DMZ Exposure

9

• There is *always* a risk for an asset placed on a DMZ network

– It’s allowing incoming connections from a lower trust zone (frequently the internet)

– Even if a webserver is completely patched and locked-down for allowed ports, it’s still vulnerable to attack from other servers on the same L2 network

• Backend Connections (3-tier apps)

– Many services require connections back to other DBs or servers; allowed connections into higher-trust networks must be closely monitored and restricted

Traditional DMZ Design Principles

Assumption is that any infrastructure component exposed to the external network is inherently “vulnerable” and is always at risk.

There is a need for isolation at the hardware, network and software layers

1. Purely Physical DMZ 2. Partially Collapsed DMZ with Physical

Separation of Trust Zones

3. Partially Collapsed DMZ with VLAN

Separation of Trust Zones



bution

Many Ways to Screw Up A DMZ Network

14

• Network Segmentation

– Too large a blast area

– Servers with differing criticality

– Failure to separate from internal network

• Too many connections allowed to higher-trust networks

• DMZ servers using same resources as Internal networks

– Admin passwords, DNS, AD

• Success of DMZ highly dependent on overall architecture/implementation

• Few generally accepted, industry-wide guidelines

• No one product makes a secure DMZ – require a solution along with people/process



bution

DMZ in Trouble

15

The need for secure DMZs as a part of security architecture increases

Server Breaches

• 63% of confirmed data breaches used weak/default/stolen credentials

• Phishing!

• Let anyone on the Internet access a server?

• That should be on a DMZ, unless higher-trust

(device, 2FA, RA VPN, S2S VPN)

• 20,000 incidents of websites used to host malware,

participate in DDOS, or altered to server up a phishing site

• 2,800 website defacements

• 95% confirmed web app breaches tied to criminals

• Mobile Applications

• End - User Computing

• Cloud



bution

A Reality Check

• 53% of breaches were discovered by external parties

(partner, customer, law enforcement, etc.) who then

notified the victim

✓ 320 Days = Time until 3rd party detection

• 47% detected internally

✓ 56 Days = Time until Internal Detection

Anatomy of an Attack - Target



bution

Target: Even Big Organizations Get It Wrong

…when a work order for an external vendor is created, the payment is collected through the Ariba system: Vendors log into Ariba, complete the necessary steps to close out the work order and they are later paid. But how would the attackers have moved from Target’s external billing system into an internal portion of the network occupied by point-of-sale devices? The former Target network expert has a theory:

“I know that the Ariba system has a back end that Target administrators use to maintain the system and

provide vendors with login credentials, [and] I would have to speculate that once a vendor logs into the portal they have active access to the server that runs the application,” the source said. “Most, if not almost all, internal applications at Target used Active Directory (AD) credentials and I’m sure the Ariba system was no exception. I wouldn’t say the vendor had AD credentials but that the internal administrators would use their AD

login to access the system from inside. This would mean the sever had access to the rest of the corporate network in some form or another.”

ESG / DLR Design Considerations

• Can be one routing topology for all DMZ functions or multiple for DMZ functions

• Routing logic should be separated for DMZ and Core N/W DC functions (min two DLRs ) for a

deployment.

• Routing between DLRs must pass through an ESG. You can use 1 or more ESGs for this

function, but with the ESG Firewall in deployment there is not support for ECMP.

• Same rules apply for Universal Objects, such as UDLR, as well.

– Version 6.3 supports multiple universal sections allowing a separation of Internal and DMZ Universal rules.

Testing and Exploits Used

As with the 2016 benchmark, we used a Kali Linux based testing VM, loaded with suite of penetration testing tools and Metasploit Framework

Use of Kali Linux to simulate a fully compromised, previously exploited machine at it most extreme level of lethality. Machine positioned into design pattern networks as an optimal attacker. This machine is denoted by this VM symbol in our Design Patterns:

• db_nmap reconnaissance tool – scans from the Kali VM east-west (L2) target VMs and across application tiers the north-south (L3) targets

• WannaCry exploit – based on EternalBlue MS17-010 (CVE-2017-0143) as cryptovirus / ransomware candidate

• Java AtomicReferenceArray – type violation vulnerability (CVE-2012-0507) as an application-based and browser/Java exploit

55



bution

TEST METHODOLOGY – Using MetasploitNSX DMZ Anywhere “Micro-audit”

56

Simulate an actual automated or human-initiated attack, using tools and exploits that are real.

Follow the Kill-Chain model, performing the Reconnaissanceand Exploitation steps.

The CONTROL Test Pattern confirms exploit success.

Test Pattern “1,2 and 3” are with NSX DMZ Anywhere security principals engaged.

VMware vSphere and NSX SDDC “Test-bed” with:

• Kali Linux “Exploited” machine launching attacks via Metasploit, db_nmap, hping3, etc.

• OpenEMR and OpenMRS workloads

• Windows 2008 R2 and 2012 R2 Enterprise for OpenEMR

• Debian 4 Linux w/ Apache/MySQL for OpenMRS



bution

Test Results – Recon and the Design Patterns 1 - 3

• db_nmap used to probe and test

• Tested using a “Control” and “Test Protection” NSX DMZ Anywhere event

• Control – Open, NSX Rules turned “down” using allow policy or policy removed. Confirm recon

success

• Test Protection – NSX Rules enabled to Block and Reject

Test Results – Sample of Attacks

Test Results – Methods Used to Benchmark Service Insertion Partner Firewalls with NSX DMZ Anywhere

• Identical testing model for Check Point and Palo Alto Networks next generation firewalls. Both

firewall suites are provided as SVM utilizing NSX NetX extensibility framework

• Tested a “Control” and “Test Protection” scenario with Patterns 2 and 3 as in previous tests

• db_nmap used to recon, and recon is ALWAYS successful with Patterns 2/3

• Service insertion for L7 by Check Point and Palo Alto Networks where traffic steering is managed

by the NSX network flow

• Control – NSX service insertion policy not applied. Confirmed exploit was successful without

service insertion and inspection by partner solution

• Test Protection – NSX service insertion policy applied to insert next generation application

firewall into the attack flow

Use Case: De-scoping for Regulatory Compliance

Regulated data at rest and in motion must avoid being on the same network with non-

regulated data VMs. Moving IPs or to a DMZ is difficult, costly and often impossible.

In this PCI DSS example, machines in

RED are in-scope and store, process or

transmit cardholder data (CHD).

DMZ Anywhere can apply the DFW rules

to these VMs in place, and generate the

zero-trust rules to protect the CHD.

NSX DMZ Anywhere Benchmark Conclusions

Coalfire’s objective was to determine if VMware NSX DMZ Anywhere can prevent E-W/N-S threats by

performing a “micro audit” using representative malware and kill-chain methods, and scientifically measure the

results. Testing focused on DMZ Anywhere in a stand-alone configuration and when used in a service insertion

scenario with Palo Alto Networks and Check Point next-generation firewalls.

Coalfire’s findings were:

• NSX DMZ Anywhere provided significant and real distributed firewall (DFW) protections against E-W

threats and in inter-segment DMZ transfers between tiers of our test Windows and Linux three-tier

workloads

• Policy-based controls, nested service group constructs, tight integration with VMware objects/meta-data,

the completeness/utility of tools (ARM / Endpoint Monitoring, etc.) of NSX DMZ Anywhere satisfied NIST

SP 800-125B Requirements

• Specific testing of Application Rule Manager/ Endpoint Monitoring confirmed an easy deployment path to

zero trust implementation can be realized with NSX for DMZs

• Third-party service insertion was verified with the Palo Alto Networks and Check Point next-generation

firewalls to support L4-L7 threat mitigation in L2 and L3 DMZ designs
