Explanation
TCP/UDP port 5060 is commonly used by VoIP phones. It is the default port for SIP (Session Initiation Protocol), which is a signaling protocol that establishes, modifies, and terminates multimedia sessions over IP networks. SIP is widely used for VoIP applications such as voice and video calls. References:

Explanation
The output is most likely an example of an ARP poisoning attack. ARP poisoning, also known as ARP spoofing, is a type of attack that exploits the ARP protocol to associate a malicious device's MAC address with a legitimate IP address on a local area network. This allows the attacker to intercept, modify, or redirect network traffic between two devices without their knowledge. The output shows that there are multiple entries for the same IP address (192.168.1.1) with different MAC addresses in the ARP cache of the device. This indicates that an attacker has sent fake ARP replies to trick the device into believing that its MAC address is associated with the IP address of another device (such as the default gateway).

Explanation
itter is the variation in latency or delay of packets in a network. Satellite WAN links have high latency and are prone to jitter, which can affect the quality of voice and video applications. Jitter is the greatest concern for this type of connection

Explanation
SNMPv3 is a protocol that offers device monitoring using authentication and encryption. SNMP stands for Simple Network Management Protocol, and it is a standard way of collecting and organizing information about network devices, such as routers, switches, servers, printers, and so on. SNMPv3 is the latest version of SNMP, and it provides enhanced security features, such as data integrity, data origin authentication, data confidentiality, and access control. SNMPv3 can use different algorithms to encrypt and authenticate the communication between the network management system and the network devices12.
