ARCHITECTURAL INFORMATION Note: The following architectural description is based on the description presented in the Security Target. 3.1.TOE Description The TOE consists of the FireEye MX series appliances. These products provide real-time visibility of threats on mobile devices, displays play-by-play analysis of suspicious apps, provides an index of pre-analyzed apps, and generates threat assessments for custom apps. FireEye MX Series Appliances (MX 900, MX 8400) The FireEye® MX series are mobile management platforms that work in conjunction with the FireEye MTP App to assimilate and disperse threat information to mobile endpoints, and offer integration with MDM solutions for a true detect to fix solution. TOE Evaluated Configuration The TOE evaluated configuration consists of the MX 900 or MX 8400 appliance listed above. The TOE also supports (sometimes optionally) secure connectivity with several other IT environment devices. The following figure provides a visual depiction of an example TOE deployment. The TOE boundary is surrounded with a hashed red line. TOE Example Deployment FireEye MX Series Appliances Validation Report, Version 1.0 January 21, 2016 7 3.2.PHYSICAL SCOPE OF THE TOE The TOE is a hardware and software solution that makes up the appliances as described above. The TOE guidance documentation is considered to be part of the TOE. 3.3.LOGICAL SCOPE OF THE TOE The TOE is comprised of several security features. Each of the security features identified above consists of several security functionalities, as identified below. 1. Security Audit 2. Cryptography Support 3. User Data Protection 4. Identification & Authentication 5. Security Management 6. Protection of the TSF 7. Trusted Path/Channel 8. TOE Access 3.3.1. Security Audit The FireEye MX Series Appliances provide extensive auditing capabilities. The TOE generates a comprehensive set of audit logs that identify specific TOE operations. For each event, the TOE records the date and time of each event, the type of event, the subject identity, and the outcome of the event. Auditable events include: failure on invoking cryptographic functionality such as establishment, termination and failure of a TLS session; establishment, termination and failure of an SSH session; modifications to the group of users that are part of the authorized administrator roles; all use of the user identification mechanism; any use of the authentication mechanism; any change in the configuration of the TOE, changes to time, initiation of TOE update, indication of completion of TSF self-test, maximum sessions being exceeded, termination of a remote session; and initiation and termination of a trusted channel. The TOE is configured to transmit its audit messages to an external syslog server. Communication with the syslog server is protected using TLS and the TOE can determine when communication with the syslog server fails. The logs for all of the appliances can be viewed on the TOE via the TOE CLI. The records include the date/time the event occurred, the event/type of event, the user ID associated with the event, and additional information of the event and its success and/or failure. The TOE does not have an interface to modify audit records, though there is an interface available for the authorized administrator to clear audit data stored locally on the TOE. 3.3.2. Cryptographic Support FireEye MX Series Appliances Validation Report, Version 1.0 January 21, 2016 8 The TOE provides cryptographic support for the following features,  TLS connectivity with the following entities: o Audit Server  SSH connectivity with the following entities: o Management SSH Client  Secure software update 3.3.3. User Data Protection The TOE ensures that all information flows from the TOE do not contain residual information from previous traffic. Packets are padded with zeros. Residual data is never transmitted from the TOE. 3.3.4. Identification & Authentication The TOE performs two types of authentication: device-level authentication of remote IT Environment devices (e.g., audit servers) and user authentication for the Authorized Administrator of the TOE. Device-level authentication of remote IT Environment devices allows the TOE to establish a secure channel with an IT Environment trusted peer. The secure channel is established only after each device authenticates the other. This device-level authentication is performed via TLS authentication. The TOE provides authentication services for administrative users to connect to the TOEs secure CLI administrator interface. The TOE requires Authorized Administrators to authenticate prior to being granted access to any of the management functionality. In the Common Criteria evaluated configuration, the TOE is configured to require a minimum password length of 15 characters, as well as, mandatory password complexity rules. The TOE provides administrator authentication against a local user database. Password-based authentication can be performed on any TOE administrative interface including local CLI and remote CLI over SSH. 3.3.5. Security Management The TOE provides secure administrative services for management of general TOE configuration and the security functionality provided by the TOE. Management can take place over two interfaces including:  Local console command line administration at each of the appliances  Remote command line administration via SSHv2 at each of the appliances The TOE provides the ability to securely manage: FireEye MX Series Appliances Validation Report, Version 1.0 January 21, 2016 9  All TOE administrative users;  All identification and authentication;  All audit functionality of the TOE;  All TOE cryptographic functionality;  The timestamps maintained by the TOE; and  Update to the TOE. The TOE supports several administrator roles, including,  Admin: The system administrator is a “super user” who has all capabilities.  Monitor: The system monitor has read-only access  Operator: The system operator has a subset of the capabilities associated with the admin role.  Analyst: The system analyst focuses on data plane analysis.  Auditor: The system auditor reviews audit logs and performs forensic analysis. These roles are collectively known as the “Authorized Administrator” The TOE supports the configuration of login banners to be displayed at time of login and inactivity timeouts to terminate administrative sessions after a set period of inactivity. 3.3.6. Protection of the TSF The TOE protects against interference and tampering by untrusted subjects by implementing identification, authentication, and access controls to limit configuration to Authorized Administrators. The TOE prevents reading of cryptographic keys and passwords. Additionally the TOE software is a custom-built hardened version of Linux and access to memory space is restricted to only require software services. The TOE internally maintains the date and time. This date and time is used as the timestamp that is applied to audit records generated by the TOE. Administrators can update the TOE’s clock manually, or can configure the TOE to use NTP to synchronize the TOE’s clock with an external time source. Finally, the TOE performs testing to verify correct operation of the security appliances themselves. The TOE verifies all software updates via digital signature and requires administrative intervention prior to the software updates being installed on the TOE to avoid the installation of unauthorized software. FireEye MX Series Appliances Validation Report, Version 1.0 January 21, 2016 10 3.3.7. TOE Access The TOE can terminate inactive sessions after an Authorized Administrator configurable time- period. Once a session has been terminated the TOE requires the user to re-authenticate to establish a new session. The TOE also displays an Authorized Administrator configured banner on the CLI management interface prior to allowing any administrative access to the TOE. 3.3.8. Trusted Path/Channel The TOE supports several types of secure communications, including,  Trusted paths with remote administrators over SSH,  Trusted channels with remote IT Environment audit servers over TLS, Each of these trusted paths/channels are secured using either TLS or SSH.
