"Which of the Following is True of Protecting Classified Data"


Protecting classified data is essential to maintaining national security and the integrity of sensitive information. Understanding the best practices and strategies to protect such data is crucial for anyone handling classified information. This article will cover various aspects of data protection, including the best ways to safeguard your Common Access Card (CAC), practices for protecting controlled unclassified information, identifying different types of malicious code, and preventing data spillage.

Best Ways to Protect Your CAC

The Common Access Card (CAC) is a critical access control component in many government and military environments. Protecting your CAC ensures that unauthorized individuals do not gain access to sensitive information. Here are some best practices:

  1. Physical Security: Always keep your CAC on your person and never leave it unattended. If not in use, store it in a secure location.
  2. Digital Security: Do not share your PIN or other authentication information with anyone. Update your PIN regularly and report any suspicious activities immediately.
  3. Awareness: Be vigilant about your surroundings and avoid using your CAC in insecure locations.

Best Practices for Protecting Controlled Unclassified Information (CUI)

Controlled Unclassified Information (CUI) requires careful handling to prevent unauthorized access and ensure data integrity. Best practices include:

  1. Access Control: Limit access to CUI to authorized personnel only. Use role-based access control to ensure that individuals only have access to the information necessary for their role.
  2. Data Encryption: Encrypt CUI at rest and in transit to protect it from unauthorized access and tampering.
  3. Regular Audits: Conduct audits and assessments to ensure compliance with CUI handling protocols and identify potential vulnerabilities.

Identifying Malicious Code

Understanding different types of malicious code is essential in protecting classified data. Some types of malicious code include:

  1. Viruses attach themselves to legitimate programs and can spread to other systems.
  2. Worms: Unlike viruses, worms can replicate and spread independently.
  3. Trojans: These appear as legitimate software but perform malicious activities once executed.
  4. Ransomware: This malicious software encrypts data and demands a ransom for its release.

However, it’s important to note that “which is” not a type of malicious code” is crucial for understanding and mitigating threats accurately.

Preventing Data Spillage

Data spillage, or the unauthorized transfer of classified information to an unclassified system or environment, can have severe consequences. To prevent spillage, consider the following:

  1. User Training: Regular training and awareness programs can help users understand the importance of data security and how to prevent spillage.
  2. Technical Controls: Implementing technical controls such as data loss prevention (DLP) tools and automated classification marking can help prevent accidental spillage.
  3. Incident Response: A robust incident response plan can help quickly address and mitigate the impact of any spillage.

Cyber Awareness and Spillage Prevention

Cyber awareness plays a crucial role in preventing data spillage. Organizations can reduce the risk of accidental data leaks by fostering a culture of security and awareness. Regular training sessions, phishing simulations, and awareness campaigns can help keep data security at the forefront of all employees’ minds.


Protecting classified data involves a comprehensive approach that includes physical and digital security measures, awareness, and training. By following best practices for protecting your CAC, controlling unclassified information, understanding malicious code, and preventing data spillage, you can help ensure the security and integrity of sensitive information.

People Also Ask

Q: What is the best way to protect your CAC?
A: The best way to protect your CAC is to keep it on your person at all times, never share your PIN, regularly update your PIN, and be vigilant about your surroundings.

Q: What is the best practice for protecting controlled, unclassified information?
A: Best practices for protecting controlled unclassified information include limiting access to authorized personnel, encrypting data at rest and in transit, and conducting regular audits.

Q: Which is not a type of malicious code?
A: While viruses, worms, trojans, and ransomware are types of malicious code, software bugs or glitches are not considered malicious code.

Q: Which of the following may help to prevent spillage?
A: Regular user training, implementing technical controls like data loss prevention tools, and having a robust incident response plan can help prevent data spillage.

Q: What is spillage in cyber awareness?
A: Spillage in cyber awareness refers to the unauthorized transfer of classified information to an unclassified system or environment, which can lead to data leaks and security breaches.
