You know what they say, knowledge is power. And when it comes to cybersecurity, knowledge can mean the difference between safety or being exposed to a digital threat. That’s why today, I’d like to share with you about the 4 types of data classification – something every individual and organization should be aware of to protect themselves from cyber attacks.

You might think, “Oh, but I’m not a big corporation, why would cyber criminals target me?” but the truth is that every single one of us has valuable information that can be exploited. Bank account details, login credentials, personal contacts – all of it can be used to commit fraud, launch phishing attacks, and more. But by understanding data classification, we can better protect ourselves and prevent cybercrime.

So hang on tight, because I’m about to give you a rundown on the 4 types of data classification that you need to know. Trust me, it’s worth it.

What are the 4 types of data classification?

Introduction

Data classification is the process of categorizing data based on its level of sensitivity and the potential risk associated with its unauthorized access or disclosure. Data is classified into different levels to ensure appropriate handling measures are implemented, and access to data is restricted to authorized personnel only. The University utilizes four classifications of data: Controlled Unclassified Information, Restricted, Controlled, and Public. Each classification has its own set of requirements regarding data handling, storage, and access, depending on the level of risk associated with the data.

Controlled Unclassified Information

Controlled Unclassified Information (CUI) is data that requires safeguarding or dissemination controls under laws, regulations, or government-wide policies but is not classified under Executive Order (EO) 13526 or the Atomic Energy Act. CUI may contain sensitive and confidential information that, if improperly handled or disclosed, could cause harm to individuals, assets, or national security. Examples of CUI include Department of Defense (DoD) information, Export-Controlled data, and other sensitive information subject to legal or regulatory controls.

Some of the requirements for handling CUI are:

• Access to CUI should be provided only to authorized individuals with an established need-to-know.
• CUI should be stored in secure locations and protected by physical and technical safeguards.
• CUI should be transmitted only through secure channels and with proper encryption and security controls in place.

Restricted Data

Restricted Data (RD) is a classification of data used to identify information regarding the design, manufacture, or utilization of nuclear weapons. The RD classification is used to ensure that information vital to national security is protected from unauthorized disclosure. The National Nuclear Security Administration (NNSA) oversees RD and has implemented strict controls on its handling and storage.

Some of the requirements for handling RD are:

• Access to RD should be provided only to authorized individuals with an established need-to-know and appropriate clearances.
• RD should be stored in secure locations and protected by physical and technical safeguards.
• RD should be transmitted only through authorized channels and with proper encryption and security controls in place.

Controlled Data

Controlled Data (CD) is data that has been determined to require protection against unauthorized disclosure, but does not meet the criteria for CUI or RD classification. CD may contain sensitive or confidential information, such as student records, financial data, or proprietary information. CD classification is typically determined by the data owner or custodian.

Some of the requirements for handling CD are:

• Access to CD should be provided only to authorized individuals with an established need-to-know.
• CD should be stored in secure locations and protected by physical and technical safeguards.
• CD should be transmitted only through secure channels and with proper encryption and security controls in place.

Public Data

Public Data is data that has been determined to have no sensitive information and can be freely disclosed without restriction. Public data includes information such as press releases, public directories, and general information about the University. Public data may be accessed and disseminated without any special requirements or restrictions.

Importance of Data Classification

Data classification is essential for protecting sensitive data and ensuring that it is handled appropriately. By categorizing data into different classifications, organizations can develop policies and procedures for handling data based on the level of risk associated with it. This ensures that sensitive data is only accessible by authorized individuals with a need-to-know, and that data is stored and transmitted in a secure manner.

Data classification also helps organizations comply with legal and regulatory requirements for safeguarding certain types of data. By identifying and classifying sensitive data, organizations can ensure that they are meeting all necessary legal and regulatory obligations regarding data protection and security.

Conclusion

In conclusion, data classification is a critical process for protecting sensitive data and ensuring that it is handled, stored, and transmitted appropriately. By utilizing classifications such as CUI, RD, CD, and Public, organizations can ensure that they are meeting all necessary regulatory requirements and protecting sensitive information from unauthorized access or disclosure. Data classification should be a part of every organization’s data security strategy, with policies and procedures in place for each classification to ensure that data is being handled in a secure and appropriate manner.
