RE: how to secure a commercial web site

Firstly let me apologise in advance if I have made this post to the wrong place. If so tell me what I did wrong and it 
wont happen again ;o)

Bilur,
Applying a SSL server does not make your site secure. All it does is allow the data from the client to the server 
encrypted. IE establishes a secure encrypted tunnel from you (IIS) to the client's browser. It does not however protect 
your server or infrastructure in any way. As already stated by Jeffrey, you will still need to do things like

(Microsoft Web Server- IIS)
IIS lockdown
URL scan
Remove unnecessary services
Lock down the registry to deny anonymous access
Install a good statefull firewall
Pen test the site. There are many tools for this. Nessus is a good free (Linux) example. 

If the clients are internal you can happily use a cert you generate yourself. If the clients looking at your website 
are anon people, it's best to get a Verisign or Thawte http://www.thawte.com/cert. It's all about perception. The cert 
is the same whether you buy one or make one (Provided you make the cert the same amount of encryption)

I hope this helps

Regards

Jason

Jeffrey, if i get what i pay for, i would do it..but this is the problem, they are not
secure enough, i can see this with my half knowledge..it means even if i pay for a certificate,
the reality will remain same : the security is depending on the user's computer's security. 
and even if every user has its own private key, it wont be a solution. am i making a 'terrible'
mistake in my thinking ??
..
alternative (and weak) thought : if i prepare my web page as https and if i put it into a secure 
server, and if i create my own certificate; will i have a 'secure' system ?
 
thank you for your patience,
regards,
bilur

James,

I think he was only asking/looking at ssl. We would have a very
long email if we were to talk about security. (Firewall,app level
security, tokens, secure os ....ect)

It is very common and cheap for people to want to just setup a quick
web server for business. (ssl) Secure? Not really, but what really is?
Expensive? Yes.. you get what you pay for.

There is a LOT more to security than having a certificate on your
server. It's necessary, but not sufficient.

Bilur,

You can buy your own cert server. (RSA Keon for example) 
At that point, you can create your own certs. (expire them when you
want..ect)

Also..

You then have two options.

1) Pay a fee and have your cert server 'trusted' via Verisign or other
CA's
or
2) Leave it 'private' and just provide your CA cert to the users so they
will
trust you. (if you don't it will still work. They will just see a
message about
trusting your site)

hi,
i am trying to secure -SSL certificated- a commercial web site without
using verisign, global 
sign, etc. it seems there is a monopoly an i want to be out of it. does
anyone know a better 
way to secure the web site or do i have to pay money, (even) for
security ?   
regards, bilur
