![]() Server and Domain Isolation Using IPsec and Group PolicyBrief DescriptionThis guide provides business-oriented justification as well as technical guidance for logically isolating servers and domains from certain types of network traffic through the use of IPsec filters and Group Policy. On This PageQuick Details
OverviewThe Server and Domain Isolation Using IPsec and Group Policy solution guide provides technical guidance, but it also provides documentation to help you understand the business benefits of using server and domain isolation to defend IT systems against internal and external security threats. The technical guidance shows how to use IPsec and Group Policy to secure and manage different types of networks, including those that have VPN clients and internal firewalls. Troubleshooting documentation is also provided that describes how to resolve frequently encountered IPsec issues. The guidance is supplemented with tools and templates that can be used to assist the project team during all stages of the project lifecycle. Server and domain isolation can be an important strategy in the defense against virus propagation, internal hackers, employee misuse of technology assets, and information theft. It can also be used to require domain membership of all clients that seek access to trusted resources, either clients or servers, so that they can be better managed by professional IT staff. Server and domain isolation can also be used as either a primary or an additional strategy for meeting data privacy or other data protection requirements. It can be used without modifying existing Microsoft Windows applications or deploying virtual private networking (VPN) tunneling hardware on the network. Server and domain isolation allows IT administrators to restrict TCP/IP communications of domain members that are trusted computers. These trusted computers can be configured to allow only incoming connections from other individual trusted computers or a specific group of trusted computers. The access controls are centrally managed by using Group Policy (a feature of the Active Directory directory service) to control network logon rights. Nearly all TCP/IP network connections can be secured without application changes, because IPsec works at the network layer (below the application layer) to provide authentication and per-packet, state-of-the-art, end-to-end security between computers. Network traffic can be authenticated, or authenticated and encrypted, in a variety of customizable scenarios. Group Policy and IPsec configurations are centrally managed in Active Directory.
