Importance of Cyber Security in Protecting Against Cyber Attacks

It is a very important to assure that nobody is trying to steal any type of data or else money
from any of the business activities that are moving online. For securing from these type of
threats it is very important to implement cyber security. Any type of unauthorised access or
any type of destruction that may happen to any of computer related equipment or networks,
cyber security acts in these purpose for protecting these systems. Cyber-attack can be of
different type that include theft as well as any type of unauthorised access to the computers or
to any such other devices. It also includes any type of remote attack which may happen on
various computer systems or else it can be on various websites and even it can be a third
party attack as on cloud devices. On a strike of cyber-attack it cause financial loss, the
recovery cost an even the replacement cost can be very high (Rid and Buchanan 2015). Even
the reputation of the company can go down and can also cause damage to any other
companies those are related to that company.
There are four types of attacks that generally occurs.
Denial of Service: This type of attacks creates damage generally to the computer networks or
else to the applications or to any systems and exhaust all the resources. Once this attack
happens to the systems, the hackers asks for an amount of money that is termed as ransom,
after which the access is given to the user.
Malware, Worms and Trojan horses: This type of attack happens on various websites those
are non-malicious, but after the attack the websites become malicious. This type of harmful
viruses are spread through emails, through various malicious websites or else through instant
message.
Botnets and zombies: In this case in the central controller which creates a robot network into
which a number of computers are connected. This type of computers are called zombies
botnets, these are made for stealing of data and it is also very difficult for detecting.

Scareware: These are the fake warning of security. This attacks are highly profitable for the
cyber criminals as because many of the users think these warnings to be real and thus follow
certain steps that are instructed regarding this threats.
This is an important factor for various companies in protecting themselves from any type of
scam threats, thief of data or else any type of other vulnerabilities. Planning is the only
solution from preventing this type of practises. In this planning it may include to know which
the information assets that are very critical and then to study that what will be exposed due to
this type of risks. The legal requirements and the compliance requirements are to be detected.
Implementing is another important factor that is to be noticed, such as what type of security
controls that is to be taken specifically for specific IT systems and all other outsource staffs
should know their responsibilities. After that also if any type of attack happens further, what
are the steps that is to be followed to protect their business from the attack.
Finally reviewing is an important factor that is always to be done. It is very important to test
the effectiveness of of the controls. Right after completion of monitoring any required actions
should be done regarding the problems monitored. Knowledge regarding the latest threats
should be kept into account. Thus by following all the above three process it will be easier to
counter any type of cyber-attacks.
In todays world computer is a part of human’s life. It is almost impossible to remove
computer from the life of people. The high rising technology made life much easier and helps
in connecting remotely through interconnected networks. There are certains ways through
which people are connected among themselves such as via smart devices etc. In these various

such as passwords, etc.
i. Let’s know more: In this case the victim is manipulated to perform various
unlawful tasks. This is termed as Social Engineering.
3. Organisations under cybercrimes: This type of attacks are highly planned and this acts
may cause huge amount of effect into the computer networks. Huge number of
civilians gets effected due this type of tasks.
a. Transmitting Virus: Computer virus is defined as a type of computer program or
else a number of computer programs that creates effect on a normal functioning
computer. This type of viruses generally effects or destroys the data. A type of
virus which is known as biological virus that enters to any of the computer system
without giving any type of notice to the user. Virus is illustrated as “Vital
Information Resources Under Seize”. Due to the spread of virus it affects the
processing speed of the computer system, hamper the programs, effect on data,
etc. The programs present in virus a self-replicating that expands automatically
and spread throughout the infected network and infects the data of the system,
files present in the system and all other types of effect. Making of the program of
the virus and implementing it into the network is a type of cybercrime. All of t6he
virus are to be executed. That when any virus is present in a computer system, it
will not affect the system until and unless the program is opened in the system.
