Re: Use IP-Address Whitelisting as a second factor?

@EIAKPKP452: SAML is another provided option. The problem is, that not all connected affiliates have an ADFS in place. Local accounts with MFA is our fallback scenario.

 

@Early_Adopter: I'm sorry, but I signed an NDA with the vendor.

 

I now think the vendor uses the word "cloud" only for marketing purposes. In fact it is classical hosting and has nothing to do with the cloud principles (scalability, pay-as-you-go, ...). So it isn't surprising anymore that there is no valid MFA solution in place.

Re: Use IP-Address Whitelisting as a second factor?

As many people have already commented; whilst IP white-listing can be useful, from a security perspective, it is insufficient as an authentication factor.


This sounds like a scenario that I have experienced many times.

 

The vendor is attempting to proposition their product based upon current industry trends rather than legitimate technical capabilities.


It is very important to study RFP responses, and the technical validity of Sales pitches, to be sure you are getting a good product and working with a technically capable vendor.

 

You can also mitigate risk by seeking references from the vendor's other customers.

 

Technology research organisations can provide good independent insight.

Yes, a good point to make organizationally - "cloud" is a marketing term, not a standard. What is interesting to note, multi-factor authentication is not one of the requisite five attributes that (ISC)2 and Cloud Security Alliance designate (self-service, broad access, resource pooling, elasticity, pay as you go). A lot of this points toward that these services are still pretty cloudy (pun intended) in terms of what they offer and what they are. This can also greatly skew the metrics for measuring cost, benefit and risk.

I would term MFA a control to secure access as opposed to an attribute, I wouldn't expect it to be called out by CSA as such.

 

On those attributes, I think 'measured service' is preferred to 'pay-as-you-go' and addition of the ISO/IEC 17788 contribution of 'multi-tenancy'.

 

@deja On the NDA bit, why not refer the vendor to this thread? They can then have a look and a think and then perhaps consider how to enhance the security their service.
