To detect an employee who is emailing a customer list to a personal account before leaving the company, a Data Loss Prevention (DLP) system would be used. DLP systems are designed to detect and prevent unauthorized transmission of sensitive data.
DLP (Data Loss Prevention): Monitors and controls data transfers to ensure sensitive information is not sent to unauthorized recipients.
FIM (File Integrity Monitoring): Monitors changes to files to detect unauthorized modifications.
IDS (Intrusion Detection System): Monitors network traffic for suspicious activity but does not specifically prevent data leakage.
EDR (Endpoint Detection and Response): Monitors and responds to threats on endpoints but is not specifically focused on data leakage.
