- FreeBSD Jails and Podman containers are compared in terms of security.
- Jails do not require a minimal system image, reducing attack surface compared to Podman.
- Both 'rootless' Podman and Jails use a virtual root user, not the host's root.
- Jails provide better isolation than Podman, even without additional security layers.
- Jails restrict FreeBSD kernel syscalls by default, unlike Podman which requires SELinux/seccomp.
- Jails can use dedicated physical network interfaces, while Podman cannot in 'rootless' mode.
- Jails can run dedicated firewalls internally, enhancing security.
- Jails have been in production since 1999, making them more battle-tested than Podman.
- FreeBSD has significantly fewer CVEs (557-649) compared to Linux (10064).
- Jails have 0.7 CVEs per year, while Podman has 5, indicating better security for Jails.
