I have 2 questions. One of the IDS system has 2 interfaces.

1. Is there any advantage by setting the sniffing interface (without IP address)
   with NOARP and PROMISC settings?

2. With NOARP set, the system interfaces would not be broadcasting it's ARP
   addresses, so wouldn't this setting make that interface hard to spoof?
   (Please correct me if I am wrong here)

Thank you for any info.
