The 8G Firewall is a carefully crafted set of security rules for Apache and Nginx servers. It can be applied via your site’s public root file, or added via server configuration. Once added, 8G provides powerful server-level protection against a wide range of malicious requests, bad bots, automated attacks, spam, and many other types of threats and nonsense. It’s a lightweight (only 17KB) strong firewall that improves site security and peace of mind..htaccess,
Two unwritten laws of the Web: 1) Nothing is 100% secure, and 2) All websites are under pretty much 24/7 constant attack. Whether it’s just nuisance traffic like spam, or serious in-your-face DDoS attack, now is the time to strengthen site security and lock things down. nG helps with this by protecting your site against many types of bad requests and attacks. It gives your site a super strong layer of protection at the server level. So bad requests are blocked without having to load up PHP, MySQL, and everything else. Strong security without sacrificing performance.
I’ve seen many times sites just getting hammered with bad traffic.. then you add nG Firewall and watch the noise drop to zero. You free up all those server resources for the good traffic.
So what’s the downside? Well, same as with any firewall, potential false positives. Fortunately, nG comprises over a decade of research, testing, and development. It builds on the best features of previous nG Firewalls. Ultimately, the goal for nG Firewall is zero false positives.
Bottom line: nG is an easy-to-use, cost-effective way to secure your site against malicious HTTP activity. It helps to protect against evil exploits, ill requests, and other nefarious garbage, such as XSS attacks, code injections, cache poisoning, response splitting, dual-header exploits, and much more.
How It Works
The nG Firewall is a powerful, well-optimized set of mod_rewrite rules that checks all URI requests against a set of carefully constructed Apache/.htaccess or Nginx directives and regular expressions. This happens quietly behind the scenes at the server level, which is optimal for performance because it avoids the need to load up PHP and MySQL just to block a bad request. This is one reason why securing at the server level is better than using a plugin or other PHP script.
nG improves performance by freeing up server resources.
For Apache servers, nG Firewall is easy to implement. Just add the code to your site’s public root .htaccess file. Then sit back and relax while nG Firewall works its magic. That’s the beauty of it: there is no configuration required. Security via simplicity: add the code and done. For more details, check out the Deployment section below.
