Your Guide to the 3 Layers of Website Protection

Of course, it’s difficult to talk about completeness when it comes to information security. Even the professionals need serious resources for comprehensive protection, from architecture to operation, and even then, perfection still isn’t guaranteed. There are no standard web security measures, so every individual builds security depending on their own unique situation. Web security solutions need to fit each company’s IT system. This begins with understanding how a company’s IT system is structured.

The Three Layers of an IT System: Network, System, Application

Generally, an IT system consists of networks, systems, and applications. Each of these three layers need their own unique level of protection. The networks layer at the bottom of this stack deals with data transfer, while the systems layer (what we know as operating systems such as Windows or Linux) works as a platform that enables the applications layer to operate. The applications layer itself offer protocols and services with many features. Many kinds of server systems are just like this structure, so securing the server means all these three layers are safe.

Don’t Overlook Web Application Security

Despite the importance of web application security, most companies spend 10 percent on web application security compared to network security. The reason is simple: companies don’t know what to do about web application security. The application layer is technically more complicated and the kinds of applications also vary.

Most security professionals find it difficult to set up a security policy and apply security measures. What we think of as the ‘web’ actually consists of applications. Websites and mobile apps are all applications, and attacks on these also take advantage of the vulnerabilities of applications.

Web attacks such as SQL injection or XSS also target the vulnerabilities of website applications. Malicious code called a ‘web shell’ also consists of a type of web application. The Open Web Application Security Project (OWASP), famous in the web security industry, named 10 web vulnerabilities, all of which are web application attacks.

More than 90% of web attacks target web applications. A web application firewall (WAF) is what protects your website from unwanted visitors. Its role is like a fence. It monitors traffic, detects web attacks and protects your website. What’s important is that it prevents vulnerabilities from being exposed. From the outside shell, it limits access from malicious traffic. Also, it hinders malicious code from being uploaded to your web server.
