How to Determine Network Security

Networking is the backbone to any IP video project. Insufficient bandwidth, unsecure devices, and slow legacy protocols can render even the best cameras and servers inoperable. BCDVideo Networking Engineer Michael Wagner discusses networking’s importance and best practices for securing your entire network.

Why Networking is Important

Networking is the glue that holds everything together. Without a proper network infrastructure, individual devices like recording servers, client viewing stations, and IP cameras act independently. Networking allows all of these devices to seamlessly communicate while giving system administrators the ability to view the data locally or remotely.

Network Security Best Practices

Vulnerable networks expose entire systems to malicious activity. There are several security best practices to follow:

  • Strong alphanumeric passwords – never use the default password
  • Use secure protocols for administrative purposes
    • SSH
    • HTTPS
    • SNMP v3
  • Physically secure the server room

How to Secure Traffic Isolation

The use of virtual local area networks (VLANs) will segregate all data communication. This allows critical business and surveillance chatter to remain separate. Isolating video surveillance networks from data networks ensures quality of service and intercommunication issues never hamper your overall system health. Next generation technology like Layer-2 and Layer-3 VSNs is also becoming more widely used.

How to Optimize your Current Network

The first thing to look for when optimizing your current network is sufficient bandwidth. Can your system handle the amount of data required? Not only do you need bandwidth to support all of your devices, there should be enough to allow for future system expansion.

Additionally, the settings on your IP cameras need to sync with the settings on your recording server e.g., resolution, frames per second, etc.

Networking and Physical Security

Access control like biometrics, smart card readers, and door locks can be sabotaged by a hacked network. Proper network security is crucial to maintaining the features and functionality of your physical security.

Establishing a strong foundation for network security boils down to three key areas:

  1. Confidentiality – Is your network being accessed by users who have been authenticated and authorized to access it?
  2. Integrity – Is your network data the same from source to destination?
  3. Availability – Is data transmission from my network available when I need it, where I need it, and how I need it?

If you can answer “yes” to all three, you’ve established a strong foundation for network security.
