Ensure there is no unrestricted inbound access to TCP port 2382 (SQL)

Security & Compliance
No items found.

TCP port 2382 is used by SQL Server Analysis Services for client/server communication over TCP/IP. By default, this port is not secured, and if it's left open, it can allow unrestricted access to the SQL Server Analysis Services. This could potentially lead to unauthorized access, data breaches, or denial-of-service attacks.


To ensure there is no unrestricted inbound access to TCP port 2382, network administrators should implement the following security measures:

  1. Close the port: If the port is not needed for any legitimate business purposes, it is recommended to close it completely to prevent unauthorized access.
  2. Configure firewalls: Configure firewalls to block all incoming traffic on TCP port 2382, except for the trusted sources or IP addresses that are allowed to access the service.
  3. Use VPN: If remote access to the SQL Server Analysis Services is necessary, use VPN (Virtual Private Network) to establish a secure connection to the network.
  4. Enable encryption: Configure SQL Server Analysis Services to use encryption for all client-server communication. This will help protect against man-in-the-middle attacks and eavesdropping.
  5. Regular vulnerability scans: Regularly perform vulnerability scans to identify any open ports or security weaknesses that could be exploited by attackers.

Note: Remediation steps provided by Lightlytics are meant to be suggestions and guidelines only. It is crucial to thoroughly verify and test any remediation steps before applying them to production environments. Each organization's infrastructure and security needs may differ, and blindly applying suggested remediation steps without proper testing could potentially cause unforeseen issues or vulnerabilities. Therefore, it is strongly recommended that you validate and customize any remediation steps to meet your organization's specific requirements and ensure that they align with your security policies and best practices.
