Computer network protocols define the rules in which two entities communicate over a
network of unique hosts. Many protocol specifications are unknown, unavailable, or …

Knowledge about a network protocol to understand the communication between entities is
necessary for vulnerability research, penetration testing, malware analysis, network …

Smartphone apps have changed the way we interact with online services, but highly
specialized apps come at a cost to privacy. In this paper we will demonstrate that a passive …

Network security products, such as NIDS or application firewalls, tend to focus on application
level communication flows. However, adding support for new proprietary and often …

Network protocol reverse engineering is an important challenge with many security
applications. A popular kind of method leverages network message traces. These methods …

Traffic classification, a mapping of traffic to network applications, is important for a variety of
networking and security issues, such as network measurement, network monitoring, as well …

A critical aspect of network management from an operator's perspective is the ability to
understand or classify all traffic that traverses the network. The failure of port based traffic …

The security of industrial control systems relies on the communication and data exchange
capabilities provided by industrial control protocols, which can be complex, and may even …

With many network protocols using obfuscation techniques to hide their identity, robust
methods of traffic classification are required. In traditional deep-packet-inspection (DPI) …

The widespread utilization of network protocols raises many security and privacy concerns.
To address them, protocol reverse-engineering (PRE) has been broadly applied in diverse …
