Study Notes
- Remote desktop connections enable viewing and controlling a desktop across a network.
Remote Desktop Protocol (RDP)
- Microsoft's RDP is commonly used for connecting to Windows devices, but clients are available for other OS like Mac OS and Linux.
- Open TCP port 3389 indicates a system is listening for an RDP connection, making it a target for attackers.
Virtual Network Computing (VNC)
- VNC is another technology that is similar to RDP for Mac OS and Linux.
- VNC uses RFB (Remote Frame Buffer) protocol for remote desktop communication.
- Clients for VNC are available on many operating systems (including Windows) and are often open source.
- Security concerns with VNC and third-party remote desktop systems arise from reliance on usernames and passwords.
Virtual Private Network (VPN)
- VPN creates an encrypted link between a device and a central concentrator, commonly used for remote work.
- A VPN concentrator handles encryption and decryption of VPN tunnels and can be a standalone device or integrated into a firewall.
- VPN client software can be configured for on-demand or always-on access.
- VPNs use strong encryption, attackers focus on endpoints to gain access to the network.
- Multi-factor authentication (MFA) adds security via a code from a phone, alongside username/password.
Secure Shell (SSH)
- SSH is used by server administrators to remotely administer servers over network.
- SSH is an encrypted protocol for secure command-line communication.
- SSH encrypts data, attackers can't understand the packets.
- SSH allows the use of public/private key pairs for authentication, adding a layer of security.
- SSH can be configured to control which accounts and IP addresses can log in.
Remote Monitoring and Management (RMM)
- Managed service providers (MSPs) use RMM for constant network monitoring of customer network and remote devices.
- RMM enables patching OSs, logging into customer's devices, monitoring anomalies, and providing hardware/software inventory.
- Strict security controls, authentication, and ongoing audits are crucial for RMM due to access it grants to customer networks.
Microsoft Remote Assistance (MSRA)
- Microsoft Remote Assistance (MSRA) offers on-demand remote access and does not need firewall configuration or port forwarding.
- The user needing help initiates MSRA and sends an invitation file to the technician.
- The technician opens the invitation to connect.
QuickAssist
- QuickAssist is a newer version of MSRA available in Windows 10 and 11 that streamlines the remote assistance process.
- MSRA/QuickAssist do not run constantly in the background eliminating unauthorized access risks.
- Sharing the code via phone call is more secure.
Third Party Tools
- GoToMyPC and TeamViewer offer remote control functionality.
- Zoom and Webex are used for video conferencing.
- Dropbox, Box.com, and Google Drive are cloud-based file transfer tools.
- Citrix Endpoint Management and ManageEngine Desktop Central are used for managing end-user devices.
