E-commerce Server Security
I am new to linux and have been reading a lot of the articles and threads on this site for the last month and still feel a bit uncomftorable using linux without a GUI. Now I will most likely hire someone to help me with this to make sure it is done right in the first place but I am pretty good with computers and would like to learn as much as I can on my own. So for a bit your opinions please.
I am setting up an ecommerce site for my business and want to house the server in my office instead of using a hosting service. I want to keep costs down and I hear Linux/Unix is the best security match up for Apache.
What sort of security do I need for my ecommerce site?
Do I need a proxy, or can I use a normal router?
Will the Certificates be enough to protect the site? (eg. Verisign, hackersafe)
What is the most secure Linux Distro?
I was thinking of doing the site in PHP/MySQL or C Sharp. I want to make use of forums and blogs within the site as well so I am leaning more towards PHP but I heard it is also easier to hack.
Any feedback is appreciated.
