The product Oracle Database 11g Release 2 Enterprise Edition has undergone the certification procedure at BSI. This is a re-certification based on BSI-DSZ-CC Specific results from the evaluation process BSI-DSZ-CC were re-used. The evaluation of the product Oracle Database 11g Release 2 Enterprise Edition 6 was conducted by atsec information security GmbH. The evaluation was completed on 7 December The atsec information security GmbH is an evaluation facility (ITSEF) 7 recognised by the certification body of BSI. For this certification procedure the developer, sponsor and applicant is: Oracle Corporation. The certification is concluded with the comparability check and the production of this Certification Report. This work was completed by the BSI. 4 Validity of the Certification Result This Certification Report only applies to the version of the product as indicated. The confirmed assurance package is only valid on the condition that 6 version , with all critical patch updates up to and including July 2011 via the July 2011 PSU as well as the October 2011 CPU 7 Information Technology Security Evaluation Facility 10 / 38
11 BSI-DSZ-CC Certification Report all stipulations regarding generation, configuration and operation, as given in the following report, are observed, the product is operated in the environment described, where specified in the following report and in the Security Target. For the meaning of the assurance levels please refer to the excerpts from the criteria at the end of the Certification Report. The Certificate issued confirms the assurance of the product claimed in the Security Target at the date of certification. As attack methods evolve over time, the resistance of the certified version of the product against new attack methods needs to be re-assessed. Therefore, the sponsor should apply for the certified product being monitored within the assurance continuity program of the BSI Certification Scheme (e.g. by a re-certification). Specifically, if results of the certification are used in subsequent evaluation and certification procedures, in a system integration process or if a user's risk management needs regularly updated results, it is recommended to perform a re-assessment on a regular e.g. annual basis. In case of changes to the certified version of the product, the validity can be extended to the new versions and releases, provided the sponsor applies for assurance continuity (i.e. re-certification or maintenance) of the modified product, in accordance with the procedural requirements, and the evaluation does not reveal any security deficiencies. 5 Publication The product Oracle Database 11g Release 2 Enterprise Edition has been included in the BSI list of the certified products, which is published regularly (see also Internet: and [5]).

14 Certification Report BSI-DSZ-CC Executive Summary The Target of Evaluation (TOE) is the software application Oracle Database 11g Release 2 Enterprise Edition. Oracle Database 11g is an object-relational database management system (ORDBMS), providing advanced security functionality for multi-user distributed database environments. The security functionality in Oracle Database 11g includes: user identification and authentication, with password management options and support for enterprise users (password option only). In the case of Enterprise Users this function is partly provided by the IT-environment. discretionary access controls on database objects, which controls access to objects based on the identity of the subjects or groups to which the subjects and objects belong, and which allows authorized users to specify how the objects that they control are protected; granular privileges for the enforcement of least privilege; user-configurable roles for privilege management, including an authorized administration role to allow authorized administrators to configure the policies for discretionary access control, identification and authentication, and auditing. quotas on the amount of processing resources a user can consume during a database session; audit capture is the function that creates information on all auditable events; extensive and flexible auditing options; secure access to remote Oracle databases; and stored procedures, triggers and security policies for user-defined access controls and auditing. The Enterprise Edition of Oracle Database 11g has no limitations on the number of CPUs or the number of users, and supports databases up to a size of 8 Exabyte. The Enterprise Edition is targeted at large to very large organizations with a high volume of transactions. The Security Target [6] is the basis for this certification. It is based on the certified Protection Profile U.S. Government Protection Profile for Database Management Systems, Version 1.3, 24 December 2010 [7]. The TOE Security Assurance Requirements (SAR) are based entirely on the assurance components defined in Part 3 of the Common Criteria (see part C or [1], Part 3 for details). The TOE meets the assurance requirements of the Evaluation Assurance Level EAL 4 augmented by ALC_FLR.3. The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the Security Target [6], chapter 5. They are selected from Common Criteria Part 2 and some of them are newly defined. Thus the TOE is CC Part 2 extended. The TOE Security Functional Requirements are implemented by the following TOE Security Functionalities: 14 / 38

The assets to be protected by the TOE are defined in the Security Target [6], chapter 3 and the Protection Profile [7]. Based on these assets the TOE Security Problem is defined in terms of Assumptions, Threats and Organisational Security Policies. This is outlined in the Security Target [6], chapter 3. The TOE configuration that was covered by this certification is defined by the ST and further detailed by the guidance documentation a user has to follow. For further details on this topic please refer to chapter 8 of this report. The vulnerability assessment results as stated within this certificate do not include a rating for those cryptographic algorithms and their implementation suitable for encryption and decryption (see BSIG Section 9, Para. 4, Clause 2). The certification results only apply to the version of the product indicated in the certificate and on the condition that all the stipulations are kept as detailed in this Certification Report. This certificate is not an endorsement of the IT product by the Federal Office for Information Security (BSI) or any other organisation that recognises or gives effect to this certificate, and no warranty of the IT product by BSI or any other organisation that recognises or gives effect to this certificate, is either expressed or implied. 2 Identification of the TOE The Target of Evaluation (TOE) is called: Oracle Database 11g Release 2 Enterprise Edition The following table outlines the TOE deliverables: No Type Identifier Release Form of Delivery 1 SW Oracle Database 11g Release 2 ( ) Media Pack for Linux x SW Patch : PATCH SET FOR ORACLE DATABASE SERVER 3 SW Patch : DATABASE PSU (INCLUDES CPUJUL2011) electronic or physical media electronic electronic 4 SW Patch : CPUOCT2011 DATABASE electronic 5 DOC Oracle Database 11g Release 2 (11.2) Documentation 11.2 electronic 6 DOC Evaluated Configuration for Oracle Database 11g Release 2 ( ) electronic 15 / 38
16 Certification Report BSI-DSZ-CC No Type Identifier Release Form of Delivery 7 DOC Common Criteria Oracle Database 11gR2 ( ) Enterprise Edition, Standard Edition and Standard Edition 1 Support Note Table 2: Deliverables of the TOE electronic The scope of delivery mechanisms covered by this evaluation includes the delivery of the base TOE via both physical media and electronic download, and the delivery of patches via electronic download. Guidance documents can be obtained from Oracle by Physical media (cf. table 2, no. 1) Consumers can check the media shipped by Oracle to them for signs of tampering and authenticity by inspecting the following aspects: Oracle graphics and logo are on packaging material and boxes The box is taped closed, and CD envelopes are sealed. The box containing the CDs is not sealed, but the order box as a whole is sealed Associated with each order there will be an invoice number that will be assigned by Oracle and made known to the customer. Each order is traceable at any given point in time via the tracking number that is assigned by the carrier. The consumer has a reference number, which is distinct to the invoice number and the tracking number. The packing slip with the address of sender and recipient contains the order details and information listed above. Each order is delivered by a trusted carrier, and the number of boxes will be clearly marked. 2. Electronic delivery of the base TOE For electronic delivery of the TOE, deliverable No. 6 provides instructions for verifying SHA-1 hash sums provided for the software to the consumer. These hash sums are provided on the software download page, along with a link to the actual file to be downloaded. After the user has downloaded the TOE, the user can generate the hash values for the TOE using the same algorithm used by the developer, and then compare this value to the published value. If any change has been applied to the file since the developer computed the hash, the hashed value for the received file is different from the hashed value for the original file, and so comparison of the values reveals that modification has occurred. On the other hand, if the two hash values match, this indicates that the data has not been altered and therefore ensures the integrity of the downloaded software images. In order to trust the hash sums and the downloaded images, trust in the web server needs to be established. The server edelivery.oracle.com can be reached using SSL-protected HTTP (HTTPS). As the hash sums can be downloaded using the SSL-protected HTTP mechanism, authenticity of these hash sums can be ensured. Therefore, by using these hash sums, the authenticity of the ISO images can be verified. 16 / 38
17 BSI-DSZ-CC Certification Report Deliverable No. 6 contains step-by-step instructions for consumers on how to perform the validation tasks. 3. Electronic delivery of patches that are part of the TOE The same mechanisms that apply to download of the base TOE apply to the download of patches. Checksums are available as well via Metalink (now known as My Oracle Support, or support.oracle.com), an SSL-protected web portal. 4. Guidance delivery The exact version of the guidance documents that were subject to evaluation as part of this TOE can be requested from the developer by ing The authenticity can then further be verified by validating hash sums, as described for the electronic delivery of the software parts above: Oracle provides a Support Note on the My Oracle Support website (the same website used to download product patches, see above) that contains the hash sums for all guidance documents that are part of the TOE. The procedure for obtaining and validating guidance documents is thus: Obtain the evaluated version of documents from Oracle by Download the Support Note with the title "Common Criteria Oracle Database11gR2 ( ) Enterprise Edition, Standard Edition and Standard Edition 1 Support Note" from the My Oracle Support website, and validate the SHA-1 hash sum for the support note as described above for electronic delivery of the software Validate the hash sums for individual guidance documents by comparing the hash sums provided in the Support Note and generating SHA-1 hashes over the documents provided by Oracle 3 Security Policy The Security Policy is expressed by the set of Security Functional Requirements and implemented by the TOE. It covers the following issues: Discretionary Access Control Policy Quota Policy Identification and Authentication Policy Auditing Policy Security Management Policy Consistency of replicated TSF Data Policy For details on the SFRs used to implement those policies please refer to the Security Target [6], chapter 5. 4 Assumptions and Clarification of Scope The Assumptions defined in the Security Target and some aspects of Threats and organisational Security Policies are not covered by the TOE itself. These aspects lead to specific security objectives to be fulfilled by the TOE-Environment. The following topics are of relevance: OE.DIR_CONTROL, OE.COM_PROT and OE.CLIENT_AP. Details can be 17 / 38
18 Certification Report BSI-DSZ-CC found in the Security Target [6], chapter 4 or in the Protection Profile the ST is claiming conformance to [7]. 5 Architectural Information An Oracle database contains the data dictionary and two different types of database objects: schema objects that belong to a specific user schema and contain user-defined information; and non-schema objects to organise, monitor, and control the database. In an Oracle database there are two types of connections for users of the database: Administrator connection. This covers users who connect to the database via AS SYSOPER or AS SYSDBA by virtue of possessing either the SYSOPER or SYSDBA system privilege. Users making a connection AS SYSOPER are allowed to perform operator administrative tasks (e.g. database startup and shutdown, and ALTER DATABASE commands). Users making a connection AS SYSDBA are allowed to perform all administrative tasks (including granting and/or revoking object privileges on other users objects); Normal connection (note that this includes users SYS and SYSTEM. This covers users who are authorised to access the database by virtue of being explicitly defined and identified to an instance of the Oracle database server. 5.1 Data Dictionary and Database At the center of an Oracle database is the data dictionary - a set of internal Oracle tables that contain all of the information the Oracle database server needs to manage the database. The data dictionary tables are owned by the user SYS and can only be modified by highly privileged users. A set of read-only views is provided to display the contents of the internal tables in a meaningful way and also allow Oracle users to query the data dictionary without the need to access it directly. All of the information about database objects is stored in the data dictionary and is updated by the SQL DDL commands that create, alter, and drop database objects. Other SQL commands also insert, update, and delete information in the data dictionary in the course of their processing. Technically, a set of server processes (a so-called instance) operates on a database, i.e., the files which contain the data. Users employ interface products to establish database connections with a database instance, and to query the database using the Structured Query Language (SQL)and Oracle-specific extensions of it. 5.2 Distributed Databases In a distributed environment, a user may access database objects from multiple databases. After establishing an initial database session on one instance, the user can transparently establish database sessions on other (remote) database instances using database links. A database link identifies a remote database and provides authentication information. By qualifying references to database objects with the name of a database link, a user can access remote database objects. 18 / 38
19 BSI-DSZ-CC Certification Report 5.3 Enterprise Users The TOE supports Enterprise Users. If configured, users are authenticated against a centrally managed directory in the TOE environment, rather than against the TOE's local database. 5.4 Partitioning The TOE supports Partitioning, which addresses key issues in supporting very large tables and indexes by letting you decompose them into smaller and more manageable pieces called partitions. SQL queries and DML statements do not need to be modified in order to access partitioned tables. However, after partitions are defined, DDL statements can access and manipulate individual partitions rather than entire tables or indexes. 5.5 Real Application Clusters Real Application Clusters (RAC) comprises several Oracle instances running on multiple clustered computers, which communicate with each other by means of a so-called interconnect. RAC uses cluster software to access a shared database that resides on shared disk. RAC combines the processing power of these multiple interconnected computers to provide system redundancy,near linear scalability, and high availability. 6 Documentation The evaluated documentation as outlined in table 2 is being provided with the product to the customer. This documentation contains the required information for secure usage of the TOE in accordance with the Security Target. Additional obligations and notes for secure usage of the TOE as outlined in chapter 10 of this report have to be followed. 7 IT Product Testing 7.1 Test Configuration The TOE was tested in its evaluated configuration on the following platforms: Red Hat Enterprise Linux 5.5 Advanced Platform SuSE Linux Enterprise Server 11 Oracle Enterprise Linux Version 5 Update Developer Testing Developer testing provided coverage for all TSF's and all TSF related subsystems. The evaluator was satisfied with the results witnessed for both the automated tests and manual tests and confirmed all tests passed successfully. 7.3 Evaluator Testing Effort The evaluator followed a threefold, non-symmetric approach to test the TOE. The following test configurations were used: 19 / 38
20 Certification Report BSI-DSZ-CC The evaluator test environment set up in Munich. The evaluator's test environment setup in the Munich lab consisted of a OEL, RHEL and SLES installation of the TOE in a Non-RAC configuration. For the (re-) run of the selected set of vendor tests: These tests were run (and observed) during a visit in Reading, The evaluator witnessed a controlled run of the vendor's test scripts. A RAC cluster running on Linux has been set up by the evaluator at the developer's site in Reading, UK. The evaluator used this configuration to directly assess the provided installation guidance for RAC clusters as well as to perform some RAC related tests. In summary, the evaluator successfully covered all of the TOE Security Functions by either evaluator defined tests or a re-run of a selected set of vendor tests. The evaluators conclude that sufficient functional testing has been achieved on the TOE to give the appropriate level of assurance that the TOE software has no security functionality flaws when running on Red Hat Enterprise Linux AS Version 5 update 5, Oracle Enterprise Linux Version 5 Update 5 and SuSE Linux Enterprise Server 11 operating systems. 7.4 Evaluator Penetration Testing The evaluator used the information on potential vulnerabilities collected by the evaluators during the evaluation that should be considered in the vulnerability analysis. In addition, the evaluator took into account the ST, guidance documentation, functional specification, TOE design, security architecture description and implementation representation to identify possible potential vulnerabilities. As result of these activities, the evaluator defined a penetration test framework and produced penetration tests to verify the vulnerabilities. None of the penetration test were successful. The evaluator used a commercial scanner to scan the TOE for known vulnerabilities. No applicable vulnerabilities were detected. The penetration was carried out using the source code, the external interfaces of the TOE, namely the OCI interface stack as well as the "sqlplus" command interface. The subsystems subject to penetration testing are all parts of the TOE. In summary, no exploitable vulnerabilities were identified. 8 Evaluated Configuration The TOE subject of this report is Oracle Database 11g Release 2 Enterprise Edition. The conditions set by the documents [6] (the Security Target) and [9] (the evaluated configuration guide) have to be met in order to result in an evaluated configuration of the TOE. 20 / 38
21 BSI-DSZ-CC Certification Report 9 Results of the Evaluation 9.1 CC specific results The Evaluation Technical Report (ETR) [8] was provided by the ITSEF according to the Common Criteria [1], the Methodology [2], the requirements of the Scheme [3] and all interpretations and guidelines of the Scheme (AIS) [4] as relevant for the TOE. The Evaluation Methodology CEM [2] was used. As a result of the evaluation the verdict PASS is confirmed for the following assurance components: All components of the EAL 4 package including the class ASE as defined in the CC (see also part C of this report) The components ALC_FLR.3 augmented for this TOE evaluation. As the evaluation work performed for this certification procedure was carried out as a reevaluation based on the certificate BSI-DSZ-CC , re-use of specific evaluation tasks was possible. The focus of this re-evaluation was on on the integration of new and modified features from the previously evaluated version of the Oracle database. The evaluation has confirmed: PP Conformance: U.S. Government Protection Profile for Database Management Systems, Version 1.3, 24 December 2010 [7] for the Functionality: PP conformant plus product specific extensions Common Criteria Part 2 extended for the Assurance: Common Criteria Part 3 conformant EAL 4 augmented by ALC_FLR.3 For specific evaluation results regarding the development and production environment see annex B in part D of this report. The results of the evaluation are only applicable to the TOE as defined in chapter 2 and the configuration as outlined in chapter 8 above. 9.2 Results of cryptographic assessment The TOE does not include cryptoalgorithms. Thus, no such mechanisms were part of the assessment. 10 Obligations and Notes for the Usage of the TOE The documents as outlined in table 2 contain necessary information about the usage of the TOE and all security hints therein have to be considered. In addition all aspects of Assumptions, threats and policies as outlined in the Security Target not covered by the TOE itself need to be fulfilled by the operational environment of the TOE. The customer or user of the product shall consider the results of the certification within his system risk management process. In order for the evolution of attack methods and techniques to be covered, he should define the period of time until a re-assessment for the TOE is required and thus requested from the sponsor of the certificate. If available, certified updates of the TOE should be used. If non-certified updates or patches are available the user of the TOE should request the sponsor to provide a re- 21 / 38
22 Certification Report BSI-DSZ-CC certification. In the meantime a risk management process of the system using the TOE should investigate and decide on the usage of not yet certified updates and patches or take additional measures in order to maintain system security. 11 Security Target For the purpose of publishing, the Security Target [6] of the Target of Evaluation (TOE) is provided within a separate document as Annex A of this report. 12 Definitions 12.1 Acronyms AIS BSI BSIG CCRA CC CEM EAL ETR IT ITSEC ITSEF PP SAR SFP SFR ST TOE TSF 12.2 Glossary Application Notes and Interpretations of the Scheme Bundesamt für Sicherheit in der Informationstechnik / Federal Office for Information Security, Bonn, Germany BSI-Gesetz / Act on the Federal Office for Information Security Common Criteria Recognition Arrangement Common Criteria for IT Security Evaluation Common Methodology for Information Technology Security Evaluation Evaluation Assurance Level Evaluation Technical Report Information Technology Information Technology Security Evaluation Criteria Information Technology Security Evaluation Facility Protection Profile Security Assurance Requirement Security Function Policy Security Functional Requirement Security Target Target of Evaluation TOE Security Functionalities Augmentation - The addition of one or more requirement(s) to a package.

25 BSI-DSZ-CC Certification Report C Excerpts from the Criteria CC Part1: Conformance Claim (chapter 10.4) The conformance claim indicates the source of the collection of requirements that is met by a PP or ST that passes its evaluation. This conformance claim contains a CC conformance claim that: describes the version of the CC to which the PP or ST claims conformance. describes the conformance to CC Part 2 (security functional requirements) as either: CC Part 2 conformant - A PP or ST is CC Part 2 conformant if all SFRs in that PP or ST are based only upon functional components in CC Part 2, or CC Part 2 extended - A PP or ST is CC Part 2 extended if at least one SFR in that PP or ST is not based upon functional components in CC Part 2. describes the conformance to CC Part 3 (security assurance requirements) as either: CC Part 3 conformant - A PP or ST is CC Part 3 conformant if all SARs in that PP or ST are based only upon assurance components in CC Part 3, or CC Part 3 extended - A PP or ST is CC Part 3 extended if at least one SAR in that PP or ST is not based upon assurance components in CC Part 3. Additionally, the conformance claim may include a statement made with respect to packages, in which case it consists of one of the following: Package name Conformant - A PP or ST is conformant to a pre-defined package (e.g. EAL) if: the SFRs of that PP or ST are identical to the SFRs in the package, or the SARs of that PP or ST are identical to the SARs in the package. Package name Augmented - A PP or ST is an augmentation of a predefined package if: the SFRs of that PP or ST contain all SFRs in the package, but have at least one additional SFR or one SFR that is hierarchically higher than an SFR in the package. the SARs of that PP or ST contain all SARs in the package, but have at least one additional SAR or one SAR that is hierarchically higher than an SAR in the package. Note that when a TOE is successfully evaluated to a given ST, any conformance claims of the ST also hold for the TOE. A TOE can therefore also be e.g. CC Part 2 conformant. Finally, the conformance claim may also include two statements with respect to Protection Profiles: PP Conformant - A PP or TOE meets specific PP(s), which are listed as part of the conformance result. Conformance Statement (Only for PPs) - This statement describes the manner in which PPs or STs must conform to this PP: strict or demonstrable. For more information on this Conformance Statement, see Annex D. 25 / 38
31 BSI-DSZ-CC Certification Report Evaluation assurance level 1 (EAL1) - functionally tested (chapter 8.3) Objectives EAL1 is applicable where some confidence in correct operation is required, but the threats to security are not viewed as serious. It will be of value where independent assurance is required to support the contention that due care has been exercised with respect to the protection of personal or similar information. EAL1 requires only a limited security target. It is sufficient to simply state the SFRs that the TOE must meet, rather than deriving them from threats, OSPs and assumptions through security objectives. EAL1 provides an evaluation of the TOE as made available to the customer, including independent testing against a specification, and an examination of the guidance documentation provided. It is intended that an EAL1 evaluation could be successfully conducted without assistance from the developer of the TOE, and for minimal outlay. An evaluation at this level should provide evidence that the TOE functions in a manner consistent with its documentation. Evaluation assurance level 2 (EAL2) - structurally tested (chapter 8.4) Objectives EAL2 requires the co-operation of the developer in terms of the delivery of design information and test results, but should not demand more effort on the part of the developer than is consistent with good commercial practise. As such it should not require a substantially increased investment of cost or time. EAL2 is therefore applicable in those circumstances where developers or users require a low to moderate level of independently assured security in the absence of ready availability of the complete development record. Such a situation may arise when securing legacy systems, or where access to the developer may be limited. Evaluation assurance level 3 (EAL3) - methodically tested and checked (chapter 8.5) Objectives EAL3 permits a conscientious developer to gain maximum assurance from positive security engineering at the design stage without substantial alteration of existing sound development practises. EAL3 is applicable in those circumstances where developers or users require a moderate level of independently assured security, and require a thorough investigation of the TOE and its development without substantial re-engineering. 31 / 38
