comment What is the proper setup procedure for SSL Tunnel certificates?
Just a hunch.... but Niagara use a Java framework if I'm not mistaken. Which means it's likely this subsystem that fails to work is using the Java Keystore, which will not contain the trusted root of the customers CA. Combining the cert chain is a workaround. You might try going down the path of importing the customer's root into the java keystore.... or.. it may end up being a waste of time. :) Sorry, I have no direct experience with Niagara.

Parking lot predators would vote for a combination lock. It would keep their victims distracted longer.

comment Options to protect an outbound initiated connection IP?
Sorry if I'm not following correctly as I'm a visual person, but it sounds like you might need to deploy a load balancer - or "Application Delivery Center" such as an A10 or F5 appliance that is hosting a VIP? As the crux of your issue relates to "we have no quick means to change that IP within all the customer configurations if we have an issue."

comment How to block detour programs that bypass firewalls?
This is where an explicit proxy can be beneficial. Some of the same pitfalls remain, but one could argue chances of bypassing are reduced. Many explicit proxies support decrypting SSL (MitM style) and categorizing URL's on the fly through real time analysis. Yes, it's true that some firewalls support SSL inspection but usually throughput suffers as a result. Have you subscribed to a category DB like Websense for filtering? If so you should consider blocking all remote/proxy categories. It's not a perfect "catch all" solution, but does get you a little farther down the road.

comment Is it dangerous to have the built-in Administrator account enabled?
Think of it this way... just because the admin account is "never" used doesn't mean that it "can't" be used. (if someone cracks or learns of the password) There are guard rails along highways with dangerous cliffs that have "never" been used. (thank goodness) but they are there none the less. Should they be removed because they are "never" used? Think of disabling the admin account as adding a guard rail alongside a dangerous cliff on the highway. It's a precautionary measure.

comment Force a specific SSL cipher
I just used the method in the answer and it worked great. Often times the ciphers reported by the scanning tool don't align with the cipher name that must be specified in OpenSSL. There is a handy list located at: openssl.org/docs/apps/ciphers.html

You might give this a watch: youtube.com/watch?v=NPqVVhxhqmY "The Little JPEG That Could (Hack Your Organization)" Even it's not susceptible you'll learn something really cool. :)

comment Implications of IP Address as Subject Alt Name in certificates
Heads up, if this is going to be used on an internal server - the use of IP's is going to be deprecated. symantec.com/connect/blogs/transition-non-fqdn-server-names

comment Fiddler show external requests but not initiated by any legitimate process
For the time being, you could add an entry in your hosts file to route www.google.pl to 0.0.0.0 until you can track this thing down.

comment Is there a way my organization can collect clients' sensitive documents without being liable for them?
You're already liable to be GLBA compliant for handling sensitive customer/financial data. (if you're in the US or doing business with a US company) Please review: ftc.gov/tips-advice/business-center/privacy-and-security/…

comment Penetration testing approach - Is there a better method?
@Atsby It depends on the scope. I've see some network pentesting companies who ran the equivalent of an nmap scan against our external network and collected a fat check. However, I've seen web application pen testing companies that were worth their fee and then some. These tests involved highly skilled and specialized pen testers utilizing human logic and intuition in combination with tools and were highly effective. I actually look forward to reading those reports because the things these people find are amazing. Long story short, you have to shop around till you find the right fit.

comment Are there any two way + two factor authentication systems in use?
@RoryAlsop I modified my out of band statement to be more accurate. However, if the premise is that it's not out of band because it can be compromised, then nothing can be truly out of band.

And always implement stored procedures when possible. Do not allow raw queries to the DB.

comment What is risk of having memcache in public interface?
The documentation I've read seems to indicate the application is susceptible to stored cross site scripting versus reflected - in which case social engineering isn't required. Also, please read the article over data ex-filtration. The person was able to extract cached data from mem cache. If any sensitive data was cached (userID's, passwords, connection strings, etc) it could have been compromised.
