Question
An IT manager is increasing the security capabilities of an organization after a data classification initiative determined that sensitive data could be exfiltrated from the environment. Which of the following solutions would mitigate the risk?
A. XDR
B. SPF
C. DLP
D. DMARC
Answer
C. DLP (Data Loss Prevention)
Explanation
Data Loss Prevention (DLP) solutions are designed to identify, monitor, and protect sensitive data to prevent unauthorized access, use, or exfiltration. After a data classification initiative determines that sensitive information could be exfiltrated from the environment, implementing a DLP solution is the most effective way to mitigate this risk.
DLP solutions work by:
- Identifying and classifying sensitive data based on predefined policies and rules.
- Monitoring data in use, data in motion, and data at rest to detect potential policy violations or unauthorized access attempts.
- Enforcing security policies, such as blocking, quarantining, or encrypting sensitive data to prevent unauthorized exfiltration.
The other options are not directly related to preventing sensitive data exfiltration:
A. XDR (Extended Detection and Response) is a security approach that provides comprehensive threat detection and response capabilities across multiple security layers, but it does not specifically focus on preventing data exfiltration.
B. SPF (Sender Policy Framework) is an email authentication protocol that helps prevent email spoofing by verifying the legitimacy of the sender’s domain. While it enhances email security, it does not directly address data exfiltration risks.
D. DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that builds upon SPF and DKIM to provide additional protection against email spoofing and phishing. Like SPF, it does not directly mitigate the risk of sensitive data exfiltration.
Therefore, DLP is the most appropriate solution to mitigate the risk of sensitive data exfiltration after a data classification initiative.
