Safer Interactions with the Internet through a Web Application Firewall

The internet represents a revolutionary step forward in the way data is stored and accessed, and in the way business is done. Most enterprises make use of user-friendly websites or web applications which allow their users to interact and transact.

But allowing users to seamlessly interact with your server and database presents some problems too. Primary among them is that it is difficult to differentiate between genuine users and hackers.

This is where a Web Application Firewall (WAF) comes in. A WAF allows you to protect your servers from online attacks on the internet.

For instance, there may be several nodes or entry points into your network, which security threats from the internet can penetrate. A robust security solution should ensure that these individual layers or nodes stay uniformly protected. Even if one of the layers is compromised, the impact of the breach could be severe. But micromanaging the security of every node in your network is time-consuming and invariably increases the latency of system operations.

A Web Application Firewall (WAF) can help you ensure the security of your network by monitoring and controlling all the HTTP conversations that your systems have with the internet.

What is a WAF and how does it work?

A Web Application Firewall comprises a set of instructions or protocols which have to be adhered to when using web-based applications. It protects your network and servers from websites whose scripts could be infected with malicious code intended to breach your security and access your data.

While using web applications, your searches and actions are considered client requests. These requests are processed by proxy servers which are kept in place to protect the client system. The proxy server receives the correct response from remote servers and transmits the data back to you.

A WAF acts a reverse proxy which protects your servers from attacks. It is an intermediary layer between the client and server, which makes it seem like the response is forwarded by an actual proxy server.

Website Filtering using WAF

A robust WAF comes with advanced DNS filtering features which examine every request from your network and send back only relevant and secure results. In addition to providing a layer of security to your servers and filtering websites based on its security loops, an effective web filtering solution should also simply allow you to blacklist websites because they could be irrelevant to the work done by your employees. Unmoderated internet access can have serious repercussions in terms of productivity drain.
