Title: Isolate information spills
Ownership: Customer
Description: Microsoft recommends that your organization isolate any contaminated information system or system component involved in an information spill. Your organization should consider creating and maintaining an overall security incident response plan. Incidents of data spillage may occur at any time. Therefore, you should be prepared to deal with these incidents immediately. It is recommended that you identify and document the steps that the organization follows in spillage scenarios to access, identify, and delete data. Automate manual repetitive tasks to speed up response time and reduce the burden on analysts. Manual tasks take longer to execute, slowing each incident and reducing how many incidents an analyst can handle. Manual tasks also increase analyst fatigue, which increases the risk of human error that causes delays, and degrades the ability of analysts to focus effectively on complex tasks. Use workflow automation features in Azure Security Center and Azure Sentinel to automatically trigger actions or run a playbook to respond to incoming security alerts. The playbook takes actions, such as sending notifications, disabling accounts, and isolating problematic networks.

Control Domain Control Name MetadataId Category Title Owner Requirements Description Info Policy#
FedRAMP_High_R4 IR-9 FedRAMP_High_R4_IR-9 FedRAMP High IR-9 Incident Response Information Spillage Response Shared n/a The organization responds to information spills by: a. Identifying the specific information involved in the information system contamination; b. Alerting [Assignment: organization-defined personnel or roles] of the information spill using a method of communication not associated with the spill; c. Isolating the contaminated information system or system component; d. Eradicating the information from the contaminated information system or component; e. Identifying other information systems or system components that may have been subsequently contaminated; and f. Performing other [Assignment: organization-defined actions]. Supplemental Guidance: Information spillage refers to instances where either classified or sensitive information is inadvertently placed on information systems that are not authorized to process such information. Such information spills often occur when information that is initially thought to be of lower sensitivity is transmitted to an information system and then is subsequently determined to be of higher sensitivity. At that point, corrective action is required. The nature of the organizational response is generally based upon the degree of sensitivity of the spilled information (e.g., security category or classification level), the security capabilities of the information system, the specific nature of contaminated storage media, and the access authorizations (e.g., security clearances) of individuals with authorized access to the contaminated system. The methods used to communicate information about the spill after the fact do not involve methods directly associated with the actual spill to minimize the risk of further spreading the contamination before such contamination is isolated and eradicated.
