Shadow Daemon is a collection of tools to detect, record 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.

This is the main component that handles the analysis and storage of requests.

Use cmake to configure and prepare the project. It is a good idea to create a separate directory for this. A typical installation might look like this.

mkdir build
cd build


If cmake is successful it creates a makefile. Use it to compile and install the project.

make shadowd
make install


Install and configure a database server. At the moment shadowd officially supports PostgreSQL and MySQL. Afterwards create a new user and database for shadowd and import the correct layout.

If you are using PostgreSQL you can use psql to import the layout.

psql -Ushadowd shadowd < /usr/share/shadowd/pgsql_layout.sql

If you are using MySQL you can use mysql to import the layout. The user requires the CREATE ROUTINE privilege.

mysql -ushadowd -p shadowd < /usr/share/shadowd/mysql_layout.sql


The installer copies the configuration file to /etc/shadowd/shadowd.ini. The file is annotated and should be self-explanatory.
