The content filters are installed between the internal switch and firewall or router. Have the outgoing and incoming traffic from the Internet through to apply such filters. They are usually referred to as bridged mode.
Effective monitoring is of paramount importance to computer network security. It helps in competent management of networks, in which the activity log of routers and diverse servers can be closely watched and reported.

Another aspect of the computer network assigns permissions several users in the network. For example, senior management may want to review the systems of their subordinates or teams. They will be awarded with limited admin rights to be treated in their group. They may not necessarily be given admin rights for the entire network. You could also block users to install software from their workstations. In the same way you can prevent them access to their systems through portable storage devices. In short, the entire network must be clearly identified.
Finally, the physical security are also very important for the overall security aspects of the computer network.
