For Network IPS appliances,
poorly written rules or signatures
can affect sensor performance or have other consequences.
Using your own
custom signatures include, but are not limited to,
the following risks:
- Unacceptable appliance performance
- Causing
the appliance to go into an infinite loop
- Blocking all network
traffic to a specific segment (inline mode
with or without bypass)
- Reinstalling the factory image to
return to a "good" state
Attention: IBM® Support is not available to help write or
troubleshoot custom rules. If you need assistance with creating custom
signatures, contact IBM Professional
Services.
