Network Break 400: Ex-Cisco CEO Launches Network Startup; The Persistence Of Floppy Disks
Take a Network Break! On this week’s podcast we cover Nile, a networking startup backed by former Cisco CEO John Chambers. Palo Alto Networks may be eyeing a cloud security startup for purchase, and US government agencies would like service providers to implement BGP security.
SASE growth surges in Q2 2022, satellite operators want more than five years to get decommissioned satellites out of orbit, and a small outfit is doing good business as the last floppy disk store standing.

Tech Bytes: Palo Alto Networks Enhances AIOps For Prisma SD-WAN (Sponsored)
Today on the Tech Bytes podcast we talk with Palo Alto Networks about the latest AI Ops features for SD-WAN. AI Ops is a broad term for software that analyzes network data and then makes recommendations on issues and problems. This proactive capability has become necessary as network complexity grows to encompass underlays, overlays, on and off-prem cloud destinations, remote working, and …. well, everything.
Our guest is Bill Pruitt, Senior Product Management, SASE, at Palo Alto Networks.

Heavy Networking 648: Using Zero Knowledge Middleboxes To Enforce Policy On Encrypted Traffic
If you use a middlebox such as a firewall or proxy to enforce security policies on network traffic, you’re well aware of the problem of pervasive encryption. If the middlebox can’t read the data stream, how can policy be enforced?
The usual answer to this was to give a proxy keys so it could be a man in the middle of an encrypted session, at least for those few hosts you have the keys for. But as most of the traffic you want to inspect isn’t heading to a server you control, the man in the middle approach isn’t viable most of the time.
And that’s especially the world we live in today, where the payload of everything from web to chat to DNS queries is probably encrypted. Our middleboxes can’t see what’s inside to protect us from the bad stuff.
But what if there was a way a middlebox could still accurately enforce policy on encrypted traffic? That’s the research Paul Grubbs has been working on as an Assistant Professor at the University of Michigan. He wrote about “Unpacking Zero Knowledge Middleboxes” on the APNIC blog in July 2022, and we’re chatting with him about zero knowledge middleboxes today.
* Paul and his team’s research in zero knowledge middleboxes
* How encryption can impact security policy enforcement
* Using cryptographic verification between clients and middleboxes for policy enforcement
* Use cases such as DNS
* Practical implications and potential drawbacks

IPv6 Buzz 110: The Peculiar Power Of DHCPv6 Option 108
On today’s IPv6 Buzz podcast, Scott and Tom talk about DHCPv6 Option 108. Option 108 basically allows a DHCP server to use IPv4 to contact a host and tell that host to disable its IPv4 stack and switch to IPv6-only. In other words, you’re using IPv4 to turn off IPv4. This peculiar capability is proposed in RFC 8925: IPv6-Only Preferred Option for DHCPv4.
* DHCPv6 Option 108 and what it does
* Operational use cases for this option
* Current OS support
* Using Option 108 to turn off IPv4 for short intervals instead of permanently
* How Option 108 fit into the larger picture of DHCPv6 in particular and IPv6 auto-addressing in general

Day Two Cloud 164: DevSecOps Is A Real Thing
Today on the Day Two Cloud podcast, we talk DevSecOps and how it’s more than just a marketing term. We also discuss Infrastructure as Code (IaC) and IT as Code and what that actually means for operations folks. It doesn’t mean you have to write code all day, but we make an effort to put some specifics around what an Ops person should know when it comes to code.
Our guest is Mike Fraser, VP of DevSecOps at Sophos.
