Protect against insider threats.

Insider threats remain one of the most overlooked risks in cyber resilience. Whether intentional or accidental, actions from within the organization can cause significant damage. The recommendations below provide practical steps to help SMBs and senior leaders reduce the risk and impact of insider threats.

Top Recommendations to Protect Against Insider Threats

1. Monitor, Without Micromanaging
   Use User Behavior Analytics (UBA) or activity logs to spot anomalies like unusual login times, large file downloads, or access to restricted data. Focus on patterns, not paranoia.

2. Restrict Access by Role (Least Privilege)
   Employees should only access the data and systems they need to do their jobs.  No more “everyone’s an admin” setups,reduce that attack surface.

3. Regular Access & Activity Audits
   Run quarterly audits to review user permissions and detect unauthorized access.  Remove stale accounts and check for privilege creep.

4. Ongoing Cyber Awareness Training
   Train staff to recognize social engineering, spear phishing, and signs of malicious insiders.  Real-world stories work better than dry slides.

5. Deploy Data Loss Prevention (DLP) Tools
   DLP tools monitor for risky actions like sending sensitive files to personal email or uploading data to cloud storage.  Set alerts, not just blocks.

6. Enable Anonymous Reporting Channels
   Employees are more likely to report suspicious behaviour if they can do it confidentially.  Offer email hotlines, forms, or secure messaging options.

7. Have an Insider Threat Response Plan
   Just like any incident response plan, this should outline how you’ll investigate, contain, and respond to insider incidents, including legal and HR steps.

8. Build a Culture of Trust with Accountability
   Insider threats thrive in toxic environments.  Promote psychological safety, but make it clear that accountability and transparency are non-negotiable.
