According to CNSSI No. 4009, Spillage is a:
"Security incident that results in the transfer of classified or CUI information onto an information system not accredited (i.e., authorized) for the appropriate security level."
Examples include, but are not limited to:
"When there is evidence of a possible spillage of classified national security information, hereinafter "classified information," an immediate notification shall be made to the information owner, the information assurance manager, the activity security manager, and the responsible Incident Response Center (IRC) Responsible personnel shall conduct an immediate preliminary inquiry to determine whether the classified information was subjected to loss, possible compromise, or unauthorized disclosure. "
Report the spillage to your security POC.
B. Report the spillage to your security POC.
The classified data, sent over an unclassified network, must be securely encrypted.
Spillage should be reported regardless of whether you believe the system is compromised, as it ensures that potential risks are assessed and managed appropriately. Early reporting can help minimize damage, facilitate a thorough investigation, and implement necessary security measures. Additionally, even if the compromise is not immediately evident, spillage can still pose significant security threats that need to be addressed. Prompt reporting fosters a culture of transparency and accountability in information security.
Classified information is entered onto an unclassified network
Spillage is when information classified at a higher level is introduced to a computer classified at a lower level. In practice it includes any instance where such information MAY have been introduced. As an example: a laptop computer that is normally connected to a lower classification level network is connected to a higher level network in an attempt to check email. It is unknown if any higher classification data was transferred during the connection. The incident is treated as potential spillage and the hard drive of the computer is now considered classified.

Classified information is entered onto an unclassified network.
To avoid spillage of sensitive information Agnes should have protection controls in place. For example, have a file-based encryption and perform integrity checks.
Spillage on a government computer refers to the unauthorized disclosure or transfer of classified or sensitive information to a less secure system or environment, often involving the accidental exposure of such data. This can occur through various means, such as improper handling of documents, using unapproved devices, or failing to follow security protocols. Spillage poses significant risks to national security, privacy, and data integrity, prompting stringent regulations and reporting requirements within government agencies. Addressing spillage incidents typically involves immediate containment measures and a thorough investigation to prevent future occurrences.

If the spillage of classified information occurs, you must immediately report the incident to your supervisor or the designated security officer. It’s crucial to contain the situation by limiting access to the information and preserving any evidence related to the breach. Follow the established protocols for incident response, which may include notifying relevant authorities and conducting an investigation. Finally, assess and implement measures to prevent future occurrences.
