According to the specialized threat hunting modules and frameworks withinFortiSOAR 7.6and the advanced analytics capabilities ofFortiSIEM 7.3, threat hunting is defined as a proactive, human-led search for threats that have bypassed automated security controls. The three selected activities are core components of this lifecycle:

Generate a hypothesis (C):This is the fundamental starting point of a "Structured Hunt." Analysts develop a testable theory—based on recent threat intelligence (such as a new TTP identified by FortiGuard) or environmental risk—about how an attacker might be operating undetected in the network.

Enrich records with threat intelligence (A):During the investigation phase, hunters use theThreat Intelligence Management (TIM)module in FortiSOAR to enrich technical data (IPs, hashes, URLs) with external context. This helps determine if an anomaly discovered during the hunt is indeed malicious or part of a known campaign.

Perform packet analysis (D):Since advanced threats often live in the "gaps" between log files, hunters frequently perform deep-packet or network-flow analysis using FortiSIEM’s query tools or integrated NDR (Network Detection and Response) data to identify suspicious lateral movement or C2 (Command and Control) communication patterns that standard alerts might miss.

Why other options are excluded:

Automate workflows (B):While SOAR is designed for automation, the act of "automating" is a DevOps or SOC engineering task. Threat hunting itself is a proactive investigation; while playbooks canassista hunter (e.g., by automating the data gathering), the act of hunting remains a manual or semi-automated cognitive process.

Tune correlation rules (E):Tuning rules is areactivemaintenance task or a "post-hunt" activity. Once a threat hunter finds a new attack pattern, they will then tune SIEM correlation rules to ensure that specific threat is detected automatically in the future. The tuning is theresultof the hunt, not the activity of hunting itself.

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.

In a modern Security Operations Center (SOC) environment powered byFortiSIEM 7.3andFortiSOAR 7.6, the efficiency of the incident response lifecycle depends on two primary pillars of analysis:

Accurate detection of threats (A):The primary goal of a SOC is to identify genuine malicious activity. Using FortiSIEM's correlation rules and machine learning (UEBA), the system must be tuned to detect patterns that signify real risk. Accuracy ensures that the SOC is not blinded by noise and can focus on critical security events that impact the organization's posture.

Rapid identification of false positives (C):"Alert Fatigue" is one of the greatest challenges in a SO

C.  

Analysts must be able to quickly distinguish between legitimate anomalies (false positives) and actual threats.FortiSOARassists in this by using automated playbooks to perform initial triage and "pre-processing"—such as checking IP reputations or verifying user activity—to automatically close or demote alerts that do not represent a true threat, thereby freeing up analysts for high-priority investigations.

Why other options are incorrect:

Immediate escalation for all alerts (B):This is a poor SOC practice. Escalating every alert without triage leads to analyst burnout and overloads senior responders with low-value tasks. The goal of a tiered SOC (Tier 1, Tier 2, Tier 3) is to filter alerts so only significant incidents are escalated.

Periodic system downtime (D):SOC systems (SIEM/SOAR) are considered "Mission Critical" and must operate on a24/7/365basis. Maintenance should be performed using High Availability (HA) configurations or during "low-flow" windows without causing a complete stop in monitoring, as attackers often leverage downtime to strike.

InFortiAnalyzer 7.6and related SOC versions, incidents serve as centralized containers for tracking and analyzing security events. There are two primary automated and manual methods to initiate an incident:

Using a custom event handler (A):In FortiAnalyzer, event handlers are used to generate events from raw logs.1A critical feature in recent versions is theAutomatically Create Incidentsetting within a custom event handler.2When enabled, the system automatically elevates a triggered event into a new incident record, allowing analysts to bypass the manual review of every individual event before an incident is raised.3

By running a playbook (D):Playbooks provide a powerful way to automate the incident lifecycle.4A playbook can be configured with anEvent Trigger, meaning it executes as soon as an event matches specific criteria. One of the core actions available within these playbooks is theCreate Incidentaction, which can automatically populate incident details, severity, and category based on the triggering event's data.5This ensures high-fidelity events are consistently captured for investigation.

Why other options are incorrect:

Using a connector action (B):While connectors allow FortiAnalyzer to communicate with external systems (like ITSM or Security Fabric devices), the act of "creating an incident"insideFortiAnalyzer is a function of the internal event engine or playbook automation, not a standalone connector action used for external integration.

Manually, on the Event Monitor page (C):While you can view, filter, and acknowledge events on theEvent Monitorpage, the process ofmanuallyraising an incident typically occurs from theIncidentsmodule or by right-clicking an event to "Raise Incident" in the Log View or FortiView, rather than being a core function defined as occurring "on the Event Monitor page" in the same architectural sense as handlers and playbooks.

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.

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.

The FortiSIEM rules engine evaluates subpatterns to detect complex attack behaviors. When a rule uses an aggregate condition likeCOUNT (Matched Events), the engine calculates this value based on specific architectural parameters:

Group By attributes (A):The engine maintains a separate counter for each unique combination of "Group By" attributes defined in the subpattern. For example, if you group by "Source IP," the engine tracks the count of events foreachunique IP address independently.

Time window (C):The count is relative to a specific time duration (e.g., 5 minutes). The engine only counts events that fall within this sliding or fixed window. Once an event falls outside this window, it is no longer included in the aggregate count.

Search filter (D):Only events that satisfy the specific "Search Filter" criteria (e.g., Event Type = "Failed Login") are considered "Matched Events." The filter defines the scope of the data that the rules engine processes before applying the count.

Why other options are incorrect:

Data source (B):While the data source determines where the logs come from, the rules engine itself uses the parsed attributes (defined in the search filter) rather than the raw data source to determine the count. Multiple data sources might contribute to the same filter and count.

Incident action (E):Incident actions (such as sending an email or triggering a SOAR playbook) are theresultof a rule firing. They do not influence the internal logic or calculation of the event count during the evaluation phase.

InFortiSOAR 7.6, manual playbooks appear in theExecutemenu of a record only if they meet specific configuration criteria defined in theManual Triggerstep:

Module Scope (C):When creating a playbook with a manual trigger, the administrator must explicitly select which modules (e.g., Alerts, Incidents, Indicators) can execute the playbook. If theAlertsmodule is not selected in the "Applicable Modules" section of the trigger configuration, the playbook will remain hidden from the Execute menu when an analyst is viewing the Alerts module.

Trigger Execution Requirements (D):Manual triggers can be configured to execute onno records, asingle record, ormultiple records. If a playbook is configured with the "Requires record input to run" setting but is specifically restricted to a different input type (or if there is a mismatch in the selection logic), it will not appear in the menu unless the correct number of records are selected. Furthermore, if a playbook is designed to run only whennorecord is selected (global utility), it will not show up in the context-sensitive menu of a specific record.

Why other options are incorrect:

Publishing (A):FortiSOAR playbooks do not require a separate "publishing" step via an Application Editor to become visible. Once they aresavedandactive(toggled on), they are immediately available for use based on their trigger settings.

Concurrent Execution (B):FortiSOAR allows multiple instances of the same playbook to run simultaneously. An active execution of a playbook does not hide it from the menu for other analysts or subsequent runs.
