The communications requirement:
Secure remote access from geographically distributed LANs (subsidiaries, branch offices etc.) to the central data network (also referred to as banch office networking).
Access can be either "direct" (company telephone number), or "indirect" via the Internet (ISP telephone number + IP address of the destination system). DSL connections serve as the transmission media, due to the required bandwidth.
There are various ways of connecting decentralized LANs to the corporate network:
1. The Secure Client must be installed on each LAN PC
2. All LAN PCs access the central corporate network via a shared
2. All LAN PCs access the central corporate network via a shared
Secure Gateway. Installation of the gateway depends on the respective conditions:
- If IP router is already present, Installation of the Secure Gateway in the LAN, either as a dedicated computer, or integrated on the file server
- If no IP router is present, Installation of the Secure Gateways with WAN connectivity, either as dedicated computer, or integrated on the file server, in which case the server must also be equipped with WAN adapters.
- If neither IP router nor dedicated Secure Gateway is present Installation of an appliance with integrated Secure Gateway and WAN connectivity
NCP Secure Communications for remote LANs offers the following range of services:
- End-to-end security between LAN PC, or subsidiary gateway, and the central gateway
- Optional use of OTP tokens (One Time Password) or electronic certificates (as soft certificates, on smart cards, or USB tokens) in a PKI for individual User-Authentification.
- Features in the public wireless network environment, see Secure Mobile Computing
- Features in the WLAN environment, see Secure WLAN
