    I think if you were watching in real time, a protocol analyzer would be best, but this is referencing something that happened prior (reviewing monthly usage). I would guess that A: Firewall Logs would be most appropriate. The usage doesn’t fall within the “Acceptable Use Policy” however I don’t believe it would be logged by the IDS unless the IDS thought the traffic was an intrusion. The Firewall, would log it all.

    This: https://www.sans.org/reading-room/whitepapers/firewalls/firewall-logs-811 has some good info on firewalls.
