This is the worst security. It was done this way for the sake of <br>
simplicity. Our netops volunteers had to get up to speed with <br>
unfamiliar concepts like routing, funky netmasks, dynamic routing <br>
protocols, policy routing, VRRP, firewalls, MTUs, MSS control, IPsec, <br>
etc. We reaped the rewards of KISS from broader volunteer engagement, <br>
but lately we've been paying too heavy of a price for the awful security <br>
this simplicity creates. In the most recent breach we've lost important <br>
source code that will now need to be re-created. We escaped total <br>
disaster by the thinnest of margins, as one critical hypervisor just <br>
happened to be patched to 1 version higher than exploitable. This <br>
simplicity is not a good tradeoff anymore, so the time has come to <br>
introduce more complexity to the network to protect all control points.<br>
<br>
This is not a simple problem, since there are many fragility vs security <br>
tradeoffs, as well as complexity cost concerns. If you have experience <br>
or thoughts around this area, and can commit to a few weeks of design <br>
and implementation work on this project, please indicate your interest. <br>
We'll assemble a small working group in the next few days and start <br>
discussions. I expect the working format will involve some virtual <br>
meetings, since email is not high bandwidth enough to hash out <br>
everything quickly.<br>
<br>
Here's hoping we don't make it worse,<br>
