Great, let us get started with the next section, and in the first lecture, we're going to talk about
the basic definition of cybersecurity.
Cybersecurity is the practice of defending computers, servers, mobile devices, electronic systems,
networks and data from malicious attacks that often hackers are trying to breach.
It's also known as information technology, security or electronic information security.
Again, this term of cybersecurity applies in a variety of contacts from business to mobile computing,
and it can be divided into a few common categories like network security, application, security,
information security, operational security, disaster recovery and business continuity and user education.
Now, as I said, the global threat continues to evolve at a rapid pace with the rising number of data
breaches per year.
Now, medical devices, retailers and even public entities are experienced cyber attacks.
And that is why we need cybersecurity.
On other alternate definition of cybersecurity can be.
It is the application of technologies, processes and controls to protect the systems, networks, programs,
devices and data from cyberattacks.
It's like protecting something from something.
So cybersecurity is protection of computer systems, of hardware from malicious attacks.
Not people often get confused with information security and cybersecurity because they think that both
these terms are exactly the same.
Well, today, I would like to tell you that these items are not at all seem.
Cybersecurity focuses on protecting the computer systems from unauthorized access, whereas information
security is a broader category that looks to protect all the information assets.
It can be digital copies of something that's a video, lectures or documents.
It can be human resources.
It can be monetary assets.
It can be the employee's identity.
It can be physical security.
So everything that is under falls under the category of information security.
So we can see that cybersecurity is a part of information security, but information security is a much
broader category.
So if anyone asks you the difference between a cybersecurity and information security, make sure that
you understand this difference properly.
And due to the rise of information security, cybersecurity is also on the front line.
So to have a quick recap of this lecture, cyber security is basically the application of technologies
to defend the computer systems.
It can be servers.
They can be mobile electronic devices like your own laptop, your company's laptop or your own mobile
from the malicious attacks.
And information security is a much broader category.
So this is the difference and this is the basic definition of cybersecurity, which you can see on the
screen.
Great, I hope you have understood the definition of cybersecurity, if you still have any doubts,
please feel free to ask us in the Q&A portion in the next lecture.
We are going to talk about the different types of cybersecurity in the first one, which is going to
be the network security.
