Protecting information is key for organizations especially when it comes to Controlled Unclassified Information (CUI). Many ask what level of security is needed to protect this information.

For CUI a moderate level of system and network config is required. Meaning organizations need to put in some controls but not the highest level of security used for classified information.

The moderate config keeps CUI from unauthorized access while still allowing authorized personnel to use the information when needed. It’s a balance of security and usability which is key for many government and military organizations that use CUI in their daily work.

What is Controlled Unclassified Information (CUI)

CUI is a type of government information that requires special handling. It’s important to know what CUI is and how to manage it.

What is CUI?

CUI stands for Controlled Unclassified Information. It’s government information the government creates or owns that needs protection but isn’t secret enough to be classified. The Department of Defense (DoD) and other agencies use CUI to protect sensitive data.

CUI can be personal info, technical data or export controlled information. It’s not top secret but not for everyone to see either. The government has rules on who can access CUI and how to protect it.

People working with CUI have to be careful. They can only share it for official purposes. If someone accidentally leaks CUI they can get in trouble.

CUI Categories and Handling

The government breaks CUI into different categories. Each category has its own set of rules. Some CUI requires more care while others are less strict.

Here are some CUI categories:

  • ISOO CUI Registry has all the official categories
  • DoD follows DODI 5200.48 for its CUI
  • CUI often has special markings to indicate how to handle it

When working with CUI, you need to:

  1. Check who can see the information
  2. Use secure methods to share CUI
  3. Label documents with CUI markings
  4. Store CUI in approved locked containers

By following these steps, you help keep sensitive information safe. It’s a team effort to protect CUI across government.

Safeguarding and Maintenance Protocols

Protecting sensitive information requires special handling and secure systems. Both technical controls and human vigilance are key to keeping CUI safe.

Safeguarding CUI

CUI must be stored on systems with moderate confidentiality controls. Meaning strong passwords, encryption and access limits. Networks should have firewalls and monitoring to detect unusual activity. Regular backups to prevent data loss.

Physical controls matter too. Keep CUI documents in locked cabinets when not in use. Shred papers before throwing them away. Be careful when discussing CUI in public places where others may overhear.

IT teams should patch systems quickly to fix vulnerabilities. They should also run scans to detect viruses or unauthorized changes. Having an incident response plan helps teams respond quickly if something goes wrong.

Contractor and Personnel Responsibilities

Anyone who handles CUI has a responsibility to protect it. This includes government employees, military personnel and contractors. They need CUI training and awareness.

Workers should only access CUI they really need for their job. They should report any suspected leaks immediately. Sharing CUI requires checking if the other person is allowed to see it.

Contractors have additional requirements under the National Industrial Security Program. They need secure facilities and IT systems to work with CUI. Regular security checks to ensure they are following the rules.

Leaving a job doesn’t end CUI responsibilities. People must return or destroy any CUI they have. They can’t discuss CUI they learned on the job. These ongoing responsibilities help keep sensitive information safe long term.
