Hello everybody and welcome to this introductory video. Today, I will be
talking about ethical hacking, and I will also introduce you to the course itself.
So, first off, you might have noticed that the term ethical hacking is composed
out of two words. You have ethical and you have hacking. Now hacking, the
definition of hacking, is quite broad. I mean it encompasses a very wide range of
activities. However, if you actually go to any of the online dictionaries pretty
much, and if you type in the term hacking, generally it will say that it has
something to do with computers. I cannot say that it's not true, however that is
only a small portion of the definition. Rather, instead, the act of hacking is
actually having any system, and I mean any system, not just a computer system,
not just a digital system, in fact the system doesn't even need to
contain any electronic parts, so literally any system, having it do
something that you intended it to do, as opposed to what it was designed to do.
Now here is one short example that has been cited over and over again. You have
a lock, basically, have a door lock in your house. Everybody has one. Well, I
sincerely hope that you have one. And the purpose of that lock is
to prevent intruders from entering. So anybody who does not have a
key cannot enter. But, people people enter without a key anyway
because they pick the lock, and then they enter. And that itself could be
considered an act of hacking. Also an act of burglary, but that's
another subject. Anyway, the ethical side of it would be when you
have these large automobile industry manufacturers, and then they hire people,
they hire these burglars, to come and pentest their locks. So, basically, they
pay them very good sums of money to go to their factories and to try to
unlock their cars. This doesn't need to apply only to locks for cars. It can also
apply for your door locks. Manufacturers have pretty much all sorts of locks they
hire people to actually try and pick lock them, and then if they succeed doing
it, and if they succeed they pay them a very good sum of money. I do believe that
prices for one car manufacturer they went up to 1 million euros, if you
managed to break their locks. But, what I'm trying to say here is that
the ethical side of it would be when you have a permission to do it, when it's
within the constraints of the law. And the act of hacking itself can be within
the constraints of the law, but doesn't necessarily need to be. Anyway, we will
not be focusing on those types of locks today, or during this course. During this
course I will teach you how to penetrate networks, how to exploit systems, how to
break into computers, how to compromise routers, etc. After
you've finished this course, after you've absorbed all the information in it, you
will gain the ability to do some serious damage. Now because of that I wish to
give a disclaimer here. So first off I do not encourage any sort of illegal
activity. Furthermore, I strongly advise against it, and I am against it. So you do
not have any legit need to do anything that is against the law with the
knowledge that you're gonna get during this course. Because you're gonna
get some pretty good knowledge, and you can abuse it very easily. It's not that
difficult to abuse it. The opportunities are everywhere, they're endless, because
people tend to use insecure systems, or they use secure systems but they don't
know how to operate or configure them. And then in turn those security systems
become insecure. But what I'm trying to tell you is there really is no need. I
mean if you want to do it for the money, or something like that, you can make the
same amount, if not more, in a perfectly legitimate way. People will pay you to
actually test their networks and to see if you can find any vulnerabilities in
them, and then report them, perhaps even fix them. So, however, if you do decide to
do something against the law in any country, I am NOT responsible for it.
That is what I want to say. I do not claim responsibility for it. As I
have already stated, I am doing this for purely educational purposes, and
I do not advocate the use of this material for any sort of illegal purpose.
Now I hope you understand why I had to make this disclaimer, and this is not
what I said, these are not just empty words, I really do stand by it, and that
is my philosophy as well. In any case, during this course I will
show you numerous examples, methods you will need some prerequisites over which
I will go in the next tutorial, but you're in for a ride. So sit down, be
patient, that is a very important thing in this line of work. Patience because
everybody out there, I mean if you are looking at this
tutorial now, if you've typed in the term ethical hacking, I'm guessing that you've
seen some, guessing at some point of time in your lives like myself you have seen
a movie that involves some sort of hacking with computers, and you see this
terminal, and just see them typing in something there, and
just basically works. It works within five minutes or something like that. Let
me tell you something, that has nothing to do with the
real world, or very little to do with the real world.
In the real world, people spend countless, sleepless life trying to do
something, trying to obtain access, trying to bypass a password-protected file, or
something of a kind, in a server, trying to escalate privileges, trying to inject
a sql injection, or something of a kind, and they not only spend countless
sleepless nights doing it, but they also spend a long time planning, preparing, and
getting a general idea of what they can do, how they can execute an attack, etc.
These are not things that you will be able to do within five minutes
after you sit and open up your desktop computer, or whatever. You
will need time, you will need patience, but above all you will need to be
curious. Curiosity is one of the first steps here, and obviously since
you've actually chosen to listen to this tutorial, to go through it, you do possess
it already. You just need to build on it a little bit more, and you will be where
you want to be. In any case, I hope to see you in the next tutorial and I bid you
farewell.
