Hi - I run my home network including an Exchange Server that handles our email and outlook mobile access, behind an Astaro firewall. The only incoming ports are 25 and 443 that go to the Small Business Server.

Do I need to enable Astaro's intrusion prevention system?
Is it worth the hassle / overhead?
Will it really make much difference given I rely on Window IIS authentication using strong passwords?
I have a fully up to date and patched system.
I don't have firewall restrictions on outbound access ... we have 'clean' systems here.
Would IPD/IPS help in any way if I did get malware inside my network?
Any thoughts appreciated!

You probably dont need to in order for the firewall to function, but I would.

Is it worth the hassle / overhead?
Intrusion Prevention is usually worth the hassle. There shouldn't be much overhead after the initial setup and configuration. Yes. In the event of your systems being compromised

Will it really make much difference given I rely on Window IIS authentication using strong passwords?
Strong authentication using passwords is only a single piece of a highly secure network.

I have a fully up to date and patched system.
Many times, vulerabilities are exploited BEFORE official patches are released. It is not wise to soley rely on the software vendor for patches.

I don't have firewall restrictions on outbound access ... we have 'clean' systems here.
It is not safe to assume your systems are clean. While they may well be clean at this time, there are many events that could occur that would change that fact.


Would IPD/IPS help in any way if I did get malware inside my network?
Yes. Intrusion protection can monitor outbound accesses and also monitor packets going out of your network. Many times you can save yourself a lot of hassle by just looking up suspicious port number traffic.
