ABSTRACT
Under this design, one of the simplest definitions comes from R.H. Baker: “An extranet is an intranet that is open to selective access by outside parties.”
The critical security concept of the extranet is the new network area that was previously excluded from external access now being made available to some external party or group. The critical security issue evolves from the potential vulnerability of allowing more than the intended party, or allowing more access than was intended originally for the extranet. These critical areas will be addressed in this chapter, from basic extranet set-up to more complex methods and some of the ongoing support issues.
