Introduction
This Administrator’s Guide describes both the PGP Universal Server and PGP
Universal Satellite. It tells you how to get them up and running on your network,
how to configure them, and how to maintain them. This section provides a highlevel overview of PGP Universal Server.
In This Chapter

Using the PGP Universal Server with the Command Line.......................22
PGP Universal Server provides multiple encryption solutions managed from a
single console.
PGP Universal Server with PGP Universal Gateway Email gives you secure
messaging: it transparently protects your enterprise messages with little or no
user interaction.
The PGP Universal Server also replaces the PGP Keyserver product with a builtin keyserver, and the PGP Admin product with PGP Desktop configuration and
deployment capabilities.
It automatically creates and maintains a Self-Managing Security Architecture
(SMSA) by monitoring authenticated users and their email traffic. You can also
send protected messages to addresses that are not part of the SMSA. The PGP
Universal Server encrypts, decrypts, signs, and verifies messages automatically,
providing strong security through policies you control.
PGP Universal Satellite, a client-side feature of PGP Universal Server, extends
PGP security for email messages all the way to the computer of the email user,
it allows external users to become part of the SMSA, and it gives end users the
option to create and manage their keys on their own computer (if allowed by
the PGP administrator).
15
PGP Universal Server Introduction
PGP Universal Server Product Family
PGP Universal Server functions as a management console for a variety of
encryption solutions. You can purchase any of the PGP Desktop applications or
bundles and use PGP Universal Server to create and manage client installations.
You can also purchase a license that enables PGP Gateway Email to encrypt
email in the mailstream.
The PGP Universal Server can manage any combination of PGP encryption
applications. PGP encryption applications are:
PGP Universal Gateway Email provides automatic email encryption in the
gateway, based on centralized mail policy. This product requires
administration by the PGP Universal Server.
PGP Desktop Email provides encryption at the desktop level for mail, files,
and AOL Instant Messenger traffic. This product can be managed by the
PGP Universal Server.
PGP Whole Disk Encryption provides encryption at the desktop level for
an entire disk. This product can be managed by the PGP Universal Server.
PGP NetShare provides transparent file encryption and sharing among
desktops. This product can be managed by the PGP Universal Server.
Who Should Read This Guide
This Administrator’s Guide is for the person or persons who will be
implementing and maintaining your organization’s PGP Universal Server
environment. These are the PGP administrators.
This guide is also intended for anyone else who wants to learn about how PGP
Universal Server works.

PDF Messenger and certified delivery. PGP Universal Gateway Email
enables users to send secure content to recipients who do not have PGP
software installed using Portable Document Format (PDF). PGP Universal
Gateway Email can encrypt existing PDFs sent by the user, or also create
secure PDFs out of normal email content. The design of this system
enables secure delivery certification, ensuring that successful delivery of
the message content to the recipient can be recorded at the PGP Universal
Server if selected by an Administrator. This feature is designed to deliver
through email documents containing confidential information; for example,
bank statements.

IMAP speed improvements. This release of PGP Universal Server
contains significant IMAP performance improvements. Users will
experience quicker responses and shorter downloads, particularly when
accessing large mailboxes, switching between folders, and checking for
new messages.
Web Messenger connectivity over HTTP. The PGP Universal Gateway
Email administrator can configure Web Messenger to accept connections
over HTTP, enabling interoperability with HTTPS accelerator products.
Services>Web Messenger

Improved handling of malformed email messages. PGP Universal
administrators have greater control in specifying how to handle malformed
email messages not in compliance with Internet standards. When a mail
message cannot be parsed in the course of evaluating mail policy,
processing immediately jumps to a special chain, designated as the
“Exception Chain.” This chain has limited capabilities, but allows the
administrator to specify what to do with the malformed mail based on
information outside of the mail itself (what interface it came in on, what
port, and so on).

Microsoft Cryptographic Application Programming Interface (CAPI)
credentials, enabling the user to make use of existing X.509 certificates
directly from the Microsoft operating system certificate store. PGP
Universal administrators can specify automatic enrollment of such
certificates as well.

Weak-cipher decryption. PGP products now decrypt S/MIME encoded
messages encrypted with weak 40-bit RC2 encryption for backwards
compatibility with older email clients. Additional warnings are added to
messages decrypted using that algorithm. Note that PGP Universal Server
will not encrypt using weak ciphers.
PGP NetShare per-folder administration. PGP NetShare administrative
granularity has been extended to restrict administrator control to a perfolder level, thus limiting administrative access to exactly where it is
needed.

Advanced centralized event logging. PGP Universal now provides
significantly expanded reporting on PGP Whole Disk Encryption usage on
client systems. This logging feature itemizes events such as which
systems have been encrypted, the progress of encryption or decryption for
an individual system, errors encountered during encryption, the status of
recovery tokens, removable storage usage, and failed/successful login
attempts. Administrators can set thresholds that raise alerts in PGP
Universal on the PGP Daily Status Email or dashboard screen after a
configured number of failed logins has been exceeded.

Group administration access tokens. PGP Whole Disk Encryption admin
accounts can be added, allowing an administrator with a smart card key to
override the BootGuard prompt. This key can be specified separately for
each Internal User Policy. Using a single keypair copied to multiple smart
cards (each with its own PIN), an organization can enable multiple
administrators for each Policy.

Domain administrator restart bypass. Windows System and
Administrator account(s) may now engage a mode to bypass WDE
authentication on the next restart by utilizing the privileges of the
administration account to act as the authenticated user. This feature
enables administrators to perform remote software installations requiring a
restart of the target computer. Use of this feature is logged to the PGP
Universal server.

Lenovo laptop Recovery button. PGP Whole Disk Encryption now
provides complete support for the Lenovo Rescue and Recovery software
(version 3.x and 4.x) including using the “Access IBM” blue button for
boot-level recovery of the OS even when the disk (or partition) is
encrypted.
User Interface modifications for ADA compliance. As part of our
expanding support for the Americans with Disabilities Act (ADA) standards
for accessible design, the PGP WDE BootGuard screen has been modified
to provide audible feedback when the screen is ready for user input, when
a user types in an incorrect password, and when a user types a correct
password. This audio feedback is optional, configurable using PGP
Universal for managed clients.

Microsoft Windows PE support. PGP Desktop provides administrators
with the ability to create a Windows PE (Preinstallation Environment) boot
disk containing a subset of PGP Whole Disk Encryption. This bootable disc
can be used to perform a variety of management and recovery tasks.
Trusted Platform Module (TPM) support for PGP WDE. PGP Desktop
supports using the Trusted Platform Module as an additional authentication
device for PGP Whole Disk Encryption if present on the motherboard and
enabled via proper driver installation for your hardware. When use of the
TPM is specified prior to encryption, the user can authenticate to the disk
only on that particular machine, locking the disk to the machine hardware
and thus deterring attacks such as hard disk theft. This feature works with
passphrase users only and is compatible with the PGP WDE Single Sign-On
feature.

The Big Picture
This chapter describes some important terms and concepts and gives you a
high-level overview of the things you need to do to set up and maintain your
PGP Universal Server environment.
In This Chapter
Important Terms.......................................................................................25
PGP Universal Server: A device you add to your network that provides
secure messaging with little or no user interaction. The PGP Universal
Server automatically creates and maintains a security architecture by
monitoring authenticated users and their email traffic. You can also send
protected messages to addresses that are not part of the security
architecture.
PGP Universal Satellite: The PGP Universal Satellite software resides on
the computer of the email user. It allows email to be encrypted end to end,
all the way to and from the desktop (for both internal and external users).
Using PGP Universal Satellite is one of the ways for external users to
participate in the SMSA. It also allows users the option of controlling their
PGP Universal Server Concepts
keys on their local machines (if allowed by the PGP administrator).
Security Architecture: Behind the scenes, the PGP Universal Server
creates and manages its own security architecture for the users whose
email domain it is securing. Because the security architecture is created
and managed automatically, we call this a self-managing security
architecture (SMSA).
25
PGP Universal Server The Big Picture
keys.<domain> convention: PGP Universal Server automatically looks for
valid public keys for email recipients at a special hostname, if no valid
public key is found locally to secure a message. This hostname is
keys.<domain> (where <domain> is the email domain of the recipient). For
example, Example Corporation’s externally visible PGP Universal Server is
named keys.example.com.
PGP Corporation strongly recommends you name your externally visible
PGP Universal Server according to this convention because it allows other
PGP Universal Servers to easily find valid public keys for email recipients in
your domain.
Refer to Naming your PGP Universal Server (on page
information about this convention.
PGP Universal Server Features
Server Placement: A PGP Universal Server can be placed in one of two
locations in your network to process email.
With an internal placement, the PGP Universal Server logically sits between
your email users and your mail server. It encrypts and signs outgoing SMTP
email and decrypts and verifies incoming mail being picked up by email
clients using POP or IMAP. Email stored on your mail server is stored
secured (encrypted).
With a gateway placement, the PGP Universal Server logically sits between
your mail server and the Internet. It encrypts and signs outgoing SMTP
email and decrypts and verifies incoming SMTP email. Email stored on your
mail server is stored unsecured.
Refer to Adding the PGP Universal Server to Your Network (on page
and Configuring Mail Proxies (on page
server placement.
Administrative Interface: Each PGP Universal Server is controlled via a
Web-based administrative interface. The administrative interface gives you
control over the PGP Universal Server’s operation. While many settings are
initially established using the web-based Setup Assistant, all settings of a
PGP Universal Server can be controlled via the administrative interface.
59) for more
35)
219) for more information about
Setup Assistant: When you attempt to log in for the first time to the
administrative interface of a PGP Universal Server, the Setup Assistant
takes you through the configuration of that PGP Universal Server.
Learn Mode: When you finish configuring a PGP Universal Server using
the Setup Assistant, it begins operation in Learn Mode, which is a special
mode where the PGP Universal Server proxies traffic normally but does not
encrypt or sign any messages.
