In the past 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 and online shopping carts, inquiry forms, or login fields.
Because these applications are Internet-facing and can be accessed from anywhere in the world, they are at risk for attacks on security that exploit weaknesses in the application’s infrastructure. SQL injection attacks which exploit weaknesses within databases, could compromise databases that hold sensitive data. Attackers may also use an advantage gained by breaching a Web application to discover and access other vulnerable systems on 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 an infected code in the victim’s browser. This enables attackers to access to confidential information or redirect users to websites that are phishing. Web forums, message boards and blogs are prone to XSS attacks.
Distributed denial of service attacks (DDoS) are when hackers band together to bombard a site with more requests than it can handle. This can cause a website to slow or even shut down completely. This interferes with the ability of the website to process requests, making it inaccessible to everyone. This is the reason DDoS attacks are particularly devastating for small businesses that rely on their websites for operations for their business, such as local bakeries or restaurants.
