Hiking

Continuing my autumn trips, I went hiking over the last weekend of September which happened to be a long one in Czechia. This time I went to the Krkonose Mountains which are the highest and most visited Czech mountains. I booked a great hotel.

All in all it was a great and relaxing experience the highlight of which was a 20 kilometer hike at ~ 1.300m height.

Sailing as an infosec lesson

Sailing as an infosec lesson

Last Thursday I took my CRISC exams and - the restless person I am - I had already arranged to take sailing classes over the weekend. I always wanted to take sailing classes, and I had gone sailing once several years ago when I was still living in Greece. My idea was that when I grow old I will buy a small sailing boat and sail around my beloved Crete.

When multi-factor will not save you

There is a lot of discussion lately about multi-factor authentication and how this will upgrade everyone's security. Indeed, it is an improvement and it was about time we start becoming more conscious about the security issues related to authentication.

I think it's more than 20 years since I last planted tomatoes. It must have been in my second year when I was studying Agriculture in TEI of Heraclion. Since then many things have happened, among which the fact that I now live in a completely different country.

The idea to grow tomatoes in Prague was intriguing, so I got some Greek tomato seeds from my father, a small glass structure for the flat to pretend it's a greenhouse, and put them there. Some (several) months later, I'm happily eating my huge tomatoes. No pesticides of course, and only a little bit of organic calcium to deal with calcium deficiency resulting to blossom end rot.

Preparing for CRISC

Preparing for CRISC

I enjoy learning new things. Everyone who knows me can attest to that. I also have fun taking tests and quizzes. So it's not a surprise that I always try to find ways to combine these two activities.

I have pursued one academic degree per decade (approximately). I got my BSc in 1993, my MSc in 2000 and my MBA in 2007. Maybe it's time for another academic degree, but it's getting more and more difficult due to time constraints and, of course, the fact that I'm getting old. Not to mention the cost.

GISD 2018 - Spring Edition

On Thursday, the 31st of May I was invited to participate in a panel discussing artificial intelligence and machine learning. The event, Geneva Information Security Day 2018, was organized by High Tech Bridge. If you don't already know High Tech Bridge, it's a Geneva - based security company which constantly gets awards and recognition for their AI technology. Just this week, High-Tech Bridge's ImmuniWeb was named the Winner in "Best usage of Machine Learning / AI" category at SC Awards Europe 2018.
