Folks,
Many of us tend to be a little complacent regarding firewall security when we are working behind a router so just want to ask opinions.
If I directly connect a Linux Ubuntu computer to the internet is the following iptables rules sufficient for basic use?
sudo iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
sudo iptables -I INPUT 1 -i lo -j ACCEPT
sudo iptables -A INPUT -j DROP
No servers being run on this machine and ssh access not required.
