6 of the best free Linux firewalls
You're walking down a dark alley, late at night, when suddenly someone jumps out at you and forces you to hand over your passport, your credit cards, and the keys to your car. This is a decent analogy of what using the internet is like.
Around every corner lurks danger, and given today's always-on connections, you may have the internet equivalent of burglars without even realising. For ultimate computer security, a firewall is similar to having a big, burly bodyguard walking down the street with you, keeping you safe. Most modern routers come with firewalls to help protect you, but if yours doesn't then a firewall distro should be able to help you, whether we're talking about a home or office network.
