Play capture the flag games to get hang of vulns but I hope that military has firewalls written in Ada/Rust and formally verified or fuzzed hard. In comercial setting defence works by updating DB of viruses and network monitoring (basically watches all open ports and inspects tcp/ip packets). Still def is hard as weakest chain loses and this means phishing, sms, email. If I were Russian I would have agents working in FB/Twitter and bomb/stalk people based on that. IMO best software engineers can do to maintain power balance are temper proof communication tools that are easy to use. Best if work also without internet - so called mesh-networking.
