Exploring network-based attacks

Threat actors such as hackers always look for security vulnerabilities in the systems and networks of their targets. A seasoned hacker will attempt to compromise the low-hanging fruits, as these are the security flaws that are easy to exploit on a system and do not require too much complexity in setting up the attack. Quite often, many people think security vulnerabilities are found only on applications and operating systems, but not on the network and its protocols. In the early days of the internet, many networking protocols were not designed with security features since it was not a concern as it is in today’s world. Many of these unsecure network protocols make up the Transmission Control Protocol/Internet Protocol (TCP/IP) networking model, which is implemented on every device that’s connected to a network. Therefore, the TCP/IP networking model contains a lot of vulnerabilities that can easily be exploited by hackers on a network...
