CIDRAM (short for “Classless Inter-Domain Routing Access Manager”) is a powerful web security tool that helps protect websites from malicious traffic. It uses a combination of IP blocking, HTTP header analysis, and other techniques to identify and block threats in real-time. CIDRAM is open-source software and can be easily integrated into various web applications, including WordPress, Drupal, and Joomla.
In this article, we will discuss the importance of CIDRAM in web security and its main features. We will also look at how CIDRAM works, how it can be installed and configured, and how it can be used to enhance the security of your web applications.
What is CIDRAM?
As the internet continues to grow and evolve, so do the threats that come with it. One of the most significant threats facing website owners and users alike is the risk of cyberattacks, which can result in data breaches, identity theft, and other forms of digital crime. To help protect against these threats, a variety of security tools and techniques have been developed, including Content-Intrusion Detection and Response Advanced Module (CIDRAM). By implementing CIDRAM on a website, site owners can enhance their security measures and reduce the risk of cyberattacks.
The tool works by analyzing incoming traffic and comparing it to a set of rules and filters, which are based on IP addresses, user agents, referrers, and other parameters.
CIDRAM’s main goal is to prevent various types of attacks, such as brute-force attempts, SQL injections, cross-site scripting, and others. By filtering out suspicious traffic, it helps to reduce the server load, improve the website’s performance, and enhance the overall security posture. Additionally, CIDRAM provides various customization options, allowing developers to tailor its settings to their specific needs and configurations.
The development of the project started in 2016 by Caleb Mazalevskis, who was looking for a way to effectively protect his websites from malicious visitors. It gained popularity over time, with more and more users adopting it for their own websites. The project has a strong community of contributors and users who help with its development and provide support to others. While there are other competitors in the web security space, CIDRAM’s unique features and ease of use have made it a popular choice among web developers.
How does CIDRAM work?
With a basic understanding of what CIDRAM is and why it’s important, let’s take a closer look at how it actually works. In this section, we’ll explore the key components of CIDRAM and how they work together to provide powerful protection against malicious traffic. From the initial request to the final decision on whether to allow or deny access, we’ll examine the steps involved in CIDRAM’s filtering process and the algorithms used to detect and block potentially harmful requests.
How CIDRAM blocks IP addresses
CIDRAM blocks IP addresses based on its IP database, which is regularly updated with the latest threat data. The database contains a list of IP addresses and ranges associated with malicious activity, such as spamming, phishing, and hacking attempts. When a request is made to a website protected by CIDRAM, the user’s IP address is compared to the entries in the database. If there is a match, the request is denied and the user is blocked from accessing the website.
CIDRAM uses a scoring system to determine the risk level of an IP address. Each entry in the database is assigned a score based on the severity of the threat it poses. When a request is made, CIDRAM calculates a score for the user’s IP address based on its history and the number of hits it has received. If the score exceeds a certain threshold, the user is blocked from accessing the website.
CIDRAM also uses a variety of other techniques to detect and block malicious activity. These include blacklisting of known bad IP addresses, whitelisting of known good IP addresses, and rate limiting to prevent brute force attacks. Overall, CIDRAM provides a comprehensive and effective solution for protecting websites from a wide range of security threats.
CIDRAM’s algorithms and filters
CIDRAM’s algorithms and filters are at the core of its functionality. The system employs various algorithms to determine whether or not an incoming IP address should be blocked. These algorithms include blacklist and whitelist checks, as well as pattern matching and user-defined rules. CIDRAM also uses a filtering system to determine which types of requests should be blocked or allowed. This filtering system can be customized to suit the specific needs of the website owner.
CIDRAM’s filters include country-based blocking, blocking of specific IP ranges, and detection of malicious requests based on patterns or signatures. Additionally, CIDRAM includes a real-time IP address lookup system to determine whether or not an IP address is associated with malicious activity. This lookup system includes integration with various databases and APIs to provide up-to-date information on IP addresses.
CIDRAM’s algorithms and filters work together to create a powerful and flexible system for blocking malicious IP addresses and requests. The system is designed to be customizable, allowing website owners to tailor CIDRAM’s functionality to meet their specific needs.
Comparison of CIDRAM with other security tools
CIDRAM is just one of many web security tools available today. Some of its competitors include ModSecurity, Fail2Ban, and NAXSI.
ModSecurity is an open-source web application firewall (WAF) that works as an Apache or Nginx module. It can monitor and analyze HTTP traffic in real-time, detect and block various types of web attacks, and log relevant information for further analysis. ModSecurity offers a wide range of security rules that can be customized and updated regularly to keep up with the latest threats.
Fail2Ban is another open-source tool that monitors log files and blocks IP addresses that have repeated failed login attempts or other suspicious behavior. It can be used for a variety of services, such as SSH, FTP, and Apache, and supports different ban actions, such as blocking IP addresses for a certain period of time or sending notification emails.
NAXSI is a WAF that uses a negative security model to block requests that match predefined rules. It can be used as a standalone WAF or as a module for Nginx. NAXSI is designed to be lightweight and easy to configure, and it offers a range of security rules that can be adjusted according to the specific needs of a website.
When it comes to comparing CIDRAM with these tools, it’s important to note that each one has its own strengths and weaknesses. For example, ModSecurity offers a wide range of security rules, but it can be complex to set up and maintain. Fail2Ban is easy to use and can be customized for different services, but it may not be effective against sophisticated attacks. NAXSI is lightweight and easy to configure, but it may require more advanced knowledge to use effectively.
CIDRAM, on the other hand, offers a lightweight and modular solution that is designed to be easy to use and highly customizable. It uses a range of algorithms and filters to block malicious requests and has a flexible configuration system that allows users to define their own custom rules. While CIDRAM may not offer the same range of features as some of its competitors, it provides a solid and reliable solution for web security that is well-suited for smaller websites and projects.

Installation and Configuration of CIDRAM
- Installation with Composer CIDRAM is registered with Packagist, so you can use Composer to install CIDRAM. Run the following command to install CIDRAM:
composer require cidram/cidram
- Configuration After installing CIDRAM using Composer, you need to configure it to protect your website. To do this, create an “entrypoint” which consists of three things:
- Inclusion of the “loader.php” file at an appropriate point in your codebase or CMS.
- Instantiation of the CIDRAM core.
- Calling the “protect” method.
Here’s a simple example:
<?php require_once '/path/to/the/vault/directory/loader.php'; (new \CIDRAM\CIDRAM\Core())->protect();
If you’re using an Apache webserver and have access to php.ini, you can use the auto_prepend_file directive to prepend CIDRAM whenever any PHP request is made. In such a case, the most appropriate place to create your entrypoint would be in its own file, and you would then cite that file at the auto_prepend_file directive.
auto_prepend_file = "/path/to/your/entrypoint.php"
Or this in the .htaccess file:
php_value auto_prepend_file "/path/to/your/entrypoint.php"
In other cases, the most appropriate place to create your entrypoint would be at the earliest point possible within your codebase or CMS to always be loaded whenever someone accesses any page across your entire website. If your codebase utilizes a “bootstrap”, a good example would be at the very beginning of your “bootstrap” file. If your codebase has a central file responsible for connecting to your database, another good example would be at the very beginning of that central file.
Best Practices for Using CIDRAM
Tips for optimizing CIDRAM performance
