20:31 The digital acceleration that is sweeping across organizations has resulted in millions of new IP-based devices getting connected to the network. And the benefits to productivity, efficiency, and flexibility driven by cloud-based analysis has opened up a whole new landscape that is ripe for attack. Wired and wireless networks need to adapt to this reality by having native features to address security. In the same way that zero trust principles are being applied to how users access applications, organizations need to be able to provide the same zero trust principles to the non-user associated devices.
The zero-trust security model is based on the principle that every device or user is potentially compromised, so every access request must be authorized. When the zero-trust approach is applied to corporate campus networks (Ethernet and Wi-Fi) it often works in concert with network access control (NAC) solutions, which ensure that only devices that should attach to the network do. However, this can lead to complexity. What’s needed in this time of digital acceleration is the integration of NAC functionality into the very fabric of the wired and wireless networking equipmentto restrict what networked devices can access.
