Vulnerable network protocols and network intrusions

Networks, including the internet, were established at a time when there were hardly any cybersecurity threats aimed at them. Therefore, a lot of focus was given to aspects such as performance and speed. Since there was no security design during the establishment of early networks, several adoptions have had to be incorporated due to shifts such as increased cybersecurity threats. However, this is becoming a catch-up game and hackers are unfortunately growing more powerful. This has seen several vulnerabilities being discovered in network protocols. The following are some internet protocols that are increasingly becoming insecure.
