Overview
Going to be compiling mod_security2 (v2.9.7) for Apache2 on Ubuntu 22.04. This module is pretty straight forward to compile. However, there are some dependencies.
sudo apt install apache2-dev gcc libxml2 libxml2-dev libpcre3-dev
If you already have libapache2-mod-security2 installed via apt then disable and uninstall it.
sudo a2dismod security2 sudo apt purge libapache2-mod-security2
Then fetch the latest tarball from their github releases page. Then compile it using normal make cmds.
https://github.com/owasp-modsecurity/ModSecurity/releases/tag/v2.9.7
sudo su cd /opt wget https://github.com/owasp-modsecurity/ModSecurity/releases/download/v2.9.7/modsecurity-2.9.7.tar.gz tar -xzvf modsecurity-2.9.7.tar.gz cd modsecurity-2.9.7 ./configure --with-apxs=/usr/bin/apxs make make install echo 'LoadModule security2_module /usr/lib/apache2/modules/mod_security2.so' > /etc/apache2/mods-available/security2.load a2enmod security2 systemctl restart apache2
Then you should be able to see mod security enabled and working in the Apache error logs.
