DLP: Data Loss Prevention in Cybersecurity
DLP stands for Data Loss Prevention. DLP systems detect and prevent unauthorized transmission of sensitive data outside an organization's boundaries. They monitor data in motion, at rest, and in use across endpoints, networks, and cloud services.
How DLP Is Used in Cybersecurity
GRC analysts define DLP policies based on regulatory requirements like PCI DSS and HIPAA. Security engineers deploy DLP agents on endpoints and configure network-level inspection to catch sensitive data exfiltration. SOC analysts investigate DLP alerts to determine if a data transfer was intentional or a sign of insider threat activity.
