Medium/small business wanting a firewall - Can I do it?
I'm a student and have a part-time work in a firm that delivers retail store solutioins. Our systems connect and use our own servers extensively - we have great networking demands and complex networks (that need to be available at all times).
It has recently become clear that we are in need of a new firewall. The old one is a Trustix linux distribution from a provider and they want to sell us a new dedicated box (for a lot of money). My boss, my colleagues and I are wondering if this is something that me and my buddy could do ourselves.
I'd love to hear your thoughts!
I have a good understanding of the TCP/IP networks and I feel I would be able to set up a firewall with some kind of open source firewall-distribution. But how secure are these? And there is an uptime-demand that gives me little flexibility. How long would it take to understandthe iptables syntax? I imagine this is what has to be used?
If i get this job, there's a lot of responsibility on me and my buddy. This worries me a little, but at the same time I think firewalls aren't too complex, and once configured correctly and working, what can go wrong?
Please give me some input, thank you!
