FCSS_ADA_AR-6.7 Exam Dumps : FCSS Advanced Analytics 6.7 Architect

From theFilterssection in the exhibit, we see:

1.Event Type IN EventTypes: Domain Account Locked

This means the rule will match events where the event type is classified under theDomain Account Lockedcategory.

2.Reporting IP IN Applications: Domain Controller

This means the rule is filtering for events where the reporting IP is classified under theDomain Controller applications group.

3.Logical Operator: AND

The filters are combined usingAND, meaning both conditions must be met for an event to match.

Since both conditions must be true, the rule is effectively filtering events where:

● Theevent typebelongs to theDomain Account Locked CMDB group

● Thereporting IPbelongs to theDomain Controller applications group

The rule triggers an incident when there are two or more VPN logon failures within a 10-minute window, grouped by Source IP, Reporting Device, Reporting IP, and User. Let's analyze the events:

Breakdown of Events:

1. Reporting IP: 1.1.1.1, Source IP: 2.2.2.2, Device: FortiGate, User: Sarah

2. Reporting IP: 1.1.1.1, Source IP: 2.2.2.2, Device: FortiGate, User: John

3. Reporting IP: 1.1.1.3, Source IP: 2.2.2.2, Device: FortiGate2, User: Tom

4. Reporting IP: 1.1.1.3, Source IP: 2.2.2.2, Device: FortiGate2, User: John

5. Reporting IP: 1.1.1.3, Source IP: 2.2.2.2, Device: FortiGate2, User: Sarah

6. Reporting IP: 1.1.1.1, Source IP: 2.2.2.2, Device: FortiGate, User: Tom

Now, applying the grouping criteria (Source IP, Reporting Device, Reporting IP, and User):

● Group 1: (1.1.1.1, 2.2.2.2, FortiGate, John) → 1 occurrence (not enough)

● Group 2: (1.1.1.1, 2.2.2.2, FortiGate, Sarah) → 1 occurrence (not enough)

● Group 3: (1.1.1.1, 2.2.2.2, FortiGate, Tom) → 2 occurrences (incident triggered)

● Group 4: (1.1.1.3, 2.2.2.2, FortiGate2, John) → 2 occurrences (incident triggered)

● Group 5: (1.1.1.3, 2.2.2.2, FortiGate2, Sarah) → 1 occurrence (not enough)

● Group 6: (1.1.1.3, 2.2.2.2, FortiGate2, Tom) → 1 occurrence (not enough)

Final Incident Count:

● One incident for Group 3 (Tom on FortiGate)

● One incident for Group 4 (John on FortiGate2)

FortiSIEM enforces a device limit based on licensing and system-wide constraintsto ensure proper resource allocation and performance management.

The device limit is determined by the purchased license.

● FortiSIEM licensing includes limits on thenumber of devicesthat can be monitored.

● Thelicense type(e.g.,Enterprise vs. Service Provider) defines themaximum number of devicessupported.

For Service Provider editions, the device limit applies system-wide and is shared across all customers.

● In anMSSP (Managed Security Service Provider) setup, the totaldevice limit applies across all customers, rather than being allocated individually.

● This allowsflexible resource allocationbased on customer needs.
