Shadow Daemon – Web Application Firewall with Modular Architecture and User Interface



Shadow Daemon uses small connectors on application level to intercept requests.This guarantees that the analyzed data is exactly the same as the input data of the web application, a task many firewalls fail to do properly.




Shadow Daemon – Web Application Firewall



Unlike many other web application firewalls, Shadow Daemon does not completely block malicious requests if possible.Instead, it only filters out the dangerous parts of a request and lets it proceed afterward.This makes attacks impossible but does not unnecessary frustrate visitors in the case of false-positives.


Shadow Daemon is closer to the application than most other web application firewalls.It receives exactly the same input that the web application receives and thus it is almost impossible to bypass the detection by obfuscating the attack.However, the most complex parts of Shadow Daemon are separated from the web application to guarantee a certain standard of security.


If you own an internet business, you must prevent hackers from destroying your website. If your website becomes infected with hacker code, search engines will not link to it. Protect your organization with a firewall for web applications.


A web application firewall (WAF) is a form of application firewall that provides visibility and analysis of HTTP(S) traffic to and from an online application. Its purpose is to thwart attacks designed to refuse service and steal data. It grants the administrator direct control over the requests and replies flowing through the system without requiring modification of the backend code. A WAF differs from a conventional firewall in that it protects a particular online application or group of web apps. And it does so without interacting with online apps.


Naxsi may examine many data, including URLs, request parameters, cookies, headers, and the POST body, and it can be enabled or disabled at the location level in the Nginx configuration. Automatic whitelist generation simplifies upstream firewall deployment and eliminates any false positives. Other applications, such as NX-Utils and Doxi, simplify administration, report production, and ruleset modifications.


Shadow Daemon is a suite of tools designed to identify, record, and prevent web application attacks. The Shadow Daemon is technically a web application firewall that intercepts requests and removes harmful parameters. It is a modular solution that isolates online applications, analyses, and interfaces in order to boost security, flexibility, and scalability.


The Shadow Daemon, unlike many other web application firewalls, does not entirely block malicious requests whenever feasible. Instead, it removes just the potentially harmful components of a request before allowing it to proceed. This prevents attacks while not needlessly frustrating visitors in the event of false positives.


OctopusWAF is an open-source Web application firewall written completely in C that makes numerous connections using libevent. The event-driven design is geared for many concurrent connections (keep-alive), which is essential for AJAX applications with high speed. This tool is quite lightweight. You may use it in any desired manner. This resource is ideal for securing particular endpoints that require customized security.


At the 2011 RSA Conference, Qualys, Inc., the leading supplier of on-demand IT security risk and compliance management solutions, introduced IronBee, a new open source project that will deliver the next generation of web application firewall (WAF) technology.


ModSecurity sometimes referred to as Modsec, is an open-source web application firewall (WAF). Originating as a module for the Apache HTTP Server, it has grown to include a variety of Hypertext Transfer Protocol request and response filtering capabilities as well as other security features across several platforms, including Apache HTTP Server, Microsoft IIS, and Nginx. It is free software distributed under the Apache 2.0 license.


The NGINX ModSecurity WAF is a web application firewall (WAF) based on ModSecurity 3.0, a rewrite of the original ModSecurity software that functions as a native dynamic module for NGINX Plus. The NGINX ModSecurity WAF may be used to prevent a wide variety of Layer 7 attacks and adapt to new threats with virtual patching. Despite having a free version, NGINX ModSecurity is not an open-source project, so keep that in mind.


When searching for a WAF for your server, several open source choices will appear in the search results. Open source projects give a clear image of what is required in a web application firewall and how they function, making this a suitable starting point.


However the If I remove the Flask Connector part the application works good. I don't find much documentation in shadowd. Does anyone have Idea on the above issue? Kindly help me out.


Shadow Daemon is a collection of tools to detect, protocol and prevent attacks on web applications. Technically speaking, Shadow Daemon is a web application firewall that intercepts requests and filters out malicious parameters. It is a modular system that separates web application, analysis and interface to increase security, flexibility and expandability.


Unlike many other web application firewalls Shadow Daemon does not completely block malicious requests. Instead it only filters out the dangerous parts of a request and lets it proceed afterwards. This makes attacks impossible, but does not unnecessary frustrate visitors in the case of false-positives.


Shadow Daemon is closer to the application than most other web application firewalls. It receives exactly the same input that the web application receives and thus it is almost impossible to bypass the detection by obfuscating the attack. However, the most complex parts of Shadow Daemon are separated from the web application to guarantee a certain standard of security.


  • SecRuleEngine Off: It will deactivate the ModSecurity firewall on the server.SecRequestBodyAccess: It will tell ModSecurity whether it will check the body of the request or not. It plays a very important role when a web application is configured in way where all data go in POST request. It has only two parameters, ON or OFF. We can set that according to the requirement.

  • SecResponseBodyAccess: If this parameter is set to be On in the whiltelist.conf file, then ModSecurity will analyse the server response and do the appropriate action accordingly. It also has only two parameters, ON or Off. We can set it according to the requirement.

  • SetDataDirectory: In this section we will have to define the ModSecurity working directory. This directory will be used by the ModSecurity for temporary purposes.

ModSecurity is now successfully configured with the OWASP rules. Now we will test the ModSecurity firewall against some of the most common web application attacks and will verify weather ModSecurity is blocking the attacks or not.


In order to do that, we will try to launch the reflected Cross Site Scripting (XSS) attack on the website in which we have configured ModSecurity. The most common XSS vulnerable field in a website would be the search box, in which a user could search anything on the website. If a malicious user tries to inject Java Script or HTML script in the search box, it will execute in the browser. We can type alert(123) in the search box. In a normal scenario (when we do not have any kind of application firewall on the server) it will show a popup message on the website if the website is vulnerable for XSS.


Next-generation firewalls (NGFW) took this to the next level. They often include deep packet inspection (DPI) and intrusion detection systems (IDS) that allows the firewall to open up IP packets and look at their contents, even up to the application layer. For instance, an IDS might analyze packets to discover what type of messages they contain. Is this FTP? VoIP? HTTP traffic from video streaming or social media websites? Or is it a virus, matched against a set of known signatures?


Hi for best security practise , I would like to install Shadow deamon (web application firewall) in virtual environement using vmware workstation 16.x..I install docker , download the file from git -> git clone


NGINX App Protect WAF provides web application firewall (WAF) security protection for your web applications, including OWASP Top 10; response inspection; Meta characters check; HTTP protocol compliance; evasion techniques; disallowed file types; JSON & XML well-formedness; sensitive parameters & Data Guard. Refer to Supported Security Policy Features section for more detailed description.


Many organizations migrate to the cloud and deploy their respective cloud provider's web application firewall to mitigate volumetric DDoS attacks. These providers offer security groups similar to a stateful firewall that allow users to block unwanted protocols and ports. However, this technique does not block traffic on the protocols or ports your application relies on. Though it will prevent bogus traffic floods from reaching the application.


No discussion of web application firewalls is complete without a look at the downside, and web application firewall vulnerabilities do exist. WAFs are deployed at the network edge and work to stop suspicious and malicious traffic. This filtering was originally rules-based, either from the WAF vendor for out of the box use, or customized by users.


WAFs are an important addition to a suite of tools to address these problems. A web application firewall can fortify an application security program with an essential extra layer of defense. WAFs can also help security professionals maintain more control. Security teams can monitor based on predetermined rules and guidelines to alert for possible attacks in progress.


The distinction between web application firewalls and network firewalls is based on differences in the types of protection. A traditional firewall guards against unauthorized network access and blocks traffic from particular areas or IP ranges. 2ff7e9595c
