Chapter 38 Defining IPS Signatures
Configuring Signatures
IPS signature purge now runs at midnight every day.
Configuring Signatures
The Signatures policy is where you configure signatures for Cisco IPS sensors and Cisco IOS IPS
devices.
This section contains the following topics:
• Signatures Page, page 38-4
• Viewing Signature Update Levels, page 38-9
• Enabling and Disabling Signatures, page 38-10
• Editing Signatures, page 38-11
• Adding Custom Signatures, page 38-16
• Cloning Signatures, page 38-18
• Editing Signature Parameters (Tuning Signatures), page 38-19
Signatures Page
Use the Signatures page to display the signature summary table, in which you can add, edit, and delete
IPS signatures. From this page you can tune the active signature set in a policy by enabling or disabling
signatures. You can also use this page to unload signatures from the engine.
Tips
• Disabled signatures are shown with hash marks covering the table row. When you deploy the
configuration, disabled signatures are removed from the device. For more information, see Enabling
and Disabling Signatures, page 38-10.
• For many columns, you can right-click the column and edit the property directly. Your edits apply
to all rows that you have selected. If you select multiple rows, the options that you can select are
limited to those that are valid for all selected rows. The contents of the right-click menu differ based
on the cell that you right click. For more information on the available commands, see Signature
Shortcut Menu, page 38-7.
