Application of Enterprise Intranet Security
The router located between the enterprise intranet and external networks, ensures information security on the entire intranet and intranet LANs.
As shown in Figure1, the enterprise intranet is connected to the external network through the Router. The router can prevent external users from accessing the enterprise intranet. For example, external users can access the enterprise external server but cannot access the enterprise internal server. The financial department and marketing department have individual LANs on the intranet. To allow the users on the intranet to access the external network, configure network address translation (NAT) on the intranet.
The router ensures information security on the enterprise intranet in the following modes:
- Enabling packet filtering or stateful firewall on the Router to isolate the enterprise intranet from external networks. This prevents unauthorized external users from accessing the intranet.
- The router provides network access control (NAC) to restrict the access permissions of internal users. This ensures that only authorized users can access the intranet.
IPS defends against attacks, provides secure environments for enterprise networks, and accurately manages network resources.
