Reddit reviews Network Security For Dummies

With money;

• Offensive Security offers some good courses on netsec - Kali.org - they offer Kali Linux (a derivative of Debian - a distribution of Linux) too tbh.
  
  
• College/University is a pretty decent source for info more often than not.
  
  
• Also, start either with code or physical things. Windows has a lot of things to poke at actually. Usually good starter references (the “for dummies” books); https://www.amazon.com/Network-Security-Dummies-Chey-Cobb/dp/0764516795
  
  
  Without money;
  
  
• Start learning python 3. Will significantly help the more serious you get.
  
  
• Start with Wireshark and nmap - both are free applications that support most operating systems.
  
  
• Also, look at penetration testing resources as a good “go-to”. Reddit, Hak5, and DEFCON are good places to look for information. Hak5 & Reddit first though, DEFCON the more you get into things. My Reddit reference:

I definitely recommend books as a means of delving deeper into the subject of Network security. There is a For Dummies book selling on Amazon as well as several other books about the subject. Along with reading up on Network Security, I'd also recommend that you read up on hacking to better understand the threats to Networks.

Also, internationally there are hundreds of information security conventions, a quick google search should bring up a few results on upcoming events in your area. Some of them are about new technologies released and are typically aimed at companies wanting to upgrade their security, however there are seminars and panels at these events which are interesting.
