security overview
Common Vulnerabilities:
- Unauthorized access if default credentials are not changed or if strong authentication is not enforced
- Possible exploitation by attackers to gain remote desktop or file access if ports are exposed to the internet
- Vulnerability to man-in-the-middle attacks if communications are unencrypted
- Risk of lateral movement within a network via compromised hosts
Common Mitigations:
- Enforce strong authentication and change default passwords
- Limit exposure by restricting port 5405 to internal or trusted networks via firewall rules
- Enable encryption features if available in NetSupport Manager
- Utilize network segmentation to isolate management networks
- Regularly update and patch the software to address security vulnerabilities
- Monitor remote access logs and network activity for anomalies
