Hello S Siva1,
Thank you for posting in Microsoft Community forum.
It sounds like you're dealing with a specific vulnerability identified by Tenable on your Active Directory (AD) servers. While I don't have direct access to Tenable's database of plugins, here are some general advice on how to address vulnerabilities on AD servers based on common practices.
1.Review the Scan Report:
First, carefully review the details provided by Tenable for plugin ID 150480. The report should contain specific information regarding the nature of the vulnerability, affected components, and perhaps even remediation steps.
2.Patch Management:
Ensure that your AD servers are up-to-date with the latest patches and updates from Microsoft. Vulnerabilities are often addressed by applying the latest security patches.
3.Configuration Changes:
Secure LDAP (LDAPS): If the vulnerability is related to LDAP, consider configuring your AD servers to require LDAPS for secure communication.
Group Policies: Review and, if necessary, tighten your Group Policy settings to enforce stronger security settings.
Administrative Permissions: Limit admin permissions to only those who absolutely need them and ensure that accounts with administrative access follow best practices for password complexity and multi-factor authentication.
4.Firewall and Network Settings:
Ensure that your AD servers are protected by properly configured firewalls, and limit access to these servers to only necessary systems and users.
5.Auditing and Monitoring:
Implement and regularly review auditing and monitoring on your AD servers to detect and respond to suspicious activities quickly.
6.Disable Unused Services:
Disable any unnecessary services and features that might be increasing your attack surface.
7.Backup:
Regularly back up your AD servers to ensure you can recover quickly in case of a security breach or other failure.
For a more specific solution, you would need to look at the detailed information provided by Tenable.
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
