Improving Network Security Through The Use of Host Rings
Geoff Halprin
Topic: Security
Audience: Intermediate users
Description:
Much work has been done in recent years on Internet Firewall technology. This technology creates a "choke point"
through which all traffic must pass between (typically) the Internet and the internal network. This technology is
equally useful wherever a clear separation can be made between any two networks where one does not trust the
other.
This is extremely valuable technology in the fight to control the security of a network. The basic assumption that
this technology makes, however, is that everybody on the outside is bad and everybody on the inside is good.
In order to bring better control and security to an internal network, another security model is required. This model
needs to recognise that physical and logical security attributes, and the separation of functions, as is commonplace
with good client-server network design, can contribute to identifying where and what type of trust should exist
between hosts.
This paper describes the host rings model, how it can be implemented, the advantages of this model, and
experiences with implementing it at various sites.
