So let's get started.
The history of cybersecurity.
In this lecture, we learn how cybersecurity evolved when was the first cyber threat that occurred and
obviously the evolution of cybersecurity.
1980S was the era of computer worms, the creation of the first computer worm was a milestone in the
history of cybersecurity.
Researchers traced the very first disastrous computer worm to Robert Demorris, who was a graduate student
from Cornell University.
Morris was curious about the Internet's size and created a boom in 1988.
Gurjit.
The worm was designed to infect Unix systems such that it would count the total connections present
of a modest 021 program that would propagate across a set of networks, use a known vulnerability to
infiltrate Unix terminals and then replicate itself.
However, this turned out to be a huge mistake, a programming error because the worm to infect machine
after machine.
As a result, networks clogged, causing the connection systems to crash the worm, replicating aggressively
to a point where the indirect slowed down to a crawl, leaving untold damage in its wake.
This one is the first to have received full media coverage and was among the very first programs to
return to exploit system until Britta's.
The womb's effect lasted beyond the crash, Internet and connected systems, for one modest, became
the first person to be charged successfully under the Computer Fraud and Abuse Act.
He was fined ten thousand dollars and then sentenced to probation of three years and dismissed from
court, although he went on to become an MIT professor.
This act for the led to the development of computer emergency response team, that is so.
The modest one triggered the start of an entirely new field in computer security.
It led to more people researching on how they can create a deadlier and more effective bombs and viruses.
1990S was the era of viruses.
As previously mentioned, the models will pave the way for new types of malicious programs, viruses
were more aggressive programs that came into light in the 1990s.
Why does such as I Love You and Melissa infected tens of millions of computers, causing a worldwide
failure of immune systems, most of the virus attacks were primarily concerned with financial gains
or strategic objectives.
However, inadequate security solutions at that time caused a huge number of unintended victims to be
affected.
Suddenly, cyber threats and attacks were a huge concern, necessarily being the creations of an immediate
solution.
This problem gave birth to the antivirus software solutions, the programs were designed to detect the
presence of viruses and to prevent them from accomplishing that intended tasks.
The primary delivery method for virus was the use of malicious e-mail attachments, and therefore this
gave rise to the antivirus industry in the early 1990s, saw a sharp growth of companies creating and
retaining antivirus products.
The products were scanning computer systems for the presence of viruses or worms.
At the same time, the available and solution scanned business I.T. systems and tested them with signatures
written in a database.
All of these things we are going to study in the later part of this school's.
However, two significant problems had high impact and the effectiveness of these early antivirus solutions.
The issues persist today in some of the current cybersecurity solutions, the problems included, the
intensive use of resources are a large number of false positives and the former cause of most problems
for users since antivirus solutions scanning systems used a lot of available resources such that the
Internet user activities and productivity.
The endpoint protection platforms slowly proved to be a better security solutions for countering an
increasing rate of virus attacks.
Customers realized that it was possible to detect and stop unknown malware.
Since only a signature of the existing malware was required.
Then come the first hacker group.
What is a hacker group, it consists of individuals with exceptional hacking skills, but they use it
for unauthorized access and illegal activities.
Main purpose of such hacker group is the financial gain, and the money behind it will see the types
of hacking groups later in this course.
But your knowledge Anonymous was the first hacker group that came into the light on October one, 2003.
It first made news when it hacked a website belonging to the Church of Scientology to Deros attack.
And this is where hacking organization struck.
So we saw the history of cybersecurity, we saw how the first one started affecting the world and which
led to the development of many cyber security hacking organizations.
In the next lecture, you will see the scope and career of cybersecurity.
The next lecture is very important for you if you really want to create a nice and decent career in
cybersecurity.
