    abstract =  {This document describes the Security Policy Specification Language (SPSL), a language designed to express security policies, security domains, and the entities that manage the policies and domains. The syntax and semantics of the language are presented here. SPSL currently supports policies for packet filtering, IP Security (IPsec), and IKE exchanges. However, it may easily be extended to express other types of policies.},
