Using the wizard to create signatures

The signature creation wizard is the recommended method if you are new to creating signatures. The wizard offers two dialog boxes where you enter the necessary information for the signature, but it does not offer any flexibility for the operations that the signature is protecting because you cannot change, add, or delete operations.

To create signatures using the wizard:

1On the Signature toolbar, click Signature Creation Wizard.

2In the Signature Creation Wizard - Step 1 of 2 dialog box, enter a name and a description, select the platform and severity level, and then click Next.
