Table 1 – ST Organization and Section Descriptions Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 7 of 40 1.4 Document Conventions The notation, formatting, and conventions used in this Security Target are consistent with those used in Version 3.1 of the Common Criteria. Selected presentation choices are discussed here to aid the Security Target reader. The Common Criteria allows several operations to be performed on functional requirements: The allowable operations defined in Part 2 of the Common Criteria are refinement, selection, assignment and iteration.  The assignment operation is used to assign a specific value to an unspecified parameter, such as the length of a password. An assignment operation is indicated by italicized text.  The refinement operation is used to add detail to a requirement, and thus further restricts a requirement. Refinement of security requirements is denoted by bold text. Any text removed is indicated with a strikethrough format (Example: TSF).  The selection operation is picking one or more items from a list in order to narrow the scope of a component element. Selections are denoted by underlined text.  Iterated functional and assurance requirements are given unique identifiers by appending to the base requirement identifier from the Common Criteria an iteration number inside parenthesis, for example, FIA_UAU.1.1 (1) and FIA_UAU.1.1 (2) refer to separate instances of the FIA_UAU.1 security functional requirement component. Outside the SFRs, italicized text is used for both official document titles and text meant to be emphasized more than plain text. 1.5 Document Terminology The following table describes the terms and acronyms used in this document: TERM DEFINITION CC Common Criteria version 3.1 (ISO/IEC 15408) CPU Central Processing Unit DBMS DataBase Management System EAL Evaluation Assurance Level EMM Enterprise Mobility Management GUI Graphical User Interface I&A Identification & Authentication IIS Internet Information Services IP Internet Protocol IT Information Technology OS Operating System OSP Organizational Security Policy PP Protection Profile RAM Random Access Memory SF Security Function Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 8 of 40 TERM DEFINITION SFP Security Function Policy SFR Security Functional Requirement SQL Structured Query Language SSL Secure Socket Layer ST Security Target TOE Target of Evaluation TSC TOE Scope of Control TSF TOE Security Function VGA Video Graphics Array Table 2 – Terms and Acronyms Used in Security Target 1.6 TOE Overview The McAfee EMM platform provides secure management of mobile devices. McAfee EMM allows the integration of smart mobile devices into enterprise networks with the same level of security protection enabled on laptops and desktops. With McAfee EMM, System Administrators have the tools and capabilities needed to effectively secure mobile devices in the enterprise network, seamlessly manage them in a scalable architecture, and efficiently assist users when problems arise. McAfee EMM is a web-based solution that helps manage the entire life cycle of the mobile device. McAfee EMM’s combination of device management, network control and compliance reporting delivers a powerful mobile device security solution. Note that the scope of the TOE covers the management element only, and does not include software on the mobile devices themselves. The following sections provide a summary of the specific TOE sub-components. Note that communication between the distributed components of the TOE is protected from disclosure and modification by cryptographic functionality provided by the operational environment. 1.6.1 McAfee EMM Hub The McAfee EMM Hub component manages communication between components. The Hub allows secure communication across the firewall (between the DMZ and the internal network) and eliminates the need to open custom firewall ports. SSL communication is established between the components. The EMM Hub interacts with both ePO and the EMM database to extract details of policies for managed mobile devices. 1.6.2 McAfee EMM Portal The McAfee Client Application (out of scope) connects to the EMM Portal to request the policy for the device. The McAfee EMM Portal (EMM Portal) allows device users to initiate wipe requests via a browser in the event their device is lost or stolen. This component should be installed in the DMZ. Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 9 of 40 1.6.3 McAfee EMM Proxy The EMM Proxy is an IIS (Internet Information Services) application that controls access to enterprise resources on the DMZ server before reaching the internal network. The McAfee EMM Proxy proxies ActiveSync traffic between mobile device email clients and the internal email servers. This component should be installed in the DMZ. 1.6.4 McAfee EMM Push Notifier The Push Notifier sends notifications to the managed mobile devices, prompting the device to connect back to the EMM Portal. This is done via the Apple and Google push notification services in the cloud. This component should be installed in the DMZ. 1.6.5 ePolicy Orchestrator ePO provides the central management interface and functionality for the administrators of the TOE. It also provides reporting and policy storage capabilities, all through a single point of control. An extension to ePO provides EMM specific management features. Mobile ePO provides communication between ePO and the EMM Hub. 1.7 TOE Description 1.7.1 Physical Boundary The TOE is a software TOE and includes the EMM Server components listed below executing on general purpose computing platforms: a. McAfee EMM Hub b. McAfee EMM Portal c. McAfee EMM Proxy d. McAfee EMM Push Notifier e. McAfee ePO with EMM extension and MePO Note specifically that the hardware, operating systems and third party support software (e.g. DBMS) on each of the systems are excluded from the TOE boundary. The Portal, Proxy and Push Notifier can operate on a single platform in the DMZ. The Hub, ePO and database servers would normally be on separate platforms within the internal network. In order to comply with the evaluated configuration, the following hardware and software components should be used: Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 10 of 40 TOE COMPONENT VERSION/MODEL NUMBER TOE Software EMM Server Version 12.0.780.52882 McAfee ePO 5.1.0 build 509 with hotfixes 1, 960279-2, 962156 and 973112 McAfee EMM 12.0 build 12.0.0.1073 McAfee EMM help 12.0.0.022 Operational Environment McAfee EMM App (iOS and Android devices) Version 4.9.1 McAfee EMM Secure Container (Android devices) App Version 2.3.93 Hardware specified in the following:  Table 4 – Management System Component Requirements  Table 5 – Supported Mobile Platforms Table 3 – Evaluated Configuration for the TOE The evaluated configuration consists of a single instance of the management system (comprised of the EMM Server, EMM Hub and EMM DMZ Server) and one or more instances of managed systems running the McAfee EMM Client App. The following figure presents an example of an operational configuration. Figure 1 – TOE Boundary Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 11 of 40 1.7.2 Hardware and Software Supplied by the Operational Environment The TOE is a software TOE. The hardware, operating systems and all third party support software (e.g., DBMS) on the systems on which the TOE executes are excluded from the TOE boundary. The platforms on which the EMM Server software is installed must be dedicated to functioning as the management system. EMM Server operates as a distribution system and management system for a client-server architecture offering components for the server part of the architecture (not the clients). The TOE requires the following hardware and software configuration on these management platforms: COMPONENT MINIMUM REQUIREMENTS Processor Dual core CPU Memory 4 GB RAM Free Disk Space 1 GB Monitor 1024x768, 256-color, VGA monitor or higher Operating System  Windows Server 2008 64‑bit with Service Pack 2 (Standard or Enterprise Edition)  Windows Server 2008 R2 64‑bit with Service Pack 1 (Standard or Enterprise Edition) DBMS  Microsoft SQL Server 2005 with Service Pack 3 or later (Enterprise, Standard, or Workgroup Edition)  Microsoft SQL Server 2008 R2 32‑ and 64‑bit with Service Pack 1 or later (Enterprise, Standard, or Workgroup Edition) Web Browser  Internet Explorer 8.0 or later  Firefox 10.0 or later  Chrome 17 or later Table 4 – Management System Component Requirements The McAfee EMM Client App executes on one or more systems whose policy settings are to be audited and enforced by the operating system.

TSF DESCRIPTION Identification and Authentication On the management system, the TOE requires administrators to identify and authenticate themselves before accessing the ePO software. No action can be initiated before proper identification and authentication. Each TOE administrator has security attributes associated with their user account that define the functionality the user is allowed to perform. On the user portal, the TOE requires users to identify and authenticate themselves before accessing the Portal software. No action can be initiated before proper identification and authentication. Management The TOE’s Management Security Function provides support functionality that enables users to configure and manage TOE components. Management of the TOE is performed via the ePO GUI. Management privileges are defined per-user. Audit The TOE’s Audit Security Function provides auditing of management actions performed by administrators. Authorized users may review the audit records via ePO Audit. Policy Management The TOE pushes policies to managed systems (i.e., mobile devices). These policies dictate allowed features and functions and are specified by an administrator through an access control policy.

Access to the TOEis determined using an identification and authentication process (FIA_UID.1 and FIA_UAU.1) at either ePO or the EMM portal. The permitted access to TOE data and functions by authorized administrators at ePO is determined by the defined roles and permissions (FMT_MTD.1, FMT_SMF.1, FMT_SMR.1). The permitted access to TOE data and functions by EMM Portal users is determined by the assigned user access policy. O.AUDITS The TOE must record audit records for data accesses and use of the System functions. Security-relevant events must be defined and auditable for the TOE (FAU_GEN.1). The user associated with the events must be recorded (FAU_GEN.2). O.EADMIN The TOE must include a set of functions that allow effective management of its functions and data. The functions and roles required for effective management are defined (FMT_SMF.1, FMT_SMR.1), and the specific access privileges for the roles and permissions is enforced (FMT_MTD.1). Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 30 of 40 OBJECTIVE RATIONALE O.IDAUTH The TOE must be able to identify and authenticate users and administrators prior to allowing access to TOE functions and data. Security attributes of subjects used to enforce the security policy of the TOE must be defined (FIA_ATD.1). Users authorized to access the TOE are determined using an identification and authentication process (FIA_UID.1 and FIA_UAU.1). O.INTEGRITY The TOE must ensure the integrity of all System data. Only authorized administrators of the System may query or add System data (FMT_MTD.1). O.MOBILE_POLICY The TOE must create policy data that may be used by the environment to enforce the access to and features available within a controlled mobile device. The TOE shall create policies that are used by the environment to enforce access to and features available within a controlled mobile device. (FDP_ACC.1, FDP_ACF.1). The default values of security attributes are restrictive in nature (FMT_MSA.3).

The TOE provides, via review of vendor-supplied evidence, independent confirmation that these actions have been competently performed. The general level of assurance for the TOE is: 1. Consistent with current best commercial practice for IT development and provides a product that is competitive against non-evaluated products with respect to functionality, performance, cost, and time-to-market. 2. The TOE assurance also meets current constraints on widespread acceptance, by expressing its claims against EAL2 from part 3 of the Common Criteria. 3. Consistent with current best practice for tracking and fixing flaws as well as providing fixes to customers. 6.5 TOE Summary Specification Rationale This section demonstrates that the TOE’s Security Functions completely and accurately meet the TOE SFRs. The following tables provide a mapping between the TOE’s Security Functions and the SFRs and the rationale.

FAU_GEN.2 Audit – The audit log records include the associated user name when applicable. FDP_ACC.1 Policy Management – The TOE implements policy-based access control to restrict actions available on managed devices. FDP_ACF.1 Policy Management – The TOE implements policy-based access control to restrict actions available on managed devices. FIA_ATD.1 Management – User security attributes are associated with the administrative user/EMM Portal user upon successful login. FIA_UID.1 Identification and Authentication – The TSF requires users to identify and authenticate themselves before invoking any other TSF function or before viewing any TSF data via an interface. No action at either ePO or EMM portal can be initiated before proper identification and authentication. FIA_UAU.1 Identification and Authentication – The TSF requires users to identify and authenticate themselves before invoking any other TSF function or before viewing any TSF data via an interface. No action at either ePO or EMM portal can be initiated before proper identification and authentication. FMT_MSA.3 Management – The TOE ensures the default values of security attributes are permissive in nature. FMT_MTD.1 Management – The Systems Administrator and user permissions determine the access privileges of the user to TOE data. FMT_SMF.1 Management – The management functions that must be provided for effective management of the TOE are defined and described. Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 33 of 40 SFR SECURITY FUNCTION AND RATIONALE FMT_SMR.1 Management – The TOE provides the roles specified in the SFR. When an administrator account is created or modified on ePO, the role is specified by setting or clearing the appropriate permission sets for the user. EMM portal accounts are created by synchronisation with the LDAP server to import the available mailbox accounts. The permissions associated with the account are then configured through the access control policy. Table 23 – SFR to TSF Rationale Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 34 of 40 7 TOE Summary Specification 7.1 Policy Management The TOE allows policies to be defined through the management interface provided by ePO and the EMM extension. These policies are then distributed to mobile devices for compliance to network security and usage restrictions. The access control policies determine whether user access to the mobile device feature is allowed or blocked. Each device type (i.e. iOS or Android) offers different features to the user, and so each policy is based on device type. Policies include settings for allowing or blocking the mobile user’s permission to synchronize corporate data. The following two tables show parameters contained in the device-dependent policies and actions. CATEGORY DESCRIPTION OPTIONS IOS ANDROID Mail and Compliance General compliance Block mail sync for all devices assigned this policy / Determine mail sync availability based on selected options X X Configuration Configure an ActiveSync account X X Direct traffic through an EMM Proxy server X X ActiveSync endpoint X X McAfee VMS X App protection X Check jailbroken status at intervals (hours) X If ignored, number of notifications to resend X Notification resend interval X Compliance actions Unencrypted devices X X Jailbroken/rooted devices X X Devices with unverified jailbreak status X Devices with blacklisted apps X X Devices running iOS versions earlier than X Devices that don’t use McAfee Secure Container X Devices that don’t use McAfee VMS X Devices overdue for McAfee VMS scan X Devices overdue for McAfee VMS update X Devices with malware X Devices with malicious apps X Devices with suspicious apps X Passcode (Passcode and Restrictions for Android Power-on passcode Require passcode to access the device X X Allow sequential or repeat characters X Maximum number of characters X X Alphanumeric with minimum number of special characters X X Lock the device after minutes of inactivity X X Remember previous passcodes X X Require a new passcode after number of days X X Wipe the device after failed passcode attempts X X Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 35 of 40 CATEGORY DESCRIPTION OPTIONS IOS ANDROID Secure Container Passcode Require passcode to access the McAfee Secure Container X Allow sequential or repeat characters X Maximum number of characters X Alphanumeric with minimum number of special characters X Lock McAfee Secure Container after minutes of inactivity X Remember previous passcodes X Require a new passcode after number of days X Wipe McAfee Secure Container after failed passcode attempts X Restrictions(Andro id) Block camera (Android v4 and later) X Restrict untrusted TLS certificates X Allow McAfee Secure Container to sync while roaming X Allow opening attachments from McAfee Secure Container in other programs X Restrictions Restrictions iTunes explicit content X YouTube (iOS 5 only) X iTunes X Camera X Allow FaceTime X Screen capture X Automatic sync while roaming X In-App purchases X Multiplayer gaming X Voice dialing X Installing iTunes applications X Safari X Safari – Allow autofill X Safari – Display fraud warnings X Safari – Allow Javascript X Safari – Block pop-ups X Safari – Allow cookies X IOS 5 and later restrictions iTunes store access without password X iCloud backup X iCloud document synch X iCloud key-value sync X Photo stream X Untrusted TLS certificates X Siri (voice assistant) X Allow Siri when device is locked X Sending diagnostic data X Moving, forwarding or replying to corporate email using other email accounts X Sending corporate email from third party apps X IOS 6 and later restrictions Passbook when device is locked X Shared photo stream X Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 36 of 40 CATEGORY DESCRIPTION OPTIONS IOS ANDROID IOS 7 restrictions Opening documents from managed apps and accounts in unmanaged apps and accounts X Opening documents from unmanaged apps and accounts in managed apps and accounts X Roaming restrictions Roaming X Voice roaming X Data roaming X Certificates Client certificates Add/delete X Server certificates Add/delete X VPN VPN profiles Add/delete/modify X Wi-Fi Wi-Fi profiles Add/delete/modify X X APN APN settings Use custom carrier APN X Name X User name X Password X Proxy server X Proxy port X Supervised Devices App lock (iOS 6 and later) Enable app lock X App identifier X Device rotation X Auto-lock X Restrictions Game Center X iBooks X iBooks adult content X Installing certificates or configuration profiles X HTTP proxy Redirect traffic through an HTTP proxy server X Web clips Web clips Add/delete X Blacklist Application list Add/delete blacklisted apps X X Whitelist Application list Add/delete whitelisted apps X X Single sign-on Single sign-on profiles Add/delete/modify single sign-on profiles X Table 24 – Device policy configuration options The following actions are available for the authorized administrator to initiate through ePO.

All users must enter a username and password into ePO, which is validated by the TOE against the user authentication information stored by the TOE. If the authentication succeeds, the user receives a session token that is used for identification of subsequent requests during that session. If not, the login process is terminated and the login GUI is redisplayed. The TOE has the ability to identify and authenticate all EMM portal users using the user’s email address and password, which is verified by the LDAP server. If the LDAP server reports successful verification of the identification and authentication credentials, the user receives a session token that is used for identification of subsequent requests during that session. If not, the login process is terminated and the login GUI is redisplayed. 7.3 Management The TOE provides support functionality that enables an authorized administrator to configure and manage TOE components. Management of the TOE is performed via the ePO GUI. The TOE allows an authorized administrator to create, manage, and publish security policies. Available functions for administration of access policies include:  Select device settings  Assign policies to groups  Reorder Policies  Set device resource restrictions Once the authorized administrator defines one or more security policies, those policies are assigned to devices, users and or groups via ePO. The TOE provides functionality to allow authorized administrators to determine the security policy conformance of the mobile user community. ePO ensures the default values of security attributes are permissive in nature, enforcing the iOS Mobile Access Control SFP and Android Mobile Access Control SFP for the TOE. For example, the Starter Policy for iOS Mobile Access Control SFP will be default allow access to devices that are jailbroken. The TOE provides functionality to allow authorized administrators to review compliance reports in ePO. The summary reports indicate which managed devices comply with the configured access policies and which do not. The detailed reports indicate the areas of compliance/non-compliance for a particular device. Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 38 of 40 The TOE provides functionality to allow authorized administrators to unlock EMM portal user accounts, which have become locked during attempts to configure a mobile device. The table below demonstrates the roles available and the operations each role can perform on TSF data: AUTHORIZED ROLES3 TSF DATA OPERATION Global Administrator Admin Account Attributes Query, Modify, Delete Global Administrator, administrator-defined roles with “Mobile Actions: Allow unlocking users” Unlock users Execute Global Administrator, administrator-defined roles with “McAfee Enterprise Mobility – Policies: View settings” Policy Configurations Query Global Administrator, administrator-defined roles with “McAfee Enterprise Mobility – Policies: View and change settings” Policy Configurations Modify, Delete Global Administrator, administrator-defined roles with “Mobile Actions: Allow Wipe Corporate Data” Wipe Corporate Data Execute Global Administrator, administrator-defined roles with “Mobile Actions: Allow Locking devices” Locking devices Execute Global Administrator, administrator-defined roles with “Mobile Actions: Allow Unlocking devices” Unlocking devices Execute Global Administrator, administrator-defined roles with “Mobile Actions: Allow uninstall” MDM Uninstall Execute 3 Global administrator is able to perform all operations. Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 39 of 40 AUTHORIZED ROLES3 TSF DATA OPERATION Global Administrator, administrator-defined roles with “Mobile Actions: Allow Wipe” EMM Portal user Wipe Execute Global Administrator, administrator-defined roles with “Use public dashboards” Compliance Reports Query Table 26 – Data Access Permissions ePO management permissions are defined per authorized administrator . Global Administrator status to an ePO account implicitly grants all permissions to that authorized administrator. Upon successful authentication the administrator permissions remain fixed for the duration of the session (until the administrator logs off). The TOE provides functionality to manage the following: 1. ePO User Accounts - Each authorized administrator for login to ePO must be defined with ePO (only administrative users are able to log in to ePO). Only Global Administrators may perform ePO user account management functions (create, view, modify and delete). 2. Permission Sets - A permission set is a group of permissions that can be granted to any authorized administrator by assigning it to those authorized administrators’ accounts. One or more permission sets can be assigned to any authorized administrator who are not Global Administrators (Global Administrators have all permissions to all products and features). Global Administrators may create, view, modify and delete permission sets. 3. Notifications - Notifications sent by ePO may be specified in response to events generated by the TOE. Notifications cause email messages to be sent to the configured recipient(s) or SNMP traps to be generated. 4. System tree - The system tree organizes managed systems in units for monitoring, assigning policies, scheduling tasks, and taking actions. The system tree is a hierarchical structure that allows systems to be organized within units called groups. 5. Queries - Authorized administrators may create, view, modify, use and delete queries based upon their permissions. 6. Dashboards - Authorized administrator-specific dashboards (including EMM compliance reports) may be configured to display data of interest to each administrator. These chart-based displays are updated at a configured rate to keep the information current. 7. EMM policies - EMM policies are configured on ePO. The policies determine what operations can be performed on each managed mobile device. 8. Mobile Actions – EMM actions to control access to mobile devices and protect corporate dates with targeted wipe functions can be initiated from ePO, and the wipe action can additionally be initiated from the Portal UI. Security Target: McAfee Enterprise Mobility Management 12.0 Document Version 1.16 © McAfee Page 40 of 40 9. Deployment of policies - Policies can be deployed from ePO to a managed mobile device, including the ability to wipe and lock a device. 7.4 Audit The TOE maintains an audit log for ePO-based actions. The auditable events are specified in the Audit Events and Details table in the FAU_GEN.1 section. Fields available include:  Action — The name of the action the McAfee EMM authorized administrator attempted.  Completion Time — The time the action finished.  Details — More information about the action.  Priority — Importance of the action.  Start Time — The time the action was initiated.  Success — Whether the action was successfully completed.  User Name —Name of the logged-on administrator account that was used to take the action.
