Thanks to our sponsor RedZone for providing the reference document of technical questions to ask your Virtual Desktop VDI vendors.

  • How do they handle expanding hard drive drifts?
  • How do they handle OS Operating system patch management and size issues?
  • What SANs do they support native interaction with?
  • Application virtualization/streaming
  • Session control and management
  • How is offline mode handled?
  • What virtual infrastructure native support do they have?

As the old fashioned firewall concept has morphed into one that is a multi faceted security perimeter, I have developed a series of questions that can uncover the correct answers to you as you continue to refine and define what the security edge should look like for you. Use the reference architecture for this post that I have built that you can find HERE

From an ease of digestion perspective, I am going to release this in two parts since there are 22 questions. As always, if you have questions email me at billm@cioes.org or post a question to my blog below. Thanks, Bill

Reference Architecture Intelligent Perimeters: Edge Sites, Private WAN, Internet, Public WAN, Cloud Access Control.

Sample Technologies covered are: Firewalls, UTM Firewalls, App Proxy, IDP/IDS, DLP Systems, SPAM Filters, Load Balancers, Content Filters

1. Are DMZs deployed for network segmentation for interfacing with Internet customers, and partners?

2. Confidence level of DMZ on a scale of 1-10. (10 is very confident)

3. Has a detailed cable trace been done to validate the DMZ?

4. Preferred Firewall manufacturer?
•Do the firewall rules explicitly deny traffic to and from the DMZ?
•Is the version level current with the offering of the manufacturer?

5. Are services like Ecommerce sites and other systems hosted in the DMZ?
Are there any concerns about architecture?

6. On a scale of 1-10 does your DMZ match the security policy of the organization?

7. Where does standard VPN access terminate? Have they been reviewed?
•DMZ
•Firewall
•LAN

8. Firewall – Is it a UTM (Unified Threat Mgmt device) providing IPS, Gateway anti-virus, anti-spyware?
If no,
•What is the approach for IPS?
•What is being used for Anti-virus/
•What is the approach used for anti-spyware?

9. Do you have redundancy on the following?
•ISP – inbound
•ISP – outbound
•Firewalls
•Load Balancers
•Content Filters
•VPNs
•SSL VPNs

10. Is there a dedicated device for web content filtering?
•For What? Check all that apply? Web, Email, DLP
•Is it AD Aware?

11. How is Anti spam and Phishing handled?

What happens to your employees, 1099 contractors, partners, work at home employees, travelling users, remote sites, in which you don’t back haul internet users through corporate? What happens if these users leave the company and want to access applications that you have in the Cloud? How do you deprovision them from all the different Cloud touchpoints that exist? I realize you have a solution for some of them, but what about ALL of them? In this video, I review a few options that you have.

The CIO is in charge of SIP – Security Identity and Privacy Strategy….right? Well, someone is. Someone is taking on the responsibility. CIOs may not get into the nitty gritty technical minutia or product selection, but my point is that Cloud Access Control and security is about architecture and design. And for the most part, the points that I am making ,most serious SSL VPN vendors support, so we don’t need to go down the product path here.

Security Architecture and design matter first, no matter how close you may be to the board level meetings that we all aspire to.

A directory based approach is critical and I will make this point here and in future TV spots. And yes, I would agree that federation is the best approach overall, but I would prefer to discuss what is real and practical today for 100 % of the CIOs and this is why I want to review SSLVPNs and the power this gives you for access control into Cloud Services. I would like to emphasize these are YOUR Cloud services with capital letters. How can you manage risk that the cloud represents with simple access control?

I want you to be in a position of control. We are giving up enough control via Social Media infiltration into the enterprise. We have our hands full, but let’s take one concern off the plate. When you push apps into the cloud you now need to know who and what people have access to various services outside of your directory.
