Couldn’t Resist: Cheat-Proofing Certifications
Stumbled upon this paragraph on Russ White’s blog:
I don’t really know how you write a certification that does not allow someone who has memorized the feature guide to do well. How do you test for protocol theory, and still have a broad enough set of test questions that they cannot be photographed and distributed?
As Russ succinctly explained the problem is two-fold:

Measuring ATR
One of the more pressing and persistent problems today is the treatment of fragmented packets. We are seeing a very large number of end-to-end paths that no longer support the transmission of fragmented IP datagrams. What can the DNS do to mitigate this issue?New Research: Organizations Overhauling IT Will Leapfrog Competition

Mythology about security…
Ed Felton tweeted a few days ago: “Often hear that the reason today’s Internet is not more secure is that the early designers failed to imagine that security could ever matter. That is a myth.”
This is indeed a myth. Much of the current morass can be laid at the feet of the United States government, due to its export regulations around cryptography.
I will testify against the myth. Bob Scheifler and I started the X Window System in 1984 at MIT, which is a network transparent window system: that is, applications can reside on computers anywhere in the network and use the X display server. As keyboard events may be transmitted over the network, it was clear to us from the get-go that it was a security issue. It is in use to this day on Linux systems all over the world (remote X11 access is no longer allowed: the ssh protocol is used to tunnel the X protocol securely for remote use). By sometime in 1985 or 1986 we were distributing X under the MIT License, which was developed originally for use of the MIT X Window System distribution (I’d have to go dig Continue reading
Privacy-Protecting Portable Router: Adding DNS-Over-TLS support to OpenWRT (LEDE) with Unbound
If you want to skip ahead to instructions, scroll to the next section. But I, like a TLS handshake, am very verbose so please enjoy this opener.
Imagine this scenario - I'm at a restaurant and need to have a private phone conversation but unfortunately my phone's battery is drained. To get around this problem, I borrow my friend's phone and dial the number - to protect my privacy I walk outside. When I'm done with the call, I come back inside and return the phone.
Whilst the phone itself doesn't store the coversation I've had, it does have a log of the recently dialed number, if the friend from whom I borrowed the phone wanted to, they could easily see who I actually called - even if they don't specifically know the topic of conversation.
Sometimes, the data about who you've spoken to can tell an aweful lot about the conversation - if someone was to call an emotional support hotline or a debt collector, you could probably infer a lot about the conversation from the caller ID.
When we browse the internet, we use encryption to try and protect the conversations we have. When you connect to a Continue reading
