Question No. 1

Refer to the exhibit.

The service provider deployed FortiSIEM without a collector and added three customers on the supervisor.

What mistake did the administrator make?

ACustomer A and customer B have overlapping IP addresses.

BCollectors must be deployed on all customer premises before they are added to organizations on the supervisor.

CThe number of workers on the FortiSIEM cluster must match the number of customers added.

DAt least one collector must be deployed to collect logs from service provider infrastructure devices.

Show Answer

Correct Answer: A

The mistake that the administrator made is that customer A and customer B have overlapping IP addresses. This will cause confusion and errors in event collection and correlation, as well as CMDB discovery and classification. To avoid this problem, each customer should have a unique IP address range or use NAT to translate their IP addresses.

Question No. 2

What is Tactic in the MITRE ATT&CK framework?

ATactic is how an attacker plans to execute the attack

BTactic is what an attacker hopes to achieve

CTactic is the tool that the attacker uses to compromise a system

DTactic is a specific implementation of the technique

Show Answer

Correct Answer: B

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.

Question No. 3

What is the disadvantage of automatic remediation?

AIt can make a disruptive change to a user, block access to an application, or disconnect critical systems from the network.

BIt is equivalent to running an IPS in monitor-only mode --- watches but does not block.

CExternal threats or attacks detected by FortiSIEM will need user interaction to take action on an already overworked SOC team.

DThreat behaviors occurring during the night could take hours to respond to.

Show Answer

Correct Answer: A

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.

Question No. 4

Refer to the exhibit.

The rule evaluates multiple VPN logon failures within a ten-minute window. Consider the following VPN failure events received within a ten-minute window:

How many incidents are generated?

Show Answer

Correct Answer: B

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.

Question No. 5

Refer to the exhibit. Click on the calculator button.

The profile database contains CPU utilization values from day one. At midnight on the second day, the CPU utilization values from the daily database will be merged with the profile database.

In the profile database, in the Hour of Day column where 9 is the value, what will be the updated minimum, maximum, and average CPU utilization values?

AMin CPU Util=32.31, Max CPU Ucil=33.50 and AVG CPU Util=33.50

BMin CPU Util=32.31, Max CPU Ucil=33.50 and AVG CPU Util=32.67

CMin CPU Util=32.31, Max CPU Ucil=32.31 and AVG CPU Util=32.31

DMin CPU Util=33.50, Max CPU Ucil=33.50 and AVG CPU Util=33.50

Show Answer

Correct Answer: B

The profile database contains CPU utilization values from day one. At midnight on the second day, the CPU utilization values from the daily database will be merged with the profile database using a weighted average formula:

New value = (Old value x Old weight) + (New value x New weight) / (Old weight + New weight)

The weight is determined by the number of days in each database. In this case, the profile database has one day of data and the daily database has one day of data, so the weight is equal for both databases. Therefore, the formula simplifies to:

New value = (Old value + New value) / 2

In the profile database, in the Hour of Day column where 9 is the value, the updated minimum, maximum, and average CPU utilization values are:

Min CPU Util = (32.31 + 32.31) / 2 = 32.31 Max CPU Util = (33.50 + 33.50) / 2 = 33.50 AVG CPU Util = (32.67 + 32.67) / 2 = 32.67
