How to encrypt PDF files for free

Yesterday I wrote about the importance of encrypting documents before you send them via e-mail. But what if you don’t have a PDF creator, other than Microsoft Office or Open/Libre Office? It turns out you can encrypt PDF documents, including those you create with office software, for free–with caveats.

Certifications are a scam! A rebuttal

I overheard a couple of people talking a few weeks ago, and one said, flat out, “Certifications are a scam!” As one who has two security certifications (Security+ and CISSP), I disagree. Now that I’ve had my first post-CISSP professional review, I disagree even more strongly.

I’m tempted by this Nook deal

Kmart is selling the Nook Simple Touch–the e-ink, black-and-white version–for $70, which is nearly 30% off. I’m tempted. Very tempted. Tempted even to buy one and just use it as–drum roll–an e-reader. Disappointed in me?

End of the innocence for Mac security

Antivirus vendor Kapersky has identified a new trojan horse targetting Macintoshes.  It spreads a botnet based somewhere in China via an infected Microsoft Word document, typically sent as an e-mail attachment. The spin is that if you don’t use Word on your Mac, you’re safe. That’s true–this week. But going forward, it’s going to take […]

There’s a 61% chance the Adobe software you run at work is out of date

I read this week that 61% of Adobe Reader installations in workplaces is out of date. That’s very bad. Very, very bad. Because Adobe Reader is trivially easy to exploit, and there’s more sensitive information to steal on corporate PCs than there is on home PCs.

Pipe output straight to the clipboard in Vista and Windows 7

Besides all the changes to the GUI that happened post-Windows XP, they also made one useful change to the command prompt. It’s now possible to copy the output of a command to the clipboard. If you’re like me and write a lot of documentation, or you just take a lot of notes while doing computer […]

Happy Patch Tuesday, September 2011

Microsoft has five updates and Adobe has two for us on this fine Patch Tuesday, in addition to a patch Mozilla pushed out for Firefox last week. Don’t get too complacent if you run something other than Windows. If you run Microsoft Office on a Mac, or Adobe Reader or Acrobat on a Mac, or […]

How to view questionable PDFs safely

I said Tuesday that it’s a bad idea to download and view PDF (Adobe Acrobat/Adobe Reader) documents from questionable sources, but I didn’t really elaborate on why. The reason is that pretty much anybody with a little bit of determination and the ability to follow a recipe can plant a trap in a PDF file […]

Fide et fortitudine

Fide et fortitudine. That’s the motto on my family crest. It seems appropriate. If I didn’t have fidelity and fortitude, I wouldn’t be making this post, because I wouldn’t care. I’d talk about how to use Samba and Ghostscript and your favorite free Unix to set up a print server that spits out Acrobat-compatible PDF files or something.

Memoirs of writing a book

Book memoirs. I got e-mail yesterday asking me to reflect back on dealing with a publisher while writing a book. I’ll never talk publicly about specifics, and I’m not even positive how much I’ve told my closest friends, for that matter. But it got me thinking.
