A WARP is set up to provide a service to members of a particular community, usually of between 20 and 100 members (in order to preserve a personal community feel).
It is run by a WARP operator who uses a website, email, telephone, SMS, and occasional meetings (where possible) to offer a personalised service of information security warnings and advice to the members.
The creation of WARPs in Public Sector communities, where people work together and share information on threats, incidents and solutions, can address many of these problems in a cost effective manner. WARPs are also being promoted by the UK Government’s Centre for Protection of National Infrastructure (CPNI).
