perfect security architecture (network)

[C0BR4 <cobradead () gmail com>]

Hey guys,

Have couple of questions need answers plz...........

There are three attacks that jeopardize Information security. 

                                ------------------------------
- secure Network      -
------------------------------
- secure Host           -
------------------------------
- secure Application  -
-------------------------------

How can we optimize security? Stopping attacks at network or building
secure applications..

How should we deal with these attacks? People talk about Firewall, IDS/IPS etc..

What's best?

If asked to give a perfect security architecture (network) what would
you suggest?  Given
a Firewall, Router, IDS, IPS and Anti-virus .

thank you
