NSE7_SOC_AR-7.6 Fortinet NSE 7 - Security Operations 7.6 Architect Questions and Answers

Comprehensive and Detailed Explanation From FortiSOAR 7.6., FortiSIEM 7.3 Exact Extract study guide:

In accordance with the MITRE ATT&CK mapping utilized byFortiSIEM 7.3andFortiSOAR 7.6, the described behaviors correspond to the following techniques:

Non-Standard Port (T1571):This technique involves adversaries communicating using a protocol and port pairing that are typically not associated. The incident report identifies HTTPS (TLS) traffic running onTCP 8443rather than the standard port 443.FortiSIEMspecifically includes built-in correlation rules, such as "Suspicious Typical Malware Back Connect Ports," designed to detect these protocol-port mismatches.

Exfiltration Over Alternative Protocol (T1048):This technique describes adversaries stealing data by exfiltrating it over a different protocol than the primary command and control (C2) channel. In this scenario, while the C2 channel is established via HTTPS on port 8443, the adversary is transferring staged files usingDNS queries with oversized TXT payloads. DNS is a common "alternative protocol" used to bypass standard data transfer monitoring and egress filtering.

Analysis of Incorrect Options:

Exploitation of Remote Services (B):This technique falls underInitial AccessorLateral Movementtactics, focusing on gaining entry into a system via vulnerabilities in network services like SMB or RDP. It does not apply to the maintenance of an established C2 channel or the exfiltration of data.

Hide Artifacts (D):This is aDefense Evasiontechnique where an adversary attempts to conceal their presence by removing traces such as log files or registry keys. While the attacker is "imitating normal traffic," the specific acts of using a non-standard port and DNS exfiltration are primary behavioral signatures defined by their own more specific techniques.

Understanding the Playbook Configuration:

The playbook named "Update Asset and Identity Database" is designed to update the FortiAnalyzer Asset and Identity database with endpoint and user information.

The exhibit shows the playbook with three main components: ON_SCHEDULE STARTER, GET_ENDPOINTS, and UPDATE_ASSET_AND_IDENTITY.

Analyzing the Components:

ON_SCHEDULE STARTER:This component indicates that the playbook is triggered on a schedule, not on-demand.

GET_ENDPOINTS:This action retrieves information about endpoints, suggesting it interacts with an endpoint management system.

UPDATE_ASSET_AND_IDENTITY:This action updates the FortiAnalyzer Asset and Identity database with the retrieved information.

Evaluating the Options:

Option A:The actions shown in the playbook are standard local actions that can be executed by the FortiAnalyzer, indicating the use of a local connector.

Option B:There is no indication that the playbook uses a FortiMail connector, as the tasks involve endpoint and identity management, not email.

Option C:The playbook is using an "ON_SCHEDULE" trigger, which contradicts the description of an on-demand trigger.

Option D:The action "GET_ENDPOINTS" suggests integration with an endpoint management system, likely FortiClient EMS, which manages endpoints and retrieves information from them.

Conclusion:

The playbook is configured to use a local connector for its actions.

It interacts with FortiClient EMS to get endpoint information and update the FortiAnalyzer Asset and Identity database.

Comprehensive and Detailed Explanation From FortiSOAR 7.6., FortiSIEM 7.3 Exact Extract study guide:

To establish a successful integration betweenFortiSOAR 7.6and aFortiGatefirewall via the FortiGate connector, specific administrative and network requirements must be met on the FortiGate side:

API Administrator and Key (D):FortiSOAR does not use standard UI login credentials. Instead, it requires aREST API Administratoraccount to be created on the FortiGate. This account must be assigned an administrative profile with the necessary permissions (e.g., Read/Write for Firewall policies or Address objects). Upon creation, the FortiGate generates a uniqueAPI Key, which must be entered into the "API Key" field of the FortiSOAR configuration wizard as shown in the exhibit.

HTTPS Management Access (C):The connector communicates with the FortiGate using REST API calls overHTTPS(port 443 by default). Therefore, the physical or logical interface on the FortiGate that corresponds to the "Hostname" IP (172.16.200.1) must haveHTTPSenabled under "Administrative Access" in its network settings. If HTTPS is disabled, the connection will time out or be refused.

Why other options are incorrect:

Trusted hosts (A):While it is a best practice to restrict API access to specific IPs (like the FortiSOAR IP), the integration can technically function without "Trusted hosts" enabled if the network allows the traffic. However, theabsenceof an API key or HTTPS access will definitively cause a failure regardless of trusted host settings.

VDOM name (B):In the exhibit, the VDOM field contains multiple values ("VDOM_1", "VDOM_2"). If VDOMs are disabled on the FortiGate, this field should generally be left blank or set to the default "root." Setting it specifically to "VDOM_1" when VDOMs are disabled is not a universal requirement for connectivity; the primary handshake depends on the API key and HTTPS connectivity.

Understanding the Requirements:

The objective is to create an incident and generate a report based on malicious attachment events detected by FortiAnalyzer from FortiSandbox analysis.

The endpoint hosts are protected by FortiClient EMS, which is integrated with FortiSandbox. All logs are sent to FortiAnalyzer.

Key Components:

FortiAnalyzer: Centralized logging and analysis for Fortinet devices.

FortiSandbox: Advanced threat protection system that analyzes suspicious files and URLs.

FortiClient EMS: Endpoint management system that integrates with FortiSandbox for endpoint protection.

Playbook Analysis:

The playbook in the exhibit consists of three main actions: GET_EVENTS, RUN_REPORT, and CREATE_INCIDENT.

EVENT_TRIGGER: Starts the playbook when an event occurs.

GET_EVENTS: Fetches relevant events.

RUN_REPORT: Generates a report based on the events.

CREATE_INCIDENT: Creates an incident in the incident management system.

Selecting the Correct Connector:

The correct connector should allow fetching events related to malicious attachments analyzed by FortiSandbox and facilitate integration with FortiAnalyzer.

Connector Options:

FortiSandbox Connector:

Directly integrates with FortiSandbox to fetch analysis results and events related to malicious attachments.

Best suited for getting detailed sandbox analysis results.

Selected as it is directly related to the requirement of handling FortiSandbox analysis events.

FortiClient EMS Connector:

Used for managing endpoint security and integrating with endpoint logs.

Not directly related to fetching sandbox analysis events.

Not selected as it is not directly related to the sandbox analysis events.

FortiMail Connector:

Used for email security and handling email-related logs and events.

Not applicable for sandbox analysis events.

Not selected as it does not relate to the sandbox analysis.

Local Connector:

Handles local events within FortiAnalyzer itself.

Might not be specific enough for fetching detailed sandbox analysis results.

Not selected as it may not provide the required integration with FortiSandbox.

Implementation Steps:

Step 1: Ensure FortiSandbox is configured to send analysis results to FortiAnalyzer.

Step 2: Use the FortiSandbox connector in the playbook to fetch events related to malicious attachments.

Step 3: Configure the GET_EVENTS action to use the FortiSandbox connector.

Step 4: Set up the RUN_REPORT and CREATE_INCIDENT actions based on the fetched events.

Fortinet Documentation on FortiSandbox Integration FortiSandbox Integration Guide

By using the FortiSandbox connector, the analyst can ensure that the playbook accurately fetches events based on FortiSandbox analysis and generates the required incident and report.

Collector2.Worker3.Supervisor4.Agent

The FortiSIEM 7.3 architecture is built upon a distributed multi-tenant model consisting of several distinct functional roles to ensure scalability and performance:

Supervisor:This is the primary management node in a FortiSIEM cluster. It hosts the Graphical User Interface (GUI), the Configuration Management Database (CMDB), and manages the overall system configurations, reporting, and dashboarding.

Worker:These nodes are responsible for the heavy lifting of data processing. They execute real-time event correlation against the rules engine, perform historical search queries, and handle the analytics workload to ensure the Supervisor node is not overwhelmed.

Collector:Collectors are typically deployed at remote sites or different network segments to offload log collection from the central cluster. They receive logs via Syslog, SNMP, or WMI, compress the data, and securely forward it to the Workers or Supervisor. They also perform performance monitoring of local devices.

Agent:These are lightweight software components installed directly on endpoints (Windows/Linux). Their primary role is to collect local endpoint logs, monitor file integrity (system changes), and track user activity that cannot be captured via traditional network-based logging.

Understanding the Event Handler Configuration:

The event handler is set up to detect specific security incidents, such as spearphishing, based on logs forwarded from other Fortinet products like FortiSandbox.

An event handler includes rules that define the conditions under which an event should be triggered.

Analyzing the Current Configuration:

The current event handler is named "Spearphishing handler" with a rule titled "Spearphishing Rule 1".

The log viewer shows that logs are being forwarded by FortiSandbox but no events are generated by FortiAnalyzer.

Key Components of Event Handling:

Log Type: Determines which type of logs will trigger the event handler.

Data Selector: Specifies the criteria that logs must meet to trigger an event.

Automation Stitch: Optional actions that can be triggered when an event occurs.

Notifications: Defines how alerts are communicated when an event is detected.

Issue Identification:

Since FortiSandbox logs are correctly forwarded but no event is generated, the issue likely lies in the data selector configuration or log type matching.

The data selector must be configured to include logs forwarded by FortiSandbox.

Solution:

B. Configure a FortiSandbox data selector and add it to the event handler:

By configuring a data selector specifically for FortiSandbox logs and adding it to the event handler, FortiAnalyzer can accurately identify and trigger events based on the forwarded logs.

Steps to Implement the Solution:

Step 1: Go to the Event Handler settings in FortiAnalyzer.

Step 2: Add a new data selector that includes criteria matching the logs forwarded by FortiSandbox (e.g., log subtype, malware detection details).

Step 3: Link this data selector to the existing spearphishing event handler.

Step 4: Save the configuration and test to ensure events are now being generated.

Conclusion:

The correct configuration of a FortiSandbox data selector within the event handler ensures that FortiAnalyzer can generate events based on relevant logs.

Fortinet Documentation on Event Handlers and Data Selectors FortiAnalyzer Event Handlers

Fortinet Knowledge Base for Configuring Data Selectors FortiAnalyzer Data Selectors

By configuring a FortiSandbox data selector and adding it to the event handler, FortiAnalyzer will be able to accurately generate events based on the appropriate logs.

1. Create a parameter in the child playbook.

2. Apply the parameter to the Disable User Account connector action.

3. Map data to the parameter in the Reference a playbook step in the parent playbook.

Comprehensive and Detailed Explanation From FortiSOAR 7.6., FortiSIEM 7.3 Exact Extract study guide:

InFortiSOAR 7.6, the methodology for passing data between playbooks—specifically from a parent to a "Referenced" (child) playbook—follows a strict data flow hierarchy:

Step 1: Create a parameter in the child playbook.Before a parent can send data, the child playbook must be configured to receive it. This is done by adding "Input Parameters" in theStartstep of the child playbook (configured as a "Referenced" trigger). These parameters act as the "inbox" for external data.

Step 2: Apply the parameter to the connector action.Once the child playbook has the parameter defined (e.g., user_id), you must use a Jinja expression like {{vars.input.params.user_id}} within the child's action steps (such as theActive Directory: Disable User Accountconnector) so that the child playbook actually utilizes the data it receives.

Step 3: Map data to the parameter in the parent playbook.Finally, in the parent playbook, when you add theReference a Playbookstep and select the child playbook, FortiSOAR automatically displays the parameters created in Step 1. You then map existing variables from the parent's environment (e.g., from a previous "Search by SamAccountName" step) into these fields to complete the hand-off.

Why other options are excluded:

Create a manual trigger and assign the user to a new variable:While manual triggers capture data, they are not the mechanism forpassingdata between nested playbooks; they are for user-to-system interaction.

Create a parameter in the parent playbook:Parameters in a parent playbook are used to receive data fromoutside(like an external API or manual input), not to send datadownto a child. The child defines what it needs; the parent simply provides it in the Reference step.

Understanding Automation Processes in FortiAnalyzer:

FortiAnalyzer can automate responses to detected security events, such as running commands on FortiGate devices.

Analyzing the Customer Requirement:

The customer wants to run a CLI command on FortiGate to block predefined URLs when a botnet C&C server IP is detected.

This requires an automated response triggered by a specific event.

Evaluating the Options:

Option A:Playbooks orchestrate complex workflows but are not typically used for direct event-triggered automation processes.

Option B:Data selectors filter logs based on criteria but do not initiate automation processes.

Option C:Event handlers can be configured to detect specific events (such as detecting a botnet C&C server IP) and trigger automation stitches to execute predefined actions.

Option D:Connectors facilitate communication between FortiAnalyzer and other systems but are not the primary mechanism for initiating automation based on log events.

Conclusion:

To start the automation process when a botnet C&C server IP is detected, you must use anEvent handlerin FortiAnalyzer.

Comprehensive and Detailed Explanation From FortiSOAR 7.6., FortiSIEM 7.3 Exact Extract study guide:

The built-in Jinja editor inFortiSOAR 7.6is a powerful utility designed to help playbook developers write and test complex data manipulation logic without having to execute the entire playbook. Its primary capabilities include:

Renders output (A):The editor provides a "Preview" or "Evaluation" pane. By combining aJinja expressionwith a sampleJSON input(manually entered or loaded), the editor dynamically calculates and displays the resulting output. This allows for immediate verification of data transformation logic.

Checks validity (B):The editor includes built-in linting and syntax validation. It alerts the developer to errors such as unclosed brackets, incorrect filter usage, or invalid syntax, ensuring that only valid Jinja code is saved into the playbook step.

Loads environment JSON (D):One of the most significant features for troubleshooting is the ability toload the environment JSONfrom a recent execution. This populates the editor's variable context (vars) with the actual data from a specific playbook run, allowing the developer to test expressions against real-world data that recently passed through the system.

Why other options are incorrect:

Creates new records in bulk (C):While Jinja expressions are used to format the data that goes into a record, the actual creation of records is handled by the"Create Record"step or specificConnectors, not by the Jinja editor utility itself.

Defines conditions to trigger a playbook step (E):Jinja is thelanguageused to write conditions within a "Decision" step or "Step Utilities," but the Jinja Editor is a tool forevaluating and testingthose expressions. The definition of the condition logic and the triggering behavior is a function of the Playbook Engine and Step configuration, not the editor's standalone capabilities.

Overview of Indicators of Compromise (IoCs): Indicators of Compromise (IoCs) are pieces of evidence that suggest a system may have been compromised. These can include unusual network traffic patterns, the presence of known malicious files, or other suspicious activities.

FortiAnalyzer's Role: FortiAnalyzer aggregates logs from various Fortinet devices to provide comprehensive visibility and analysis of network events. It uses these logs to identify potential IoCs and compromised hosts.

Relevant Log Types:

DNS Filter Logs:

DNS requests are a common vector for malware communication. Analyzing DNS filter logs helps in identifying suspicious domain queries, which can indicate malware attempting to communicate with command and control (C2) servers.

Comprehensive and Detailed Explanation From FortiSOAR 7.6., FortiSIEM 7.3 Exact Extract study guide:

Based on the official documentation forFortiSIEM 7.3(which utilizes the MITRE ATT&CK mapping for incident correlation) andFortiSOAR 7.6(which uses these tactics for incident classification and playbook triggering):

Reconnaissance (Tactic TA0043):This tactic consists of techniques that involve adversaries actively or passively gathering information that can be used to support targeting. In this scenario, the attacker identifies "employee names, roles, and email patterns from public press releases." This is categorized underGather Victim Org Information (T1591)andSearch Open Technical Databases (T1596). Since this activity happens prior to the compromise and involves gathering intelligence, it is strictly Reconnaissance.

Initial Access (Tactic TA0001):This tactic covers techniques that use various entry vectors to gain an initial foothold within a network. The act of sending "tailored emails... to recipients to review an attached agenda using a link" is the definition ofPhishing: Spearphishing Link (T1566.002). This is the specific delivery mechanism used to gain the initial entry.

Why other options are incorrect:

Discovery (B):This tactic involves techniques an adversary uses to gain knowledge about the internal network after they have already gained access. Since the attacker is looking at public press releases, they are operating outside the perimeter.

Defense Evasion (D):This tactic consists of techniques that adversaries use to avoid detection throughout their compromise. While using an external link might bypass some basic reputation filters, the primary goal described in the report is the act of establishing contact and access, which is the core of the Initial Access tactic.

Analyzing theQuery Configurationexhibit in the context of FortiSIEM 7.3 search logic reveals several syntax and logical errors that prevent the query from returning results:

Logical Operator Error (E):The user intends to find traffic to EuropeORAsia. In the exhibit, the first row (Group: Europe) is followed by a defaultANDoperator. This forces the query to look for a single flow where the destination is simultaneously in Europe and Asia, which is logically impossible. It must be changed toOR.

Missing Parentheses (C):When combiningORandANDlogic in FortiSIEM, parentheses are required to define the order of operations. Without them, the query might evaluate "Asia AND Destination Country IS NOT null AND Source IP IN..." first. To correctly find (Europe OR Asia) that also matches the LAN segment, parentheses must group the first two rows.

Incorrect Operator for IP Range (D):The exhibit uses theINoperator for the value 10.0.0.0, 10.200.200.254. In FortiSIEM, theINoperator is used for a comma-separated list of specific values or CMDB groups. To specify a continuous range of IP addresses (the "LAN segment"), theBETWEENoperator must be used.

Why other options are incorrect:

IS NOT null (A):In FortiSIEM, "IS NOT null" is a valid operator/value combination used to ensure a specific attribute has been successfully parsed and populated in the event record.

Time Range (B):There is no requirement for a time range to be "Absolute" when using CMDB groups; "Relative" time ranges (like the "Last 30 Days" shown) are commonly used and fully supported for such queries.

SOC Concepts and Frameworks

Comprehensive and Detailed Explanation From FortiSOAR 7.6., FortiSIEM 7.3 Exact Extract study guide:

In the context of the Fortinet Security Fabric,FortiAnalyzerperforms Indicator of Compromise (IOC) detection by correlating various security logs against a threat intelligence database.3The IOC engine specifically analyzes the following logs of each end user to identify potentially compromised hosts:

Web Filter Logs (A):The engine parses web filtering logs to identify access attempts to blacklisted URLs, malicious domains, or IPs associated with known malware distribution sites.4If a match is found in the threat database, the host is flagged as compromised.

DNS Filter Logs (C):DNS requests are a primary indicator of a compromise. The engine monitors these logs for queries directed at known Command and Control (C2) servers or domains generated by Domain Generation Algorithms (DGA).5

IPS Logs (E):Intrusion Prevention System (IPS) logs provide critical data on signature matches for known attacks. In newer Security Operations (SOC) curricula, IPS logs are used alongside Web and DNS logs to provide a high-fidelity assessment of whether a host is currently infected and attempting to communicate with an external threat actor.

Why other options are incorrect:

Email Filter Logs (B):While important for detecting phishing attempts (Initial Access), email logs are generally used for content filtering and antispam rather than being a primary source for the IOC engine's behavioral "calling home" detection in the FortiAnalyzer Compromised Hosts view.

Application Filter Logs (D):Application control logs provide visibility into software usage but are less commonly used by the core IOC engine for identifying blacklisted network destinations compared to Web and DNS filtering.

Understanding FortiAnalyzer Fabric Deployment:

FortiAnalyzer Fabric deployment involves a hierarchical structure where the Fabric root (supervisor) coordinates with multiple Fabric members (collectors and analyzers).

This setup ensures centralized log collection, analysis, and incident response across geographically distributed locations.

Analyzing the Exhibit:

FAZ1-Supervisoris located at AMER HQ and acts as the Fabric root.

FAZ2-Analyzeris a Fabric member located in EMEA.

FAZ3-CollectorandFAZ4-Collectorare Fabric members located in EMEA and APAC, respectively.

Evaluating the Options:

Option A:The statement indicates that the AMER HQ SOC team cannot run automation playbooks from the Fabric supervisor. This is true because automation playbooks and certain orchestration tasks typically require local execution capabilities which may not be fully supported on the supervisor node.

Option B:High availability (HA) configuration for the supervisor node is a best practice for redundancy but is not directly inferred from the given architecture.

Option C:The EMEA SOC team having access to historical logs only is not correct since FAZ2-Analyzer provides full analysis capabilities.

Option D:The APAC SOC team has access to FortiView and other reporting functions through FAZ4-Collector, but this is not explicitly detailed in the provided architecture.

Conclusion:

The most accurate observation about this FortiAnalyzer Fabric deployment architecture is that the AMER HQ SOC team cannot run automation playbooks from the Fabric supervisor.
