DotDefender - a Web Application Firewall

By Kevin Abrahams


Dotdefender is one of the many web application firewalls that protect your managed servers. It offers safe and secured internet access for your web applications and computer system alike. If you are looking for trusted firewalls you might as well try dotdefender for it is one of the web application firewalls that could be trusted on the internet. A firewall is one of the important structures in the internet for a managed server to have. It helps you to avoid any damage on your system as well as on your web applications. Thus put in mind that a firewall is just a prevention program not something that eliminates online threats, you need an anti-virus for that purpose.

With the use of the WAF, you can now manage servers and configure the way you want it in order to increase the security of your system. You can easily configure the application to allow all kinds of requests and block those that come from malicious sources. You may also use it the other way round by blocking all traffic except that it is known as good for your system. One can also use it in several modes that include transparent proxy, reverse proxy, network monitor, and layer two bridges. This can also have added features such as catching pages that you often requested as SSL acceleration and load balancing.

Although web application firewall is very useful tool in increasing the security of your website and managed servers, this technology is something that will require you to test and configure right before its implementation. Right after the implementation, you also need to regularly fine tune the system to make sure that it is working accordingly. Another warning is that you need to remember that Web Application Firewall is an incomplete suite of security tool and therefore you need to use this technology together with other tools and as a part of a much wider security policy.

A managed server would always be prone to viruses and worms for it would be visited by various users that maybe infected. Firewalls such as dotdefender could prevent this from occurring so better be safe and sure than to be prone and unsecured. Investing in prevention can save many resources that would be needed for repair and they can be channeled towards other projects.

There are many reasons why there is a rise in security vulnerability. It maybe because the security input validation is very poor and the session is not secure. If the system is not properly configured there is also risk to your managed servers. It might also be a result of many flaws within the web managed servers or in your chosen operating system. It is important to remember that hackers are getting more and more creative in finding ways on how to hack different managed servers so the use of web application firewalls is helpful.
