CIA, IN THE CONTEXT OF COMPUTER SECURITY,

STANDS

FOR CONFIDENTIALITY, INTEGRITY,
AND

AVAILABILITY. IT IS A FOUNDATIONAL CONCEPT THAT

HELPS ORGANIZATIONS IDENTIFY AND IMPLEMENT

APPROPRIATE

TO

PROTECT

AGAINST UNAUTHORIZED ACCESS, DATA BREACHES,

UNAUTHORIZED

MODIFICATIONS,
AND

SERVICE

DISRUPTIONS.

ITS MAIN ELEMENTS ARE:

DEFINITION OF CIA

CONFIDENTIALITY

❖ Confidentiality focuses on keeping sensitive or

classified information private and accessible only
to authorized individuals or entities.

❖ Ensures that information remains confidential

and is not disclosed to unauthorized parties.

❖Encryption, access controls, user authentication,

and

secure

communication

protocols

are

commonly employed to maintain confidentiality.

INTEGRITY

❖Integrity ensures the trustworthiness, accuracy, and

guarantees that data remains unaltered and retains its
intended state and meaning.

❖Data

integrity

measures

focus

on

preventing

unauthorized modifications, deletions, or corruption
of data.

❖Techniques such as checksums, hashing algorithms,

digital signatures, and access controls are used to
ensure data integrity.

AVAILABILITY

❖ Availability ensures that computer systems, resources,

and services are accessible when needed even if there is
a security breach.

❖ Availability

measures

include

redundancy,

fault

tolerance, backup and recovery mechanisms, and disaster
recovery plans.

❖ These measures ensure that systems can recover quickly

from failures or incidents, allowing users to access
resources and perform their tasks without interruptions

TYPES OF COMPUTER SECURITY

Here are a few types of computer security tactics
that are used widely for the protection of software,
hardware, electronic data, and network in computer
systems.
• Application Security
• Information Security
• Network Security
• Endpoint Security
• Internet Security

APPLICATION SECURITY

Application security is the introduction of security
features in applications during their development
process.

Some examples of application security tools are
antivirus software, firewalls, web application
firewalls, encryption, etc.

INFORMATION SECURITY

Information security is a set of practices that aim to
protect the confidentiality, integrity, and availability
(known as the CIA triad) of data from unauthorized
access and misuse.

NETWORK SECURITY

Network security is any activity that aims to
protect the integrity and usability of a network and
data. It consists of both hardware and software
technologies that are specifically designed to
prevent unauthorized intrusion into computer
systems and networks

ENDPOINT SECURITY

Endpoint security, like endpoint detection and
response, is the process of protecting devices like
workstations, servers, and other devices (that can
accept a security client) from malicious threats
and cyberattacks.

INTERNET SECURITY

Internet security is one of the most important types of
computer security that come with a set of rules and
protocols that focus on specific threats and activities
that happen online. It provides protection against
hacking, DoS attacks, computer viruses, and malware.

BENEFITS

Computer security provides numerous benefits that
are essential for individuals, organizations, and
society as a whole. Here are some key benefits of
computer security:
➢Data protection
➢Preventing unauthorized access
➢Preventing cyber attacks
➢Promoting a safer digital environment
