8 Architectural Information

The TOE is composed of software only running on purpose built hardware, both of which are developed by EMC Corporation.

The CLARiiON^® FLARE/Navisphere software runs on the EMC CLARiiON^® CX3 UltraScale Series of products. The product series consists of a variety of purpose-built appliances providing fault-tolerant storage with no single points of failure. They provide data replication capabilities, with open systems support and connectivity options, including Fibre Channel.

The TOE uses Fibre Channel to connect with application servers. Fibre Channel is a serial data transfer protocol that operates over copper wire or optical fiber. Networking and input/output protocols can be mapped to Fibre Channel constructs, and then encapsulated and transported within Fibre Channel frames. Fibre Channel technology is used in the implementation of storage area networks, or SANs. A SAN is a network linking servers and workstations to disk arrays, tape backup systems, and other storage devices, typically using Fibre Channel Protocol (FCP). The Fibre Channel SAN allows the application servers to issue input/output (I/O) requests to the TOE, which satisfies those requests using the storage areas assigned to the requesting server.

A Storage Processor (SP) has multiple Fibre Channel front-end ports implementing SCSI drivers for connecting to a SAN switch or for a direct connection to a server. Back-end Fibre Channel ports provide connections for a second SP and storage capacity expansion. The appliance also has two Ethernet local area network (LAN) ports. One port is used to access and manage the storage system via Navisphere. The other is a dedicated port for EMC Customer Service use when onsite.

Navisphere is a storage-system management application for configuring, monitoring, and managing CLARiiON^® storage systems. It resides on each storage system SP and is downloaded to the browser when the Storage Management Server software is accessed. Navisphere provides the following basic functionality:

• Discovery and monitoring of CLARiiON storage systems;
• Storage configuration and allocation;
• Status and configuration information display; and
• Event management.

Navisphere can be used to manage a single storage system or a storage domain (a group of storage systems connected by a network). The Storage Management Server software is provided with Navisphere and executes on each SP in a storage system, and performs the following functions:

• Receives and responds to requests from Navisphere Manager;
• Forwards status and configuration updates to Navisphere Manager;
• Replicates user and domain information to all storage systems in the storage domain;
• Authenticates and authorizes users; and
• Logs all user logins and requests.

Navisphere Manager is a web-based Graphical User Interface (GUI) to the Navisphere^® application that provides for the secure management of CLARiiON^® storage systems from the local network or remotely (over the Internet, using a common browser). Many of the management functions can also be accomplished using the Navisphere^® Secure Command Line Interface (CLI), a set of commands that can be executed in non-graphical environments. Access to these management interfaces is controlled by an authentication function that allows for user accounts defined within Navisphere.

The evaluators examined the developer's vulnerability analysis for the CLARiiON^® FLARE v3.24 with Navisphere v6.24 and found that it sufficiently described each of the potential vulnerabilities along with a sound rationale as to why it was not exploitable in the intended environment. Additionally, the evaluators conducted an independent review of public domain vulnerability databases, and all evaluation deliverables to provide assurance that the developer has considered all potential vulnerabilities.

All these evaluation activities resulted in PASS verdicts.

12 ITS Product Testing

Testing at EAL 2 consists of the following three steps: assessing developer tests, performing independent functional tests, and performing penetration tests.

12.1 Assessing Developer Tests

The evaluators verified that the developer had met their testing responsibilities by examining their test evidence, and reviewing their test results, as documented in the ETR ².

The evaluators analyzed the developer's test coverage analysis and found it to be complete and accurate. The correspondence between the tests identified in the developer's test documentation and the functional specification was complete.

12.2 Independent Functional Testing

During this evaluation, the evaluator developed independent functional tests by examining design and guidance documentation, examining the developer's test documentation, executing a sample of the developer's test cases, and creating test cases that augmented the developer tests.

All testing was planned and documented to a sufficient level of detail to allow repeatability of the testing procedures and results. Testing focused on:

• Identification and authentication;
• Security Management; and
• Basic product functionality.

12.3 Independent Penetration Testing

Subsequent to the examination of the developer's vulnerability analysis and the independent review of public domain vulnerability databases and all evaluation deliverables, limited independent evaluator penetration testing was conducted. The penetration tests focused on:

• Generic vulnerabilities;
• Bypassing;
• Tampering; and
• Direct attacks.

The independent penetration testing did not uncover any exploitable vulnerabilities in the anticipated operating environment.
