Token Authentication for Cached Private Content and APIs
While working to make the Internet a better place, we also want to make it easier for our customers to have control of their content and APIs, and who has access to them. Using Cloudflare’s Token Authentication features, customers can implement access control via URL tokens or HTTP request headers without having to build complex back-end systems.
Cloudflare will check these tokens at the edge before any request is relayed to an origin or served from cache. If the token is not valid the request is blocked. Since Cloudflare handles all the token validation, the origin server does not need to have complex authentication logic. In addition, a malicious user who attempts to forge tokens will be blocked from ever reaching the origin.
Leveraging our edge network of over 100 data centers, customers can use token authentication to perform access control checks on content and APIs, as well as allowing Cloudflare to cache private content and only serve it to users with a valid token tied specifically to that cached asset.
Performing access control on the edge has many benefits. Brute force attempts and other attacks on private assets don't ever reach Continue reading
Big Changes in 2017
This past June when I was in North Carolina at Cisco’s CPOC lab, I learned that there was a chance–albeit a slim one, but a chance nonetheless–that a position would be opening up on the CPOC team in the fall. By that point I had been to CPOC three times and knew many of the engineers who worked there. I spoke to them to get their feedback, met with the newly-hired manager of the team, and just generally did all the things I thought I should be doing to take advantage of my time being face to face with these folks.
Then I flew home, subscribed to the “new jobs at Cisco mailing list” and waited.
And then, one day, it was posted: CPOC Technical Projects Systems Engineer. I immediately sent a message to my wife who responded as only she knows how:
Five short interviews later I was offered the job!
This brings me to change #1: As of this month (January), I am no longer a Systems Engineer with Cisco Systems Canada. I am now a Systems Engineer on the CPOC team reporting to a manager in the US.
Beyond the basic level of Continue reading
