Jail, a Virtual Machine Facility for Risk
Management in FreeBSD


Speaker:
Poul-Henning Kamp


The “jail” facility in FreeBSD was developed for giving
multiple untrusted customers root access to their own virtual
machines on the same physical machine. Experience has shown
that it has many other security enhancing uses as well. This
talk will introduce the audience to the jail facility, show
examples of how to use it and talk about the implementation
and the limitations.
