Security TargetVersion 1.1, March 30, 20121. Security Target IntroductionThis section identifies the Security Target (ST) and Target of Evaluation (TOE) identification, ST conventions, STconformance claims, and the ST organization.The TOE is an Intrusion Detection System (IDS) consisting of several components that coordinate with one anotherto collect and analyze information from multiple log sources (such as Windows events, syslog, flat file, NetFlow,sFlow, databases or applications) and provides tools to view and analyze IDS results and to issue alerts of significantevents.The product can also provide endpoint monitoring and control functionality, but these capabilities are not addressedby the IDS System PP, to which the TOE claims conformance. As such, they are outside the scope of the evaluation.The endpoint monitoring and control functionality is provided by three components: the User Activity Monitor(UAM); the File Integrity Monitor (FIM); and the Data Loss defender (DLD). All three components are disabled bydefault. In addition, the FIM requires a separate license.The product includes support for the use of a SQL Server for user authentication, but this option must be disabled inthe evaluated configuration. The TOE must be configured to use Windows Active Directory or the local Windowsoperating system for user authentication.The Security Target contains the following additional sections: TOE Description (Section 2)This section gives an overview of the TOE, describes the TOE in terms of its physical and logicalboundaries, and states the scope of the TOE. Security Problem Definition (Section 3)This section details the expectations of the environment, including the assumptions, organizational securitypolicies, and threats that are countered by the TOE and TOE environment. Security Objectives (Section 4)This section details the security objectives of the TOE and TOE environment. IT Security Requirements (Section 5)This section presents the security functional requirements (SFRs) for the TOE, and details the assurancerequirements for EAL2 augmented with ALC FLR.2. TOE Summary Specification (Section 6)This section describes the security functions represented in the TOE that satisfy the security requirements. Protection Profile Claims (Section 7)This section presents the Protection Profile claims and supporting rationale. Rationale (Section 8)This section closes the ST with the justifications of the security objectives, requirements and TOEsummary specifications as to their consistency, completeness, and suitability.1.1 Security Target, TOE and CC IdentificationST Title – LogRhythm Integrated Solution Security TargetST Version – Version 1.1ST Date –March 30, 2012TOE Identification – LogRhythm, Version 6.0.4 with Microsoft SQL Server 2008 R2 Enterprise EditionMay be reproduced only in its original entirety without revision.5
