Securing all layers of a data center is extremely important. According to 2018 research conducted by the Ponemon Institute, the global average cost of a data breach is up 6.4 percent over the previous year to $3.86 million. Making logical security investments can help to ensure that IP security software, systems, devices, and anything that resides on a network are safe. Understanding the threats implicit in network streaming is step one. The main external threats include:
An adversary with access to the same network as two communicating devices can capture data packets. Any data — even sensitive and critical data — can be easily compromised if it is not protected.
A malicious computer can impersonate network resources luring the other part to expose sensitive information or altering the data.
An adversary that is able redirect and intercept traffic has the ability to alter the communication between two parties.
Compliance to industry standards is one of the main drivers for managing the transmission of network video. A common recommendation today is for all security data in transit over a network to be encrypted — and all resources should be authenticated. Securing network streaming requires implementing security for both the camera component and video management system, as well as the network infrastructure that those communication streams traverse. There are different levels of security when it comes to securing video being sent over IP networks. Convergint can implement Axis Communications and Genetec solutions to encrypt the data to ensure protection using Unicast or Multicast.
Unicast and Multicast
Unicast and multicast transmissions are two methods in which video is commonly streamed over a network, from the camera to its destination. Each video transmission method comes with its own pros and cons, and every installation’s functional requirements will dictate which transmission is best. In general, unicast streaming is the most common way to stream network video. Each client requests one media stream. This transmission ensures that all network packets are delivered to the client.
Multicast streaming broadcasts packets and allows multiple clients to view the same video stream. This is a more effective scheme when multiple clients view the same video stream. Multicast does not ensure that all clients will get all the packets due to network disruption. For video streams the impact may be very limited, often unnoticeable. The network infrastructure and system usage dictate which scheme to use.
