Code42 User Directory Sync server hardening
Overview
To integrate your Code42 cloud environment with a directory service, you must configure User Directory Sync. This means installing the User Directory Sync tool to a dedicated server within your organization's environment as well as configuring the Code42 console. For directions, see Configure Code42 User Directory Sync.
The steps below provide best practices for implementing additional layers of security when deploying this tool in your environment.
Considerations
- To successfully run the User Directory Sync on a dedicated host, the computer must meet system requirements.
- Ensure your User Directory Sync installation is upgraded to the latest version.
- For help with User Directory Sync, contact your Customer Success Manager (CSM) to engage the Professional Services team.
Deployment options
Virtual server
You should deploy the Code42 User Directory Sync tool to a virtual server. Not only will this reduce your resources requirements, but then the tool is also abstracted from a physical machine. The virtualization hypervisor can be from any vendor so long as it supports:
- Network-based communication
- Java runtime
- 64-bit execution environment
Physical server
If you cannot deploy the Code42 User Directory Sync tool to a virtual server, instead deploy to a stand-alone, dedicated, minimal-resource server. Deploy the Code42 User Directory Sync tool to a different server than your Active Directory or LDAP server.
Networking
Inbound connections
This tool does not need to receive inbound connections from any service in order to run. As a result, inbound connections that are not necessary for management should be blocked using the operating system's firewall or a third party networking tool.
Outbound connections
The UDS tool will need to make outbound connections to Code42 and your directory server. Use encrypted ports whenever setting up these connections. The tool requires the following outbound connections are open:
|
Port |
Destination |
|---|---|
|
443 (HTTPS) |
Code42 cloud |
| 636 (LDAPS) | Your directory server |
Permissions
For any permission controls, follow the security principle of least privilege. This means that a person or process is given only the minimum level of access rights to complete an assigned operation.
LDAP bind user
The directory bind user should have read-only permissions to your directory, specifically within the search base for your target set of users.
OS service user
The operating system user account that will run the Code42 User Directory Sync tool should be given lowest-level permissions possible. The tool does not require administrative privileges to run.
Remote access user
No other users should be able to remotely access this server (SSH or RDP) other than an admin if required.
