The objects of forensic examination and research related to telecommunication systems (equipment) and means may be:
- Internet IP nodes;
- domain names, web pages, Internet addressing;
- radio transmitters;
- radio receivers;
- switching nodes;
- primary communication networks;
- satellite ground stations.
Forensic examinations in the field of telecommunication systems (equipment) and means are appointed when resolving the issue of:
- interference in the operation of telecommunications operator networks;
- substitution, distortion, leakage, loss of traffic and distortion of its processing process;
- violation of the established traffic routing order;
- Features of using domain names on the Internet.
When assigning expertise or ordering research of telecommunication systems (equipment) and facilities, the following materials must be provided:
- Appropriate materials containing information on the terms of cooperation (contract, agreement).
- Appropriate materials that contain information about the process.
- Other materials depending on the issues that are put to the expert’s decision.
The main tasks of the examination of telecommunication systems and facilities are:
- determination of characteristics and parameters of telecommunication systems and facilities;
- establishing facts and methods of transmitting (receiving) information in telecommunication systems;
- establishing facts and methods of access to systems, resources and information in the field of telecommunications;
- determining the quality of telecommunication services at the level of their consumption;
- establishing the configuration and operating status of telecommunication systems and facilities;
- establishing the type, brand, model and other classification categories of telecommunication systems and facilities;
- research into information processing algorithms and their protection in the field of telecommunications.
Indicative list of issues to be addressed:
- What is the type, brand, and model of the telecommunications equipment (system)?
- Is the telecommunications facility (object) in working condition?
- What network connection characteristics does a telecommunications device have?
- Did the user of the telecommunications network change the settings of individual devices, at what time, and what were their values?
- What is the general nature of the connections to the telecommunications network performed by the object (telecommunications system, facility)?
- What software was used to connect to the telecommunications network?
- What is the topology of the hardware combined into a telecommunications system?
- Does the functioning of the telecommunications facility (system) comply with the technical documentation?
- What technical characteristics (parameters) does a telecommunications device (system) have?
- Was there access to the telecommunications system and in what way?
- Was there any use of resources and information in the telecommunications system and in what way?
- Was there a fact of transmission (reception) of information in the telecommunications system and in what way?
- Are there any signs of interference in the telecommunications system?
- Could hardware be combined into a telecommunications network and on what basis?
- What are the data routing paths in a telecommunications system?
- Is it possible to use telecommunications equipment for the specified purposes?
