History of Networking: Stan Hanks and GRE

The 4D Network

I think we can all agree networks have become too complex—and this complexity is a result of the network often becoming the “final dumping ground” of every problem that seems like it might impact more than one system, or everything no-one else can figure out how to solve. It’s rather humorous, in fact, to see a lot of server and application folks sitting around saying “this networking stuff is so complex—let’s design something better and simpler in our bespoke overlay…” and then falling into the same complexity traps as they start facing the real problems of policy and scale.

This complexity cannot be “automated away.” It can be smeared over with intent, but we’re going to find—soon enough—that smearing intent on top of complexity just makes for a dirty kitchen and a sub-standard meal.

Thousands of people graduate from colleges and universities each year with cybersecurity or computer science degrees only to find employers are less than thrilled about their hands-on, foundational skills. Here’s a look at a recent survey that identified some of the bigger skills gaps, and some thoughts about how those seeking a career in these fields can better stand out from the crowd.

Three standards for email security that are supposed to verify the source of a message have critical implementation differences that could allow attackers to send emails from one domain and have them verified as sent from a different — more legitimate-seeming — domain, says a research team who will present their findings at the virtual Black Hat conference next month.
