This chapter introduces the VMware®vShield™ components you install.

The chapter includes the following topics:

“vShield Components at a Glance” on page 7

“Deployment Scenarios” on page 10

vShield Components at a Glance

VMware vShield is a suite of security virtual appliances built for VMware vCenter™ Server integration.

vShield is a critical security component for protecting virtualized datacenters from attacks and misuse helping

you achieve your compliance-mandated goals.

vShield includes virtual appliances and services essential for protecting virtual machines. vShield can be

configured through a web-based user interface, a vSphere Client plug-in, a command line interface (CLI), and

REST API.

vCenter Server includes vShield Manager and vShield Zones. The following vShield packages each require a

license:

vShield Edge with Port Group Isolation

vShield App

vShield Endpoint

One vShield Manager manages multiple vShield Zones, vShield Edge, vShield App, and vShield Endpoint

instances.

vShield Manager

The vShield Manager is the centralized network management component of vShield, and is installed as a

virtual appliance on any ESX™ host in your vCenter Server environment. A vShield Manager can run on a

different ESX host from your vShield agents.

Using the vShield Manager user interface or vSphere Client plug-in, administrators install, configure, and

maintain vShield components. The vShield Manager user interface leverages the VMware Infrastructure SDK

to display a copy of the vSphere Client inventory panel, and includes the Hosts & Clusters and Networks

views.

vShield Zones

vShield Zones provides firewall protection for traffic between virtual machines. For each Zones Firewall rule,

you can specify the source IP, destination IP, source port, destination port, and service.

vShield Edge

vShield Edge provides network edge security and gateway services to isolate the virtual machines in a port

group, vDS port group, or Cisco®Nexus 1000V. The vShield Edge connects isolated, stub networks to shared

(uplink) networks by providing common gateway services such as DHCP, VPN, NAT, and Load Balancing.

Common deployments of vShield Edge include in the DMZ, VPN Extranets, and multi-tenant Cloud

environments where the vShield Edge provides perimeter security for Virtual Datacenters (VDCs).

Standard vShield Edge Services (Including Cloud Director)

Firewall: Supported rules include IP 5-tuple configuration with IP and port ranges for stateful inspection

for TCP, UDP, and ICMP.

Network Address Translation: Separate controls for Source and Destination IP addresses, as well as TCP

and UDP port translation.

Dynamic Host Configuration Protocol (DHCP): Configuration of IP pools, gateways, DNS servers, and

search domains.

Advanced vShield Edge Services

Site-to-Site Virtual Private Network (VPN): Uses standardized IPsec protocol settings to interoperate with

all major firewall vendors.

Load Balancing: Simple and dynamically configurable virtual IP addresses and server groups.

vShield Edge supports syslog export for all services to remote servers.

Chapter 1 Introduction to vShield

vShield App

vShield App is an interior, vNIC-level firewall that allows you to create access control policies regardless of

network topology. A vShield App monitors all traffic in and out of an ESX host, including between virtual

machines in the same port group. vShield App includes traffic analysis and container-based policy creation.

vShield App installs as a hypervisor module and firewall service virtual appliance. vShield App integrates

with ESX hosts through VMsafe APIs and works with VMware vSphere platform features such as DRS,

vMotion, DPM, and maintenance mode.

vShield App provides firewalling between virtual machines by placing a firewall filter on every virtual

network adapter. The firewall filter operates transparently and does not require network changes or

modification of IP addresses to create security zones. You can write access rules by using vCenter containers,

like datacenters, cluster, resource pools and vApps, or network objects, like Port Groups and VLANs, to

reduce the number of firewall rules and make the rules easier to track.

You should install vShield App instances on all ESX hosts within a cluster so that VMware vMotion™

operations work and virtual machines remain protected as they migrate between ESX hosts. By default, a

vShield App virtual appliance cannot be moved by using vMotion.

The Flow Monitoring feature displays allowed and blocked network flows at the application protocol level.

You can use this information to audit network traffic and troubleshoot operational.

vShield Endpoint

vShield Endpoint delivers an introspection-based antivirus solution. vShield Endpoint uses the hypervisor to

scan guest virtual machines from the outside without a bulky agent. vShield Endpoint is efficient in avoiding

resource bottlenecks while optimizing memory use.

vShield Endpoint installs as a hypervisor module and security virtual appliance from a third-party antivirus

vendor (VMware partners) on an ESX host.

Deployment Scenarios

Using vShield, you can build secure zones for a variety of virtual machine deployments. You can isolate virtual

machines based on specific applications, network segmentation, or custom compliance factors. Once you

determine your zoning policies, you can deploy vShield to enforce access rules to each of these zones.

Protecting the DMZ

The DMZ is a mixed trust zone. Clients enter from the Internet for Web and email services, while services

within the DMZ might require access to services inside the internal network. You can place DMZ virtual

machines in a port group and secure that port group with a vShield Edge. vShield Edge provides access

services such as firewall, NAT, and VPN, as well as load balancing to secure DMZ services.

A common example of a DMZ service requiring an internal service is Microsoft Exchange. Microsoft Outlook

Web Access (OWA) commonly resides in the DMZ cluster, while the Microsoft Exchange back end is in the

internal cluster. On the internal cluster, you can create firewall rules to allow only Exchanged-related requests

from the DMZ, identifying specific source-to-destination parameters. From the DMZ cluster, you can create

rules to allow outside access to the DMZ only to specific destinations using HTTP, FTP, or SMTP.

Isolating and Protecting Internal Networks

You can use a vShield Edge with the Port Group Isolation feature to isolate an internal network from the

external network. A vShield Edge provides perimeter firewall protection and edge services to secure virtual

machines in a port group, enabling communication to the external network through DHCP, NAT, and VPN.

Within the secured port group, you can install a vShield App instance on each ESX host that the vDS spans to

secure communication between virtual machines in the internal network.

If you utilize VLAN tags to segment traffic, you can use App Firewall to create smarter access policies. Using

App Firewall instead of a physical firewall allows you to collapse or mix trust zones in shared ESX clusters. By

doing so, you gain optimal utilization and consolidation from features such as DRS and HA, instead of having

separate, fragmented clusters. Management of the overall ESX deployment as a single pool is less complex

than having separately managed pools.

For example, you use VLANs to segment virtual machine zones based on logical, organizational, or network

boundaries. Leveraging the Virtual Infrastructure SDK, the vShield Manager inventory panel displays a view

of your VLAN networks under the Networks view. You can build access rules for each VLAN network to

isolate virtual machines and drop untagged traffic to these machines.
