NC #615 PAI, IPv6 and MAC Addresses, CMRA, Nag Companies About Security, Security Bits

I got to be on Clockwise again with Jason Snell, Dan Moren and Mikah Sargent. At CES, we interview Jessica Lane as she tells us about PAI Technologies interactive clay toys for kids and talk to CMRA about their camera band for the Apple Watch. I have a special Public Service Announcement urging everyone to nag companies if you see them doing things not as securely as you would hope. It features my father-in-law, who is my hero at pushing companies. Bart Busschots joins us for another scary episode of Security Bits.

PSA: Nag Companies About Their Security

Ken talks 1PasswordBecause of Bart I know I have a much better understanding of security and what I can do to keep myself more secure. My father-in-law, Ken, is one of my heroes, and he’s just as security conscious, if not more. You may remember him from the video, “Octogenarian Talks 1Password”. If you haven’t seen it, I put a link in the shownotes, it’s well worth watching and sharing with folks who think they’re too old to use a password manager.

This week he decided to take on Vanguard, the investment company. You see, they do these great webinars, but they deliver them in Flash. He’s been paying attention to Steve and me when we advise him, and he knows we purposely did not install Flash on his computer when we did a recent hardware upgrade for him.

He decided to take on Vanguard, the largest mutual fund company in the country. He started by writing to them and explaining that he was simply not going to put Flash on his newest computer, because he understood that it has a reputation for being compromised or hacked. A representative wrote back to him and said this: Continue reading “PSA: Nag Companies About Their Security”

IPv6 Link Local Addresses – 64 or 48-bit MAC Addresses?

In last week’s Chit Chat Across the Pond, I asked Bart to come during his off season to explain IPv6 to us. After the show aired, Kevin Jones DM’d me on Twitter and DJ made a comment on the blog, both with the same correction. One of the rules of this episode was that Bart only had a few days to learn the background himself so it was expected there might be errors. As always though, Bart is weird in that he actually likes to be corrected. Seriously,

Anyway, they were both commenting on this statement:

In IPv6, the host part is always 64bits long. This is conveniently the length of a MAC address.

They both explained that MAC addresses as we are used to seeing them, are 48 bits, not 64 bits.

Now this is going to sound a bit like explaining the tax code but I hope you’ll bear with me because there are a couple of parts here I think are interesting. First of all, Bart wasn’t technically wrong, but DJ and Kevin are more specifically correct.
