In the last decade, millions of businesses and organizations have taken to the Web as a cost-effective way to communicate with customers and conduct business. This includes web applications that collect and store information. This includes customer information provided through content management systems, online shopping carts, inquiry forms or login fields.
Because these applications are Internet-facing and frequently accessible from anywhere in the world They are susceptible to attacks on security that exploit weaknesses in the application’s infrastructure. For instance, SQL injection attacks (which exploit weaknesses in the database) can result in compromised databases that hold sensitive information. Attackers may also use the security of an Web application to discover and gain access to other, more vulnerable systems on your network.
Other typical Web attacks 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 sensitive information or send users to phishing sites. Web forums, message boards and blogs are particularly susceptible to XSS attacks.
Distributed attacks on service (DDoS) are when hackers band together to pummel a website with more requests than it is able to handle. This can cause a website’s performance to suffer or even stop functioning completely. This can affect the ability to handle requests, and renders it unusable to everyone. This is why DDoS attacks can be particularly damaging for small businesses that rely on their websites to operate in local establishments, like bakeries or restaurants.
