The Best IDP/IDS/IPS Intrusion Prevention System: Do you Really Need One?

In my normal line of work, I always get questions regarding certain technologies I use to secure my network beyond the usual firewalls

One of them is the IDS (Intrusion Detection System), IDP (Intrusion Detection and Prevention) and IPS (Intrusion Prevention System)...

It's just a play on words thou IDS is merely detection which is inutile since the damage may have been done already.

As for me I prefer the IDP/IPS particularly the inline type i.e. placed before the server/network to be protected rather than one that's just passively listening on a mirrored port.

But I was asked why it' took me so long to ever think of buying and justifying one. It's just that it's hard to justify expensive security systems if you're going to face traditional thinking superiors looking for security ROI.

I'm more into securing the hosts: the OS and apllication more than expensive security equipment...

adding an IPS is just another layer of security for me.

If you're looking for the best there is, I can;t make recommendations but it's always Tipping Point, Forescout, IBM's ISS et al or probably the free Snort :P

Statcounter Down, Unavailable, Unreachable or Bankrupt?

For a few days now I can't access Statcounter.com, my main website analytics script on my blogs. I simply can't access their website to get a snapshot of my daily visitors

What happened to Statcounter.com? there's no latest news and updates I can find there except in 2004 and also when thei datacenter went down due to a bomb explosion. What happened this time, I don't know. Chapter 11? bankrupt due to the economic crisis?

i may have to swtich to another web analytics to make up for the loss, Google Analytics won't cut it alone though I love theier integration with Adsense.

Firefox Crashes in Windows Vista Problem, Is there a Solution?

My Firefox 3 always crash randomly while browsing on Windows Vista Home Premium. Again, forums have no clear and definite cause and solution, not even on mozilla.com so i'm investigating this myself.

one of my observations is that it crashes everytime I click a link to open an email in gmail. Will have to check if it's the culprit or probably a Google Seach link will crash or have it shut down.

I'm also thinking of disabling all of my add-ons and plugins and enabling them one by one to eliminate my hunch that it's one of the Firefox extensions that's causing the crash. At first I suspected it's due to an update in one extension that's causing the crash (where in Windows XP, the browser just slows down or hangs, but not crash without any errors for forensics purpose)

McAffee Siteadvisor
NoScript
Adblock Plus
IETab
SearchStatus
CustomizeGoogle
Firebug
Add N Edit Cookies
Microsoft.Net Framework Assistant

As of now, I'm using Internet explorer 8 for my Gmail and blogger account. will test Firefox 3 with google if it still crashes, I might disable CustomizeGoogle first.

I will also try to simulate using Windows Saafe Mode

This will be updated until I find the solution myself or the problem solved somewhere on the Internet

UPDATE:
Windows Vista Firefox crash really caused by Gmail, I stopped using Gmail on Firefox and that solved the problem. I will simulate uninstalling one of the add-ons later to see if it still crashes. Maybe I start with Customize Google

SOLUTION: This problem was fixed recently with the release of Firefox 3.0.11. SO it's really a Firefox problem with Vista and not of any plugin that's why I wasn't able to fix it.
