NSE7_SOC_AR-7.6 Exam Dumps : Fortinet NSE 7 - Security Operations 7.6 Architect

In the context of the Fortinet Security Fabric, FortiAnalyzer performs Indicator of Compromise (IOC) detection by correlating various security logs against a threat intelligence database. 3 The 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. 4 If 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.

Step 1: FortiSIEM event log

Step 2: FortiSIEM incident

Step 3: FortiSOAR alert

Step 4: FortiSOAR incident

Exact Extract: “FortiSIEM: Event: An event refers to a single log or data point collected from a monitored device. It’s the most basic unit of information received by FortiSIEM, such as a firewall log or a system alert.” The guide also states: “Incident: An incident in FortiSIEM is created when a correlation rule is triggered.”

Exact Extract: “This slide explains how to map fields between FortiSIEM incidents and FortiSOAR alerts during the ingestion process. Use the wizard to define how FortiSIEM data populates FortiSOAR alert fields.”

Exact Extract: “FortiSOAR ingests FortiSIEM incidents as alerts… If the alert is not a valid threat, then the analyst can close it as a false positive. Otherwise, the analyst can open an incident.”

The correct sequence is FortiSIEM event log → FortiSIEM incident → FortiSOAR alert → FortiSOAR incident . FortiSIEM first receives raw event logs from monitored devices. If those events match a correlation rule, FortiSIEM creates a FortiSIEM incident . The FortiSOAR default data ingestion wizard then ingests FortiSIEM incidents into FortiSOAR as alerts , not as FortiSOAR incidents directly. After triage and validation, the analyst or playbook can escalate the alert into a FortiSOAR incident .

Technical Deep Dive: FortiSIEM and FortiSOAR use different object models. FortiSIEM “incident” means a correlation result from event analytics. FortiSOAR “alert” is the first SOAR-side record created from that SIEM incident. FortiSOAR “incident” is a higher-level case-management container used after validation. This separation is intentional: not every SIEM incident deserves full incident-response handling. FortiGate NP/CP offloading is irrelevant because this workflow is log ingestion and case orchestration, not firewall packet acceleration.

Exact Extract: “MITRE ATT & CK classifies and describes cyberattacks and intrusions through 14 tactics… These categories are further broken down into specific techniques and subtechniques.”

Exact Extract: “The attacker then performs active reconnaissance using a mix of techniques, including port scanning and IP discovery, to find high-priority targets.”

The correct answers are A and D . The infected host first collected its own network configuration and connection details. That maps to System Network Connections Discovery , because MITRE defines this technique as attempting to list network connections to or from the compromised system. The later behavior—sending low-volume connection attempts to multiple internal addresses to identify responding hosts—maps best to Active Scanning , because MITRE describes active scanning as probing victim infrastructure through network traffic.

Network Sniffing is wrong because the scenario does not describe passive packet capture or monitoring traffic on an interface. Lateral Movement is also wrong because it is a MITRE tactic, not the best technique for host discovery activity. The host is still discovering reachable systems; it has not yet moved to another internal system.

Technical Deep Dive: In a Fortinet SOC investigation, this sequence is a classic post-compromise discovery pattern. Commands such as ipconfig, route print, netstat, Get-NetTCPConnection, or arp -a support System Network Connections Discovery. Low-rate probes to many internal IPs are often stealthier than noisy scans and may appear as sparse FortiGate traffic logs, Windows firewall events, or EDR telemetry. FortiSIEM should correlate this with source host, destination spread, port diversity, and time window. FortiGate NP/CP chips may accelerate allowed sessions, but detection occurs in FortiSIEM from logs and metadata, not inside the ASIC forwarding path.
