Inferring the composition of devices behind a network address translation (NAT) router
August 4, 2021 @ 6:30 pm - 7:30 pm
One event on August 4, 2021 at 6:30 pm
(Hybrid – at venue and virtual seminar)
Network address translation (NAT) is an essential service for combating the shortage of IPv4 address space and is widely deployed within large enterprise to home networks. However, its ubiquitous use has introduced significant challenges into the management of devices on a network.
Device management is of critical importance to network administrators and security analysts alike to better manage and secure the devices operating on their networks. Techniques to perform device management in the presence of the NAT service are therefore essential. However, recent techniques that rely on network traffic payload content are no longer possible due to widespread encryption standards.
In this seminar, I will discuss a technique to estimate the number of devices acting behind a NAT router and the composition of their operating systems; through the exclusive analysis of the IP addresses the router affiliates with. The proposed technique is thus invariant to encryption, lightweight, and widely deployable to distinct network configurations.
