Security Groups for Teradata Database

When configuring a security group for the Teradata Database, set up the port ranges listed below for each Teradata Database instance so the Teradata Database can be locked down to the local host. Port 1025 is blocked in the local instance until the DBC password is changed.

If you use NTP, ensure the VPC ACL setting is not blocking UDP port 123 for both inbound and outbound traffic.

When launching a Teradata Database MPP instance using CloudFormation, access is restricted to IP addresses in the CIDR block specified in the Remote Access From parameter. If you have other Teradata software instances residing outside that IP range, you can edit the security group after launching to add the necessary IP addresses. Teradata software instances that may need access to the Teradata Database MPP instance include:
  • Teradata Data Mover
  • Teradata Data Stream Controller
  • Teradata Ecosystem Manager
  • Teradata REST
  • Teradata Server Management
  • Teradata Viewpoint
