selinuxlab

This is an Ansible playbook and related files to set up a SELinux Lab on Redhat Enterprise Linux for educational purposes.

Authors

• Lukas Vrabec lvrabec@redhat.com
• Luc de Louw ldelouw@redhat.com

Cases covered:

• Setting wromg permissions to /etc/shadow and see that SELinux prevents information disclosure by a CGI script trying to read the shadow file
• Setting up an NFS Server with protocol version 4.2 which exports SElinux file contexts
• Setting up a simple SMB Server for two use cases: Home directory mount and mount of a generic share
• Installation of a Tomcat server with a example application to be confined

Operating Systems

This playbook and lab has been tested with the following Operating Systems:

• RHEL8
• RHEL9
• RHEL10 (actually with CentOS Stream 10 which is the upstream project of the upcomming RHEL10 system)

Usage:

ansible-play -u root -k setup-lab.yml

Future development

This repo will be updated as the lab will evolve. We are happy to get input from other contributers.
