I’ve been working on developing the 8G Firewall. Digging through log files and crunching the data, the big new trend I’m noticing is heavy scanning for easy targets, low hanging fruit. Bad actors are looking for any little hidden files stashed on your server. Mostly PHP files, also ZIP and RAR files, and other file formats commonly used for compressing and archiving content. Basically, anything that might contain useful information (like login credentials, database backups, email addresses, etc.). Also, 99% […] Continue reading »
BBQ Firewall is built to be powerful, lightweight, fast and flexible. It’s code base is kept super lean, leaving extra functionality out of core while supporting new features via simple addons. For example, this tutorial shows how to use an addon to display the total number of blocked HTTP requests on the plugin settings page. This can help you get a basic idea of the plugin’s effectiveness. Continue reading »
This tutorial is for users of my nG Firewall, version 8G or better. It explains how to enable logging for all blocked requests. This is useful for testing, debugging, and keeping an eye on things. Takes only a few minutes to set up, and of course it’s all open source and 100% free for everyone :) Continue reading »
After more than a year of beta testing, 8G Firewall is ready for use on production sites. So you can benefit from the powerful protection provided by the latest evolution of the nG Firewall (aka nG Blacklist). The 8G Firewall offers lightweight, server-level protection against a wide range of malicious requests, bad bots, automated attacks, spam, and many other types of threats and nonsense. 8G is a lightweight (only 17KB) strong firewall that provides site security and peace of mind. […] Continue reading »
The nG Firewall is a carefully crafted set of security rules for Apache and Nginx servers. nG may be applied via your site’s public root .htaccess file, or added via server configuration file. 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 yet super strong firewall that improves site security and peace of mind. Continue reading »
Recently WordPress sites have been getting hammered with random-string comment spam. The attackers are clever, using random text strings for every vector except the payload, which usually is the URL used for the comment’s Name link. But for these weird comment spams, the apparent payload is the email address. It’s the only part of the comment that’s not made up of random gibberish. Continue reading »
There are many free (and commercial) uptime monitoring services that will alert you if your server goes offline. These services are popular because it’s mission critical to know when your sites are down. The sooner you know about it, the sooner you can scramble to get everything back online. I’ve tried other scripts and services but nothing that met my specific needs: simple, secure, lightweight and blazing fast. So decided roll my own DIY server status monitor and share it […] Continue reading »
In case you hadn’t noticed, I’m on another one of my posting sprees. Going through the past year’s worth of half-written drafts and collected code snippets, and sharing anything that might be useful or interesting. Here is a bit of .htaccess that brings together several redirection techniques into a singular plug-&-play code snippet. Continue reading »
I’ve written many articles about how to redirect requests. Even so, I still get questions about how to set up a simple HTTP request router. As in you want to redirect or route all requests to some file or location. This is useful for building CMSs and scripts that handle traffic. For example, WordPress uses a simple request router when permalinks are enabled. For this tutorial, we’ll set this up using Apache/.htaccess and PHP. Continue reading »
I have thought a lot about making an nG WordPress plugin. The problem is that writing to .htaccess via PHP/plugin is risky with lots of ways to fail and make users confused and angry. And nobody wants that, in fact just the opposite: my plugins strive to give users the most awesome experience possible. Continue reading »
For years, I’ve not used ModSecurity for any of my own sites. Way back when I first tried ModSecurity, there were just too many false positives, so I stayed away from it, opting instead to develop my own fast Apache/.htaccess firewall. But my web host now is telling me that ModSecurity is required on all of their managed VPS plans. Continue reading »
![[ Protect WordPress Media Files ]](https://perishablepress.com/wp/wp-content/images/2019/wordpress-media-library.jpg)
This is an experimental technique that I am playing with. It’s the simplest possible way that I could think of to protect all files in the WordPress Media Library using only Apache/.htaccess. I’ve been testing the code on an image-heavy site and so far there are no issues. So I want to put the code out there for others to test and hopefully provide feedback if anything less than perfect. It’s a super simple method that prevents media files from […] Continue reading »
There are numerous ways to redirect requests using Apache’s mod_rewrite and mod_alias. This concise, friendly tutorial explains different ways to redirect a range of IP addresses, either IPv4 or IPv6. Continue reading »
Google has another new thing they are doing, called FLOC (Federated Learning of Cohorts). It’s used to — surprise — track user activity across websites. Opting out ideally is handled by the user, who can customize their browser settings to disable FLOC while surfing around the Web. Beyond configuring your browser to opt-out of FLOC, you can disable it on any website with a single line of code. Continue reading »
Let’s say you have some .htaccess rewrite rules in place using Apache’s mod_rewrite. By default if the rewrite rules are located in the root directory, they will be applied to every subdirectory, as expected. But what if you need to disable the rewrite rules so that they do not affect some specific sub-directory or sub-folder? This super quick tutorial shows the easiest way to do it. Continue reading »
After several months of development, the official Nginx version of the 7G Firewall is out of beta and ready for public use. If you are not familiar with 7G Firewall, check out the documentation for the Apache/.htaccess version. The Nginx version of the 7G Firewall works the exact same way, so I won’t bother repeating everything here. The only difference is the implementation, how to set it up on an Nginx server, which is explained in this post. Continue reading »
