The applications monitor a configured set of network-attached devices and applications for status, performance and configuration settings. Depending on the size of the network, multiple instances of the applications may be deployed on different servers to provide adequate performance. For enhanced availability and robustness, a failover configuration may be deployed. The Orion suite consists of the following network, application, system, and storage monitoring components: SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 10 Orion Network Performance Monitor - Orion Network Performance Monitor (Orion NPM) provides the ability to detect, diagnose, and resolve performance issues with a dynamic network. It delivers real-time views and dashboards to visually display network performance. Automated network discovery features enable network managers to keep up with evolving networks. Orion Server & Application Monitor - Orion Server & Application Monitor (Orion SAM) brings agentless monitoring, alerting, and reporting capabilities to applications and servers. Automatically discovers servers and applications and provides visibility into application performance and the underlying operating systems and servers they run on. Orion Network Configuration Manager - Orion Network Configuration Manager (Orion NCM) notifies network managers in real-time when device configurations change, helping network managers determine which changes could potentially cause network issues. Orion NCM also provides nightly configuration backups, bulk configuration changes, user tracking, and inventory and compliance reporting. Orion NetFlow Traffic Analyzer - Orion NetFlow Traffic Analyzer (Orion NTA) enables network managers to quantify exactly how a network is being used, by whom, and for what purpose. The application mapping feature correlates the traffic arriving from designated ports, source IPs, destination IPs, and protocols to application names network managers can recognize. Orion NTA provides a comprehensive view of the network traffic, enabling network managers to find the bottlenecks or identify the bandwidth hogs. Orion IP Address Manager - Orion IP Address Manager (Orion IPAM) is an IP address management component that enables network managers to create, schedule, and share IP address space reports. Orion IPAM provides IP address management that is unified with performance monitoring data for a comprehensive view of network health. Orion Voice & Network Quality Manager - Orion Voice & Network Quality Manager (Orion VNQM) delivers a network and VoIP monitoring solution for identifying site-specific and WAN-related performance issues from the perspective of each of the remote sites. With this Orion component, network managers can utilize Cisco IP SLA technology with automatic VNQM setup to monitor key WAN performance metrics, including Cisco VoIP jitter and MOS. Orion User Device Tracker - Orion User Device Tracker (Orion UDT) delivers automated user and device tracking to monitor who and what are connecting to the network. Searches of the accumulated information can be performed on a user name, IP address, Hostname, or MAC address. UDT also provides the ability to send commands to network devices to shut down a port, but this functionality is not included in the evaluation. Orion Web Performance Monitor - Orion Web Performance Monitor (Orion WPM) continuously monitors the performance of web servers and applications. Performance issues can be identified as DNS look-up, connection time, send time, time to first byte, or content download time. Orion Storage Resource Monitor - Orion Storage Resource Monitor (Orion SRM) continuously monitors the status and performance of multi-vendor storage environments. Performance issues can be identified for NAS and SAN storage components as well as more granular entities such as volumes and storage pools. Orion Virtualization Manager - Orion Virtualization Manager (Orion VMAN) delivers integrated VMware vSphere® and Microsoft® Hyper-V® recommendations, capacity planning, SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 11 performance monitoring, VM sprawl control, VDI performance monitoring, configuration management, and alert remediation. VMAN provides a dashboard view of the health and status of applications, as well as all dependent virtual server, host, cluster, and datastore information that supports the application and its virtual server. Orion Enterprise Operations Console - Orion Enterprise Operations Console (Orion EOC) provides a consolidated command center to remotely monitor critical network infrastructure in multiple different physical locations. Orion EOC provides a consolidated command center to monitor the entire enterprise network and gives network managers unified visibility into remote Orion servers. The Orion suite provides the following capabilities to network managers:  Schedule network scans to identify new network devices or applications.  Perform detailed monitoring & analysis of performance data from routers, switches, servers, and applications to identify peak performance issues.  Monitor the health of critical applications.  Remotely monitor WMI performance counters to identify and resolve application issues.  Monitor the availability and responsiveness of critical DNS, IMAP4, and POP3 network services.  Get a comprehensive view of network traffic on a single page, or drill down into any element’s traffic.  Break down the display of network traffic information by application.  Identify network issues across the enterprise.  Configure alerts for correlated events, sustained conditions, or complex combinations of device states.  Generate reports for network performance, application performance and server availability.  Schedule and automatically backup network device configurations on a regular basis for routers, switches, firewalls, and wireless access points.  Receive real-time alerts when configurations change on monitored resources.  Generate a detailed network inventory of all managed devices, including serial numbers, port details, and IP addresses.  Perform remote IOS/firmware updates in real time or schedule them to run at a future time.  Generate configuration change reports for monitored resources  Establish unique accounts and specify which types of information are displayed for a particular user. SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 12  Create a custom poller to monitor any SNMP-enabled device, collect detailed data from MIB tables, & monitor virtually any statistic available on network devices. This functionality is not evaluated.  Install additional polling engines for large networks with a small number of NPM or SAM instances. This functionality is not evaluated.  Install additional web servers to support a large number of network managers. This functionality is not evaluated. Users may interact with the TOE via multiple interfaces. The EOC Web Console provides access to the EOC, and through it provides visibility to the overall TOE, which is especially useful when multiple Orion Servers are deployed. The Orion Web Console provides access to individual Orion Servers. All of these interfaces support connections from remote IT systems via web browsers. User access to information via each of these interfaces is controlled by the roles configured for individual users by administrators. When a connection is established, the user is prompted for a username and password. User credential validation is performed by the TOE for the Orion Web Console interface, and by Windows for the EOC Web Console interface. In all cases, permitted user accounts must be defined within the TOE so that user-specific TOE parameters (e.g. role) can be associated with each user. 1.5.2 TOE type Network Management 1.5.3 Required Non-TOE Hardware/Software/Firmware The TOE consists of applications installed on multiple server types: 1. EOC Server - EOC installed on a dedicated server. 2. Orion Server - Orion Suite components (other than EOC) installed on a dedicated server. Any combination of components may be installed with each instance. Any combination is generically referred to as an Orion Server.

Audit - Audit records are generated for specific actions performed by users. The audit records are stored in the Orion database and may be viewed via the Orion Web Console by authorized administrators. 2. Identification and Authentication – When a connection is established to the EOC Web Console or Orion Web Console, the TOE prompts the user for login credentials. The credentials are validated by the TOE for the Orion Web Console. For the EOC Web Console, the credentials are first passed to Windows for validation. 3. Management – Management functionality is provided to authorized users. The functionality provided to individual users is determined by the user’s role, which is one of the security attributes for users. 4. Network Monitoring – The status and performance of managed elements are monitored. The results are saved and may be viewed by authorized users. Access to data about the managed elements may be limited by view limitations. Alerts may be generated to notify network managers of configured conditions detected about the managed elements. Conditions detected by Orion include element status changes and performance threshold values being exceeded. 5. Configuration Management – The configurations of network devices may be downloaded from the network device, saved in the TOE database, and compared to a reference configuration. If a configuration change is detected, an upload of a saved configuration for the network device may be triggered. 1.7 Functionality Excluded From the Evaluation The following functionality included in the Orion suite is not evaluated:  Create a custom poller to monitor any SNMP-enabled device, collect detailed data from MIB tables, & monitor virtually any statistic available on network devices.  Install additional polling engines for large networks with a small number of NPM or SAM instances.  Install additional web servers to support a large number of network managers.  External web sites are not added to Orion Web Console views.  The “Check for product updates” function is not used.  Custom device pollers are not configured.

Security Requirements This section contains the functional requirements that are provided by the TOE. These requirements consist of functional components from Part 2 of the CC. The CC defines operations on security requirements. The font conventions listed below state the conventions used in this ST to identify the operations. Assignment: indicated in italics Selection: indicated in underlined text Assignments within selections: indicated in italics and underlined text Refinement: indicated with bold text Iterations of security functional requirements may be included. If so, iterations are specified at the component level and all elements of the component are repeated. Iterations are identified by numbers in parentheses following the component or element (e.g., FAU_ARP.1(1)). 6.1 TOE Security Functional Requirements The functional requirements are described in detail in the following subsections. Additionally, these requirements are derived verbatim from Part 2 of the Common Criteria for Information Technology Security Evaluation with the exception of completed operations. 6.1.1 Security Audit (FAU) 6.1.1.1 FAU_GEN.1 Audit Data Generation FAU_GEN.1.1 The TSF shall be able to generate an audit record of the following auditable events: a) Start-up and shutdown of the audit functions; b) All auditable events for the not specified level of audit; and c) The events in the following table. Table 11 - Auditable Events SFR Event Details FAU_GEN.1 Changes to the Enable Audit Trail setting Old and new setting values FIA_ATD.1 User account creation and deletion User account FIA_UAU.2 Successful login User identity, IP address of the remote system FIA_UID.2 Successful login User identity, IP address of the remote system FMT_MTD.1 Modifications to the values of system parameters Parameter changed, old and new values Creation, modification and deletion of monitoring entities (e.g. Node, Application Template) Action, entity type, entity name, associated Node (if applicable), old and new values (for Node properties) Node managed or unmanaged Action, Node FAU_GEN.1.2 The TSF shall record within each audit record at least the following information: SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 39 a) Date and time of the event, type of event, subject identity (if applicable), and the outcome (success or failure) of the event; and b) For each audit event type, based on the auditable event definitions of the functional components included in the PP/ST, the information specified in the Details column of the table above. 6.1.1.2 FAU_SAR.1 Audit Review FAU_SAR.1.1 The TSF shall provide all Orion Administrators with the capability to read all data from the audit records. FAU_SAR.1.2 The TSF shall provide the audit records in a manner suitable for the user to interpret the information. 6.1.1.3 FAU_SAR.2 Restricted Audit Review FAU_SAR.2.1 The TSF shall prohibit all users read access to the audit records, except those users that have been granted explicit read-access. 6.1.2 Identification and Authentication (FIA) 6.1.2.1 FIA_ATD.1 User Attribute Definition Refinement Rationale: The TOE provides multiple access mechanisms for users. The security attributes defined for the users vary based upon the mechanism, with the exception of Orion Windows Applications where the only attribute (the role) is implied. Therefore, iterations for this SFR are specified for individual access mechanisms. The collection of iterations addresses the user attribute definitions for the TOE access mechanisms. 6.1.2.1.1 FIA_ATD.1(1) User Attribute Definition (Orion Web Console) FIA_ATD.1.1(1) The TSF shall maintain the following list of security attributes belonging to individual users of the Orion Web Console: 1. Username 2. Password 3. Account enabled status 4. Account expiration date 5. Allow administrator rights (role) 6. Allow Node management 7. Allow Report management 8. Allow account to clear Events, acknowledge Alerts and Syslogs 9. Alert sound 10. Menu Bar assignments 11. Report folder SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 40 12. NCM Role 13. IPAM Role 14. SAM Role 15. Allow Account to Unmanage Objects Application Note: Different security attributes are maintained for different TOE access mechanisms. This iteration applies to security attributes for users of the Orion Web Console. 6.1.2.1.2 FIA_ATD.1(2) User Attribute Definition (EOC Web Console) FIA_ATD.1.1(2) The TSF shall maintain the following list of security attributes belonging to individual users of the EOC Web Console: 1. Username 2. Role 3. Accessible Orion Servers 4. Orion Server Credentials user-supplied or admin-supplied 5. Orion Server Credentials Application Note: Different security attributes are maintained for different TOE access mechanisms. This iteration applies to security attributes for users of the EOC Web Console. 6.1.2.2 FIA_UAU.2 User Authentication Before any Action Refinement Rationale: This SFR applies to password validation for the Orion Web Console. Password validation for the EOC Web Console is performed by Windows; Windows is responsible for the complete I&A process for Windows applications that invoke the TOE. FIA_UAU.2.1 The TSF shall require each Orion Web Console user to be successfully authenticated before allowing any other TSF-mediated actions on behalf of that user. 6.1.2.3 FIA_UAU.7 Protected Authentication Feedback FIA_UAU.7.1 The TSF shall provide only dots to the user while the authentication is in progress. Application Note: This SFR does not apply to instances when the password is passed to the TOE using URL parameters. 6.1.2.4 FIA_UID.2 User Identification Before any Action Refinement Rationale: This SFR applies to users accessing the TOE via the Orion Web Console or the EOC Web Console. The TOE does not perform any identification for users accessing the TOE via Orion Windows applications on servers on which Orion Server components are installed. Identification must be performed by Windows prior to the users invoking the applications, as specified in OE.WINDOWSACCESS. FIA_UID.2.1 The TSF shall require each Orion Web Console and EOC Web Console user to be successfully identified before allowing any other TSF-mediated actions on behalf of that user. SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 41 6.1.2.5 FIA_USB.1 User-Subject Binding Refinement Rationale: The TOE provides multiple access mechanisms for users. The security attributes bound to a session for the users vary based upon the mechanism. Therefore, iterations for this SFR are specified for each access mechanism. The collection of iterations addresses the user attribute definition for all TOE access mechanisms. 6.1.2.5.1 FIA_USB.1(1) User-Subject Binding (Orion Web Console) FIA_USB.1.1(1) The TSF shall associate the following user security attributes with subjects acting on behalf of that Orion Web Console user: 1. Username 2. Allow administrator rights (role) 3. Allow Node management rights 4. Allow Report management rights 5. Allow account to clear Events, acknowledge Alerts and Syslogs 6. Alert sound 7. Menu Bar assignments 8. Report folder 9. NCM Role 10. IPAM Role 11. SAM Role 12. Allow Account to Unmanage Objects FIA_USB.1.2(1) The TSF shall enforce the following rules on the initial association of user security attributes with subjects acting on the behalf of Orion Web Console users: attributes are bound from the configured parameters for the identified user account. FIA_USB.1.3(1) The TSF shall enforce the following rules governing changes to the user security attributes associated with subjects acting on the behalf of Orion Web Console users: User permissions (e.g. Allow administrator rights, NCM Role, IPAM Role) are dynamically retrieved and re-bound as interactions are invoked; Menu Bar assignments are re-bound whenever a Menu Bar parameter is selected by the user; other subject attributes do not change during a session. Application Note: Different security attributes are bound for different TOE access mechanisms. This iteration applies to security attributes for users of the Orion Web Console. 6.1.2.5.2 FIA_USB.1(2) User-Subject Binding (EOC Web Console) FIA_USB.1.1(2) The TSF shall associate the following user security attributes with subjects acting on behalf of that EOC Web Console user: 1. Username 2. Role 3. Accessible Orion Servers SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 42 4. Orion Server Credentials user-supplied or admin-supplied 5. Orion Server credentials FIA_USB.1.2(2) The TSF shall enforce the following rules on the initial association of user security attributes with subjects acting on the behalf of EOC Web Console users: attributes are bound from the configured parameters for the identified user account. FIA_USB.1.3(2) The TSF shall enforce the following rules governing changes to the user security attributes associated with subjects acting on the behalf of EOC Web Console users: subject attributes do not change during a session. Application Note: Different security attributes are bound for different TOE access mechanisms. This iteration applies to security attributes for users of the EOC Web Console. 6.1.2.5.3 FIA_USB.1(3) User-Subject Binding (Orion Windows Applications) FIA_USB.1.1(3) The TSF shall associate the following user security attributes with subjects acting on behalf of that Orion Windows applications user: 1. Role (Windows Application Administrator) FIA_USB.1.2(3) The TSF shall enforce the following rules on the initial association of user security attributes with subjects acting on the behalf of Orion Windows applications users: the role is implied by use of the access mechanism. FIA_USB.1.3(3) The TSF shall enforce the following rules governing changes to the user security attributes associated with subjects acting on the behalf of Orion Windows applications users: subject attributes do not change during a session. Application Note: Different security attributes are bound for different TOE access mechanisms. This iteration applies to security attributes for users of the Orion Windows applications. 6.1.3 Security Management (FMT) 6.1.3.1 FMT_MTD.1 Management of TSF Data Application Note: The TOE provides multiple management access mechanisms for users. The TSF data privileges for the users vary based upon the mechanism. Therefore, iterations for this SFR are specified for each access mechanism. The collection of iterations addresses the TSF data privileges for all TOE access mechanisms. If a TSF data item is not included in the table accompanying the SFR iteration, then no access to that TSF data item is provided via the TOE access mechanism. 6.1.3.1.1 FMT_MTD.1(1) Management of TSF Data (Orion Server TSF Data (Other Than NCM-Specific, SAM-Specific and IPAM-Specific)) FMT_MTD.1.1(1) The TSF shall restrict the ability to query, modify, delete, create, acknowledge the Orion Server TSF data (other than NCM-specific, SAM-specific and IPAM- specific) specified in the following table to users with the roles and permissions specified in the following table. Application Note: Different TSF data privileges are enforced for different TOE access mechanisms. This iteration applies to TSF data (other than NCM-specific, SAM-specific and IPAM-specific) for Orion Servers. Access limitations for the NCM-specific, SAM-specific and IPAM-specific data is controlled via an additional security attribute (NCM, SAM or IPAM role) assigned to individual user accounts and is addressed in separate iterations of this SFR.

Application Note: The TOE monitors a variety of status and performance indicators for managed elements; the specific items are dependent on the type of elements being monitored. Administrators may configure alerts to be generated SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 49 based on status changes of managed elements (e.g. node down) or performance threshold values being exceeded (e.g. CPU utilization of a server exceeds a threshold value). 6.1.4.4 FNM_RDR.1 Restricted Data Review Application Note: Different Monitor data privileges are enforced for different TOE access mechanisms and categories of data. The first iteration applies to all Monitor data specific on a specific Orion Server instance other than configuration files uploaded from monitored devices. The second iteration deals specific with device configuration files since access privileges are based on NCM roles and not all Orion user accounts have an NCM role assigned.. The third iteration specifies access from EOC, since individual EOC user accounts may be configured to have access to different subsets of Orion servers. 6.1.4.4.1 FNM_RDR.1(1) Restricted Data Review (Authorized Orion Web Console Users) FNM_RDR.1.1(1) The TSF shall provide authorized Orion Web Console users with the capability to read Monitor data other than device configuration data from the Monitor data. FNM_RDR.1.2(1) The TSF shall provide the Monitor data in a manner suitable for the user to interpret the information. FNM_RDR.1.3(1) The TSF shall prohibit all users read access to the Monitor data, except those users that have been granted explicit read-access. 6.1.4.4.2 FNM_RDR.1(2) Restricted Data Review (Authorized Orion Web Console Users That Have NCM Roles Configured) FNM_RDR.1.1(2) The TSF shall provide authorized Orion Web Console users that have NCM roles configured with the capability to read device configuration data from the Monitor data.

TOE Summary Specification 7.1 Security Functions 7.1.1 Audit Relevant SFRs: FAU_GEN.1, FAU_SAR.1, FAU_SAR.2 The TOE generates audits for the events specified in the table included with FAU_GEN.1. Startup and shutdown of the audit function is controlled by changes to the Enable Audit Trail setting; the evaluated configuration requires this value to be set at all times. The following fields are included in all audit log records, although not all fields are populated in all records:  Date/time  Message (details of the event)  User performing the action Audit records are stored in plaintext in the Orion database for the time period configured via the Audit Trails Retention parameter, and are automatically deleted when the retention period expires. Audit records may be viewed via the Orion Web Console using the Message Center View by Administrators. Users are not permitted to read audit records. 7.1.2 Identification and Authentication Relevant SFRs: FIA_ATD.1(all iterations), FIA_UAU.2, FIA_UAU.7, FIA_UID.2, FIA_USB.1(all iterations), FTA_SSL.3 The TOE provides the following access mechanism for users to interact with the TOE: 1. Orion Web Console 2. EOC Web Console 3. Orion Windows applications invoked on servers hosting TOE components The first two mechanisms are accessed via web browsers from remote IT systems, while the last is accessed by users from the local keyboard/display on the servers hosting the TOE components. When a connection is established to the Orion Web Console, the TOE collects a username and password from the user. A dot (“•”) is echoed for each character supplied for the password (FIA_UAU.7). Once the credentials are supplied, they are validated by the TOE (FIA_UID.2, FIA_UAU.2). If the credentials are not valid, the user account is not enabled, or the user account has expired, an error message is displayed and the user may try again. If the credentials are valid, the security attributes configured for the supplied username (FIA_ATD.1(1)) are bound to the session (FIA_USB.1(1)) and the user is given access to the management functions. The attributes bound to the session are specified in FIA_USB.1(1). Sessions are automatically terminated after the configured inactivity time (FTA_SSL.3). When a connection is established to the EOC Web Console, the TOE collects a username and password from the user. A dot (“•”) is echoed for each character supplied for the password (FIA_UAU.7). Once the credentials are supplied, they are passed to the host operating system (Windows) for validation. If the credentials are not valid, an error message is displayed and the SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 53 user may try again. If the credentials are valid, the supplied username is checked against the user accounts defined for the EOC Web Console (FIA_UID.2). If the account is not defined, an error message is displayed and the user may try again. If the user account is defined, the security attributes configured for the supplied username (FIA_ATD.1(2)) are bound to the session (FIA_USB.1(2)) and the user is given access to the management functions. The attributes bound to the session are specified in FIA_USB.1(2). When the Orion Server is invoked via a Windows application, the TOE does not perform any I&A function. The user is required to have been identified by Windows (per OE.WINDOWSACCESS). The role bound to all users of this access mechanism is set to the Windows Application Administrator role (FIA_USB.1(3)). When a user of the EOC Web Console accesses data from an Orion Server, credentials for the user are automatically sent to the server on behalf of the user. If the user account is configured to use the configured credentials, the credentials used are those configured for the user account. Otherwise, the user is prompted for the credentials to send. A dot (“•”) is echoed for each character supplied for the password (FIA_UAU.7). When a user of the EOC Web Console or Orion Web Console accesses configuration data (related to NCM) for a Node, the NCM role configured for the Orion Server user account is bound to the session. 7.1.3 Management Relevant SFRs: FMT_MTD.1(all iterations), FMT_SMF.1, FMT_SMR.1 Management functionality is available to authorized users through the Orion Web Console, the EOC Web Console, and Windows applications invoked on the Orion Servers. The management functionality available to users is specified in FMT_SMF.1. The functionality made available to individual users is dependent on their security attributes (including role), which vary based upon the TOE access mechanism being used. The roles are specified in FMT_SMR.1, and the access privileges available and associated security attributes are specified in FMT_MTD.1. 7.1.4 Network Monitoring Relevant SFRs: FNM_ANL.1, FNM_MDC.1, FNM_RCT.1, FNM_RDR.1(all iterations), FNM_STG.1 Network monitoring is performed against Managed Elements by Orion Servers. The types of monitoring is dependent on the TOE components installed on the Orion Servers, and may include nodes, interfaces, servers, applications, IP address space, network flows, and SLAs. Performance monitoring is performed by sending ICMP and/or SNMP messages to the Managed Elements to determine configuration information and retrieve status and statistics information (FNM_MDC.1). Status information may also be determined from Syslog and/or SNMP Trap messages received from the Managed Elements, or via WMI exchanges to determine information about servers and applications. Information collected from the managed elements is analyzed (FNM_ANL.1). The TOE analyzes for a variety of status and performance indicators for managed elements; the specific items are dependent on the type of elements being monitored. The results of the analysis are available to users of the TOE via Views (FNM_RDR.1). Events are generated to record status changes or configured threshold values being met concerning the managed elements SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 54 (FNM_ANL.1), and Alerts may be generated based upon these conditions being detected about the managed elements (FNM_RCT.1). Administrators may configure alerts to be generated based on status changes of managed elements (e.g. node down) or performance threshold values being exceeded (e.g. CPU utilization of a server exceeds a threshold value). Alerts may cause notifications such as Syslog messages or SNMP Trap messages sent to configured destinations. The results of the analysis are available to users of the TOE via Views (FNM_RDR.1). Views may be accessed via the Orion Web Console, which provides information concerning Managed Elements configured in a specific Orion Server instance; or the EOC Web Console, which provides aggregated information from one or more Orion Server instances, depending on the configuration for individual EOC Web Console users. Access privileges for status and analysis information maintained by the Orion Server is determined by the user account privileges configured for each authorized Orion Server user account. The information collected from the managed elements, as well as the analysis results, is saved in the TOE database and may be reviewed by authorized users (FNM_STG.1). The TOE does not provide any direct database access to Orion Web Console or EOC Web Console users, and the mediated access does not provide any mechanism to modify the Monitor data. The only mechanism provided to delete Monitor data is via the configuration of data retention policies by authorized administrators. 7.1.5 Configuration Management Relevant SFRs: FMT_MTD.1(2), FNM_ANL.1, FNM_RCT.1 The TOE downloads configuration files from network nodes either on command by an authorized NCM user or according to scheduled NCM jobs (FMT_MTD.1(2)). Configuration files may also be uploaded to network nodes on command by an authorized NCM user or according to scheduled NCM jobs (FMT_MTD.1(2)). When configuration files are downloaded, they may be compared to previously downloaded files to detect changes (FNM_ANL.1). Syslog messages received from the network nodes may also be analyzed to detect configuration changes (FNM_ANL.1). Detection of a configuration change can trigger the upload of a configuration file to a network node (FNM_RCT.1).

Rationale This chapter provides the rationale for the selection of the IT security requirements, objectives, assumptions and threats. 8.1 Rationale for IT Security Objectives This section of the ST demonstrates that the identified security objectives are covering all aspects of the security needs. This includes showing that each threat, assumption and organisational security policy is addressed by a security objective. The following table identifies for each threat and assumption, the security objective(s) that address it.

Table 20 - Threats, Assumptions and Organisational Security Policies to Security Objectives Rationale x.TYPE Security Objectives Rationale A.ACCESS The OE.INTROP objective ensures the TOE has the needed access. A.ASCOPE The OE.INSTALL objective ensures the TOE is installed per the vendor guidance, which addresses scalability. A.DATABASE The OE.DATABASE objective ensures that access to any mechanisms outside the TOE boundary that may be used to access the database is configured by the administrators such that only authorized users may utilize the mechanisms. A.ENVIRON OE.ENVIRON addresses this assumption by restating it as an objective for the Administrator to satisfy. A.INSTALL OE.INSTALL addresses this assumption by restating it as an objective for the Administrator to satisfy. A.NETWORK OE.NETWORK addresses this assumption by restating it as an objective for the Administrator to satisfy. A.NOEVILADM IN OE.NOEVILADMIN addresses this assumption by restating it as an objective for the Administrator to satisfy. P.ACCACT The O.AUDITS objective implements this policy by requiring auditing of all data accesses and use of TOE functions. The OE.TIME objective supports this policy by providing a time stamp for insertion into the audit records. The O.TOE_ACCESS objective supports this objective by ensuring each user is identified and authenticated. P.ACCESS O.MANAGE defines the access privileges to the data for the supported roles. O.TOE_ACCESS requires the TOE to control access based upon the user’s role. OE.WINDOWSACCESS requires Windows to restrict access to Orion Server functionality via Windows applications to users authorized to invoke TOE functionality. P.ANALYZ O.CONFIG requires the TOE to be able to compare configuration files for managed elements to detect unexpected changes. O.MONITOR requires the TOE to analyze information collected from the managed elements to detect conditions specified by administrators. P.DBMONITOR OE.DBMONITOR addresses this policy by restating it as an objective for the Administrator to satisfy. P.DISCLOSURE OE.COMM addresses the policy by requiring the environment to supply functionality to protect the communication between remote systems and TOE components. OE.CRYPTO addresses the policy by requiring the environment to provide cryptographic functionality in support of data protection protocols such as SSL. OE.SSL addresses the policy by requiring the environment to provide SSL as a data protection protocol. P.INTGTY O.MANAGE requires the TOE to define the required functionality, which also implicitly defines the lack of functionality for modification of collected data. P.MANAGE O.TOE_ACCESS requires the TOE to control access based upon the user’s role, which requires the TOE to bind a role to each user’s session. OE.WINDOWSACCESS requires Windows to restrict access to Orion Server functionality via Windows applications to users authorized to invoke TOE functionality. P.PASSWORDS O.PASSWORDS addresses this policy by requiring the TOE to provide functionality for Administrators, but not non-Administrators, to configure passwords. SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 57 x.TYPE Security Objectives Rationale T.INTERCEPT OE.CRYPTO mitigates the threat by requiring the environment to provide cryptographic functionality in support of secure communication channels. T.MASQUERAD E O.TOE_ACCESS mitigates this threat by controlling the logical access to the TOE and its resources. By constraining how and when authorized users can access the TOE this objective helps mitigate the possibility of a user attempting to login and masquerade as an authorized user. OE.COMM mitigates this threat by protecting data when it is transferred between remote systems and the TOE. OE.WINDOWSACCESS requires Windows to identify and authenticate users before they access Orion Server functionality via Windows applications. T.TSF_COMPR OMISE O.MANAGE is necessary because an access control policy is not specified to control access to TSF data. This objective is used to dictate who is able to view and modify TSF data. T.UNIDENT_AC TIONS The O.AUDITS objective helps to mitigate this threat by recording actions for later review. The O.AUDIT_REVIEW objective helps to mitigate this threat by providing the Administrator with the ability to review the actions taken by administrators. The OE.TIME helps to mitigate this threat by ensuring that correct timestamps are available for audit records. 8.2 Security Requirements Rationale 8.2.1 Rationale for Security Functional Requirements of the TOE Objectives This section provides rationale for the Security Functional Requirements demonstrating that the SFRs are suitable to address the security objectives. The following table identifies for each TOE security objective, the SFR(s) that address it.

Table 22 - Security Objectives to SFR Rationale Security Objective SFR and Rationale O.AUDITS FAU_GEN.1 requires the TOE to generate audit log records for a specified set of security-relevant events. O.AUDIT_REVI EW FAU_SAR.1 requires the TOE to provide authorized users with a mechanism to review audit logs. FAU_SAR.2 requires the TOE to prevent unauthorized users from reading the audit logs. O.CONFIG FMT_MTD.1(2) defines the roles that may perform configuration management operations with the managed elements. FNM_ANL.1 requires the TOE be able to compare configuration files for managed elements. FNM_MDC.1 requires the TOE be able to upload, download, and compare configuration files for managed elements. FNM_RDR.1(2) requires that configuration file comparisons (analysis results) be able to be viewed in human readable form. FNM_STG.1 requires the TOE to protect configuration files from modification or unauthorized deletion. O.MANAGE FIA_ATD.1 define the security attributes that must be able to be managed for users of the TOE. FMT_MTD.1 define the data access privileges associated with each role. FMT_SMF.1 defines the specific security management functions to be supported. FMT_SMR.1 defines the specific security roles to be supported. FNM_RDR.1 requires the TOE to provide information collected from managed elements to be displayed in human readable form. SolarWinds Orion Software Security Target Copyright © 2018 SolarWinds Worldwide, LLC. 59 Security Objective SFR and Rationale O.MONITOR FNM_MDC.1 requires the TOE be able to collect and save information about the managed elements FNM_ANL.1 requires the TOE to be able to analyze the information collected about the managed elements. FNM_RCT.1 requires the TOE be able to generate alerts upon detection of configured conditions concerning the managed elements. FNM_RDR.1(all iterations) requires that data collected about the managed elements and analysis results be able to be viewed in human readable form. FNM_STG.1 requires the TOE to protect configuration files from modification or unauthorized deletion. O.PASSWORDS FMT_MTD.1(1) defines the access privileges for Administrators and non- Administrators, stating that only Administrators may configure passwords. FMT_SMR.1 defines the specific security roles to be supported. O.TOE_ACCESS FIA_ATD.1 defines the attributes of users, including a userid that is used by the TOE to determine a user’s identity and enforce what type of access the user has to the TOE (e.g., the TOE associates a userid with a role). FIA_UID.2 requires that a user be identified to the TOE in order to access TOE functionality or data. FIA_UAU.2 requires that a user of the Orion Web Console be authenticated by the TOE before accessing TOE functionality or data. FIA_UAU.7 provides that the authentication data provided by the user is not echoed back in plaintext, thus serving to protect that data. FIA_USB.1 defines the attributes that are bound to user sessions for the access mechanisms provided by the TOE. FTA_SSL.3 requires the TOE to automatically terminate user sessions that are inactive, which protects against unauthorized users gaining access via a “forgotten” session. 8.2.2 Security Assurance Requirements Rationale The TOE stresses assurance through vendor actions that are within the bounds of current best commercial practice. The TOE provides, primarily via review of vendor-supplied evidence, independent confirmation that these actions have been competently performed. The general level of assurance for the TOE is: A) Consistent with current best commercial practice for IT development and provides a product that is competitive against non-evaluated products with respect to functionality, performance, cost, and time-to-market. B) The TOE assurance also meets current constraints on widespread acceptance, by expressing its claims against EAL2 augmented by ALC_FLR.2 from part 3 of the Common Criteria.
