simplicity improves security?

[Saqib Ali <docbook.xml () gmail com>]

Hello All,

I am looking for a quote to end an presentation, that talks about how
simplicity in an application can improve the security, whereas a more
a complex application will be more prone to security related issues.

Any quotes from any security gurus?
