Definition of Information Security
The protection of personal data from unauthorized access and changes during storage or transmission is the main goal of information security practices. These practices are put in place to ensure the safety of sensitive information.
The purpose of information security is to safeguard private, sensitive, and personal data from unauthorized individuals through the use of measures for print and electronic materials. It serves to prevent the misuse, disclosure, destruction, modification, and disruption of data.
Comparison between Information Security and Cybersecurity
The terms information security and cybersecurity are often interchangeable, but they refer to distinct concepts. Cybersecurity is a method employed to safeguard against online attacks, whereas information security is a specialized field within cybersecurity. Specifically, information security is concerned with protecting network and application code.
Principle of Information Security
The following will delve into the fundamental elements of information security.
Confidentiality is an essential aspect of information security, which ensures that only authorized individuals have access to data.
To maintain confidentiality, it is necessary to implement various security techniques such as using strong passwords, encryption, authentication, and protection against penetration attacks.
Integrity, on the other hand, involves safeguarding data from any unauthorized modifications, whether intentional or accidental. The same techniques used for confidentiality can also help protect data integrity, as cybercriminals cannot modify data if they cannot access it. In order to enhance integrity, several tools are available that provide in-depth protection.
Availability is also a crucial element of information security, and it is important to ensure that only authorized individuals can access data. This means matching network and computing resources to enable data access and implementing effective disaster recovery policies.

Policy on Information Security
An enterprise creates an information security policy according to its individual requirements and peculiarities. This document outlines the data that needs to be safeguarded and the methods to be used. Such policies assist organizations in making decisions regarding the acquisition of cybersecurity tools and also dictate employee conduct and duties.
A comprehensive information security policy for an organization should encompass the following elements:
The information security program and goals should be clearly outlined. The document should also define key terms to promote mutual understanding. A password policy should be included, and access to data should be determined. Additionally, the roles and responsibilities of employees in protecting data must be included.
