This collection of cryptic crossword puzzles is themed around the subject of cyber-security. Each one has been published previously in the Institute of Information Security Professionals' quarterly journal entitled "Pulse". You will need a modicum of knowledge of the subject area of information security - however the majority of clues are of a general nature. I have followed the format and style of "The Times" cryptic crossword and the difficulty level is generally towards the easier end of the spectrum. The clues are of the type that I personally find entertaining to solve, but the selection of clue types is mixed and generally balanced according to the aforementioned style. I hope you enjoy solving these and would welcome any feedback that you may have. - D.Rex
