Website Firewall – Protect Your CMS
A lot of Internet users in the matter of website security are limited to installing an antivirus. But in addition to viruses, which in recent times are not very common, the Internet is full of any infection, and striving to settle on your website.
Judge for yourself: trojans, worms, hacking tools (backdoors, exploit, Hack Tool, constructor, bad-joke), and of course the hackers themselves (referring to direct attacks on the computer, such as DDos). Have you heard about botnets, about illegal proxy servers? After all, it is your website that can be one of the zombies sending spam, or serve as a proxy for a hacker.
How Firewall Works
To detect and prevent attacks on web applications, the Website Firewall checks all requests to your web server and the corresponding responses from the server to match its set of rules. If the test is completed, the request is sent to the site to receive the content. If the test fails, the specified actions are performed.
The number of companies that use web technologies to increase productivity and attract new customers is growing every year. Undoubtedly, Internet services carry a lot of advantages, but there is a downside to the coin - with the growing number of applications, the number of cyber threats also increases. For example, with the help of XSS attacks, a hacker can redirect user requests to malicious Web pages, and using SQL injections, extract various confidential information from the site's databases. Website Firewall can provide comprehensive protection for Web applications against known and unknown threats.
What Types Of Attacks Can Firewall Prevent
At its core, Website Firewalls are a network filter between the internal (corporate) and the external network (that is, the Internet environment). The first firewalls were only able to block suspicious network packets at the network and link layers based on the source and destination IP address, the fragmentation flag, and port numbers. More advanced systems are able to analyze the contents of network packets and compare it with the signatures of known attacks. In addition, these systems detect and block deviations in the application layer protocols. However, today more than 80% of attacks exploit application vulnerabilities, not network architectures. Therefore, a simple system of protection is ineffective against modern cyber threats.
In addition, today there are a huge number of web applications (each of which potentially have some vulnerabilities), that is, the total number of vulnerabilities is much greater than the number of signatures in the bases of modern IPS-systems. According to experts, penetration through web applications has recently become the main vector of attacks on corporate networks, and traditional security systems, such as a firewall and an anti-virus system, did not prevent such attacks.
For reliable protection, you need a fundamentally different approach: with a deep analysis of the contents of packages and a good knowledge of the structure of Web applications, including URL parameters, cookies, data entry forms, etc. Such conditions are met by the Website Firewall - a firewall for applications that transfer data over HTTP and HTTPS.
To detect attacks, Website Firewall applies both signature and behavioral approaches. The second method is also very important, because for attacks on web applications, cybercriminals can apply zero-day vulnerabilities, which nullifies the effectiveness of signature analysis. At the same time, Website Firewall is able to determine the model of normal operation of the application based on the analysis of network traffic and system logs and its basis to detect deviations in the behavior of the software system. In particular, Website Firewall can detect attacks using automatic means. A classic firewall generates huge amounts of false positives for all kinds of suspicious events. To detect the threat level, these notifications must be parsed manually. At the same time, Website Firewall is able to analyze thousands of events and build a chain of attack development - from the first stage to the last.
