1. Process Monitoring in FortiSIEM: FortiSIEM can monitor critical processes on managed devices, such as an SMTP process on a Linux server. 2. Event Generation: When a critical process stops, FortiSIEM generates an event to alert administrators. 3. Event Types: Specific event types correspond to different monitored conditions. For a stopped process, the event type PH_DEV_MON_PROC_STOP is used. 4. Reasoning: The name PH_DEV_MON_PROC_STOP (Device Monitoring Process Stop) is a generic event type used by FortiSIEM to indicate that any monitored process, including SMTP, has stopped. 

1. Feature Overview: FortiSIEM provides several tools for querying and reporting on device information within an environment. 2. Inventory Tab: The Inventory tab is specifically designed to display detailed information about devices, including their firmware versions. 3. Query Functionality: Within the Inventory tab, you can run queries to filter and display devices based on specific attributes, such as the firmware version for FortiGate devices. 4. Report Generation: By running a query in the Inventory tab, you can produce a report that lists the FortiGate devices and their corresponding firmware versions. 

1. Threshold Management: FortiSIEM uses thresholds to generate alerts and incidents based on performance and security metrics. 2. Global Thresholds: These are default thresholds applied to all devices and metrics across the system, providing a baseline for alerts. 3. Per Device Thresholds: These thresholds can be customized for individual devices, allowing for more granular control and tailored monitoring based on specific device characteristics and requirements. 4. Usage in Performance Metrics: Both global and per device thresholds are used for performance metrics to ensure comprehensive and precise monitoring. 

1. Rule Notifications and Automated Remediation: In FortiSIEM, notifications and automated remediation actions can be configured to respond to specific incidents or alerts generated by rules. 2. Notification Policy: This is the section where administrators configure the settings for notifications and specify the actions to be taken when a rule triggers an alert. 3. Configuration Options: Includes defining the recipients of notifications, the type of notifications (e.g., email, SMS), and any automated remediation actions that should be executed. 4. Importance: Proper configuration of notification policies ensures timely alerts and automated responses to incidents, enhancing the effectiveness of the SIEM system. 

1. Incident Categories in FortiSIEM: Incidents in FortiSIEM are categorized to help administrators quickly identify and prioritize the type of issue. 2. Four Main Categories: - Performance: Incidents related to the performance of devices and applications, such as high CPU usage or memory utilization. - Availability: Incidents affecting the availability of services or devices, such as downtime or connectivity issues. - Security: Incidents related to security events, such as failed login attempts, malware detection, or unauthorized access. - Change: Incidents triggered by changes in the configuration or state of devices, such as new software installations or configuration modifications. 3. Importance of Categorization: These categories help in the efficient management and response to different types of incidents, allowing for better resource allocation and quicker resolution. 

1. WMI Method: Windows Management Instrumentation (WMI) is a set of specifications from Microsoft for consolidating the management of devices and applications in a network. 2. Log Collection: WMI is used to collect various types of logs from Windows devices. - Security Logs: Contains records of security-related events such as login attempts and resource access. - Application Logs: Contains logs generated by applications running on the system. - System Logs: Contains logs related to the operating system and its components. 3. Comprehensive Data Collection: By using WMI, FortiSIEM can gather a wide range of event logs that are crucial for monitoring and analyzing the security and performance of Windows devices. 

1. Component Roles in FortiSIEM: Different components in FortiSIEM have specific roles and responsibilities, which contribute to the overall performance and functionality of the system. 2. Query Worker: The query worker component is specifically designed to handle and optimize search queries within FortiSIEM. 3. Function: It processes search requests and executes analytic searches efficiently, handling large volumes of data to provide quick results. 4. Optimization: By improving the efficiency of query execution, the query worker can significantly speed up long, ad hoc analytic searches, addressing performance issues. 5. Performance Impact: Utilizing the query worker ensures that searches are handled by a component optimized for such tasks, reducing the load on other components and improving overall system performance. 

1. Rules Engine in FortiSIEM: The rules engine evaluates incoming events based on defined conditions to detect incidents and anomalies. 2. Aggregation Condition: The aggregation condition instructs FortiSIEM to summarize and count the matching evaluated data. 3. Function: Aggregation is used to group events based on specified criteria and then perform operations such as counting the number of occurrences within a defined time window. 4. Purpose: This allows for the detection of patterns and anomalies, such as a high number of failed login attempts within a short period. 

1. Incident Status in FortiSIEM: The status of an incident indicates its current state and helps administrators track and manage incidents effectively. 2. Cleared Status: When an incident's status is "Cleared," it means that a specific condition set to clear the incident has been satisfied. 3. Clear Condition: This is typically a predefined condition that indicates the issue causing the incident has been resolved or no longer exists. 4. Automatic vs. Manual Clearance: While some incidents may be cleared automatically based on clear conditions, others might be manually cleared by an operator. 

1. Enterprise Licensing Mode: In FortiSIEM enterprise licensing mode, collectors are deployed in remote sites to gather and forward data to the central FortiSIEM cluster located in the data center. 2. Collector Functionality: Collectors are responsible for receiving logs, events (e.g., syslog), and performance metrics from devices. 3. Link Down Scenario: When the link between the collector and the FortiSIEM cluster is down, the collector needs a mechanism to ensure no data is lost during the disconnection. 4. Event Buffering: The collector buffers the events locally until the connection is restored, ensuring that no incoming events are lost. This buffered data is then forwarded to the FortiSIEM cluster once the link is re-established. 

1. FortiSIEM Architecture: The FortiSIEM architecture includes several components such as Supervisors, Workers, Collectors, and Agents, each playing a distinct role in the SIEM ecosystem. 2. Real-Time Event Correlation: Real-time event correlation is a critical function that involves analyzing and correlating incoming events to detect patterns indicative of security incidents or operational issues. 3. Role of Supervisor and Worker: - Supervisor: The Supervisor oversees the entire FortiSIEM system, coordinating the processing and analysis of events. - Worker: Workers are responsible for processing and correlating the events received from Collectors and Agents. 4. Collaboration for Correlation: Together, the Supervisor and Worker components perform real-time event correlation by distributing the load and ensuring efficient processing of events to identify incidents in real-time.
