Fortinet NSE7_ADA-6.3 Dumps

The incident was auto cleared because within five minutes, the packet loss percentage dropped to a level where the host IP of the original rule matches the host IP of the clear condition pattern. The clear condition pattern specifies that if there is an event with a packet loss percentage less than or equal to 10% and a host IP that matches any host IP in this incident, then clear this incident.

The processes associated with Machine Learning/AI on FortiSIEM are phFortiInsightAI and phAnomaly. phFortiInsightAI is responsible for detecting anomalous user behavior using UEBA (User and Entity Behavior Analytics) techniques. phAnomaly is responsible for detecting anomalous network behavior using NTA (Network Traffic Analysis) techniques.

Tactic is what an attacker hopes to achieve in the MITRE ATT&CK framework. Tactic is a high-level category of adversary behavior that describes their objective or goal. For example, some tactics are Initial Access, Persistence, Lateral Movement, Exfiltration, etc. Each tactic consists of one or more techniques that describe how an attacker can accomplish that tactic.

The statements about collector communication with the FortiSIEM cluster that are true are:

• Collectors communicate periodically with the supervisor node. Collectors send heartbeat messages to the supervisor every 30 seconds to report their status and configuration.
• The supervisor periodically checks the health of the collector. The supervisor monitors the heartbeat messages from collectors and alerts if there is any issue with their connectivity or performance.
• Collectors upload event data to any node in the worker upload list, but report their health directly to the supervisor node. Collectors use a round-robin algorithm to distribute event data among worker nodes in the worker upload list, which is provided by the supervisor during registration. However, collectors only report their health and status to the supervisor node.

The windows agent is not delivering event logs correctly because the agent is unmanaged, meaning it is not assigned to any organization or customer. The supervisor will drop the logs silently from unmanaged agents, as they are not associated with any valid license or CMDB.

By default, the maximum number of event files stored on the collector in the event of a WAN link failure between the collector and the supervisor is 10.000. This value can be changed in the collector.properties file by modifying the parameter max_event_files_to_store. References: Fortinet NSE 7 - Advanced Analytics 6.3 Exam Description, page 13

 The SQLite databases that are used for the baselining are stored on Disk3 of the FortiSIEM server. Disk3 is also used for storing raw event data and CMDB data.

The rule filters events with an event type that belong to the Domain Account Locked CMDB group and a reporting IP that belong to the Domain Controller applications group. This means that only events that have both criteria met will be processed by this rule. The event type and reporting IP are joined by an AND operator, which requires both conditions to be true.

The syntax that will register a collector to the supervisor is phProvisionCollector --add . This command will initiate the registration process between the collector and the supervisor, and exchange certificates and configuration information. The parameter is the IP address of the supervisor node.

Reconnaissance and Discovery are two Tactics in the MITRE ATT&CK framework. Tactics are the high-level objectives of an adversary, such as initial access, persistence, lateral movement, etc. Reconnaissance is the tactic of gathering information about a target before launching an attack. Discovery is the tactic of exploring a compromised system or network to find information or assets of interest. References: Fortinet NSE 7 - Advanced Analytics 6.3 Exam Description, page 21
