Can’t I trust the Postal Service? Part 1 – the crypto.

The Security MVPs have a private mailing list on which we gather to share expertise or our interesting findings – the following was raised by an MVP, and very much interested me, on a number of levels: The US Postal Service has a web service (as well as a physical method) for signing up to […]

I’m still not that into Apple

Apple Updater showed me two new software updates the other day – “Quicktime” and “iTunes + QuickTime”. Now, remember, I never installed iTunes, and went out of my way to install only QuickTime.

NULL DACL Behaviour in Windows Vista

Filed under: General Security,TechEd,Windows Vista @ 9:45 pm

  Subtitled: Don’t believe everything you hear at TechEd. I was inspired by my “empty DACL” issue, and what I remembered of Jesper’s “Is That Application Really Secure?” talk from last June’s Microsoft Tech-Ed conference, to test whether my security issue was caused by a NULL or empty DACL. Jesper had said in his talk […]

Vista incompatibility isn’t always Vista

In fact, it is very rarely Vista, from the problems I’ve seen. Sure, there are some programs that rely on features and functionality that has been removed from Vista – but by and large, that functionality was already documented by Microsoft as being ‘deprecated’ or ‘obsolete’. [Some features documented as obsolete for a decade!] In […]
