Technical Details
what runs on :13786Port 13786 services Symantec's Network Operations Manager Database (NOMDB), a component crucial in orchestrating enterprise data protection and management environments. Originally a VERITAS solution before acquisition, it underpins operations such as monitoring backup jobs, managing storage devices, and collecting logs from target endpoints.
NOMDB typically listens over both TCP and UDP, handling requests like status queries, control instructions, and data replication coordination. Its client-server communication model helps in centralizing administrative functions, enabling large-scale management of distributed backup infrastructures.
The port's protocol exchanges include serialized control data and status updates, often embedded within a proprietary communication protocol developed by Symantec. Integrations with other Symantec services may occur over this port as well, facilitating automated workflows and alerting.

security overview
Common Vulnerabilities:
- Unauthorized access if strong authentication is not enforced.
- Man-in-the-middle attacks exploiting unencrypted traffic.
- Potential for denial of service if unfiltered from public networks.
- Exploitation through vulnerabilities in out-of-date Symantec/VERITAS management servers.
Common Mitigations:
- Place management servers within a secured network segment, never exposed to the internet.
- Implement strict firewall rules, only allowing trusted IPs.
- Use strong authentication and access controls on management interfaces.
- Apply latest security patches provided by Symantec to reduce exploitable vulnerabilities.
- Where possible, tunnel communication over encrypted channels such as VPNs or utilize TLS/SSL if supported.
