The UEBA agent status shows that it has been operationally down for one day and three hours ago (1d3h). This means that it has been down for 24 hours plus three hours, which is equal to 21 hours.

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.

The disadvantage of automatic remediation is that it can make a disruptive change to a user, block access to an application, or disconnect critical systems from the network. Automatic remediation can have unintended consequences if not carefully planned and tested. Therefore, it is recommended to use manual or semi-automatic remediation for sensitive or critical systems.

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

The device limit is a feature of the enterprise edition of FortiSIEM that restricts the number of devices that can be added to the system based on the license type. The device limit does not apply to the service provider edition, which allows unlimited devices per customer. The device limit is determined by the license type that was purchased from Fortinet, such as 100 devices, 500 devices, or unlimited devices.

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 rule evaluates multiple VPN logon failures within a ten-minute window. The rule will generate an incident if there are more than three VPN logon failures from the same source IP address within a ten-minute window. Based on the VPN failure events received within a ten-minute window, there are two incidents generated:

One incident for source IP address 10.10.10.10, which has four VPN logon failures at 09:01, 09:02, 09:03, and 09:04.

One incident for source IP address 10.10.10.11, which has four VPN logon failures at 09:06, 09:07, 09:08, and 09:09.

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.

You can empower SOC by deploying FortiSOAR in the following ways:

Collaborative knowledge sharing: FortiSOAR allows you to create and share playbooks, workflows, tasks, and notes among SOC analysts and teams. This enables faster and more consistent incident response and reduces duplication of efforts.

Reduce human error: FortiSOAR automates repetitive and tedious tasks, such as data collection, enrichment, analysis, and remediation. This reduces the risk of human error and improves efficiency and accuracy.

Address analyst skills gap: FortiSOAR provides a graphical user interface for creating and executing playbooks and workflows without requiring coding skills. This lowers the barrier for entry-level analysts and helps them learn from best practices and expert knowledge. References: Fortinet NSE 7 - Advanced Analytics 6.3 Exam Description, page 19
