Title : Rapid Rogue Wireless Access Point Detection via RIPPS
Date : March 25, 2008. (3:30 pm) Tea starts half an hour before each seminar
Location: ITEB 336
Speaker : Prof. Aaron Striegel
Abstract:
Wireless network access has become an integral part of computing both at home and at the workplace. The convenience of wireless network access at work may be extremely beneficial to employees, but can be a burden to network security personnel. This burden is magnified by the threat of inexpensive wireless access points being installed in a network without the knowledge of network administrators. These devices, termed Rogue Wireless Access Points, may allow a malicious outsider to access valuable network resources, including confidential communications and other stored data. For this reason, wireless connectivity detection is an essential capability, but remains a difficult problem.
Our work on RIPPS (Rogue Identifying Packet Payload Slicing) tool is based on the following premise: is it possible to detect wireless connectivity for the purpose of detecting rogue WAPs (RWAPs) simply and inexpensively through in-network traffic characteristics at the edge of the network without end host modifications? Put simply, can one create a firewall-like device at the network edge that detects illegal wireless connectivity within milliseconds of usage? In this talk, I will present RIPPS and discuss how a novel packet payload slicing technique is used to rapidly identify the physical transmission media together with conditioning network traffic to enhance the accuracy of the detection. I will present the results of detailed experimental studies validating the effectiveness of RIPPS across a wide variety of configurations (OS, wireless speeds, network congestion, etc.).
