2. INTRODUCTION
Cybersecurity refers to a set of techniques used to
protect the integrity of networks, programs and data
from attack, damage or unauthorized access.
Three main aspects we are trying to control,
namely:
Unauthorized Access
Unauthorized Deletion
Unauthorized Modification
3. The CIA triad- is also commonly referred to as the
three pillars of security and most of the security
policies of an organization are built on these three
principles.
1. Confidentiality- the protection of personal
information.
2.Integrity- refers to methods of ensuring that data is
real, accurate and safeguarded from unauthorized
user modification.
3.Availability- refers to the ability of a user to
access information or resources in a specified
location and in the correct format.
4. HISTORY
Cybersecurity began in the 1970s when researcher Bob Thomas created
a computer programme called Creeper that could move across
ARPANET’s network.
1970- a number of security measures were developed, including
encryption algorithms, firewalls, and access control systems. The
development of the internet in the 1990s led to the creation of new
security protocols, such as the Secure Sockets Layer (SSL) and
Transport Layer Security (TLS), which are used to secure online
communications and transactions.
early 2000's- a number of high-profile cyberattacks, such as the Code
Red and Nimda worms, highlighted the growing threat of cybercrime.
5. HISTORY
Cybersecurity has been developed and advanced by a range of
individuals and organizations over time. It is difficult to attribute the
development of cybersecurity to any one person or group, as it has
evolved as a response to the changing threat landscape and the growth of
computer networks.

6. HISTORY
Where did cybersecurity begin?
Cyber magazine takes a look at the history of cybersecurity from inception
to the present day.
Cybersecurity is becoming increasingly significant due to the increased
reliance on computer systems, the Internet and wireless network standards
such as Bluetooth and Wi-Fi, and due to the growth of smart devices and
the various devices that constitute the ‘Internet of things’.
1970s: ARAPNET and the Creeper
Cybersecurity began in the 1970s when researcher Bob Thomas created a computer
programme called Creeper that could move across ARPANET’s network, leaving a
breadcrumb trail wherever it went. Ray Tomlinson, the inventor of email, wrote the
programme Reaper, which chased and deleted Creeper.
7. HISTORY
1980s: Birth of the commercial antivirus
1987 was the birth year of commercial antivirus although there were competing
claims for the innovator of the first antivirus product. Andreas Lüning and Kai Figge
released their first antivirus product for the Atari ST – which also saw the release of
Ultimate Virus Killer in 1987. Three Czechoslovakians created the first version of
the NOD antivirus in the same year and in the US, John McAfee founded McAfee
and released VirusScan.
1990s: The world goes online
With the internet becoming available to the public, more people began putting their
personal information online. Organised crime entities saw this as a potential source
of revenue and started to steal data from people and governments via the web. By the
middle of the 1990s, network security threats had increased exponentially and
firewalls and antivirus programmes had to be produced on a mass basis to protect the
public.
8. HISTORY
2000s: Threats diversify and multiply
In the early 2000s crime organisations started to heavily fund
professional cyberattacks and governments began to clamp down on the
criminality of hacking, giving much more serious sentences to those
culpable. Information security continued to advance as the internet grew
as well but, unfortunately, so did viruses.
2021: The next generation
The cybersecurity industry is continuing to grow at the speed of light.
The global cybersecurity market size is forecast to grow to $345.4bn by
2026 according to Statista. Ransomware is one of the most common
threats to any organisation's data security and is forecast to continue to
increase.
9. DEFINITION
Cyber security is the application of
technologies, processes, and controls to
protect systems, networks, programs, devices
and data from cyber attacks.
5 types of cyber security:
1. Critical infrastructure cyber security
2. Network security
3. Cloud security
4. IoT (Internet of Things) security
5. Application security
10. DEFINITION
1. Critical infrastructure cyber security
-Critical infrastructure organisations are often more vulnerable to attack
than others because SCADA (supervisory control and data acquisition)
systems often rely on older software.
2. Network security
-Network security involves addressing vulnerabilities affecting your
operating systems and network architecture, including servers and hosts,
firewalls and wireless access points, and network protocols.
3. Cloud security
-Cloud security is concerned with securing data, applications, and
infrastructure in the Cloud.
11. DEFINITION
4. IoT (Internet of Things) security
-IoT security involves securing smart devices and networks
connected to the IoT. IoT devices include things that connect
to the Internet without human intervention, such as smart fire
alarms, lights, thermostats, and other appliances.
5. Application security
-Application security involves addressing vulnerabilities
resulting from insecure development processes in designing,
coding, and publishing software or a website.
12. EXAMPLES: LATEST TRENDS
Examples of Network Security includes:
• Antivirus and Antispyware programs,
• Firewall that block unauthorized
access to a network and
• VPNs (Virtual Private Networks) used
for secure
13. EXAMPLES: LATEST TRENDS
Latest Trends:
1. Rise of Automotive Hacking
2. Potential of Artificial Intelligence (AI)
3. Mobile is the New Target
4. Cloud is Also Potentially Vulnerable
5. Data Breaches: Prime target
6. IoT with 5G Network: The New Era of
Technology and Risks
7. Automation and Integration
8. Targeted Ransomware

20. SUMMARY
Over the years, the term Cyber Security has gained much
importance and become a common part of each one’s life who is associated
with a computer or a smartphone device. When people submit their data
online, it becomes vulnerable to cyber-attacks or cyber-crimes.
Moreover, cyber-attacks can happen over an external facing DNS
server or an internal firewall, which in turn effects the data and
infrastructure within the enterprise that inherently causes significant
damage to the business of the associated organization.
Cyber Security offers security, from unauthorized access or
exploitation, through online services to the massive data, associated
appliances and network that is used for communication.
21. CONCLUSION
In conclusion, information is a critical part of any
organization and investing on the right service provider keeps your
business in safe hands in the ever-expanding IoT (Internet of Things)
world.
A scalable and customized cyber security-driven business
model includes disaster-recovery capabilities and secures data and the
underlying infrastructure of the organization, thus building a safe
barrier for the information even before it is attacked and saving the
organization from a loss of billions of dollars that could result from
the security threat.
