The impact of the man in the middle threat on the GSM signal (Diagram1)

The man in the middle attack is defined as a professional hacking operation to eavesdrop or steal or destroy a data between two destinations or more. This character of attack needs to special equipment depending on the type and method of the attack operation. This threat is considered one of the common threat operations that targeting the telecommunication systems frequently. The following diagram aims to illustrate how to intercepting the GSM signals between two points and receiving it from GSM relay tower that receiving a signal from point A and resending it to point B. The spy attempts to get these signals by a fixed or portable antenna, then decoding it by a specialized equipment for reaching to the data.

WHAT IS THE CYBER SECURITY !!!!?

Cyber security is the mode of defending computers, servers, mobile devices, electronic systems, networks, and data from hacker attacks. (What is Cyber Security?, 2020) we can be divided the cyber security into a few common categories: 1) Network security. 2)Application security. 3)Information security. 4)Operational security. 5)Disaster recovery and business continuity. 6)End-user education. (What is Cyber Security?, 2020) An essential job in cyber security is protecting kinds of technology devices and Sensitive data from hacker attacks. (Taylor, H. 2020) These attacks impact on a different variety of users, whether if they are governments, individuals, institutions, banks, universities, Etc The methods of hacker attacks consist of many technical tools, these technical are developing rapidly to stay invisible and penetrate through the protective technical walls to harm or steal the personal data. (Taylor, H. 2020) The following types show the popular methods using b...

Questionnaire- the impact of jamming and fraud threats on GSM system.

In accordance with the questionnaire, 57.1% of the participants have exposed to jamming operations while they were calling with other parties by the GSM system. Also, 81.8% of them have faced fraud calls from unknown individuals. This attack is called a phishing threat which asks the victim to share his personal information such as bank details, user names, passwords or other things that related to the victim with the hacker either by text message or phone call.

SOFTWARE EXAMPLE(CISCO PACKET TRACER)

I will illustrate how can we create a simultaneous GSM network by using Cisco Packet Tracer. In the begging, I create a surveillance office, then connect them together as a network with different IP by switch device, which is also linked to the central office server. After that, I use 3 relay towers and link them to the central office server. The following picture shows the destination of the call from smart devices to the telecom provider and opposite.
