CAPEC-192: Protocol Analysis
Description
Extended Description
Although certain techniques for protocol analysis benefit from manipulating live 'on-the-wire' interactions between communicating components, static or dynamic analysis techniques applied to executables as well as to device drivers, such as network interface drivers, can also be used to reveal the function and characteristics of a communication protocol implementation. Depending upon the methods used the process may involve observing, interacting, and modifying actual communications occurring between hosts. The goal of protocol analysis is to derive the data transmission syntax, as well as to extract the meaningful content, including packet or content delimiters used by the protocol. This type of analysis is often performed on closed-specification protocols, or proprietary protocols, but is also useful for analyzing publicly available specifications to determine how particular implementations deviate from published specifications.

This table shows the other attack patterns and high level categories that are related to this attack pattern.
Prerequisites
This table shows the other attack patterns and high level categories that are related to this attack pattern.
- Access to a binary executable.
- The ability to observe and interact with a communication channel between communicating processes.
Skills required
This table shows the other attack patterns and high level categories that are related to this attack pattern.
- High Knowlegde of the Open Systems Interconnection model (OSI model), and famililarity with Wireshark or some other packet analyzer.
Taxonomy mappings
Mappings to ATT&CK, OWASP and other frameworks.
Resources required
Depending on the type of analysis, a variety of tools might be required, such as static code and/or dynamic analysis tools. Alternatively, the effort might require debugging programs such as ollydbg, SoftICE, or disassemblers like IDA Pro. In some instances, packet sniffing or packet analyzing programs such as TCP dump or Wireshark are necessary. Lastly, specific protocol analysis might require tools such as PDB (Protocol Debug), or packet injection tools like pcap or Nemesis.
