I have nothing to say new just 2nd others that start from the beginning and get all knowledge. Read as much as you can about cyber security, bookmarks some good sites that write news, blogs and have specialist or expert interviews from cyber security world. Forbes, Wired, Onlineprivacytips, WSJ, CNBC, Cnet etc should be in your bookmark list.
Join some good cyber security group on social networks and participate in discussions, ask queries that you have in mind and see what experts suggest you as per their experience.
