How to Secure Your Network (Don't Get Hacked!)
How to Secure Your Network(top)Many camera networks are insecure, even those installed by professionals. This guide gives basic instruction in how to secure a camera network from the most common types of attacks.
No Port Forwarding(top)Perhaps the most important rule of securing a computer network is to not forward ports to insecure services. I can put it no better than forum member nayr did in his "VPN Primer for Noobs" post:
Turn off UPnP(top)UPnP (Universal Plug and Play) is a "feature" found in routers which enables any device on your network to forward ports to itself without your explicit consent or knowledge. Find it and turn it off. Turn it off in your router. Turn it off in your modem. Turn it off in your NVR and in your IP cameras. Turn off UPnP wherever you find it.
Use a VPN(top)When you need to remotely access your NVR or cameras, use a VPN (Virtual Private Network). A VPN provides secure access control and encrypts all the network traffic it carries, making it ideal for accessing insecure services like video surveillance systems.
Many routers have VPN server functionality built-in. Asus routers, for example, are well-known for having built-in OpenVPN servers.
Again, I refer to the VPN Primer for Noobs thread.
