Office network and Wi-Fi: why one flat network is a risk
Guests, cameras, printers and the accounting server on the same network? Segmentation stops one infected device from reaching everything.
Read articleVideo surveillance is installed to increase security, yet IP cameras and video recorders are among the most frequently hacked devices. They often keep default passwords, are rarely updated and are opened to the internet for remote viewing.
Common mistakes
- Default or simple passwords on cameras and the recorder (NVR/DVR).
- Port forwarding on the router to watch cameras from a phone.
- Firmware that has never been updated since installation.
- Cameras in the same network as accounting and servers.
How to secure it
- Set unique strong passwords and remove unused accounts.
- Put cameras and the recorder in a separate VLAN without internet access, if possible.
- For remote viewing use a VPN instead of open ports or unknown cloud services.
- Update firmware regularly and choose vendors that publish security updates.
- Restrict who can view and export recordings, and log access.
A camera should watch the office — not let strangers watch it.
