4 Select another expression that you will use to form a new logical expression

in combination with the first.

5 Using the radio buttons, select the type of expression you wish to construct, in

this example an AND expression.

The AND expression lets you construct a logical expression where both

conditions must be met for the TunnelGuard checks to pass. The OR

expression lets you construct an expression where either of the conditions

must be met for the TunnelGuard checks to pass. The NOT operand lets you

construct an expression where the condition must not be met for the

TunnelGuard checks to pass, for example the file or files in the software

definition must not be found on the client machine.

6 Click the Form TunnelGuard Rule Expression button.

A new expression is created and copied to the Available Expressions area (see

Figure 88 on page 336).
