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.

IPS Logs:

Intrusion Prevention System (IPS) logs detect and block exploit attempts and malicious activities. These logs are critical for identifying compromised hosts based on detected intrusion attempts or behaviors matching known attack patterns.

Web Filter Logs:

Web filtering logs monitor and control access to web content. These logs can reveal access to malicious websites, download of malware, or other web-based threats, indicating a compromised host.

Why Not Other Log Types:

Email Filter Logs:

While important for detecting phishing and email-based threats, they are not as directly indicative of compromised hosts as DNS, IPS, and Web filter logs.

Application Filter Logs:

These logs control application usage but are less likely to directly indicate compromised hosts compared to the selected logs.

Detailed Process:

Step 1: FortiAnalyzer collects logs from FortiGate and other Fortinet devices.

Step 2: DNS filter logs are analyzed to detect unusual or malicious domain queries.

Step 3: IPS logs are reviewed for any intrusion attempts or suspicious activities.

Step 4: Web filter logs are checked for access to malicious websites or downloads.

Step 5: FortiAnalyzer correlates the information from these logs to identify potential IoCs and compromised hosts.

Fortinet Documentation: FortiOS DNS Filter, IPS, and Web Filter administration guides.

Understanding FortiAnalyzer Fabric Topology:

The FortiAnalyzer Fabric topology is designed to centralize logging and analysis across multiple devices in a network.

It involves a hierarchy where the supervisor node manages and coordinates with other Fabric members.

Analyzing the Options:

Option A: Downstream collectors forwarding logs to Fabric members is not a typical configuration. Instead, logs are usually centralized to the supervisor.

Option B: For effective management and log centralization, logging devices must be registered to the supervisor. This ensures proper log collection and coordination.

Option C: The supervisor does not primarily use an API to store logs, incidents, and events locally. Logs are stored directly in the FortiAnalyzer database.

Option D: For the Fabric topology to function correctly, all Fabric members need to be in analyzer mode. This mode allows them to collect, analyze, and forward logs appropriately within the topology.

Conclusion:

The correct statements regarding the FortiAnalyzer Fabric topology are that logging devices must be registered to the supervisor and that Fabric members must be in analyzer mode.
