Page 27: Appendix 1 Cybersecurity Recommendations
Appendix 1 Cybersecurity Recommendations Cybersecurity is more than just a buzzword: it’s something that pertains to every device that is connected to the internet. IP video surveillance is not immune to cyber risks, but taking basic steps toward protecting and strengthening networks and networked appliances will make them less susceptible to attacks. - Page 28 6. Enable HTTPS We suggest you to enable HTTPS, so that you visit Web service through a secure communication channel. 7. MAC Address Binding We recommend you to bind the IP and MAC address of the gateway to the device, thus reducing the risk of ARP spoofing.
