How to improve security...?

Keep the server up-to-date: Ensure that the Windows Server operating system, applications, and other software are regularly updated with the latest security patches and fixes. Enable automatic updates whenever possible to ensure that the server is always protected against known vulnerabilities. Configure strong passwords: Enforce a strong password policy that requires users to create complex passwords and change them regularly. Implement multi-factor authentication (MFA) for remote access to the server. Limit user access: Grant users only the privileges they need to perform their job functions. Avoid granting administrative privileges to standard users. Harden the server: Use security configuration baselines such as the ones provided by Microsoft or third-party vendors to harden the server and minimize attack surface. Disable unnecessary services, ports, and protocols. Enable firewall: Enable the Windows Firewall or any other firewall solution to restrict inbound and outbound traffic to the server. Monitor the server: Implement security monitoring tools to detect and respond to security events in real-time. Configure and review server logs regularly to identify any suspicious activity. Backup and recovery: Implement a regular backup and recovery plan to ensure that critical data can be restored in case of a security breach or other disasters. Educate users: Educate users on the importance of security and provide regular security awareness training. Encourage users to report any suspicious activity immediately. By implementing these best practices, you can significantly reduce the risk of cyber attacks on your Windows Server environment.

Make sure all file system volumes use the NTFS file system, and configure file permissions to limit user permission to least privilege access. You should also install anti-virus software as part of your standard server security configuration, ideally with daily updates and real-time protection.
