End users face common cybersecurity threats such as phishing attacks, ransomware, password reuse, using unpatched devices, lack of remote security, data leakage via social media, and disabling security controls. Key security measures for end users include setting administrator privileges, downloading and installing security updates, installing antivirus software, activating firewalls, using multi-factor authentication, and creating regular backups. Security awareness is important for end users to avoid risks to company assets from security lapses.

OVERVIEW
Security awareness should be a priority for any end-user. Lack of awareness or small errors can mean serious risk
to security, detrimental to company assets. End users tend to make or break security efforts.
Avoiding the most common security threats should always be a priority for modern-day infrastructural engineers
because you are implicitly aiding a criminal if you don’t even lock your front doors rigorously.
In this article, we will be sharing the most common threats that can be posed to an entity.
This e-book is entailed to identify the latest, most common cyber threats to end-users because of their lack of cyber-
security awareness. Also, recommended security measures that should be implemented to avoid such attacks to
computer systems.

THREATS

5. /4
PHISHING ATTACKS
Workplace and personal email become problematic when opening
malicious messages such as attachments, clicking embedded links,
enabling macros or replying to the sender.
Phishing messages are mass distributed via compromised email
accounts or mail servers. Spear phishing attacks are targeted phishing
attacks. This is where spear phishers use social engineering techniques
to personalise the phishing email.
The goals of phishing messages are to reveal confidential information
(passwords, bank details) and to install malware (e.g keystroke logger,
ransomware).

6. /5
RAN$OMWARE
Ransomware restricts access to your computer system
and demands a ransom to be paid in order for the
restriction to be removed. (e.g WannaCry)
Assets affected by ransomware within an organisation
include the organisation’s data because ransomware can
encrypt important files like, customer data, source code,
accounting or other confidential information.
Vulnerabilities can be exploited in several ways to enable
Ransomware to enter to computer system including
through social engineering. This can be through phishing
emails, suspicious websites, bad or essentially free
software from unknown sites, malicious advertising.

7. /6
PASSWORD REUSE
Using the same password for multiple accounts can compromise all accounts if only one account is
comprised. This can include social networking, emails, online banking.
Each account should have unique and lengthy password to reduce security risks. Strong passwords contain
a combination of numbers, special characters, lowercase and uppercase letters.

8. /7
USING UNPATCHED OR
POORLY CONFIGURED DEVICES (BYOD)
Organisations should always ensure that operating systems and software are updated with the latest
security patches. And you should not be running an outdated OS such as Windows XP, which is no longer
patched.
Attackers would attempt to exploit known vulnerabilities on unpatched devices. Therefore, performing
application and system updates/patching frequently addresses these known vulnerabilities.

9. /8
LACK OF REMOTE SECURITY
End-users often transfer files between their personal and work devices or allow their family members to
use their work devices at home, and this can create some security risks such as data misuse.
The fix is simple: the enforcement of a company-wide policy prohibiting the transfer of data from corporate
devices to personal ones.

10. /9
DATA LEAKAGE VIA SOCIAL
NETWORKING
Social engineers regularly review social media sites
and gather information on individuals and groups to
target in attacks.
Moreover, risks to confidential information getting
leaked/posted on networking websites which can
tarnish reputations.
For this reason, it is important to limit what you
share about yourself and others. For example, none
of your answers to security challenge question.

11. /10
DISABLED SECURITY CONTROLS
Administrators often disable security controls to make applications more usable for other users but, risks
to unauthorized application installation/usage can occur. Some users do not verify the authenticity of a
third-party application. This can lead to a small program taking control of the whole computer once
administrative privilege have been granted to approve the installation. Also, administrators have access to
confidential data that wouldn’t want to get into the wrong hands.

SET ADMINISTRATOR
PRIVILEGES
Revoking administrative access for unauthorisedend-users andonly granting access tothe localoperating
system and applications can prevent unauthorised changes to the system. Always follow the principle of
least privilege while assigning permissions.
An important precaution is to set a strong administrator password on your computer to avoid exploitation
to brute force attacks and multiple malwares that needs administrative access to install and can stop
many exploits since they do not have the permissions needed to compromise the system.

14. /13
DOWNLOAD & INSTALL ALL
SECURITY UPDATES
Windows 10 - automatically checks for the latest
updates.
Windows 7/8 – Open the Start menu and choose
Windows Update or configure your computer to
check for updates automatically.
Mac OS X 10.11.6 or higher - To check for updates,
open the App Store on your Mac and click Updates in
the toolbar.
Security updates should be applied to all third-party
software. These can include Flash, Adobe Reader,
Google Chrome, etc.

15. /14
INSTALL AND RUN
ANTI-VIRUS/SPY SOFTWARE
Spyware is malicious software that tracks
your computer activity, collects your
personal information, and degrades your
system's performance. Therefore, a key
layer of protection for your computer is
antivirus and anti-spyware software.
Many anti-virus software’s have free
versions but come with their restrictions.
Once you have installed this software, be
sure to update each with the latest
definitions immediately, then run a full
system scan.

16. /15
ACTIVE BUILT-IN FIREWALL
This can be fixed by installing a thick layer of firewall security measures and ensuring that nothing
unwanted passes through. This way, even if an employee is about to install a malware, they will be
restricted/blocked by the firewall, warned and the attempt is logged.

17. /16
MULTI-FACTOR AUTHENTICATION
Multi-Factor Authentication (MFA) adds a second layer of security to help prevent anyone other than you
from accessing your sensitive information online.
It combines two or more independent credentials: what the user knows (password), what the user has
(security token) and what the user is (biometric verification).
The goal of MFA is to create a layered defence and make it more difficult for an unauthorized person to
access. If single-factor or two-factor is compromised or broken, the attacker still has at least one more
barrier to breach before successfully breaking into the target.

18. /17
CREATE BACKUPS
Preserve your important files and the time it
took you to create them by saving backup
copies on a weekly basis.
You can back up data to external hard drives
or cloud storage services.
It is also a good idea to keep your original
operating system and software start-up disks
on hand in case your computer files get
damaged.
Back-ups are vital if a system crash or hard
drive failure occurs.
