Let's begin with cyber security.
In this module of fundamentals of cyber security, we will see what is the definition of security.
We will also see the importance of cyber security and why do we need security in our day to day life.
So let us begin.
So why do we need security?
But before that, what is security?
In today's world, security has become a challenging task.
Security mostly refers to the protection from hostile forces, but it has a wide range of other cancers.
Every individual is concerned about his privacy due to the rapid growth in the information technology
industry, the need for security is also increasing.
Security also refers to the measures that are taken to protect a place or to ensure that only people
with permission can enter it or access it.
So what do you like your friends to have access to your mobile?
The clear answer is no.
And that is what you have set a password to your mobile, which is just known to you.
Also, do you want your data to be protected against security attacks and here the obvious answer is
yes.
You don't want a stranger or an intruder to have access to data or he or she might targeting.
The next question is, do we really need cyber security?
OK, so let's face it, we live in a digital world.
Our work lives, personal lives and finances have all begin gravitating towards the world of Internet,
mobile computing and electronic media.
Wide use of the Internet has increased the cyber crimes exponentially.
Unfortunately, this widespread use makes us more vulnerable than ever to malicious attacks, invasions
of privacy, fraud and other such complications.
And that is why cyber security is such a vital part of secure and well-ordered digital world.
Risk based security, a cyber security firm revealed that shocking seven point nine billion records
have been exposed by data breaches.
Well, your record could be one of them, right?
Have you ever thought of that?
And that is why we need cyber security to keep confidential data secure.
Cybersecurity ventures, another cybersecurity firm, predicted that in 2017, the damages would hit
six trillion dollars by 2021 and 10 trillion dollars by 2030.
Isn't that a massive amount?
Right, the main aim or the main motive of these attacks is to affect financial sectors and health care
sectors.
Now let us see the different types of computer security.
There are various types, numerous types of security force being the network security, it is the practice
of securing a computer network from intruders with the targeted attackers or opportunistic malicious
network engineers.
Network administrators look into this security part.
Next comes information security.
It protects the integrity and privacy of your data, your messages, your videos, your photos and ET.
The most important is the application security, if the application is not secure, how would it prevent
the loss of information?
So application security focuses on keeping software devices free of threats before an application is
deployed onto the Internet or in Plaistow or in App Store.
It first has to pass the application security check.
Then comes a disaster recovery and business continuity.
It defines how an organization should react or respond to a cybersecurity incident or any event that
causes the loss of operations.
They say that experience is the best teacher and this is get to disaster recovery team.
They always learn from the past cybersecurity attacks.
So let us have a quick recap.
We saw the definition of security, then we saw why do we need security?
And we discussed how security is affecting the economy of countries.
And they finally concluded our section with different types of computer security in the next lecture
will see the exact definition of cyber security by various different organizations and standards.
