The usage of Network Address Translation (NAT) and/or Network Proxy systems is very common among thex000D
devices such as computers, laptops and smart phones connecting to the Internet. These systems act as an agentx000D
between the Internet and a private network, e.g. user's local area network. This means that only a single IPx000D
address is required to represent one or more computers (users) to the rest of the Internet. Thus, NATs/Proxiesx000D
are used for many reasons including a solution to the shortage of IPv4 addresses, security, or anonymity. In thisx000D
research, our goal is to explore whether we can find specific patterns in the network traffic that will enable usx000D
to identify NAT/Proxy like behaviors and the different users and services behind them. In doing so, we aim tox000D
differentiate malicious usage of these systems from legitimate usage.
