I personally see that the mac is getting lots and lots of love! Not my place to say more than that. I pointed to this resource due to the concern expressed about iOS.

I designed and implemented quite lot of the LocalKDC mechanism - um, roughly about 11-12 years ago now I think. At the time it was based on the MIT version of Kerberos. When Apple switched to using Heimdal, the LocalKDC implementation was u

Yes! Touted on the cover as the "1st & last edition". There are two versions of page 111, with an apology (and an apology for the apology) if you thought the first was offensive. There is also Illustrating Basic (1977) and Ill

I migrated about a year ago from using net4801s to Ubiquity EdgeRouter Lite devices. The EdgeRouter Lite has 3 Gigabit ethernet ports. I got to keep my network topology and the software was flexible enough to mostly configure it how I wante

The "home security system" calls could be social engineering to find out if your home is protected or not. Just by listening to what they say and not saying you already have one is enough to tell the caller what they want to know.

I may have made a mistake in assuming that the vertical line, because it was drawn in a different weight, was not part of the symbol. Without the line 1 & 4, 2 & 8 and 3 & 12 would rely on the vertical relationship with other sy

I think there is a problem with this notation - it is not self aligning. Meaning that if you hand wrote these you could then easily mis-read the values. It would probably be okay in printed form or if you were using lined paper, using the

You can already sort of do this. But it is done with drag-n-drop. Pick a file on your Desktop and drop it into a Screen Sharing window! Drag a file from a Screen Sharing session onto your desktop.

This logic is flawed. If you want to test something secretly you do it in plain sight and use mis-direction. Buy some Tesla vehicles and put your electronics inside -- can you tell who owns the software and hardware inside when looking at t

A couple of errors near the end for "How Many Hosts Were “Up” Last Month But Now It’s “Down”" and vice versa. The error is that using xor on the same item twice is a no-op... (A xor B) xor A == B. The correct equations would be,

It sounds like a great idea, but thieves might want to own the servers that store this data. On these servers will be a list of products and because of the receipts, very likely the physical address of where they were shipped to and how new

This is complete rubbish. Apple software updates have been digitally signed since Tiger, OS X 10.4. It doesn't matter who sends you the bits, if the signature doesn't validate, the software will not install. See http://

As a, possibly self proclaimed, security expert I'm not particularly impressed with the blog posting. Why? The premise is that Computer Security is a pinnacle and now the protagonist is looking back, it looks a bit lame and has a feel

And to do that you must also transmit the escrowed part of the key in the protocol -- which is 100% detectable as a blob of " extra but seemingly unnecessary data". Do you see that? Does anybody see that? Has anybody seen tha

Skipjack is dead, extinct. If this were true, it would be possible to find it by disassembling iOS. There would also be a suspicious "unexplained" payload that accompanied anything that was encrypted with a symmetric key.

Future messages would need to be encrypted using the new key. If the protocol announces when a new key is added to the "encryption set" how can you get away with that? (when you add a new device to iMessage all the other devices &

There is a prevailing assumption that this problem is "caused" by bad software. This might be the case, but bad hardware could also be part of this! A lot of modern hardware has programmable parameters, "core voltages", PLL parameters that

Nope, it isn't an overreaction. It isn't hypocrisy either. You appear to have confused the difference between active and passive involvement in a conversation. The tweets were an active response. The problem was directing a "suggestive" / "
