Introducing McAfee Endpoint Encryption for

Files and Folders

McAfee Endpoint Encryption for Files and Folders (EEFF) offers data protection in the form of

powerful encryption technology so that only authorized users can access information.

System requirements

About this guide

Why EEFF?

EEFF offers enhanced security to protect your data. EEFF depends on Microsoft Windows user

accounts and works in real-time to authenticate user to access encryption keys and to retrieve

the correct policy in EEFF. A smart card implementation based on Windows logon can be used

for enhanced security.

Endpoint Encryption for Files and Folders allows you to define and protect information in a way

that only certain users can access it. This data is stored, managed, archived, and distributed

as any other file is, however, it can be viewed only by those who have been granted access.

Endpoint Encryption for Files and Folders is a Persistent Encryption engine: when a file has

been encrypted and has been moved or copied to another place, it remains encrypted. If a file

is moved out of an encrypted directory, it will also remain encrypted. Likewise, if an encrypted

file is moved to a memory stick – the encryption will remain in place.

EEFF integrates with McAfee ePolicy Orchestrator (ePO), which provides a single point of control

over all the data on the systems. EEFF with ePO supports both user-based and system-based

policies. Assigning these policies to users encrypts the data on the client as configured.

EEFF depends on Microsoft Windows credentials therefore, both registered domain users and

local system users can be assented encryption policies and associated keys.

How EEFF 4.0 works

EEFF encrypts folders and files according to policies assigned to the user. These policies are

enforced by the ePO server.

5McAfee Endpoint Encryption for Files and Folders version 4.0.0 Product Guide

The client software is installed on the client system. After the installation, the system synchronizes

with the ePO server and acquires the user data. EEFF then assigns encryption policies and keys

to the user as configured.

EEFF client acts like a filter between the application creating or editing the files and the storage

media. When a file is saved, EEFF filter executes the assigned encryption policies and encrypts

the data, if applicable. If the user manages to kill the main EEFF process on the client system,

EEFF encrypts folders and files according to policies assigned to the user. These policies are

enforced by the ePO server.

The client software is installed on the client system. After the installation, the system synchronizes

with the ePO server and acquires the user data. EEFF then assigns encryption policies and keys

to the user as configured.

The EEFF client acts like a filter between the application creating or editing the files and the

storage media. When a file is saved, the EEFF filter executes the assigned encryption policies

and encrypts the data, if applicable. If the user manages to kill the main EEFF process

(MfeffCore.exe) on the client system, attempting to deviate from the assigned encryption policy,

the process will be automatically regenerated. The automatic restart cannot be disabled.

When a file that is encrypted with key A is moved to a folder where files are encrypted with

key B, the file encrypted with key A will immediately be re-encrypted with key B. This behavior

is known as

follow-target-encryption

and requires that the user or process transferring the file

has access to both key A and key B. This operation takes place instantly when the file is placed

in the folder encrypted with key B.

EEFF Features

•Centralized management — Provides support for deploying and managing McAfee Endpoint

Encryption for Files and Folders using ePO 4.5 and 4.6.

•Windows authentication based policy enforcement — Assigns encryption policies and

keys to Windows user accounts.

•Integration with the McAfee Tray icon - Consolidates the tray icons to one common

McAfee icon.

•User Personal Keys - Allow users to have individual keys, generated centrally and possible

to assign in policies for encryption.

•Protect data on Removable media — Provides support for removable media encryption.

•Migration from EEFF v3.x to EEFF v4 - Provides support for migrating keys from EEFF

v3.x to EEFF v4 by importing them into ePO.

•File Extension exclusion - Excludes the listed file types from encryption. For example,

MP3 and WAV files.
