Should I have Internet security before getting internet service?norton internet security

for a first system, yes...

firewalls can be a bit tricky to configure, so watch for ones that have user-friendly interfaces (in other words, avoid BlackICE and a lot of the very technical firewalls, because it'll just be overwhelming)...anti-virus can be a good plan as well...as far as anti-spyware, i don't know how much i like them, because they often are just as annoying as spyware...but more than that, i have had ad-aware detect critical files as threats, and had to start from scratch because of it...

and NAT firewalls are also EXTREMELY crucial...these are found on most high-quality routers...also, for a first system, do _not_ run a wireless network, because the security on them is (to say the least) weak...but putting a router between yourself and your connection gives you the ability to more effectively repel intrusion and prevent sensitive data from going out...

currently, i'm running a server box, with no additional security measures, and have had no problems. but i've been working with these sorts of things for years, so i've learned what security measures are required on a system facing intrusion attempts, and how to most effectively protect sensitive data...
