This manual, the vShield API Programming Guide, describes how to install, configure, monitor, and maintain the

VMware®vShield™ system by using REST API requests. The information includes step-by-step configuration

instructions and examples.

Intended Audience

This manual is intended for anyone who wants to use REST API to install or use vShield in a VMware

vCenter™ environment. The information in this manual is written for experienced system administrators who

are familiar with virtual machine technology and virtual datacenter operations. This manual assumes

familiarity with vShield.

VMware®vShield™ is a suite of network edge and application-aware firewalls built for VMware vCenter™

Server integration. vShield inspects client-server communications and inter-virtual-machine communication

to provide detailed traffic analytics and application-aware firewall protection. vShield is a critical security

component for protecting virtualized datacenters from attacks and misuse helping you achieve your

compliance-mandated goals.

This guide assumes you have administrator access to the entire vShield system. If you are unable to access a

screen or perform a particular task, consult your vShield administrator.

This chapter includes the following topics:

“vShield Components” on page 9

“Ports Required for vShield” on page 10

“An Introduction to REST API for vShield Users” on page 10

vShield Components

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

through a web-based user interface, a command line interface (CLI), and REST API.

To run vShield, you need one vShield Manager virtual machine and at least one vShield Zones, vShield App,

or vShield Edge virtual machine.

vShield Manager

The vShield Manager is the centralized management component of vShield and is installed from OVA as a

virtual machine by using the vSphere Client. Using the vShield Manager user interface or vSphere Client

plug-in, administrators can install, configure, and maintain vShield components.

The vShield Manager virtual machine can run on a different ESX host from your vShield App and vShield

Edge virtual machines.

The vShield Manager user interface leverages the VMware Infrastructure SDK to display a copy of the vSphere

Client inventory panel.

For more on the using the vShield Manager user interface, see the vShield Administration Guide.

vShield App

A vShield App monitors all traffic into and out of an ESX host, and between virtual machines on the host.

vShield App provides application-aware traffic analysis and stateful firewall protection. vShield App

regulates traffic based on a set of rules, similar to an access control list (ACL).

Overview of VMware vShield 1

vShield API Programming Guide

10 VMware, Inc.

As traffic passes through a vShield App, each session header is inspected to catalog the data. The vShield App

creates a profile for each virtual machine detailing the operating system, applications, and ports used in

network communication. Based on this information, the vShield App allows ephemeral port usage by

permitting dynamic protocols such as FTP and RPC to pass through, while maintaining lockdown on ports

1024 and higher.

You cannot protect the Service Console or VMkernel with a vShield App because these components are not

virtual machines.

vShield Edge

A vShield Edge provides network edge security to protect the virtual machines in a vCloud tenant’s network

from attacks originating from the public network. The vShield Edge connects the isolated, private networks of

cloud tenants to the public side of the service provider network through common edge services such as DHCP,

VPN, NAT, and load balancing.

You install a vShield Edge from the vShield Manager. You can install one vShield Edge instance per tenant port

group on a vNetwork Distributed Switch (vDS).

You configure a vShield Edge by using REST API.

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.

Ports Required for vShield

The vShield Manager requires ports 80/TCP and 443/TCP for REST API requests.

An Introduction to REST API for vShield Users

REST, an acronym for Representational State Transfer, is a term that has been widely employed to describe an

architectural style characteristic of programs that rely on the inherent properties of hypermedia to create and

modify the state of an object that is accessible at a URL.

How REST Works

Once a URL of such an object is known to a client, the client can use an HTTP GET request to discover the

properties of the object. These properties are typically communicated in a structured document with an HTTP

Content-Type of XML or JSON, that provides a representation of the state of the object. In a RESTful workflow,

documents (representations of object state) are passed back and forth (transferred) between a client and a

service with the explicit assumption that neither party need know anything about an entity other than what is

presented in a single request or response. The URLs at which these documents are available are often “sticky,”

in that they persist beyond the lifetime of the request or response that includes them. The other content of the

documents is nominally valid until the expiration date noted in the HTTP Expires header.
