In the last decade, millions have used the Web to communicate and conduct business with their customers. This includes web-based applications that store and collect data. This includes information about customers provided through content management systems, online shopping carts, inquiry forms or login fields.
Because these applications are Internet-facing and often accessed from anywhere in the world they are at risk for attacks that exploit weaknesses in the application or its infrastructure. SQL injection attacks which exploit weaknesses in databases, can compromise databases that contain sensitive data. Attackers could use the leverage they gain from compromising your Web application to identify other systems that are more vulnerable in your network.
Other popular Web attacks include Cross Site Scripting attacks (XSS) which exploit flaws in the web server to inject malicious code into web pages, and it executes as a virus-infected script within the victim’s browser. This allows attackers steal confidential information or redirect the user to sites that offer phishing. Web forums, message boards, and blogs are particularly vulnerable to XSS attacks.
Distributed attacks on service (DDoS) comprise hackers banding together to pummel a website with more requests than it can handle. This can cause a website’s performance to drop or even cease to function completely. This can affect the ability to handle requests, and makes it unusable to everyone. This is why DDoS attacks can be especially damaging for small businesses that rely on their websites for operations in local establishments, like bakeries or restaurants.
