When it comes to redaction, any help is good help
When John Landwehr, Adobe's security director, visited GCN recently, he promised a white paper on proper redaction techniques. Because although it's rarely due to a faulty Adobe product when a government official inadvertently leaves poorly (or not even) redacted information in a file they convert to PDF, it starts to reflect badly on Adobe when news stories
mention PDF in connection with data leaks.
The other day Landwehr dropped us an e-mail saying the white paper is now available
. It's called "Redaction of Confidential Information in a Document" (could have used an editor to punch up that title), and it's laser-focused on Microsoft Word. There's plenty of illustration and hand-holding, which is to say it's an effective paper--with its own digital signature so you know it comes from the source.
Adobe gives a nod to similar National Security Agency guidance that came out in December. GCN's Joab Jackson described NSA's advice and others' in a recent story
Landwehr himself maintains a very informative blog
on information assurance issues. It's worth checking out.Posted by Brad Grimes
