Level Up 1: Can check firewall settings with iptables

gistfile1.txt

1. On your development machine, see what rules are currently loaded in the firewall. If it's not running, shame on you, start it first.

To view the current rules: sudo iptables -L

2. Explain why a whitelist approach is better than a blacklist approach for firewalls?

A whitelist is better because a blacklist won't block a threat that is unknown before the attack. With the whitelist approach, it would be blocked by default.
