Data Loss Prevention

Use a data loss prevention (DLP) strategy to categorize sensitive data, identify data formats indicative of personal identifiable information (PII), and restrict exfiltration of sensitive data.(Citation: PurpleSec Data Loss Prevention)

Techniques Addressed by Mitigation
Domain ID Name Use
Enterprise T1020 T1020.001 Automated Exfiltration: Traffic Duplication

Implement Data Loss Prevention (DLP) solutions to monitor, detect, and control the flow of sensitive information. DLP tools can be configured to block unauthorized attempts to exfiltrate data, such as preventing emails from being forwarded to external recipients or monitoring for suspicious data transfers. By creating email flow rules and applying policies to detect anomalies, DLP solutions help mitigate the risk of data exfiltration over alternative protocols.
Enterprise T1005 Data from Local System

Data loss prevention can restrict access to sensitive data and detect sensitive data that is unencrypted.

Enterprise T1025 Data from Removable Media

Data loss prevention can restrict access to sensitive data and detect sensitive data that is unencrypted.

Enterprise T1048 Exfiltration Over Alternative Protocol

Data loss prevention can detect and block sensitive data being uploaded via web browsers.

T1048.002 Exfiltration Over Asymmetric Encrypted Non-C2 Protocol

Data loss prevention can detect and block sensitive data being uploaded via web browsers.

T1048.003 Exfiltration Over Unencrypted Non-C2 Protocol

Data loss prevention can detect and block sensitive data being sent over unencrypted protocols.

Enterprise T1041 Exfiltration Over C2 Channel

Data loss prevention can detect and block sensitive data being sent over unencrypted protocols.

Enterprise T1052 Exfiltration Over Physical Medium

Data loss prevention can detect and block sensitive data being copied to physical mediums.

T1052.001 Exfiltration over USB

Data loss prevention can detect and block sensitive data being copied to USB devices.

Enterprise T1567 Exfiltration Over Web Service

Data loss prevention can be detect and block sensitive data being uploaded to web services via web browsers.

T1567.004 Exfiltration Over Webhook

Data loss prevention can be detect and block sensitive data being uploaded to web services via web browsers.

Enterprise T1537 Transfer Data to Cloud Account

Data loss prevention can prevent and block sensitive data from being shared with individuals outside an organization.(Citation: Microsoft Purview Data Loss Prevention) (Citation: Google Workspace Data Loss Prevention)
