A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part of network documentation.
Network Enclaves consist of standalone assets that do not interact with other information systems or networks. A major difference between a DMZ or demilitarized zone and a network enclave is a DMZ allows inbound and outbound traffic access, where firewall boundaries are traversed. In an enclave, firewall boundaries are not traversed.
The external network is formed from the ISP to the firewall on the first network interface, the internal network is formed from the second network interface, and the DMZ is formed from the third network interface. The firewall becomes a single point of failure for the network and must be able to handle all of the traffic going to the DMZ as ...

Homegroup is a feature that allows shared disk access, shared printer access and shared scanner access among all computers and users (typically family members) in a home, in a similar fashion as in a small office workgroup, e.g., by means of distributed peer-to-peer networking (without a central server). Additionally, a home server may be added ...
Different network types have different firewall policies. An open network such as a public wireless network is classified as Public and is the most restrictive of all network settings. In this mode other computers on the network are not trusted and external access to the computer, including sharing of files and printers, is disabled.
Once the policy is met, the computer is able to access network resources and the Internet, within the policies defined by the NAC system. NAC is mainly used for endpoint health checks, but it is often tied to Role-based Access. Access to the network will be given according to the profile of the person and the results of a posture/health check.
Moving from a flat network to a segregated network without changing the IP addressing of the hosts. A firewall can replace a router, and then hosts can be slowly moved to their secondary VLAN assignment without changing their IP addresses. There is a need for a firewall with many tens, hundreds or even thousands interfaces.
