Keep SELinux enforcing on Fedora. Fix denials by labeling paths with semanage fcontext, using booleans via setsebool -P, and writing narrow custom policy modules (reviewed, not raw audit2allow). Worked examples for httpd on /srv/webapp, remote DB connections, and a custom module.
Learn how to configure SELinux enforcing mode for Apache on CentOS 8/9 to prevent 403 Forbidden errors and secure web content using security contexts and booleans.
Step‑by‑step guide to switch CentOS 7 or CentOS Stream 8 to SELinux enforcing mode, verify the change, diagnose denials with audit2why/audit2allow, and roll back safely if services break.
Enable SELinux in enforcing mode on CentOS 8/Stream, tweak the config, toggle at runtime, and verify policy enforcement with audit logs and context checks.
Enable a user‑defined Fedora service to bind to port 8080 by creating a custom SELinux policy module, labeling the binary, and loading the module. Follow the step‑by‑step guide to keep SELinux enforcing and avoid common pitfalls.
Goal Determine how to reliably toggle an SELinux boolean on CentOS and ensure the change survives a reboot, while also understanding the impact on already-running containers. Current behavior The semanage boolean tool updates the active boolean file, but the kernel does not reload the value until a reboot or a setsebool -P command is issued. On CentOS 8 and
A design review is needed for systemd service units on RHEL 8 and RHEL 9 where the same unit file is intended to run in a local development context and in a production environment. The goal is to clarify which configuration behaviors are deterministic across environments and which are dependent on host policy. Relevant constraints include systemd service har
Policy Selection Context AlmaLinux 9 ships with the targeted SELinux policy enabled by default, which permits common network services while confining processes to their domains. The alternative minimum targeted policy reduces the set of active booleans, providing a stricter sandbox at the cost of requiring manual enablement for each service capability. Migra
SELinux and LUKS Integration in Rocky Linux 9.x Rocky Linux 9.4 supports LUKS full-disk encryption via systemd-hibernate and cryptsetup, with XFS as the default filesystem and ext4 on /boot for bootloader compatibility. SELinux enforces mandatory access controls beyond traditional Unix permissions, but the interaction between encrypted volume mounting and SE
