I recently interviewed Peter Silva, Technical Marketing Manager with F5. We talked about an interesting problem facing CIOs today and one that CIOs in our roundtable group have talked to me about frequently. The problem is Dynamic Applications and Mobile Users. Why is this problem? There are three challenges that a CIO has to think about today that require support for Dynamic Applications and Mobile Users:
• Dynamic Applications (Delivered from Corporate IT services or Cloud Providers)
• Disaster Recovery Site Access
• Smart Device Access

Peter discusses his philosophy on F5 solutions sitting at the point of control on the network in order to make CONTEXT based decisions on where users go and what applications they can access.

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?
