I am planning to get my website development outsourced to a third party developer. Need your help in deciding on how/ what technology to be used to make it very secure. Since I am not a techie I need the website developed in a way, so that it is easy for me to maintain it and modify content easily if required.

The main purpose of 开发者_C百科the website is to provide company information about services offered and then also to exchange documents and other file using FTP server. Will be sending out surevey and newletters sometime

As I already said on another answer, security is not a product, it's a process.

There isn't a 'secure' software or language. What makes your website/application secure is how it is developed and how the website is maintained.

There is no ready-made solution that, one time or another, won't be hacked.

If the people you are outsourcing to don't understand this, outsource to someone else.

Making your web server "hardened" against attack is best left to the expert sys-admins at Server Fault. However regardless of what technology you use, there is one HUGE thing an end user can do to protect her/his online assets:

USE STRONG PASSWORDS

You can make a site secure using any technology/language/framework.

It's the code quality that makes a site insecure, not the technology/language/framework.

There is no single "correct" language to use -- it's possible to write an insecure website in any language.

The key is hiring staff that have the skill and experience in developing secure web solutions, and also making sure that the system is tested often by external specialists
