Charter: Scope The working group will list capabilities appropriate for devices used in: * Internet Service Provider (ISP) Networks * Enterprise Networks The following areas are excluded: * Wireless devices * Small-Office-Home-Office (SOHO) devices * Security devices (firewalls, Intrusion Detection Systems, Authentication Servers) * End Hosts The plan is to have multiple small documents IETF-61 OPSEC WG

Charter: Outputs Framework Document Current Practices Document The plan, scope, etc Current Practices Document * threats addressed, * current practices for addressing the threat, * protocols, tools and technologies extant at the time of writing Individual Capability Documents The detail for the various categories Profile Documents IETF-61 OPSEC WG

Charter-related issues There are a lot of documents The document tradeoff: One really big on versus many tiny ones. We need lots of editors  IETF-61 OPSEC WG
