I am searching for a way that a systems administrator can locate/detect/identify unauthorized wireless access points in global (or WAN) network, including those across the oceans, even not being physically there!
One way is "war driving". However, it requires a person physically walking inside the organization or driving around the organization's campus with a "war driving" software.
Can one use a packet sniffer to find out APs? But it may be "blocked" by VLANs.
Any advice / pointers are appreciated.
Thanks and have a nice weekend.
