In the past decade, millions of people have used the Web to communicate and conduct business with their customers. This includes web-based applications that collect and store data. This includes information about customers provided through content management systems and online shopping carts, inquiry forms, or login fields.

Since these applications are online-based and can be accessed from anywhere in the world They are susceptible to hacking attempts to exploit weaknesses in the application or its supporting infrastructure. SQL injection attacks, which exploit weaknesses in databases, can compromise databases that contain sensitive data. Attackers can use the foothold they gain from compromising your Web application to locate other, more vulnerable systems 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 it executes as an infected program in the victim's browser. This allows attackers to gain access to private information or redirect users to phishing websites. XSS attacks are most common on message boards, blogs and web forums.

Distributed denial of service attacks (DDoS) are when hackers band together to bombard a site with more requests than it is able to handle. This can cause the page to slow down or shut down altogether in a way that hinders the ability of the site to process requests, making it unusable for all users. DDoS attacks can be devastating for small businesses, like local bakeries or restaurants that depend on their websites for operations.
