UNCLASSIFIED / NON CLASSIFIÉ//TLP:CLEAR
Assumptions and Clarification of Scope
Consumers of the TOE should consider assumptions about usage and environmental settings as
requirements for the product’s installation and its operating environment. This will ensure the proper
and secure operation of the TOE.
Usage and Environmental Assumptions
The following assumptions are made regarding the use and deployment of the TOE:
 The operational environment is assumed to provide the TOE with appropriate physical protection
such that the TOE is not subject to physical attack that may compromise the security and/or
interfere with the platform’s correct operation. This includes protection for the physical
infrastructure on which the TOE depends for correct operation and hardware devices on which the
TOE is executing.
 Authorized users possess the necessary authorization to access the information managed by the
TOE in accordance with organization information access policies.
 The TOE security functionality is managed by one or more competent, authorized administrators.
The system administrative personnel are not careless, willfully negligent, or hostile, and will follow
and abide by the instructions provided by the guidance documentation.
 Authorized users are sufficiently trained to accomplish a task or group of tasks within a secure IT
environment by exercising complete control over their user data.
 There are no general-purpose computing capabilities (e.g., compilers or user applications)
available on DBMS servers, other than those services necessary for the operation, administration,
and support of the DBMS.
 All external IT systems trusted by the TSF to provide TSF data or services to the TOE, or to support
the TSF in the enforcement of security policy decisions are assumed to correctly implement the
functionality used by the TSF consistent with the assumptions defined for this functionality and to
be properly managed and operate under security policy constraints compatible with those of the
TOE.
 Any information provided by a trusted entity in the IT environment and used to support the
provision of time and date, information used in audit capture, user authentication, and
authorization that is used by the TOE is correct and up to date.
9
UNCLASSIFIED / NON CLASSIFIÉ//TLP:CLEAR
 All connections to and from remote trusted IT systems and between separate parts of the TSF not
protected by the TSF itself are physically and/or logically protected within the TOE environment to
ensure the integrity and confidentiality of the data transmitted and to ensure the authenticity of
the communication end points.
Clarification of Scope
The TOE relies on the operating system, which is part of the operational environment, to provide
cryptographic support for communications, such as SSL encryption. Thus, cryptographic functionality
is outside the scope of this evaluation. Specifically, support for secure communication channels and
certificate-based authentication was not evaluated.
Crunchy PostgreSQL provides synchronous streaming replication as a way to replicate changes to
data on one database server to the other database servers within a cluster. The evaluated TOE
architecture is a stand-alone system running a single PostgreSQL server. Thus, streaming replication
functionality is outside the scope of this evaluation.
The following TOE configuration options are not included within the scope of the evaluation:
 “Trust” authentication option
 “Ident” authentication option
 “SSPI” authentication option
 Certificate authentication option
 GSSAPI Authentication
 Peer Authentication
 Streaming Replication Configuration
 Logical Replication Configuration

Evaluation Analysis Activities
The evaluation activities comprised a structured assessment of the TOE. Documentation and
processes related to Development, Guidance Documentation, and Life-Cycle Support were reviewed
and analyzed.
Development
The evaluators analyzed the documentation provided by the vendor; they determined that the design
completely and accurately describes the TOE security functionality (TSF) interfaces and how the TSF
implements the security functional requirements. The evaluators determined that the initialization
process is secure, that the security functions are protected against tamper and bypass, and that
security domains are maintained.
Guidance Documents
The evaluators examined the TOE preparative user guidance and operational user guidance and
determined that it sufficiently and unambiguously describes how to securely transform the TOE into
its evaluated configuration and how to use and administer the product. The evaluators exercised the
preparative and operational guidance and determined that they are complete and sufficiently detailed
to result in a secure configuration.
Life-Cycle Support
An analysis of the TOE configuration management system and associated documentation was
performed. The evaluators found that the TOE configuration items were clearly marked.
The evaluators examined the delivery documentation and determined that it described all the
procedures required to maintain the integrity of the TOE during distribution to the consumer.

UNCLASSIFIED / NON CLASSIFIÉ//TLP:CLEAR
Testing Activities
Testing consists of the following three steps: assessing developer tests, performing independent
tests, and performing a vulnerability analysis.
Assessment of Developer Tests
The evaluators verified that the developer has met their testing responsibilities by examining their
test evidence, and reviewing their test results, as documented in the Evaluation Test Report (ETR).
The correspondence between the tests identified in the developer’s test documentation and the
functional specification was complete.
Conduct of Testing
The TOE was subjected to a comprehensive suite of formally documented, independent functional
and penetration tests. The detailed testing activities, including configurations, procedures, test cases,
expected results and observed results are documented in a separate proprietary test results
document.
Independent Testing
During this evaluation, the evaluator developed independent functional & penetration tests by
examining design and guidance documentation.
All testing was planned and documented to a sufficient level of detail to allow repeatability of the
testing procedures and results. The following testing activities were performed:
a. PP Assurance Activities: The evaluator performed the assurance activities listed in the
claimed PP;
b. Repeat of Developer's Tests: The evaluator repeated a subset of the developer's tests; and
c. Cryptographic implementation verification: The evaluator verified that the claimed
cryptographic implementation was present in the TOE.
Independent Testing Results
The testing produced the expected results, supporting the conclusion that the TOE correctly
implements the functional requirements specified in the ST and the TOE functional specification.
