Understanding FortiAnalyzer Data Policy and Disk Utilization:

FortiAnalyzer uses data policies to manage log storage, retention, and disk utilization.

The Data Policy section indicates how long logs are kept for analytics and archive purposes.

The Disk Utilization section specifies the allocated disk space and the proportions used for analytics and archive, as well as when alerts should be triggered based on disk usage.

Analyzing the Provided Exhibit:

Keep Logs for Analytics:60 Days

Keep Logs for Archive:120 Days

Disk Allocation:300 GB (with a maximum of 441 GB available)

Analytics: Archive Ratio:30% : 70%

Alert and Delete When Usage Reaches:90%

Potential Problems Identification:

Disk Space Allocation:The allocated disk space is 300 GB out of a possible 441 GB, which might not be insufficient if the log volume is high, but it is not the primary concern based on the given data.

Analytics-to-Archive Ratio:The ratio of 30% for analytics and 70% for archive is unconventional. Typically, a higher percentage is allocated for analytics since real-time or recent data analysis is often prioritized. A common configuration might be a 70% analytics and 30% archive ratio. The misconfigured ratio can lead to insufficient space for analytics, causing issues with real-time monitoring and analysis.

Retention Periods:While the retention periods could be seen as lengthy, they are not necessarily indicative of a problem without knowing the specific log volume and compliance requirements. The length of these periods can vary based on organizational needs and legal requirements.

Conclusion:

Based on the analysis, the primary issue observed is theanalytics-to-archive ratiobeing misconfigured. This misconfiguration can significantly impact the effectiveness of the FortiAnalyzer in real-time log analysis, potentially leading to delayed threat detection and response.

NIST Cybersecurity Framework Overview:

The NIST Cybersecurity Framework provides a structured approach for managing and mitigating cybersecurity risks. Incident handling is divided into several phases to systematically address and resolve incidents.

Incident Handling Phases:

Preparation: Establishing and maintaining an incident response capability.

Detection and Analysis: Identifying and investigating suspicious activities to confirm an incident.

Containment, Eradication, and Recovery:

Containment: Limiting the impact of the incident.

Eradication: Removing the root cause of the incident.

Recovery: Restoring systems to normal operation.

Containment Phase:

The primary goal of the containment phase is to prevent the incident from spreading and causing further damage.

Quarantining a Compromised Host:

Quarantining involves isolating the compromised host from the rest of the network to prevent adversaries from moving laterally and causing more harm.

Techniques include network segmentation, disabling network interfaces, and applying access controls.

Understanding the MITRE ATT&CK Matrix:

The MITRE ATT&CK framework is a knowledge base of adversary tactics and techniques based on real-world observations.

Each tactic in the matrix represents the "why" of an attack technique, while each technique represents "how" an adversary achieves a tactic.

Analyzing the Provided Exhibit:

The exhibit shows part of the MITRE ATT&CK Enterprise matrix as displayed on FortiAnalyzer.

The focus is on technique T1071 (Application Layer Protocol), which has subtechniques labeled T1071.001, T1071.002, T1071.003, and T1071.004.

Each subtechnique specifies a different type of application layer protocol used for Command and Control (C2):

T1071.001 Web Protocols

T1071.002 File Transfer Protocols

T1071.003 Mail Protocols

T1071.004 DNS

Identifying Key Points:

Subtechniques under T1071:There are four subtechniques listed under the primary technique T1071, confirming that statement B is true.

Event Handlers for T1071:FortiAnalyzer includes event handlers for monitoring various tactics and techniques. The presence of event handlers for tactic T1071 suggests active monitoring and alerting for these specific subtechniques, confirming that statement C is true.

Misconceptions Clarified:

Statement A (four techniques under tactic T1071) is incorrect because T1071 is a single technique with four subtechniques.

Statement D (15 events associated with the tactic) is misleading. The number 15 refers to the techniques under the Application Layer Protocol, not directly related to the number of events.

Conclusion:

The accurate interpretation of the exhibit confirms that there are four subtechniques under technique T1071 and that there are event handlers covering tactic T1071.

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, andCREATE_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 theGET_EVENTSaction to use the FortiSandbox connector.

Step 4: Set up theRUN_REPORTandCREATE_INCIDENTactions based on the fetched events.

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.

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.

Understanding the Playbook and its Components:

The exhibit shows a playbook in which an event trigger starts actions upon detecting a malicious file.

The initial tasks in the playbook includeCREATE_INCIDENTandGET_EVENTS.

Analysis of Current Tasks:

EVENT_TRIGGER STARTER: This initiates the playbook when a specified event (malicious file detection) occurs.

CREATE_INCIDENT: This task likely creates a new incident in the incident management system for tracking and response.

GET_EVENTS: This task retrieves the event details related to the detected malicious file.

Objective of the Next Task:

The next logical step after creating an incident and retrieving event details is to update the incident with the event data, ensuring all relevant information is attached to the incident record.

This helps SOC analysts by consolidating all pertinent details within the incident record, facilitating efficient tracking and response.

Evaluating the Options:

Option A:Update Asset and Identityis not directly relevant to attaching event data to the incident.

Option B:Attach Data to Incidentsounds plausible but typically, updating an incident involves more comprehensive changes including status updates, adding comments, and other data modifications.

Option C:Run Reportis irrelevant in this context as the goal is to update the incident with event data.

Option D:Update Incidentis the most suitable action for incorporating event data into the existing incident record.

Conclusion:

The next task in the playbook should be to update the incident with the event data to ensure the incident reflects all necessary information for further investigation and response.

Fortinet Documentation on Playbook Creation and Incident Management.

Best Practices for Automating Incident Response in SOC Operations.

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.

Understanding Event Generation in FortiAnalyzer:

FortiAnalyzer generates events based on predefined rules and conditions to help in monitoring and responding to security incidents.

Analyzing the Options:

Option A:Data selectors filter logs based on specific criteria but do not generate events on their own.

Option B:Connectors facilitate integrations with other systems but do not generate events based on log matches.

Option C:Event handlers are configured with rules that define the conditions under which events are generated. When a log matches a rule in an event handler, FortiAnalyzer generates an event.

Option D:Tasks in playbooks execute actions based on predefined workflows but do not directly generate events based on log matches.

Conclusion:

FortiAnalyzer generates an event when a log matches a rule in an event handler.

Best Practices for Configuring Event Handlers in FortiAnalyzer.

Understanding the Playbook Configuration:

The playbook "FortiMail Sender Blocklist" is designed to manually input email addresses or IP addresses and add them to the FortiMail block list.

The playbook uses a FortiMail connector with the actionADD_SENDER_TO_BLOCKLIST.

Analyzing the Playbook Execution:

The configuration and actions provided show that the playbook is straightforward, starting with anON_DEMAND STARTERand proceeding to theADD_SENDER_TO_BLOCKLISTaction.

The action description indicates it is intended to block senders based on email addresses or domains.

Evaluating the Options:

Option A:UsingGET_EMAIL_STATISTICSis not required for the task of adding senders to a block list. This action retrieves email statistics and is unrelated to the block list configuration.

Option B:The primary reason for failure could be the requirement for a fully qualified domain name (FQDN). FortiMail typically expects precise information to ensure the correct entries are added to the block list.

Option C:The trust level of the client-side browser with FortiAnalyzer's self-signed certificate does not impact the execution of the playbook on FortiMail.

Option D:Incorrect connector credentials would result in an authentication error, but the problem described is more likely related to the format of the input data.

Conclusion:

The FortiMail Sender Blocklist playbook execution is failing because FortiMail is expecting a fully qualified domain name (FQDN).
