Options for encrypting network
video streams
Compliance to industry standards is one of the main drivers
for network security and managing transmission of network
video. However, 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, video management system and
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. Hardening the
network involves establishing and maintaining authenticated
communication streams, digitally signing configuration files
and encrypting data and video streams and signaling between
all the various components. All of these security features are
not required for every network, but they provide options for
increasing levels of security.
Of course, each form of protection has a cost associated with
it and typically requires various workflow routines. Often, more
advanced routines are associated with more advanced forms of
protection, leading to escalating costs.
