Second day away from my family

This is the second day I have been away from my wife (excepting when the kids were born) since we were married almost 13 years ago…  It’s quiet, somewhat peaceful, but definitely lonely!

I have only been without the children (except for births) a few times in their whole life, and except for births, it was because we went to Haiti. 

 

The totality of being without my wife and children is very strange – it’s definitely quiet, peaceful, and interesting to not have such weight pressing down (additionally due to the fact that I am not at home, so the million chores that I need to do aren’t on my mind constantly) – but I can say with certainty that it’s not anything I’d like to practice long term… well, maybe a few more breaks from the kids would be nice!  😉

CBK 4 – Physical Security

I am now well versed in fence heights, and chain diameters, fire extinguishers, and IDS systems.  My score was actually higher than this too – as I found at least one bug in the testing software where it said my answer was the correct answer, but then marked it wrong :-0

Another one down – Security Architecture

This was probably the most extensive learning I had to do so far in the CISSP around the different security Models, like the Bell-LaPidula, the Biba, the Clark-WIlson, the Graham-Dennig and the Harrison-Ruzzo-Ulllman security Models… you have all that right? LoL

Funniest part is, I scored almost 100% on almost all of the concepts except:  I couldn’t seem to make the distinction between multiprocessing, multiprogramming, mutithreading and multitasking – how lame is that!

Oh, and I was exposed to a very cool side-channel attack (or more appropriately called a covert storage attack) having to do with information flow.. with an example of using storage state (like files being locked and unlocked) to steal data one bit at a time… that was pretty neat thinking!

Anyway – after 120 pages of very extensive reading under Security Architecture – I’m off to the next CBK starting tomorrow.

Access Control CBK

I read over a 100 pages last night, and there was SO much information and acronyms galore!  I have a really good understanding of Access Control, but I still learned a bunch! 

I have to do school reading tonight, so I’m going to unfortunately be behind now in the CISSP review, but I’ll have the weekend to try and catch up!

Oh, and I found out that I can read SO much more a night if I shut down my computer and put it away!  There is too much tempting me on the computer to actually keep me from peaking and playing every couple minutes…  I need better attention skills!  LoL
