What Are Insider Threats?
Insider threats are security risks that originate from people within your organization. These could be employees, contractors, or vendors who have access to your systems—whether they mean harm or not.
Two Main Types of Insider Threats:
- Accidental – Unintentional mistakes, like clicking on phishing links or mishandling data.
- Malicious – Intentional acts, such as stealing sensitive files or sabotaging systems.
Why Insider Threats Matter for Atlanta SMBs
Small businesses often focus on external attacks—but internal threats are just as dangerous. Here’s why:
- Staff have direct access to sensitive information.
- Many SMBs lack detailed user access controls.
- There’s often no real-time monitoring for unusual activity.
Real-World Examples of Insider Threats
- An employee downloads a client list before leaving the company.
- A staff member accidentally uploads sensitive files to a public folder.
- A contractor installs unauthorized software that creates a backdoor into your system.
Top Ways to Minimize Insider Threat Risks
- Use Role-Based Access Control (RBAC)
Give employees access only to the tools and data they need—no more, no less. - Set Up Activity Monitoring
Track user activity with automated alerts for suspicious behavior. - Train Your Team Regularly
- Teach how to spot phishing attempts
- Explain the importance of data handling
- Reinforce policies on removable media (USBs, external drives)
- Revoke Access Immediately
Have an offboarding checklist. Disable email, software logins, and shared drive access right away when someone leaves. - Implement Two-Factor Authentication (2FA)
Even if credentials are stolen, 2FA adds an extra layer of protection.
Best Practices for Prevention
- Review permissions monthly
- Use managed IT services to monitor, audit, and patch vulnerabilities
- Encrypt sensitive files and limit downloads
- Monitor printing and file transfers in shared environments
- Document clear security policies and enforce them
