SC-44 — Detonation Chambers
Employ a detonation chamber capability within {{ insert: param, sc-44_odp }}.
Supplemental Guidance
Detonation chambers, also known as dynamic execution environments, allow organizations to open email attachments, execute untrusted or suspicious applications, and execute Universal Resource Locator requests in the safety of an isolated environment or a virtualized sandbox. Protected and isolated execution environments provide a means of determining whether the associated attachments or applications contain malicious code. While related to the concept of deception nets, the employment of detonation chambers is not intended to maintain a long-term environment in which adversaries can operate and their actions can be observed. Rather, detonation chambers are intended to quickly identify malicious code and either reduce the likelihood that the code is propagated to user environments of operation or prevent such propagation completely.
Practitioner Notes
Detonation chambers are isolated sandbox environments where suspicious files and code can be executed safely to observe their behavior before allowing them into your production environment.
Example 1: Deploy Microsoft Defender for Office 365 Safe Attachments, which opens email attachments in a cloud-based sandbox (detonation chamber) to detect malicious behavior. Attachments that trigger malware indicators are blocked from delivery to the user's mailbox.
Example 2: Set up a malware analysis sandbox (like Cuckoo Sandbox or Joe Sandbox) on an isolated network segment. Security analysts can submit suspicious files for automated behavioral analysis — the sandbox reports file system changes, network connections, and registry modifications without risking your production environment.
