Greetings and Salutations.
Welcome to EVE. I suggest you start by familiarising yourself with what are referred to as the Eight Golden Rules. Specifically rule two: you explicitly consent to PvP in all areas of space by clicking on the Undock button.
EvE is not WoW. There is no “safe” space. You can, and probably will, be attacked in high security space. CONCORD is retribution, not preventing.
