The CIA Triad, sometimes referred to as the “AIC Triad” stands for Confidentiality, integrity. Many workforces use the CIA Triad to help guide their policies for information security. Although In today’s society, these three elements are crucial in the cybersecurity field, many people believe that it is time for an upgrade.

 Confidentiality

 Confidentiality is often referred to as privacy, Confidentiality ensures that information is accessible only to authorized individuals or entities. To do this, access to information must be restricted to avoid the purposeful or unintentional sharing of data with unauthorized parties. An example of Confidentiality would be encryption, encryption is a type of data security that converts information to ciphertext. Only authorized individuals with the key may decrypt the code and access the original plaintext data. To prevent data breaches, you may classify and label restricted material, establish access control measures, encrypt data, and deploy multi-factor authentication (MFA) systems. It is also crucial to ensure that everyone in the business has the necessary training and information to spot and prevent potential hazards. 

Integrity   

Integrity entails ensuring that your data is trustworthy and free of manipulation; integrity is only maintained if the data is authentic, accurate, and dependable. Data must not be modified in transit, and precautions must be taken to prevent unauthorized parties from altering data. An example of integrity would be ATM and bank software protecting data integrity by guaranteeing that any transfers or withdrawals performed through the machine are accounted for in the user’s bank account. 

Availability

Availability guarantees that information and systems are available and usable when needed. It entails preventing disruptions or unlawful denial of service. Redundancy, fault tolerance, and disaster recovery strategies are utilized to maximize availability. For example, establishing redundant servers or employing load-balancing techniques can assist in ensuring that a website remains available even if one server fails. 

Authentication/Authorization 

Authentication is the process of confirming the identity of a user or organization attempting to access a system or resource. It validates the claimed identity and compares it to the credentials provided. Passwords, digital certificates, biometrics, and multifactor authentication are all types of authentications. When you input your username and password to log into an online banking website, for example, the system validates that the credentials you entered match those in its database. 

Authorization, on the other hand, follows authentication and decides what activities or resources a validated user is permitted to access. It entails granting or denying rights based on the privileges or roles of the authenticated user. Access control technologies such as access control lists (ACLs) or role-based access control (RBAC) are commonly used to implement authorization. For example, after logging into a system, your user account may be permitted to view but not alter or remove specific files or directories. 

Conclusion

In conclusion, all the elements listed above are key factors to security in modern day businesses. All companies should implement the CIA Triad to better secure their information and ours. Doing so will give any company a great defense mechanism when facing data breaches from unauthorized users.
