4 Major Types of Information Security

There are 4 major types of information security that need be listed here for easy identification; especially for us who are far from being informed about the IT world, the recognition of the 4 four types of this kind of security certainly provides us with necessary details on how to secure our information.

Information security, also identified as InfoSec, is the practice of protecting information by mitigating information risks. It is part of information risk management.

This huge course of security in the field of information technology involves preventing or reducing the probability of unauthorized/inappropriate access to data, or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information.

Information security’s primary focus is the balanced protection of the data confidentiality, data integrity, and data availability of data, called the CIA triad, while maintaining a focus on efficient policy implementation, all without hampering organization productivity.

Is Information Security a Discipline?

Being a multidisciplinary area of study and professional activity which is concerned with the development and implementation of security mechanisms of all available types, information security keeps information in all its locations, regardless of perimeter).

It also helps to create, process, store, and transmit information as well as destroy possible threats.

The field of information security has grown and evolved significantly in recent years. It offers many areas for specialization.

These fields include securing networks and allied infrastructure, securing applications and databases, security testing, information systems auditing, business continuity planning, electronic record discovery, and digital forensics. Information security professionals are very stable in their employment.

4 Major Kinds of InfoSec

Here are the 4 major types of information security that you need to know:

Infrastructure Security

Infrastructure security refers to the measures taken to protect and secure an organization’s critical assets and resources, such as networks, systems, and data. It plays a critical role in protecting against cyber threats, maintaining data confidentiality and integrity, and ensuring business continuity.

Regular security assessments and vulnerability scans should also be conducted to identify potential risks and implement remediation measures. Additionally, implementing data backup and disaster recovery plans can help to minimize the impact of a security breach or system failure.

Overall, Infrastructure Security requires a combination of technology and various measures to effectively protect against cyber threats and ensure the stability of critical systems and data.

Cloud Security

Cloud Security is a collection of policies and procedures that protects data and applications stored in a cloud-based computing environment from unauthorized access, loss, and damage. Cloud Security involves implementing various measures such as firewalls, access controls, encryption, secure data transfer protocols, and regular security assessments to ensure the protection of sensitive data and applications.


Cryptography is one of the types of Information Security, which is used to secure data and communications by converting it into a secure, unreadable format to protect the data from unauthorized access or manipulation. Cryptography uses mathematical algorithms, keys, and protocols to ensure the confidentiality, integrity, and authenticity of data.

Application Security

It describes the measures taken to secure the data from unwanted access, misuse, and disruption to applications and systems. It is essential for securing confidential information, and user data. Strong authentication and authorization procedures should be used by organizations, along with regular security audits and the use of encryption for sensitive data.

Additionally, developers should follow secure coding practices, such as input validation and error handling, to reduce the risk of vulnerabilities in the application. Regular software updates and patches are also crucial to fix known security issues.

Application Security is essential for protecting against cyber-attacks, maintaining the confidentiality and integrity of data, and ensuring compliance with regulations.
