FreeBSD Jails is a robust and flexible security feature native to the FreeBSD operating system, which allows administrators to partition a FreeBSD-based computer system into several independent mini-systems called "jails". This technology enhances security, system stability, and containment without the overhead of starting virtual machines. Each jail operates like a separate instance of FreeBSD, with its own users and applications, and it can be configured with its own IP addresses, while still sharing the host system\'s kernel. Jails are widely utilized for a variety of purposes including hosting environments, testing environments, and isolated secure areas for potentially risky operations.For detailed documentation, further resources, and updates on FreeBSD Jails, you can visit their dedicated wiki page at [https://www.wiki.freebsd.org](https://www.wiki.freebsd.org), although it appears this link may be incorrect or outdated. For accurate and up-to-date information, the official FreeBSD website and handbook section on Jails should be consulted.
