Nsaas -- *NSaaS: Network Security as a Service mailing list*
About Nsaas	English (USA)
> Network Security as a Service (NSaaS) mailing list is for discussing > topics related to protocols (or the interface) and architectures for > “Requesters” to negotiate the network security related functions, that are > not physically present at Requesters’ premises, as well as the associated > attributes. > > The security functions under discussion are the ones that can be requested > by one domain (e.g., two different domains of one service provider, > enterprise clients, or applications, etc.) but may be owned or managed by > another domain (e.g., service provider). Those security functions may be > hosted on physical appliances or instantiated as virtual machines on common > compute server (i.e. the Virtualized network functions defined by ETSI > NFV). > > The “requester <-> provider” relationship has different connotations in > different scenarios: > > · Client <-> Provider relationship, i.e. client requesting some > network functions from its provider; > > · Inter-domain, e.g. Domain A <-> Domain B relationship, i.e. one > operator domain requesting some network functions from another operator > domain, where “A” and “B” can be from same operator or different operators; > or > > · Applications <-> Network relationship, i.e. an application (e.g. > cluster of servers) requesting some functions from network, etc. > > > > The security functions offered by 3rd party need Bi-directional periodic > communications between the requesters and the providers for policy > negotiation, validation, potentially re-directing traffic to higher level > security functions, etc. Therefore, the service requires protocol exchange. > Simply, an API is not enough. > > The proposed protocols between requester and provider can be used for the > following scenarios: > > · A Client requests a certain network security function from a > provider > > · The provider fulfills the request for example, by instantiating > an instance of the service in question, or configures additional rules in > an already provisioned service. > > > > Even though OpenStack has done a project on FW as a service: > https://datatracker.ietf.org/doc/draft-dunbar-nsaas-problem-statement/, the > specifications are very primitive, far from enough for NSaaS, due to it is > open source code and there is no validation on its accuracy or > completeness. Our goal is for IETF to take up the role of defining the > complete specification, and providing a hand-off to OpenStack or other Open > Source communities to provide the source code. > To see the collection of prior postings to the list, visit the Nsaas Archives.
