RIPE 86 Bites: What’s the Time?

A little appreciated aspect of our digital infrastructure is just how dependent we are on access to time. Disrupting the time base can not only lead to disruption in communications but can result in various forms of compromise of the integrity of communications. Accurate time was all but unobtainable for centuries, and then, as we spent significant sums devising even more accurate timekeeping instruments, accurate time became a specialized service. more

Trust and Insecurity

When I was first advocating home networking at Microsoft, we encountered a problem. The existing systems and applications had implicitly assumed they were inside a safe environment and didn't consider threats from bad actors.

The city of Morgan Hill and parts of three counties lost 911 service, cellular mobile telephone communications, land-line telephone, DSL internet and private networks, central station fire and burglar alarms, ATMs, credit card terminals, and monitoring of critical utilities..." more
