The CIA triad, which is widely accepted as a framework for evaluating and prioritizing security of a system or network, is widely accepted. It stands for Confidentiality. Integrity. And Availability. These are the three main pillars in cybersecurity.
Confidentiality is the protection of information against unauthorized access and disclosure. This means that only authorized personnel can have access to sensitive data and that data cannot be viewed or accessed if the owner is not authorized. Because it prevents unauthorized access to sensitive data, which could be used for malicious purposes like identity theft or fraud, confidentiality is essential.
Integrity is about the completeness and accuracy of data. It is the ability to ensure that data isn’t altered or destroyed in any way and that it remains in its original form. Integrity is essential because it prevents mistakes and errors that could have serious consequences such as financial loss or damage to a company’s reputation.
Availability is the ability to access a system or network and allow authorized users to use it. This means that the system or network can be accessed and used by authorized users. It is vital that the system or network is available in order to ensure that it can be used according to its intended purpose and is not interrupted by security incidents or attacks.
The CIA triad can be used to prioritise and prioritize security measures as well as evaluate the effectiveness of existing security precautions. If a company is worried about financial confidentiality, it might focus on encryption and strong passwords to protect that data. If the company is more concerned with the availability of its system, it might focus on measures to prevent downtime such as redundant servers or backup systems.
The CIA triad provides a framework for understanding and managing security in a network or system. Companies can improve the security of their data and systems by focusing on confidentiality integrity and availability. This will ensure that they can operate efficiently and smoothly.
