Fortify your RMM Central server

Security Recommendations

RMM Central is a holistic remote monitoring and management tool for MSPs that manages your client networks and devices, and helps you automate your complete client IT management from a central location. In this document, we will provide you with some tips and tricks to harden your RMM Central security.

Best security practices

RMM Central immediately releases the security patches for identified security issues. Follow the Security Updates Group to stay updated with the latest security patches. Furthermore, please subscribe to our Data Breach Notification to receive notifications on any security incident without delay.

Note: It is highly recommended to
1) Update your RMM Central server to the latest build.
2) Grant access to the RMM Central folder only to authorized users.
3) Use proper firewall and Anti-virus software and keep them up-to-date to get accurate alarm.
4) Delete unused user accounts from RMM Central server's product console and from the machine where the RMM Central server is installed.
5) Install distribution server in a dedicated machine with no other third party software in it. Only Authorized users should have access to this machine.

Secure the access to RMM Central

Securing the login access to RMM Central, can prevent security issues involving roles and permissions.

Security Settings

Basic

  • Subscribe to security advisory in-product

    Configure email address to receive security advisories from Endpoint Central.

  • Enable notification for security recommendations

    Get personalized Central server hardening recommendations via email.

  • Remove default admin account

    The default admin account should be removed after the first login.

  • Enable secure communication (HTTPS) for Central Server.

    This setting will enforce your Endpoint Central Server to accept responses that are in HTTPS mode only.
    Note: In addition, disable the 8020 port in firewall in your network

  • Enforce two-factor authentication

    Have a second level of verification for technicians to ensure unauthorized access is prevented.

  • Restrict users from uninstalling the agent from control panel

    The agent monitors and executes the configurations and tasks deployed to a particular endpoint. That's why it is necessary to forbid users from uninstalling the agent.

  • Restrict users from stopping agent service

    Preventing the users from stopping the Agent service ensures that the endpoint stays in contact with the server every 90 minutes.

  • Enable secured communication (HTTPS) for LAN and WAN agents

    HTTPS protocol for both LAN and WAN agents ensures that the communication between the agents and the server is always encrypted.

Advanced

  • Use third-party SSL certificate

    Configure Endpoint Central with a trusted third party certificate to ensure secured connections between endpoints and servers. However, for secured communication using HTTPS, a default certificate will be provided along with the server.

  • Disable the older versions of TLS

    For improved security, it is advisable to use the newer version of TLS, instead of using the older ones.
    Note    : Users cannot manage devices running on legacy OS platforms (Windows XP, Vista, Server 2003 and Server 2008) after disabling the older version of TLS.

  • Use Secure Gateway Server

    It is highly recommended to host the Endpoint Central server in a corporate network protected by firewall restrictions and other security measures. If there are several roaming users and remote offices, then you can use an additional component, called the Secure Gateway Server. Secure Gateway Server is a reverse proxy solution that acts as a bridge between the WAN agents and the Endpoint Central server. It prevents the need for the Endpoint Central server to be hosted as an EDGE device to manage roaming users.

  • Enable agent-server trusted communication

    Secure the communication between Central server and agents by enforcing identity verification during HTTPS communication. It can be enabled only after importing a third-party certificate. Learn more.

  • Enable certificate-based authentication for agent-server communication

    Enable client certificate authentication to validate the authenticity of agents that try to establish a connection with the server. Before enabling, ensure the agent versions are up-to-date, as older agents will not be able to connect with the server. Learn More.

  • Secure your database backup

    Configure this to encrypt the scheduled database backup with a password.

  • Secure software repository (Local network share)

    The local network share will contain all the software installation files. Access credential is use to grant access to the share to authorized users only.

Module-wise methodical steps to enhance security:

General

Miscellaneous

Software Deployment

Configuration

  • Provide the root access only to trusted technicians in Redhat nominated machines to avoid sending malicious content, instead of meta files.
  • Provide the root access only to trusted technicians in Linux agents to avoid sending malicious URLs, instead of package URLs.
  • Scan the uploaded files in the Upload Patch option for any malicious files.

  • Enrollment settings

    • For enrolling corporate-owned devices, use the following enrollment methods based on the supported platforms to ensure devices always remain under management even after being factory reset:
    • On corporate devices, the options to perform a factory reset and device wipe can also be restricted to prevent users from removing devices from management.
    • For Android devices, the Allow User to remove ME MDM App option should be disabled to restrict corporate devices that have not been enrolled using the above mentioned enrollment methods from being removed from management.
    • Enable the option to detect and remove jailbroken and rooted devices to ensure only compliant devices remain under management and access corporate data.

  • Inventory settings

    • Schedule regular device scans to ensure the device details remain up to date.

  • Device settings

    • Configure Device Privacy Settings to ensure only the details required by RMM Central for management and only the data permitted by the local and global compliance laws are stored on the server.
    • Configure the Terms of Use policies to be displayed to the device users and obtain their consent before collecting and storing device information on the RMM Central server to ensure user privacy.
  • Go to the Admin -> UEMtab, under Tools Settings,
    click Port Settings and switch the Communication to HTTPS. Click Save.
  • click System Manager Settings.
  • Under Permission Settings, enable the permission to access the end user's File Manager and Command Prompt to only admins.
  • Under User Confirmation Settings, opposite to the Enable user confirmation for field, check the boxes for File Manager and Command Prompt.
  • Now, go to the UEM -> Tools tab, click Remote Control, and switch to the Settings tab. Here, enable the Idle Session Settings. This allows the remote connection to either just disconnect or disconnect and lock the target computer automatically, when the connection is idle for a set period.
  • In the Remote Control tab, switch to the User Confirmation tab. Here, enable User Confirmation, set a time out period and provide a confirmation message. You can also Make User Confirmation Permanent. Click Save.
  • Note: After enabling the Make User Confirmation Permanent option, the confirmation dialog box will always be displayed and this cannot be reverted even by administrators.

    Go to the Admin -> UEM tab,

  • under Database Settings, click Database Backup. Here, schedule a time at which the database should back up every day. You can also set the number of backups to be stored, beyond which the backups will be deleted automatically. It is highly recommended to receive notifications about the database backup failure. Furthermore, secure the database backup using a password.
  • under Customers, click Agent Settings. Here, enable the Restrict users from Uninstalling the Agent from Control Panel and the Restrict users from stopping Agent service options.
  • under Security Settings, click Export Settings. While exporting any reports, you can:
    • Mask the personal Information
    • Remove personal Information
    • Retain Personal Information
    • Let the Technician Decide
