Securing Your Environment

As corporate networks become integrated with the Internet and other external networks, the threat of unauthorized access to your corporate 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.

These are some of the questions that must be answered as you plan how to secure your SNA Server environment:

• How can I authenticate users who require host resources?
• How can I control access to host resources?
• How can I control sensitive data flowing between workstations and host applications?
• How can I maintain security while connecting my host network to external sources like the Internet?
• How can I make host resources easier to access for authenticated users, yet maintain a secure and easy-to-administer host environment?

This chapter helps answer these questions and describes how to implement SNA Server’s security features to create a secure LAN-to-host environment.
