What is MPLS (Multi Protocol Label Switching)?
MPLS (Multi Protocol Label Switching) Challenges of MPLS (which helped drive the push to SD-WAN): Expensive connectivity Long time to deploy (60, 90, 120 days plus lead time) Cloud & mobile access are neglected Internet performance & availability Security Management With the old, pre-SD-WAN: ’Hub & Spoke’ topology Branches communicated with the hub & the data center Internet access was typically centralized out of the Home Office Cloud internet went thru Headquarters MPLS gave up predictability & availability Backhauling internet traffic to the Data Center for security consumes a lot of expensive MPLS bandwidth and it often means added latency. (The “trombone effect”!) MPLS circuits are expensive.

What is Access Control?
Traditional computer security revolves around access control. “It is where security engineering meets computer science.” —Ross Anderson, Security Engineering Access control is to control whom or who, has access to which resources in a system. Access control works at a number of levels from Hardware at the base, up through the Operating System, then Middleware, and up to the Application level. “As we work up from the hardware through the operating system and middleware to the application layer, the controls become progressively more complex and less reliable.” —Ross Anderson, Security Engineering Complexity tends to be at opposites with security. “Now now of the biggest challenges in computer security is preventing…
