The document discusses the automation of security workflows using VMware's NSX Service Composer, emphasizing efficiency and consistency in handling security issues. It outlines a step-by-step approach to automate quarantine processes for infected systems and outlines the integration of compliance and vulnerability management workflows. Additionally, it highlights the benefits and capabilities of NSX in a software-defined data center, along with a case study on McKesson's use of the OneCloud platform.

production quarantine

Overview of Quarantine Use Case
 Quarantine Processes
• Quarantine by default
• Scan for compliance before putting in
production
• Remediate non-compliant systems
• Continuously monitor production
systems for compliance
• Quarantine non-compliant systems
• Optional: Require approval before any
workload is moved to quarantine
 Properties of Quarantine Zone
• Restrict Layer 3 network traffic to/from
zone. Block L3 traffic between infected
systems
• Assign different L2 network to
quarantine zone

Network Access Control As We Know It
 Requirements
• Authentication and
Management Services
• 802.1x enabled switch

• 802.1x compliant endpoint

 Challenges
• Cost-prohibitive (hardware)
• Difficult to manage (agents)
• Lacks agility required in the
software-defined data center
• Forces virtual network traffic

Automate Quarantine Workflow with NSX Service Composer
Prerequisites: Security groups
defined by tag membership and
relevant policies
1. Desktop group scanned
scanned for viruses
2. AV solution tags VMs to
indicate virus found
3. Infected VM automatically
gets added to quarantine
group, based on tag
4. VM is re-scanned and
remediated by AV solution.
5. Tag removed and VM moved
out of quarantine zone.

Concept – Apply Policies to Workloads
Security Groups
WHAT you want to
protect
Members (VM, vNIC…) and
Context (user identity, security
posture
HOW you want to
protect it
Services (Firewall, antivirus…)
and Profiles (labels representing
specific policies)
APPLY
Define security policies based on service profiles already defined (or
blessed) by the security team. Apply these policies to one or more
security groups where your workloads are members.

17. 17
NSX Service Composer – Canvas View
Nested Security Groups: A security group can contain other groups. These nested groups
can be configured to inherit security policies of the parent container.
e.g. “Financial Department” can contain “Financial Application”

18. 18
NSX Service Composer – Canvas View
Members: Apps and workloads that belong to this container.
e.g. “Apache-Web-VM”, “Exchange Server-VM”

19. 19
NSX Service Composer – Canvas View
Policies: Collection of service profiles - assigned to this container…to define HOW you want
to protect this container
e.g. “PCI Compliance” or “Quarantine Policy’

20. 20
NSX Service Composer – Canvas View
Profiles: When solutions are registered and deployed, these profiles point to actual security
policies that have been defined by the security management console (e.g. AV, network IPS).
Only exception is the firewall rules, which can be defined within Service Composer, directly. for
*deployed* solutions, are assigned to these policies.
Services supported today:
• Distributed Virtual Firewall  Anti-virus  File Integrity Monitoring
• Vulnerability Management  Network IPS  Data Security (DLP scan)

Automation Process Using NSX Service Composer
Use NSX security tags, either through NSX security solutions or APIs, to
define IF/THEN workflows across security services.
Step 1 - Define
security tags
based on
workflow
requirements
Security
Group =
Step 2 - Define
security group
based on tags
Step 3 - Set and
unset tags based on
security workflow
requirements.

23. 23
How to Automate a Workflow with NSX Service Composer
Step 1 – Define Tags
Determine which tags have been registered by the deployed security
solutions. Identify the tags you want to use for your workflow.
Example: I want to know when my antivirus solution finds any infected systems.

24. 24
How to Automate a Workflow with NSX Service Composer
Step 1 – Define Tags (alternate)
Use NSX tagging API to identify workloads of a certain type, by integrating
with a cloud management portal or by running a script.

25. 25
How to Automate a Workflow with NSX Service Composer
Step 2 – Define Security Group
Define group based on dynamic membership where tag has a certain value.
Example: My quarantine zone is defined by any system with a tag that has ‘VirusFound’ in it.

26. 26
How to Automate a Workflow with NSX Service Composer
Step 3 – Set and Unset Tags
A workload is added or removed from a group due to tag change.
Example: My quarantine zone will block network traffic but will also rescan workloads to see if
they are cleaned of viruses. If clean, the virus tag will be removed and the workload will be
removed from the quarantine zone..

Compliance Automation Use Case
 Compliance Processes
• Group systems that must be compliant
with a specific regulation and apply
necessary controls to the group
• Specify systems based on actual data
(through sensitive data discovery) or
desired compliance state
• Move systems in and out of compliance
zones based on above
• Optional: Require approval before any
workload is moved to compliance zone
 Properties of Compliance Zone
• Apply security policies as dictated by
the applicable regulation or standard
(e.g. antivirus, firewall, encryption, etc.)

Automate Compliance Workflow with NSX Service Composer
Prerequisites: Security groups
defined by tag membership and
relevant policies
1. Desktop group scanned
scanned for credit card data
2. Data security/DLP solution
tags VMs with sensitive data
3. VM with sensitive data
automatically gets added to
PCI DSS group, based on tag
4. VM is re-scanned for
continuous compliance
5. Tag is only removed if credit
card data no longer present.
VM would then be moved out
of PCI DSS zone.

Overview of Vulnerability Management Use Case
 Vulnerability Management
Processes
• Identify and routinely scan critical
systems for vulnerabilities
• Find critical vulnerabilities and move
them into monitor zone with IPS
• Prioritize remediation actions based on
most critical systems / risks
• Test patches, remediation in staging
zone before applying in production
• Rescan patched systems and move out
of monitor zone if risk is mitigated
 Properties of Monitor Zone
• Intrusion Prevention System (IPS)
policy monitors for compromised
systems and blocks risky traffic
