We recently had a data leak caused by a disgruntled employee who had legitimate access to our database. Traditional firewalls and antivirus obviously didn't stop this. What User and Entity Behavior Analytics (UEBA) tools or internal policies have you found effective in detecting malicious internal activity?

Protecting against insiders requires a shift to "Identity-Centric" security. You need a DLP (Data Loss Prevention) solution that monitors data movement across endpoints. More importantly, UEBA (User and Entity Behavior Analytics) tools use machine learning to establish a "normal" baseline for every user. If an employee who usually downloads 10 files a day suddenly starts exporting thousands of rows of customer data at 2 AM on a Sunday, the system can automatically lock the account and alert the SOC. This proactive monitoring is the only way to catch someone who has the "keys to the castle."
How do you balance the need for intrusive monitoring with employee privacy and morale in a modern workplace?
Implementing "Just-In-Time" (JIT) access helped us. Users only get elevated permissions for the specific hour they need to do a task, then it auto-revokes.
That's a great approach, Karen. JIT access significantly reduces the "attack surface" an insider has to work with, making a massive data dump much harder to pull off.
Brian, transparency is key. To answer your question: we include the monitoring policy in the employee handbook and explain that it's for the company's protection. We don't monitor private chats or personal emails, but we make it very clear that any movement of "Proprietary Data" is logged and audited.
