The 5 Pillars of Information Security and How to Manage Them | Infinit-O Global (2024)

In the progressively competitive business world, information is a valuable resource that needs utmost protection. Information security is integral in managing your business and ensuring that vital information is not compromised in any way.

Securing information is paramount for the survival of your enterprise. Hence, it must be proactively secured against malicious attacks especially when business information is transmitted over networks.

A secure information system is built on the foundation of five essential building blocks. Setting these pillars properly into place is central to developing any kind of information security mechanism in your business. Read on.

Information Assurance (IA) is the practice of protecting against and managing risks related to the use, processing, storage, and transmission of data and information systems. The U.S. Department of Defense has promulgated the Five Pillars of Information Assurance model that includes the protection of confidentiality, integrity, availability, authenticity, and non-repudiation of user data.

Here are the five pillars of the IA framework that you need to manage in your office cyberspace:

This is the assurance that information is not disclosed to unauthorized individuals, groups, processes, or devices. Highly confidential data must be encrypted so third parties cannot easily decrypt it. Only those who are authorized to view the information are allowed access.

The accuracy and completeness of vital information must be safeguarded. Data should not be altered or destroyed during transmission and storage. This involves making sure that an information system is not tampered by any unauthorized entities. Policies should be in place so that users know how to properly utilize their system.

This means that authorized users have timely and easy access to information services. IT resources and infrastructure should remain robust and fully-functional at all times even during adverse conditions, such as database conundrum or fall-overs. It involves protecting against malicious codes, hackers, and other threats that could block access to the information system.

This security measure is designed to establish the validity of a transmission, message, or originator, or a means of verifying an individual’s authorization to receive specific information. Authentication prevents impersonation and requires users to confirm their identities before being allowed access to systems and resources. This includes user names, passwords, emails, biometrics, and others.

This attribute assures the sender of data is provided with proof of delivery and the recipient is provided with proof of the sender’s identity, so neither party can deny sending, receiving, or accessing the data. Security principles should be used to prove identities and to validate the communication process.
