VNC traffic is not encrypted by default, which means that your password and data could be intercepted if someone is monitoring your network. To address this, use encryption to protect your VNC connections. One common method is to use SSH (Secure Shell) tunneling. SSH creates an encrypted tunnel between your client and server, protecting the VNC traffic from eavesdropping. You can set up an SSH tunnel using a tool like PuTTY on Windows or the built-in SSH client on Linux and macOS. Another option is to use a VNC server that supports encryption natively, such as RealVNC. Encrypting your VNC connections is a critical step in securing your remote access.
Network Segmentation and Firewalls
Consider segmenting your network to isolate your IoT devices from your main network. This can help prevent a security breach on one device from spreading to others. You can do this by placing your IoT devices on a separate VLAN (Virtual LAN) or subnet. Additionally, use firewalls to control network traffic and restrict access to your VNC server. Only allow connections from trusted IP addresses or networks. Configure your firewall to block any unauthorized access attempts. By implementing network segmentation and firewalls, you can create a more secure environment for your IoT devices and minimize the risk of external attacks. These security measures are essential for maintaining the integrity and confidentiality of your IoT deployments.
