Learn NSX Day 14 : Monitoring

Activity Monitor

activity-monitor

To monitor add VMs in to a activity monitoring security group (service composer)

Enable data collection
Then you can validate security policies are applied

Monitor Traffic

vDS allows port mirroring to be configured
Remote mirroring is an option to configure. (duplicate traffic to another port)

Flow Monitoring

flow-monitor

Includes the ability to detect rouge services

Learn NSX Day 13 : Distributed Router and Distributed Logical Firewall

vDS (Distributed Switch)
An interface on a distributed switch can connect to the rest of the network

distributed-switch

Advanced Settings

distributed-switch-settings

To implement:

Enable OSPF
OSPF
Config uplink
Add subnet to new interface
Assign VLAN number to distributed port group for VLAN IF

Limits

There can be up to x1000 logical interfaces to one distributed router

Distributed Logical Firewall
Diagram to try and display my understanding of how the firewall rules apply based on security groups

Rules only apply to the ESXi hosts which have the source or destination VM traffic

These are notes made during my study of VMware NSX for vSphere. Apologies if any of the detail is incorrect. Hopefully posts under “Learn NSX” help others to start learning about VMware NSX for vSphere.

Learn NSX Day 12 : Spoof Guard

Spoof Guard

A useful feature, help prevent rouge systems connecting in to your network by pretending to be another server. An approved list of authorized servers is generated on IP, MAC. This is a separate feature from firewalls. My understanding it would increase security alongside firewall rules. See VMwares description for further information

spoof-guard

Operation Modes

Auto trust IP on their first use
Manually inspect and approve before use
