The most important topic of today’s world as the whole world in some or other
way is connected through networks.Securing the internet has become an
important task in today’s world.But this is not an easy way to go it has many
precautions as many “HACKERS” are there around the world.The people who
are in the networks are “Vulnerable” as they are those people who need
security but here security in network.
Many things are done to make our
network secure but sometimes it fails and our most important data is also lost
this has to be stopped.
IP V 6 is the newest thing that is going to be
implemented to secure the network as in IP V6 the security level is much high as
it is said that it is impossible to hack the IP V6 address.
”FIREWALL” is also one of
the most important thing that we use to secure the network.As firewall is an
software but it is an hardware to which are used to secure the internet
network.
To protect our database it is very important to protect our network
because a very silly mistake can cause us a loss of huge amount and even our
very important database. It is totally impossible to create 100% foolproof
firewall or network without compromising the services that network has offer
being aware and regularly updating one, network in tune with latest updating in
field of computer security, is one trick that internet user must have in his or her
armory of defense against computer infiltration. Network security is a
complicated subject, historically only tackled by well-trained and experienced
experts.
However, as more and more people become “wired'', an increasing
number of people need to understand the basics of security in a networked
world. It explains the concepts needed to read through the hype in the
marketplace and understand risks and how to deal with them.
We go on to
consider risk management, network threats, firewalls, and more special-
purpose secure networking devices. The darkness of network field is an
unimaginable. For example whenever you connect to your internet, you provide
Gateway to the hackers who are willing to enter your machine thus whenever
you connect to internet your machine is not secure at all.
Now the big question
is how to provide protection to your machine and secure our data and
information, the only answer is Network Security.
