TCP port 2383 is used by SQL Server Analysis Services for client connections. Allowing unrestricted inbound access to this port can potentially lead to unauthorized access, data exfiltration, and other security breaches.
Here are the remediation steps to ensure there is no unrestricted inbound access to TCP port 2383 (SQL Server Analysis):
- Determine if the port is required for business purposes. If it is not required, close the port.
- If the port is required, restrict access to the port to only those systems that require it. This can be done by creating a firewall rule that allows traffic only from specific IP addresses or subnets.
- Ensure that the systems that require access to the port are secured and configured according to industry best practices, such as having up-to-date patches and running only necessary services.
- Implement strong authentication mechanisms to restrict unauthorized access to the port.
- Regularly review and audit the access to the port to ensure that it is limited to only those systems that require it.
