Secure Web Hosting
Security in web hosting for the most part is simple. The only way of acheiving anything even even remotely secure in a remote web hosting environment, (meaning you are not running your own server in-house), is to purchase a dedicated server. Any other web hosting package implicitly means your web site will be sharing a machine with other web sites.
Sharing a machine with other web sites is know as shared hosting. This means that if a hacker is good enough, rather than hack your site directly, they could hack the entire machine by hacking any unsecure account on that machine, and attack your account from the root level. With a dedicated machine at least it's just you against the hacker and you only need to worry about securing your account.
Don't get me wrong, web hosts are usuallyu ultra diligent about watching for intrusions on the servers they run, there are just too many vectors for your web site hosting company's support team to account for … namely the files and code that you and others place on the server. The web hosting company will be responsible for keeping all of the server software they provide you with up to date with the latest patches and security updates installed. But there is nothing they can do about insecure code that your write yourself, or your companies failure to update software that was self installed. These are the vectors that make any shared hosting setup a dangerous one.
