Re: System i web accessibiltiy setup

["Shalom Carmel" <shalom@xxxxxxxxxx>]

Kevin,

Basically, your "microsoft" people are correct. Although a System i
can be as secure as any other system, from the security paranoia point
of view it is best to let a "bastion" server handle all of the direct
connection to the internet. This is just in case a direct attack on
the web server infrastructure succeeds.
Fortunately, you can have the best of all worlds by placing a simple
apache reverse proxy in the DMZ, and tunneling all of the http traffic
through the reverse proxy to your system i. This way, the system i
serves the web site, but an expendable box is connected to the web.

However, no infrastructure setup will protect you from application errors.
Take a look at the OWASP top ten web application security flaws. 9 out
of 10 are relevant to the system i.

http://www.owasp.org

OWASP is the best single source of web application vulnerabilities,
both generic and language specific. If your web site will contain Java
or PHP, then you will find at OWASP a lot of good advice.

In my book, at www.venera.com, I have some examples of iseries web
application errors and flaws, like unvalidated input, undeclared
global variables, and sql injection.

Shalom Carmel
