Introduction

This Administrator’s Guide describes both the PGP Universal™ Server and Client software. 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 high-level overview of PGP Universal Server.

What is PGP Universal Server?

PGP Universal Server is a single console for managing the applications that provide email, disk, and network file encryption.

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.

PGP Universal Server 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).

PGP Desktop, a client product, is created and managed through PGP Universal Server policy. It creates PGP keypairs and can manage user keypairs as well as store the public keys of others. It encrypts user email and instant messaging (IM). It can encrypt entire or partial hard drives. It also enables secure file sharing with others over a network.

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 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 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 implement and maintain your organization’s PGP Universal Server environment. These are the PGP Universal Server administrators.

This guide is also intended for anyone else who wants to learn about how PGP Universal Server works.

To be Common Criteria compliant, please refer to the best practices shown in PGP Universal Server 2.9 Common Criteria Supplemental. Note that these best practices supersede recommendations made elsewhere in this and other documentation.

PGP Universal™ Server Introduction

Improvements in this Version of PGP Universal Server

The 3.0.0 release of PGP Universal Server introduces the following new and improved features:

General

 Client policy management changes: Internal users, external users, PGP

Verified Directory users, and devices are now called consumers. Consumers are sorted into groups manually, by user type, or by matching consumer attributes to domains, dictionary entries or through LDAP values. Group membership determines which policy consumers receive.

 Expanded directory synchronization: The integrated directory

synchronization feature now connects to multiple LDAP directories. Previous versions of PGP Universal Server could only connect to one corporate directory at a time.

 Managed PGP Mobile: PGP Universal Server now manages client policy

for PGP Mobile installations.

 Operating system change: The new CentOS operating system improves

scalability and reliability, and supports a wider variety of hardware.

 RSA SecurID support for administrator authentication: PGP Universal

Server now supports two-factor authentication using RSA SecurID. This meets strong authentication requirements for environments with higher security needs, and is compatible with existing RSA SecurID deployments.

PGP Keys

 Key Management Server (KMS): The new key management feature

provides new and expanded key management capabilities for PGP products. Key policy changes are now immediately enforced. KMS allows management of asymmetric and symmetric keys. The API and SDK provide key management functionality to non-PGP applications.

 Server Key Mode offline use: The client can now store the SKM private

key, encrypted to a random passphrase, so users can read email offline.

PGP Messaging

 ADK archival output: Administrators can archive end-to-end encrypted

email messages by decrypting the messages on PGP Universal Server using the ADK, and sending the decrypted messages to an archive server. Encrypted email messages are then searchable, making possible compliance with regulatory mandates and requirements for message retention, mail server data management, and legal discovery support.

PGP Universal™ Server Introduction

 Recursive encoding: Provides an additional layer of protection to email

messages that have been partially protected and to email messages that have been signed. Supports an additional layer of encoding if the initial layer is not complete.

Clustering

 New clustering functionality: Cluster members now interact with each

other as peers, replacing the previous Primary/Secondaries model. Every server in a cluster can serve all types of requests, and any server can initiate persistent changes. The new cluster model also permits up to 20 nodes in a cluster.

Using the PGP Universal Server with the Command Line

Using the PGP Universal Server command line for read-only access (such as to view settings, services, logs, processes, disk space, query the database, etc) is supported. However, performing configuration modifications via the command line voids your PGP Support agreement unless these procedures are followed.

Symbols

Any changes made to the PGP Universal Server via the command line must be:

 Authorized in writing by PGP Support.

 Implemented by a PGP Partner, reseller or internal employee who is

certified in the PGP Advanced Administration and Deployment Training.

 Summarized and documented in a text file in

/var/lib/ovid/customization on the PGP Universal Server itself.

Changes made through the command line might not persist through reboots and might be incompatible with future releases. PGP Support can require reverting any custom configurations on the PGP Universal Server back to a default state when troubleshooting new issues.

Notes, Cautions, and Warnings are used in the following ways.

Note: Notes are extra, but important, information. A Note calls your attention

to important aspects of the product. You can use the product better if you read the Notes.

PGP Universal™ Server Introduction

Caution: Cautions indicate the possibility of loss of data or a minor security

breach. A Caution tells you about a situation where problems can occur unless precautions are taken. Pay attention to Cautions.

Warning: Warnings indicate the possibility of significant data loss or a major

security breach. A Warning means serious problems will occur unless you take the appropriate action. Please take Warnings very seriously.

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.

Important Terms

The following sections define important terms you will encounter throughout the PGP Universal Server and this documentation.

PGP Products

 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 Global Directory: A free, public keyserver hosted by PGP

Corporation. The PGP Global Directory provides quick and easy access to the universe of PGP keys. It uses next-generation keyserver technology that queries the email address on a key (to verify that the owner of the email address wants their key posted) and lets users manage their own keys. Using the PGP Global Directory significantly enhances your chances of finding a valid public key of someone to whom you want to send secured messages.

For external users without encryption keys, PGP Universal Server offers multiple secure delivery options, leveraging third-party software that is already installed on typical computer systems, such as a web browser or Adobe Acrobat Reader. For email recipients who do not have an encryption solution, you can use of of the following secure delivery options from PGP Universal Server:

 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 keys on their local computers (if allowed by the administrator).

PGP Universal™ Server The Big Picture

 PGP Universal Web Messenger: The PGP Universal Web Messenger

service allows an external user to securely read a message from an internal user before the external user has a relationship with the SMSA. If PGP Universal Web Messenger is available via mail policy for a user and the recipient’s key cannot be found, the message is stored on the PGP Universal Server and an unprotected message is sent to the recipient. The unprotected message includes a link to the original message, held on the PGP Universal Server. The recipient must create a passphrase, and then can access his encrypted messages stored on PGP Universal Server.

 PDF Messenger: PDF Messenger enables sending encrypted PDF

messages to external users who do not have a relationship with the SMSA. In the normal mode, as with PGP Universal Web Messenger, the user receives a message with a link to the encrypted message location and uses a PGP Universal Web Messenger passphrase to access the message. PDF Messenger also provides Certified Delivery, which encrypts the message to a one-time passphrase, and creates and logs a delivery receipt when the user retrieves the passphrase.

 PGP Desktop: A client software tool that uses cryptography to protect your

data against unauthorized access. PGP Desktop is available for Mac OS X and Windows.

 PGP Whole Disk Encryption: Whole Disk Encryption is a feature of

PGP Desktop that encrypts your entire hard drive or partition (on Windows systems), including your boot record, thus protecting all your files when you are not using them.

 PGP NetShare: A feature of PGP Desktop for Windows with which

you can securely and transparently share files and folders among selected individuals. PGP NetShare users can protect their files and folders simply by placing them within a folder that is designated as protected.

 PGP Virtual Disk: PGP Virtual Disk volumes are a feature of PGP

Desktop that let you use part of your hard drive space as an encrypted virtual disk. You can protect a PGP Virtual Disk volume with a key or a passphrase. You can also create additional users for a volume, so that people you authorize can also access the volume.

 PGP Zip: A feature of PGP Desktop that lets you put any combination

of files and folders into a single encrypted, compressed package for convenient transport or backup. You can encrypt a PGP Zip archive to a PGP key or to a passphrase.

 PGP Portable: A separately-licensed feature that enables you to send

encrypted files to users who do not have PGP Desktop software, and to transport files securely to systems that do not or cannot have PGP software installed.

PGP Universal™ Server The Big Picture

PGP Universal Server Concepts

 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.

Corporation strongly recommends you name your externally visible

PGP 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.

For more information, see Naming your PGP Universal Server (on page

 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).

PGP Universal Server Features

 Administrative Interface: Each PGP Universal Server is controlled via a

Web-based administrative interface. The administrative interface gives you control over PGP Universal Server. 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.

 Backup and Restore: Because full backups of the data stored on your PGP

Universal Server are critical in a natural disaster or other unanticipated loss of data or hardware, you can schedule automatic backups of your PGP Universal Server data or manually perform a backup.

You can fully restore a PGP Universal Server from a backup. In the event of a minor problem, you can restore the PGP Universal Server to any saved backup. In the event that a PGP Universal Server is no longer usable, you can restore its data from a backup onto a new PGP Universal Server during initial setup of the new PGP Universal Server using the Setup Assistant. All backups are encrypted to the Organization Key and can be stored securely off the PGP Universal Server.

37).

 Cluster: When you have two or more PGP Universal Servers in your

network, you configure them to synchronize with each other; this is called a “cluster.”

 Dictionary: Dictionaries are lists of terms to be matched. The dictionaries

work with mail policy to allow you to define content lists that can trigger rules.

PGP Universal™ Server The Big Picture

 Directory Synchronization: If you have LDAP directories in your

organization, your PGP Universal Server can be synchronized with the directories. The PGP Universal Server automatically imports user information from the directories when users send and receive email; it also creates internal user accounts for them, including adding and using X.509 certificates if they are contained in the LDAP directories.

 Ignition Keys: You can protect the contents of a PGP Universal Server,

even if the hardware is stolen, by requiring the use of a hardware token or a software passphrase, or both, on start.

 Keyserver: Each PGP Universal Server includes an integrated keyserver

populated with the public keys of your internal users. When an external user sends a message to an internal user, the external PGP Universal Server goes to the keyserver to find the public key of the recipient to use to secure the message. The PGP Universal Server administrator can enable or disable the service, and control access to it via the administrative interface.

 Learn Mode: When you finish configuring a PGP Universal Server using

the Setup Assistant, it begins in Learn Mode, where the PGP Universal Server sends messages through mail policy without taking any action on the messages, and does not encrypt or sign any messages.

Learn Mode gives the PGP Universal Server a chance to build its SMSA (creating keys for authenticated users, for example) so that when when Learn Mode is turned off, the PGP Universal Server can immediately begin securing messages. It is also an excellent way for administrators to learn about the product.

You should check the logs of the PGP Universal Server while it is in Learn Mode to see what it would be doing to email traffic if it were live on your network. You can make changes to the PGP Universal Server’s policies while it is in Learn Mode until things are working as expected.

 Mail Policy: The PGP Universal Server processes email messages based

on the policies you establish. Mail policy applies to inbound and outbound email processed by both PGP Universal Server and client software. Mail policy consists of multiple policy chains, comprised of sequential mail processing rules.

 Organization Certificate: You must create or obtain an Organization

Certificate to enable S/MIME support by PGP Universal Server. The Organization Certificate signs all X.509 certificates the server creates.

 Organization Key: The Setup Assistant automatically creates an

Organization Key (actually a keypair) when it configures a PGP Universal Server. The Organization Key is used to sign all PGP keys the PGP Universal Server creates and to encrypt PGP Universal Server backups.

PGP Universal™ Server The Big Picture

Caution: It is extremely important to back up your Organization Key: all

keys the PGP Universal Server creates are signed by the Organization Key, and all backups are encrypted to the Organization Key. If you lose your Organization Key and have not backed it up, the signatures on those keys are meaningless and you cannot restore from backups encrypted to the Organization Key.

 PGP Verified Directory: The PGP Verified Directory supplements the

internal keyserver by letting internal and external users manage the publishing of their own public keys. The PGP Verified Directory also serves as a replacement for the PGP Keyserver product. The PGP Verified Directory uses next-generation keyserver technology to ensure that the keys in the directory can be trusted.

 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.

For more information, see Configuring Mail Proxies (on page PGP Universal Server Installation Guide.

 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.

PGP Universal Server User Types

 Administrators: Any user who manages the PGP Universal Server and its

security configuration from inside the internal network.

Only administrators are allowed to access the administrative interface that controls PGP Universal Server. A PGP Universal Server supports multiple administrators, each of which can be assigned a different authority: from read-only access to full control over every feature and function.

 Consumers: Internal, external, and Verified Directory users, and devices.

 External Users: External users are email users from other domains

(domains not being managed by your PGP Universal Server) who have been added to the SMSA.

171) and the

PGP Universal™ Server The Big Picture

 Internal Users: Internal users are email users from the domains being

managed by your PGP Universal Server.

PGP Universal Server allows you to manage PGP Desktop deployments to your internal users. The administrator can control which PGP Desktop features are automatically implemented at install, and establish and update security policy for PGP Desktop users that those users cannot override (except on the side of being more secure).

 PGP Verified Directory Users: Internal and external users who have

submitted their public keys to the PGP Verified Directory, a Webaccessible keyserver.

 Devices: Managed devices, WDE computers, and WDE disks.

Managed devices are arbitrary objects whose keys are managed by PGP Universal Server. WDE computers, and WDE disks are devices that are detected when users enroll.

 Other Email Users: Users within your organization can securely send

email to recipients outside the SMSA.

First, the PGP Universal Server attempts to find a key for the recipient. If that fails, there are four fallback options, all controlled by mail policy: bounce the message back to the sender (so it is not sent unencrypted), send unencrypted, Smart Trailer, and PGP Universal Web Messenger mail.

Smart Trailer sends the message unencrypted and adds text giving the recipient the option of joining the SMSA by installing PGP Universal Satellite, using an existing key or certificate, or using PGP Universal Web Messenger. PGP Universal Web Messenger lets the recipient securely read the message on a secure website; it also gives the recipient options for handling subsequent messages from the same domain: read the messages on a secure website using a passphrase they establish, install PGP Universal Satellite, or add an existing key or certificate to the SMSA.

Installation Overview

The following steps are a broad overview of what it takes to plan, set up, and maintain your PGP Universal Server environment.

Most of the steps described here are described in detail in later chapters. Steps 1 and 4 are described in the PGP Universal Server Installation Guide. Note that these steps apply to the installation of a new, stand-alone PGP Universal Server.

If you plan to install a cluster, you must install and configure one PGP Universal Server following the steps outlined here. Subsequent cluster members will get most of their configuration settings from the initial server by replication.

The steps to install and configure a PGP Universal Server are as follows:
