TASK
Common Risk on the overall security system of computers-
There are different types of common risk generated in the computer system effectively and
efficiently.
 Hackers- Hacker is basically person those who tries to crack the password of computer
system and also exploits the hardware for particular reasons. It is terminology that used in
the computer security and damage the personal information and company data. Hacker
will use the different software that access their entire processing in quickly. It is the most
common technique to lost the data anywhere.
 Unauthorized access- unauthorized access is the happen when someone can use the
server to access the details of particular website. In this way, it is also accessed the
sensitive data of another person. An organization is store the details of customers in their
official database (Papernot and et.al., 2018). In this way, An authorized person easily
access the personal information of client such as transaction details, account number, card
details etc. It affects the entire processing of organization and many times, the firms face
loss and challenges issues.
 Threats- It is the most common aspects of computer security that generated at any time
in the system. It mainly causes the serious damage in the hard ware that impact on the
overall operations and functions. Sometimes, threats may be affect or not because it
depends on the quality and accessibility. This is the important for people to always
protect their smartphone, tablet and PC to secure through threats. It is based on the action
and event that might happen in the computer system and it is also comprises the security
(Thota and et.al., 2018).
 Vulnerability- It is usually based on the weakness that help to exploit by the threats in
the entire system such as attackers, This is unauthorized persona that perform in the
different action in the other devices such as computer system, Smartphones and tablets
etc. The attacker will use the one tool or technique to connect with the system weakness

and damage their processing system (Roman, Lopez and Mambo, 2018). Security risk is
the classified on the basis of vulnerability because this concept is applicable in the system
that generate more risk on system. In this way, it directly connects with the weakness and
damage the entire process.
 Attack- It is the assault on the security system where the person can be delivered the
unwanted software and text message to the accounts. In this way, the person can open the
software that impact on the computer system. This is the way to attack the hardware and
other PC, smart phones and tablet etc. It is required for every user to check in properly.
Afterwards, install the app in the smartphone because there are various types of fake
application available in the marketplace. The only reason to affect the device of hardware
to the people. In this way, the attacker access all the personal information of users in
quick manner.
 Antivirus and Anti-malware- This is the software that help for providing the security
and operates the operating system of devices for preventing through the malicious
software. This is the important for user to always install the antivirus in the smart phones
because it can provide the security features and aspects to automatically control and
remove the unwanted software in the systems (Ross, McEvilley and Oren, 2018).
 Social engineering- It is based on the technique where the hacker can access and use the
stolen data of another person for the purpose of psychological manipulations. It is the
based on the large number of malicious activities that happen by the human interactions.
Sometimes, the people use the psychological manipulation and trick makes mistake or
giving away the personal and sensitive information. The attack can happen into more
steps that investigate to gather all necessary information therefore, Attacker moves to
gain the trust of user and provide the stimulation action that break all the security aspects
and practices like revealing and accessing all information and granting to the critical
resources.
 Virus- It is a type of malicious software that enter in the smartphone, tablets and
Computer system with the help of installation, unwanted application etc. These are
different sources that help for enter in the system. In this way, The entire system of
smartphone is slower. It also impacts on the overall efficiency and data processing. The
main purpose of malicious software to damage the smart phone operations and slow

down. It is required for user to use the security features that help for protecting the whole
system in effective manner (Thota and et.al., 2018).
Impact on the Normal Man

viruses and threats. In new phone, there are various types of features available in the phone that
set a passcode to lock the phone. It is the security option that applicable the different options
such as fingerprint, image recognition, Number-code etc. this features is added in the phone to
protect and secure in effective manner (Alali and et.al., 2018). Many new smartphone and tablet
offers different lock pattern and without the figure print, it cannot be possible to unlock the cell
phones.
Lock your app- Many organizations always remember to the security issue so that they
launch a smart phones which offers different features. In this way, it can be individually lock
installed application with the help of passcode and scan fingerprint. This features can extra
security layer to protect their data and important content especially when you hold the phone and
other person to show something. It also useful for person to install the features and applied the
smartphones such as App-lock etc.
Use two factor authentication- Many people can ignore the security features that face
many problems and hassle at every time that's why, it is required for user to use the two factor
authentication that help for provide the security with the help of authenticate with the passcode
(Conti and et.al., 2018). It can generate the unique authenticated code for particular application
such as One time password etc. this type of security feature offered by different services such as
Facebook, twitter, Instagram, google, Amazon, Snap-chat, PayPal etc.
Install security applications- A smart phone is based on the susceptible to data theft in
the computer system. It is important to get smart phones to install the security application that
manage the entire processing of system (Lee and et.al., 2018). There are various type of security
application available in the organization such as McAfee, Trend Micro, Avast, Norton etc. This

feature is automatically scan the smart phone and remove all unwanted threats and software in
the system.
