Securely delete files on your Mac

| 0 comments

Deleting a file from your computer is like opening a book and scratching out the name of a chapter in the table of contents. The chapter isn’t really gone, just the information about how to find it is. To really wipe out the information in a book, you would turn to the chapter itself and scribble over the words until they were illegible.

| 0 comments

So far this year it seems just about every new day brings a new data breach. Now to be fair, I do not know how organizations are being breached, but I would tend to believe that SQL injection may be the culprit and this is just a simple suspicion on my part.

What can we learn from the 2013 Adobe database breach

| 0 comments

Early October 2013, Adobe announced that they fell victim to a cyberattack and their database was breached to the degree that 2.9 million customers are impacted in one way or another. From my point of view it is great that Adobe regrets the incident and apologizes for the inconvenience, but I believe that we as consumers should and must demand so much more than a simple “we are sorry”. In the event this breach is new to you, then I urge you to visit Troy Hunt’s new site ‘;–have i been pwned? Troy has done an exceptional job at bringing …
