Computer security cryptic crossword

In April, at the Infosec show in London, Sophos gave away a free newspaper including all kinds of interesting articles about computer security. It was a big hit (download it as a PDF, if you didn’t manage to pick up a copy).

On the back page there was a cryptic crossword, with answers of a decidedly computer security nature.

Surprisingly, no-one managed to complete the crossword! Now, we know it was very cryptic but surely there are some brainboxes out there who can finish it?

So, if you’re the first person plucked out of the hat to have sent us the complete solution we’ll not only give you a free Sophos fleece and a limited-edition Sophos-branded cool-bag, we’ll also tell the world how clever you are!

Just send your answers to (Sorry, the competition is now closed. Check out the solution to the puzzle).

Happy puzzling! And special thanks to John Hawes, Technical Consultant & Test Team Director at Virus Bulletin for putting the crossword together.
