**S.N.O. Protocol Type** & **Examining Major Issues, Vulnerabilities and System Security** \\ \hline \multirow{8}{*}{1} & \multirow{8}{*}{Bluetooth} & \multirow{8}{*}{Blue jacking: Blue jacking typically involves hijacking another device’s Bluetooth to send unsolicited messages, including business cards, advertisements, and pictures. Blue jacking usually happens within a 10-m range for smartphones or up to 100 m for laptops. \\  & & Blue bugging: Blue bugging is when the hacker uses a Bluetooth connection to install malware on the target device. This malware gives the hacker a backdoor to the target device, allowing them complete control of the device. For example, the attacker may be able to eavesdrop or initiate phone calls, access contact information, and read and send messages. \\  & & Physical Attack: Zig-Bee network has a big weakness that all passwords are stored in memory without encryption. \\  & & Therefore, if an intruder gains physical access to the device, he will be able to find the key by copying the information in the device’s memory to the computer. (The location of the key is always in the same chip). \\
2 & Zig-Bee & * Therefore, to prevent this attack, all devices must be placed in a tamper-proof box, and if a violation is registered, the device must delete its memory [118]. \\  & & Key Attacks. \\  & & Replay Attacks: Secure networks always use trusted centers to keep their keys safe and multiple keys instead of one to protect against this attack [119]. \\  & & & Spoofing Attacks: Some of the challenges of spoofing attacks include the following: Transmission of false information in the IoT system, the vulnerability of IoT devices, endangering the decision-making process [120]. \\  & & & Discover and create an external topology. \\  & & & Arbitrary SR cache modification. \\  & & & WEP (Wired Equivalent privacy) and Wi-Fi protected access (WPA) can cracked in minutes. \\
4 & Wi-Fi & * WPA2 can also be cracked, only if user did not set it \\  & & & up properly. \\  & & & Problem with gate compromise. \\  & & & Physical device attack. \\
5 & LoraWAN & * Problems with encryption keys. \\  & & & Existence of non-optimal encryption methods. \\  & & & This technology is vulnerable to information disclosure and spoofing attack. \\
6 & 5G & * Heavy network traffic. \\  & & & Security issues of radio interfaces. \\
7 & 6 LoWPAN & * Transport layer security constraints. \\  & & & Security issues with datagram transport layer security. \\ \hline \hline \end{tabular}
