To Conclude

---

Network security is the way that a network can be
protected from misuse, malware, illegal access, and modification,
or any other unethical action to it. In the coming future, the IoT
or the Internet of Things are going to be the next big thing, and
so the network vulnerabilities are to be expected to rise at a
large number. So the protection of the networks is a must to think
as soon as possible. When the network is stronger, the victims of
data-theft are less. This is how all the networks can be brought in
a safe and sound environment. You can enroll in any of these
Network Security and cloud security Courses^[28] to know the importance
of protecting your network when it comes to safeguarding your
digital assets.
