collaborate to overwhelm websites by sending more requests than the site can handle. This can cause the page to lag or even shut down completely in a way that hinders its ability to process requests, rendering it unusable for everyone. This is why DDoS attacks are especially devastating for small businesses that depend on their websites for operations, such as local restaurants or bakeries.
