View PostAntivirus Software: Ask the Hard Question
CIOs and IT managers care a very great deal about keeping the computer systems on their networks free of viruses. Most don’t concern themselves with the details of antivirus strategy.

View PostAntivirus Developers Dropped the Ball: PDF Is Not a Surprise
AV vendors once again claim to be “surprised” by an attack vector they should have expected. A new complaint is running rife in the antivirus community, this time about PDF and Adobe Reader, the new frontier for viruses, worms and other cyber creepy-crawlies.

View PostFlubbed Redaction Makes Headlines…Again
Some secrets are trivial, some are critical. It’s probably a matter of perspective, but failing to redact key information from sensitive military memos on nuclear submarine operations would tend to fit most definitions of “critical”. Ignorance of basic realities about computers and the lack of proper procedures for releasing information is a toxic combination for […]

View PostPDF and HTML: Objects and Semantics
Let’s step back a moment, and get metaphysical about electronic content. Can we do that? Whatever else they might possess, electronic documents always possess two things: objects and semantics. Document “objects” are the physical characters, images, lines, bullets and other features that consume ink or toner when printed. Document “semantics” define the logical relationships between the aforementioned objects. Most […]
View PostPDF Standards in Real Life
PDF is one of the most common file-formats on the planet. Why is it so pervasive? Why is it PDF that serves mankind as the undisputed universal electronic equivalent of paper, and not some other technology? A large part of the answer lies in the fact that PDF is extraordinarily sophisticated; clever and robust enough to […]
