9 Deploying NSX Micro-Segmentation Deployment Options: Distributed Segmentation Controlled Communication or Isolation between workloads on the same or different VLAN Distributed Firewall applied to each vnic East-West Filtering by NSX Distributed Firewall Existing physical firewall only handles North South communication Traffic discovery to determine required flows/rules. VMworld 2017 Advanced Partner Services can be inserted at each vnic Stateful DFW Policy Controlled Communication STOP STOP Stateful DFW Physical Router Content: Not for publication 9

10 Deploying NSX Micro-Segmentation Deployment Options: Distributed Segmentation and Network Overlays Logical Switches based on overlays to isolate/segment independent of the underlying physical network Distributed Logical Routers to optimize East-West Routing Edge Services Gateway can also be leveraged for N-S routing, N-S firewalling, load balancing, NAT, VPN Distributed Firewall providing Controlled Communication or Isolation between workloads on the same or different Logical Switch (overlay) VMworld 2017 Advanced Partner Services can be inserted at each vnic Stateful DFW Policy Controlled Communication Content: Not for publication STOP STOP Stateful DFW Distributed Logical Router 10

11 Deploying NSX Micro-Segmentation Deployment Steps: Deploying NSX Manager, VDS and Host Prep Pre-existing and Management and Compute clusters can be leveraged NSX Manager deployed in the Mgmt cluster and peered with the existing vcenter server VDS is required for all compute clusters Host preparation installs NSX VIB to all hosts in a cluster Non-disruptive operation VMworld 2017 Distributed Firewall is enabled on every VM with a default allowall policy Content: Not for publication Management Cluster VDS Compute Clusters VLAN 10 VLAN 20 VLAN 30 L3 L2 11

15 Micro-Segmentation Policy Creation Policy and Grouping Methodology Choose the policy and grouping methodology BEFORE beginning the process. Will provide a clear direction on how to tackle challenges along the way. APPLICATION INFRASTRUCTURE NETWORK 15

16 Micro-Segmentation Policy Creation Whitelisting and Blacklisting Whitelisting Definition A list of approved items. Anything not on this list is disallowed. More secure Advantages High degree of accuracy Minimizes false positives Easy to customize Can be established easily in different areas of the enterprise Disadvantages More time to manage Requires additional time to install Blacklisting Definition A list of unapproved items. Anything not on this list is allowed. Advantages Easy to manage Easy to install Updates quickly Disadvantages Exponential growth High rate of false positives, even possibly blocking necessary access Continual updates requires Hard to transition to whitelisting 16

17 Micro-Segmentation Policy Creation Firewall Rule Table and Service Composer Firewall Rule Table Analogous to typical Firewall rule table Provides overview of all rules in the system DFW Rules and Network Introspection Sections enable rule grouping UI and API Driven Service Composer One or more Security policies can be applied to Security Groups Policies define DFW rules and Service Chain. Abstraction enables efficient service deployment Independent policies are combined specific to each workload UI and API Driven 17

18 Micro-Segmentation Policy Creation Policy and Grouping Methodology Security Groups allow abstraction and grouping of workloads from the underlying virtual infrastructure End-Users and Cloud Admins are able to define application-centric security policies Security policies are applied to one or more security groups where workloads are members Security Tags are applied to Virtual Machines and can be used for dynamic Security Group membership Security Tag ST Virtual Machine VM Security Group SG Security Policy Members (VM, vnic) and Context (user identity, security posture) Guest Introspection, Distributed Firewall and Network Introspection Policies

19 Micro-Segmentation Policy Creation Dynamic Policy using Security Tags Example Requirements Apply differentiated policy based on OS, Environment, Automate policy application for new appliations being provisioned Upon vra Blueprint deployment All VMs part of an application are placed into a new Security Group Every VM is tagged with multiple tags identifying: Function, Zone, OS, Environment and Tenant App1 Apache App1 - WLS App1 - ORADB App1 Security Group DMZ_ PROD_ RHEL Apache TRUSTED_ PROD_ RHEL WLS RESTRICTED_ PROD_ RHEL ORADB

22 Micro-Segmentation Policy Creation Leveraging the existing FW policy Mostly relevant for Infrastructure and Environment Rules Analyze existing zones and rules and isolate North-South rules from East West rules. Determine flow patterns that are hair-pinned (East-west traffic). Also, helps you understand how to replace hair-pinned traffic with logical switches and routing using overlays via NSX. Correlate flow NSX patterns/logs with rules collected from perimeter firewalls.
