In the last lecture, we talked about the definition of cybersecurity, now let's have a look at the
different types of cybersecurity.
Well, what is network security to force type is network security.
We all use Internet today, right?
Even if you are watching this online course using the Internet, Internet works as a network of four
different protocols.
It is a combination of small networks and everything in order to protect the network from cyber attacks.
Network security is the picture.
So network security, compromises of different security protocols like the IP protocol, which is very
common, it again makes use of encryption and decryption.
That is the cryptography, digital certificates, user account management, SSL protocol, beardless
weapons.
All this comes on network security.
So the domain which looks after the security of networks, is known as network security nexus application
security.
Now many people, including us, use different applications.
You use mobile applications, you use different apps, whether it is Mac or Mac OS or Android, whether
it is Windows application or, you know, device.
So every application also needs to be secure.
If you're using an e-learning app, that e-learning app is going to store your data.
So in order to protect that data, the application must be protected.
So application security basically deals with all the factors that are required for an application to
be completely secure and which can help to secure the data of people or the users next system security,
which is like operating systems or firewalls or antivirus.
Now, many of the employees will have a great amount of network and different operating systems in their
own companies.
In order to protect those laptops or protect those devices systems, security is used physical security,
as we had already discussed in the last couple of lectures.
Physical security deals with checking if a security guard is in place or other data centers properly
protected, is access controlled mechanism properly installed?
Are the clean desk and clean clear screen policies being implemented in the organization.
So all this comes under the domain of physical security.
Next is personal security.
But in identity access, management is one of the major areas in the picture.
So whether the employees are using the systems properly, if, if, if they are using properly, what
is the password management policy?
How well is the account of the users being managed?
This comes on a deep personal security organization and security so in which business continuity management
is one of the important factors, how organization is trying to protect its asset, whether the regular
audits are being carried out, in what way the organization is implementing the security controls.
All these questions are answered in organizational security, then comes to your development.
Now, this practice has been recently gained momentum because what developers earlier used to do is
they just used to develop a random software using the code.
But, you know, again, the code has to go through the quality checking process, the testing process,
again, alter the code to make it more secure.
So this a secure code development makes the code more secure right from the beginning.
So secure code development is therefore directly related to the application security here.
And last is cloud security, we all know that cloud has gained momentum in the last decade.
So cloud security is very important because most of the people have now started saving their documents,
their data, their photos or videos, everything on cloud.
So that cloud must also be protected.
Right.
That is why Google Drive, as your Amazon Web services have large teams of professionals in the cloud
development model to specifically secure the cloud.
Now, these are just the types which I've just told you as a basic introduction.
But again, there are many other types of securities.
For example, App Asset Security, Asset Management, again, financial security, monitoring, security.
So all these securities are also in the picture.
But for discourse, you just need to have the basic idea of these types of security.
Greed in the next lecture will go through the history of cybersecurity, will understand how this cybersecurity
world was formed and when exactly did it start to, you know, have the security need for organizations
right now.
Great.
Keep the momentum going.
I will see you in the next lecture.
