LAN-to-Host Security

  • Article

As your network becomes integrated with the Internet and other external networks, the threat of unauthorized access to your network resources grows significantly. When you plan your networking environment, you must strike the right balance between protecting your resources and allowing your users unobstructed access.

As you plan how to secure your SNA Server environment, you should consider methods to:

  • Authenticate users who require host resources.

  • Control access to host resources.

  • Control sensitive data flowing between workstations and host applications.

  • Maintain security while connecting your host network to external sources like the Internet.

  • Make host resources easier to access for authenticated users, yet maintain a secure and easy-to-administer host environment.

The following sections address each of these issues and describe how to implement SNA Server security features and Windows 2000 security features to create a secure LAN-to-host environment.
