What is cybersecurity?
Cybersecurity is the practice of protecting internet-connected systems such as
hardware, software and data from cyberthreats. It's used by individuals and
enterprises to protect against unauthorized access to data centers and other
computerized systems.
An effective cybersecurity strategy can provide a strong security posture against
malicious attacks designed to access, alter, delete, destroy or extort an
organization's or user's systems and sensitive data. Cybersecurity is also
instrumental in preventing attacks designed to disable or disrupt a system's or
device's operations.
Why is Cybersecurity is Important?
Cyber Security is important because the government, corporations, and medical
organizations, collect military, financial, process, and store unprecedented
amounts of data on a computer and other properties like personal information,
and this private information exposure could have negative consequences.
In 1972, when the internet was just starting (called ARPANET at the time), a test
virus named Creeper was created—and then another program called Reaper was
made to remove it. This early experiment showed why digital security was
needed and helped start what we now call cybersecurity.

Cyberspace
Cyberspace is the digital realm where interactions occur via computers and
networks, and cyber threats are malicious acts aimed at damaging data, stealing
information, or disrupting digital systems. These threats can take various forms,
including malware, phishing, ransomware, and denial-of-service
attacks. Understanding these threats and implementing appropriate security
measures is crucial for protecting individuals and organizations in the digital age.
Cyber threats
Cyber threats are malicious activities aimed at compromising the security of digital
systems, networks, and data, potentially leading to data breaches, system damage,
and disruption. These threats can originate from various sources, including external
attackers, insider threats (e.g., malicious employees), and even unintentional
errors. Common examples include malware, phishing, ransomware, and social
engineering.
Cyber warfare
Cyber warfare involves using computers and networks to attack and potentially
damage another nation's systems. It can involve actions like espionage, sabotage,
and denial-of-service attacks, aiming to disrupt or weaken the target's
infrastructure.
Cyber warfare is a form of conflict that utilizes computer systems and networks to
carry out attacks or gain an advantage. It's often associated with nation-states but
can also involve other actors like terrorist organizations or hacking groups.
CIA Triad
The CIA Triad in information security represents three core
principles: Confidentiality, Integrity, and Availability. These principles are essential
for protecting information and ensuring its trustworthiness and usability.
The three letters in "CIA triad" stand for Confidentiality, Integrity, and
Availability. The CIA triad is a common model that forms the basis for the
development of security systems. They are used for finding vulnerabilities and
methods for creating solutions.
The confidentiality, integrity, and availability of information is crucial to the
operation of a business, and the CIA triad segments these three ideas into separate
focal points. This differentiation is helpful because it helps guide security teams as
they pinpoint the different ways in which they can address each concern.
Ideally, when all three standards have been met, the security profile of the
organization is stronger and better equipped to handle threat incidents.
Cyberterrorism
Cyberterrorism refers to the use of cyberspace and information technology to carry
out acts of terrorism, often involving attacks on critical infrastructure, data
networks, or communication systems to cause physical or psychological damage,
disrupt services, or coerce actions. It involves using computer systems and
networks to execute attacks, spread propaganda, or incite fear.
Cyberterrorism is the use of the Internet to conduct violent acts that result in, or
threaten, the loss of life or significant bodily harm, in order to achieve political or
ideological gains through threat or intimidation. Emerging alongside the
development of information technology,[1] cyberterrorism involves acts of
deliberate, large-scale disruption of computer networks, especially of personal
computers attached to the Internet by means of tools such as computer
viruses, computer worms, phishing, malicious software, hardware methods, and
programming scripts can all be forms of internet terrorism.
Cyber Security of Critical Infrastructure
Cybersecurity for critical infrastructure focuses on protecting essential systems and
assets that are vital for society and the economy. This includes sectors like energy,
transportation, and healthcare, which rely on systems like SCADA and ICS. The
goal is to prevent cyberattacks, natural disasters, and other threats from disrupting
these critical operations.
The entire infrastructural operations of the economy and society are dependent on
the safety of their vital systems networks and resources, and that is called
cybersecurity in critical infrastructure. Operating these critical infrastructures
against cyber-attacks is a must, and that is possible through putting in place high-
quality and strict policies.
