IIS in Cloud

Just to elaborate further what I'm looking for:

a) in the case of Struts for Apache, we'll need to address Struts vulnerabilities from time to
     time on top of Apache's vulnerabilities.  So does this IIS module also add on this extra
     potential vulnerability that we have to address from time to time?

b) does Windows 2008 R2 and IIS patches that are released by MS affect this module?
     Any special handling needed?

c) is there any VA scanner like Nessus (or Outpos  in our case) that could scan for this
    module's vulnerability?

d) does any IIS & Windows 2008 R2 hardening affect this module in any way?

In the case of plug-ins, I've seen Firefox introducing vulnerabilities.

This module appears to be F5 (loadbalancer) related: we do use F5 but I'm uncertain how does it interact
or what is its impact on F5.


Some of the Firefox & IIS "plugins" related vulnerabilities that our IPS has reported:

Is this module (given by the CDN provider) some sort of plugin?

Java/JRE plugins is another concern that we have to patch & apply IPS signatures from time to time.

In the case of Java/Firefox & some common plugins, we can still get patches from Oracle/Firefox but
I'm concerned that if this module is not well-supported & one day has a vulnerability, there's no
vendor to produce patch for it;  if it's uncommon, our IPS products may not produce signatures for it.

If it's not a plugin nor some add-ons that will give rise to security risk, then do let me know how it's
being assessed as such so that we'll proceed to have the tenant install it

I personally prefer to use software developed by big players like MS n Oracle as they are seen as frequently developing patches for the likes of IIS, .Net, Java/Jre.


Curious if the IPS filter I listed earlier has any relation to this Isapi module:

Sorry the formatting was out in my last post: the first 3 and a half lines was supposed to be at the bottom

I recall there is a way to configure in F5 LB such tt the clients source IP is logged in IIS logs : correct me if I m wrong.   If so we wont need this Isapi filter

Excellent
