NSE7_ADA-6.3 Fortinet NSE 7 - Advanced Analytics 6.3 Questions and Answers

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 incident from FortiSIEM shown in the exhibit is a brute force attack on a FortiGate device. The remediation option available to the administrator is to run the block IP FortiOS 5.4 action, which will block the source IP address of the attacker on the FortiGate device using a firewall policy.

The collector processes are responsible for receiving, parsing, normalizing, correlating, and monitoring events from various sources. The collector processes are phParser, phRuleMaster, and phMonitorAgent.

phRuleMaster is a process that performs rule evaluation and incident generation on FortiSIEM. phRuleMaster queues up the data being received from the phRuleWorkers into buckets based on time intervals, such as one minute, five minutes, or ten minutes. phRuleMaster is present on both the supervisor and workers nodes of a FortiSIEM cluster. phRuleMaster wakes up every 30 seconds to evaluate all the rule data in parallel using multiple threads.

FortiSIEM allows EPS bursting to handle event spikes without dropping events or violating the license agreement. EPS bursting means that FortiSIEM will let you burst up to five times the licensed EPS at any given time, provided it has accumulated enough unused EPS from previous time intervals.

 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.

To connect to a shared multi-tenant instance on FortiSOAR, the MSSP must install an agent node on the customer’s network. The agent node acts as a proxy between the customer’s devices and the FortiSOAR manager node. The agent node also performs data collection, enrichment, and normalization for the customer’s data sources. References: Fortinet NSE 7 - Advanced Analytics 6.3 Exam Description, page 11
