Designing Security

Gone are the days when you could ignore security and get away with it. Everyday, it seems, the media report yet another software virus or Web site break-in. Yet, if you apply security crudely, your end users might complain of having to enter the same logon ID and password multiple times. What you and your end users want is tight security with a clean user interface.

To achieve this goal, use the security tools described in this chapter. The tools are:

Security Tool
Description
Digital Signatures

The application deployer digitally signs each cabinet file to be downloaded, and the end user verifies each digital signature when the file downloads.

User IDs and Passwords

The application deployer assigns a user ID and password to each server accessed by WebClient and the application.

Security Caching

WebClient caches each user ID and password entered by the end user and retrieves cached authentication information to access additional objects that require the same user ID and password.

Secure Communication Protocols

The application deployer chooses communication protocols that can encrypt downloads.
