IA ensures data safety, regardless of the format in which it exists. Whether it’s digital, printed, or verbal information, IA aims to safeguard it under the five key principles: confidentiality, integrity, availability, authenticity, and non-repudiation.


The confidentiality principle focuses on ensuring that data access is limited to authorized personnel only. It prevents sensitive information from falling into the wrong hands. This feature is similar to a cybersecurity policy, which may involve password-protected files or encrypted communications.


The integrity principle of IA ensures that information remains accurate and original throughout its processing, transmission, and storage phases. This feature prevents unauthorized modification or deletion of data. Cybersecurity also upholds this principle using methods such as security patches to prevent hackers from exploiting weaknesses in the system.


Availability in IA is the assurance that resources (information and systems) are available when needed. This principle ensures that a system can recover and continue operation even during a security event. In cybersecurity, this could mean installing redundancy measures to minimize downtime during an attack or system failure.


Authenticity in IA involves verifying the identity of users, systems, and information. It’s the guarantee that people are who they claim to be, systems are valid, and data is from a trusted source. Usernames, two-factor authentication, and digital signatures are some cybersecurity measures that uphold authenticity.


Non-repudiation is unique to information assurance. It guarantees that a party in a transaction cannot deny their involvement or the authenticity of their digital signature. Cybersecurity tools like digital signatures and trusted timestamps support this principle.
