Is this a b'log, a wiki or a knowledge base? Good news everyone...

… it’s all of it.

It's a me, Marius



I am an information security professional, and practice “Infosec” since over 10 years. Lots of things fascinate me, and the field has a lot of bright people. I enjoy working with you.

When I am not online I enjoy :candle: Yoga, :japanese_goblin: Martial Arts or probably some good food and :de: beer.
