To mitigate the risk of sensitive data being exfiltrated from the environment, the IT manager should implement a Data Loss Prevention (DLP) solution. DLP monitors and controls the movement of sensitive data, ensuring that unauthorized transfers are blocked and potential data breaches are prevented.
* XDR (Extended Detection and Response) is useful for threat detection across multiple environments but doesn't specifically address data exfiltration.
* SPF (Sender Policy Framework) helps prevent email spoofing, not data exfiltration.
* DMARC (Domain-based Message Authentication, Reporting & Conformance) also addresses email security and spoofing, not data exfiltration.
