The evaluation was conducted using the Common Methodology for Information Technology Security Evaluation, Version 2.2 r256, for conformance to the Common Criteria for Information Technology Security Evaluation, version 2.2 r256, incorporating all final interpretations issued prior to 7 October 2004.

The nCircle^™ IP360^™ Vulnerability Management System V6.3.4 is:

1. Common Criteria Part 2 conformant, with security functional requirements based only upon functional components in Part 2; and
2. Common Criteria Part 3 conformant, with security assurance requirements based only upon assurance components in Part 3.

6 Security Policy

Security Management

The administrator and restricted user (when given permission by the administrator) are provided with a Graphic User Interface (GUI) to perform configuration and troubleshooting tasks. Restricted users are assigned privileges as determined by the administrator as per the security policy defined in the ST (Restricted User SFP (RU_SFP)). Alternatively, the VnE CLI (Command Line Interface) administrator and the DP/nTellect^™ CLI administrator can perform configuration tasks using the CLI Interface. The TOE maintains four roles, which can be further specified based on very granular privilege controls in the VnE: administrator, restricted user, VnE CLI admin, and DP/nTellect^™ CLI admin.

7 Assumptions and Clarification of Scope

Consumers of the nCircle^™ IP360^™ Vulnerability Management System V6.3.4 should consider assumptions about usage and environmental settings as requirements for the product's installation and its operating environment. This will help to ensure the proper and secure operation of the product.

7.1 Secure Usage Assumptions

The secure usage assumptions and security aspects of the environment in which the TOE will be used and the manner in which the TOE is expected to be employed are addressed in the Security Target. It is assumed that the product will be installed and configured using the guidance documents provided by nCircle^™ Network Security, Inc. The security procedures that the consumer must carry out to configure the system such that the TOE is setup in the CC mode of operation are documented in the guidance documents (listed in Section 10).

7.2 Environmental Assumptions

The TOE hardware and software critical to security policy enforcement are assumed to be within controlled access facilities that will prevent unauthorized physical access and modification by potentially hostile outsiders. The administrator is responsible for ensuring that the assumptions and all the environmental objectives listed in Section 3 and Section 4 of the Security Target document are met in the deployed environment.

Some of the TOE self-protection (e.g., against physical tampering) is ensured by its environment. In particular, it is assumed that the TOE will remain attached to the physical connections made by a TOE user so that the TOE cannot be bypassed. Each IP360^™ appliance is completely self-contained in that the hardware, operating system and applications provide all the services necessary to implement the TOE.

7.3 Clarification of Scope

The nCircle^™ IP360^™ Vulnerability Management System V6.3.4 can not prevent authorized administrators from carelessly configuring the system such that the TOE is not setup in CC mode of operation.

8 Architectural Information

The TOE comprises of the following functional components:

1. Graphical User Interface (GUI) – the VnE GUI encapsulates the functionality to manage the TOE. The GUI is accessible via a web browser with TLS enabled.
2. Device Profiler – performs network scanning at the request of the VnE. The profiling functionality is not a TSP enforcing component of the TOE.
3. nTellect^™ - analyzes information from specific IP enabled devices on the target network. The analysis functionality is not a TSP enforcing component of the TOE.
4. Command Line Interface (CLI) – a command line interface exists for each device that encapsulates the functionality of configuring said device.
5. Events – the events component of the VnE is responsible for generating alerts and handling events such as trouble state reporting.
6. Reporting – the reporting component of the VnE is responsible for generating reports on scan results.
7. Upgrade - encapsulates the functionality of downloading upgrades from the software repository, and processing and installing the downloaded packages.

12 ITS Product Testing

Testing at EAL 3 consists of the following three steps: assessing developer tests, performing independent functional tests, and performing independent vulnerability tests. During this evaluation, the evaluators developed their independent tests by examining the design and guidance documentation, examining developer analysis, and repeating a sub-set of developer tests.

12.1 Assessing Developer Tests

The evaluators verified that the developer met their testing responsibilities by examining their test evidence, reviewing their test results, witnessing a subset of testing on site and repeating a subset of the developer tests.

The evaluators reviewed the developer's analysis of test coverage and depth and found them to be complete and accurate. The correspondence between the tests identified in the developer's test documentation and the functional specification and high-level design (HLD) was complete.

The subset of the developer tests that were repeated was selected based on the following:

1. TOE Summary Specification (TSS) coverage;
2. Security Functional Requirement (SFR) coverage;
3. HLD sub-system coverage;
4. Tests of interest; and
5. Random selection.

Developer's test cases were witnessed/repeated during the site visit and tests were repeated by the evaluator during independent testing.

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.

12.3 Independent Penetration Testing

The evaluators devised a set of penetration tests based on the developer's vulnerability analysis. Vulnerabilities assessed as potentially exploitable by an attacker possessing a low attack potential were used to develop penetration test cases.

The following potential attack areas were assessed during the development of potential attack scenarios:

1. Generic vulnerabilities;
2. Bypassing;
3. Tampering;
4. Direct attacks; and
5. Misuse.

At least one penetration attack and in most cases multiple attacks were developed for each of these areas. A total of 16 penetration attacks were developed and exercised against the TOE.
