Because of the replication architecture, laptops carry sensitive corporate information. If your laptop is lost or stolen, security breaches can (and often do) occur. • Could generate some serious network traffic, depending on the number of users per server. • Remote users often get discouraged waiting for large files to load. Both remote control and remote nodes have been developed to support remote users. The one that is best for you depends on your computing 32 AU1253_ch03_Frame Page 33 Saturday, October 26, 2002 4:21 PM Remote Access Functions environment and the method you use to provide the most features, functionality, ease of use, and security.
By consolidating access points into a single gateway, these resources become shared. Network integrity can be maintained by providing an appropriate level of security on the remote access server. Most remote access servers provide several levels of security and can work in conjunction with thirdparty security and authentication devices. All accesses through the remote access server are centrally logged. Pros: • Manageable; centralized management • Efficient; shared resources (modems and phone lines) • Can be integrated with third-party authentication Cons: • Not suitable for graphic-intensive applications Security issues: • Host screen should be blanked out • Host keyboard should be disabled INTEGRATED SOLUTION This method incorporates a combination of the previous methods such as remote node, remote control, and terminal servers, in one box (see Exhibit 6).
The host system can be any computer attached to the LAN that is configured for remote access. With remote control, mobile workers using laptops or branch office workers using workstations take control of PCs on the corporate network. All the user’s keystrokes and mouse movements are sent to the corporate PC, and the image on that screen is forwarded back to the laptop for display. It is as if the user were sitting in front of a network-attached PC. Remote users do not need copies of programs on their computers, because the programs actually run on LAN-attached workstations at the corporate headquarters.
