DESCRIPTION

Customer

Use this part of the screen to import custom signatures (previously saved

Signature Rule

to your computer) to the ZyWALL.

Importing

 

 

Note: The name of the complete custom signature file on the

 

ZyWALL is ‘custom.rules’. If you import a file named

 

‘custom.rules’, then all custom signatures on the ZyWALL are

 

overwritten with the new file. If this is not your intention, make

 

sure that the files you import are not named ‘custom.rules’.

 

 

File Path

Type the file path and name of the custom signature file you want to

 

import in the text box (or click Browse to find it on your computer) and

 

then click Import to transfer the file to the ZyWALL.

 

New signatures then display in the ZyWALL IDP > Custom Signatures

 

screen.

 

 

30.8.1 Creating or Editing a Custom Signature

Click the Add icon to create a new signature or click the Edit icon to edit an existing signature in the screen as shown in Figure 297 on page 499.

A packet must match all items you configure in this screen before it matches the signature. The more specific your signature (including packet contents), then the fewer false positives the signature will trigger.
