Collectors and Analyzers

This topic describes how to configure two FortiAnalyzer units as the Analyzer and Collector and make them work together. In the scenario shown in the diagram below, Company A has a remote branch network with a FortiGate unit and a FortiAnalyzer 400E in Collector mode. In its head office, Company A has another FortiGate unit and a

FortiAnalyzer 3000D in Analyzer mode. The Collector forwards the logs of the FortiGate unit in the remote branch to the Analyzer in the head office for data analysis and reports generation. The Collector is also used for log archival.

For related concepts, see Two operation modes on page 19 and Analyzer–Collector collaboration on page 21. You need to complete the initial setup for your FortiAnalyzer units first. See Initial setup on page 16.

Configuring the Collector

To configure the Collector:

1. Ensure the FortiAnalyzer Operation Mode is Collector. See Configuring the operation mode on page 161.
2. Check and configure the storage policy for the Collector. See Log storage information on page 57.

For the Collector, you should allocate most of the disk space for Archive logs. You should keep the Archive logs long enough to meet the regulatory requirements of your organization. After this initial configuration, you can monitor the storage usage and adjust it as you go.

Collectors and Analyzers

Following is a storage configuration example of the Collector.

3. Set up log forwarding to enable the Collector to forward the logs to the Analyzer. See Log Forwarding on page 190.

In particular,

l Set Remote ServerType to FortiAnalyzer. l Set ServerIP to the IP address of the Analyzer that this Collector will forward logs to. l Click Select Device and select the FortiGate device that the Collector will forward logs for.

Configuring the Analyzer

To configure the Analyzer:

1. Ensure the FortiAnalyzer Operation Mode is Analyzer. See Configuring the operation mode on page 161
2. Check and configure the storage policy for the Analyzer. See Log storage information on page 57.

Collectors and Analyzers

3. Make sure that the aggregation service is enabled on the Analyzer. If not, use this CLI command to enable it:

config system log-forward-service set accept-aggregation enable

end

4. Add the FortiGate device of the remote office that the Collector will forward logs for. See Authorizing devices on page 26.

Once the FortiGate of the remote office is added, the Analyzer starts receiving its logs from the Collector.

Fetching logs from the Collector to the Analyzer

At times, you might want to fetch logs from the Collector to the Analyzer. The Collector will perform the role of the fetch server, and the Analyzer will perform the role of fetch client. For information about how to conduct log fetching, see Fetcher Management on page 195.

 

High Availability

A FortiAnalyzer high availability (HA) cluster provides the following features:

• Provide real-time redundancy in case a FortiAnalyzer primary unit fails. If the primary unit fails, another unit in the cluster is selected as the primary unit. See If the primary unit fails on page 254.
• Synchronize logs and data securely among multiple FortiAnalyzer units. Some system and configuration settings are also synchronized. See Configuration synchronization on page 253. l Alleviate the load on the primary unit by using backup units for processes such as running reports.

A FortiAnalyzer HA cluster can have a maximum of four units: one primary or master unit with up to three backup or slave units. All units in the cluster must be of the same FortiAnalyzer series. All units are visible on the network.

All units must run in the same operation mode: Analyzer or Collector.

Configuring HA options

To configure HA options go to System Settings > HA and configure FortiAnalyzer units to create an HA cluster or change cluster configuration.

In System Settings > HA, use the ClusterSettings pane to create or change HA configuration, and use the Cluster Status pane to monitor HA status.

To configure a cluster, set the Operation Mode of the primary unit to High Availability. Then add the IP addresses and serial numbers of each backup unit to primary unit peer list. The IP address and serial number of the primary unit and all backup units must be added to each backup unit’s HA configuration. The primary unit and all backup units must have the same Group Name, Group ID and Password.

You can connect to the primary unit GUI to work with FortiAnalyzer. Using configuration synchronization, you can configure and work with the cluster in the same way as you work with a standalone FortiAnalyzer unit.

Configure the following settings:

Cluster Status
Operation Mode	Select High Availability to configure the FortiAnalyzer unit for HA. Select Standalone to stop operating in HA mode.
Preferred Role	Select the preferred role when this unit first joins the HA cluster. If the preferred role is Master, then this unit becomes the primary unit if it is configured first in a new HA cluster. If there is an existing primary unit, then this unit becomes a backup (slave) unit. The default is Slave so that the unit can synchronize with the primary unit. A slave or backup unit cannot become a master or primary unit until it is synchronized with the current primary unit.
Cluster Virtual IP
Interface	The interface the FortiAnalyzer HA unit uses to provide redundancy.
IP Address	The IP address for which the FortiAnalyzer HA unit is to provide redundancy.
Cluster Settings
Peer IP	Type the IP address of another FortiAnalyzer unit in the cluster.
Peer SN	Type the serial number of the FortiAnalyzer unit corresponding to the entered IP address.
Group Name	Type a group name that uniquely identifies the FortiAnalyzer HA cluster. All units in a cluster must have the same Group Name, Group ID and Password.
Group ID	Type a group ID from 1 to 255 that uniquely identifies the FortiAnalyzer HA cluster.
Password	A password for the HA cluster. All members of the HA cluster must have the same password.
Heart Beat Interval	The time the primary unit waits between sending heartbeat packets, in seconds. The heartbeat interval is also the amount of time that backup units waits before expecting to receive a heartbeat packet from the primary unit.
Priority	The priority or seniority of the backup unit in the cluster.
Log Data Sync	This option is on by default. It provides real-time log synchronization among cluster members.

Log synchronization

To ensure logs are synchronized among all HA units, FortiAnalyzer HA synchronizes logs in two states: initial logs synchronization and real-time log synchronization.

Initial Logs Sync

When you add a unit to an HA cluster, the primary unit synchronizes its logs with the new unit. After initial sync is complete, the backup unit automatically reboots. After the reboot, the backup unit rebuilds its log database with the synchronized logs.

You can see the status in the ClusterStatus pane Initial Logs Sync column.

Log Data Sync

After the initial log synchronization, the HA cluster goes into real-time log synchronization state.

Log Data Sync is turned on by default for all units in the HA cluster.

When Log Data Sync is turned on in the primary unit, the primary unit forwards logs in real-time to all backup units. This ensures that the logs in the primary and backup units are synchronized.

Log Data Sync is turned on by default in backup units so that if the primary unit fails, the backup unit selected to be the new primary unit will continue to synchronize logs with backup units.

If you want to use a FortiAnalyzer unit as a standby unit (not as a backup unit), then you don’t need real-time log synchronization so you can turn off Log Data Sync.

Configuration synchronization

Configuration synchronization provides redundancy and load balancing among the cluster units. A FortiAnalyzer HA cluster synchronizes the configuration of the following modules to all cluster units: l Device Manager l Incidents & Events l Reports l Most System Settings

FortiAnalyzer HA synchronizes most System Settings in the HA cluster. The following table shows which System Setting configurations are synchronized:

System Setting	Configuration synchronized
Dashboard > System Information	Only Administrative Domain is synchronized. All other settings in the System Information widget are not synchronized.
All ADOMs	Yes
Storage Info	Yes
Network	No
HA	No
Admin	Yes
Certificates > Local Certificates	No
Certificates > CA Certificates	Yes
Certificates > CRL	Yes
Log Forwarding	Yes
Fetcher Management	Yes
Event Log	No
Task Monitor	Yes
Advanced > SNMP	Yes
Advanced > Mail Server	Yes
Advanced > Syslog Server	Yes
Advanced > Meta Fields	Yes
Advanced > Device Log Settings	Yes
Advanced > File Management	Yes
Advanced > Advanced Settings	Yes

Monitoring HA status

In System Settings > HA, the ClusterStatus pane shows the HA status. This pane displays information about the role of each cluster unit, the HA status of the cluster, and the HA configuration of the cluster.

The ClusterStatus pane displays the following information:

Role	Role of each cluster member.
Serial Number	Serial number of each cluster member.
IP	IP address of each cluster members including the host.
Host Name	Host name of the HA cluster.
Uptime/Downtime	Uptime or downtime of each cluster member.
Initial Logs Sync	Status of the initial logs synchronization.
Configuration Sync	Status of synchronizing configuration data.
Message	Status or error messages, if any.

If the primary unit fails

If the primary or master unit becomes unavailable, another unit in the cluster is selected as the primary unit using the following rules:

• All cluster units are assigned a priority from 80 – 120. The default priority is 100. If the primary unit becomes unavailable, an available unit with the highest priority is selected as the new primary unit. For example, a unit with a priority of 110 is selected over a unit with a priority of 100.
• If multiple units have the same priority, the unit whose primary IP address has the greatest value is selected as the new primary unit. For example, 123.45.67.123 is selected over 123.45.67.124.
• If a new unit with a higher priority or a greater value IP address joins the cluster, the new unit does not replace (or preempt) the current primary unit.

If the FortiAnalyzer being replaced is the primary, after replacing it, use execute fgfm reclaim-dev-tunnel to force FortiGates to connect to the new FortiAnalyzer.

Load balancing

Because FortiAnalyzer HA synchronizes logs among HA units, the HA cluster can balance the load and improve overall responsiveness. Load balancing enhances the following modules:

• Reports
• SOC

When generating multiple reports, the loads are distributed to all HA cluster units in a round-robin fashion. When a report is generated, the report is synchronized with other units so that the report is visible on all HA units.

Similarly, for SOC, cluster units share some of the load when these modules generate output for their widgets.

Upgrading the FortiAnalyzer firmware for an operating cluster

You can upgrade the firmware of an operating FortiAnalyzer cluster in the same way as upgrading the firmware of a standalone FortiAnalyzer unit.

Upgrade the backup units first. Upgrade the primary (master) unit last, after all backup units have been upgraded and have synchronized with the primary unit. When you upgrade the primary unit, one of the backup units is automatically selected to be the primary unit following the rules you set up in If the primary unit fails on page 254. This allows the HA cluster to continue operating through the upgrade process with primary and backup units.

During the upgrade, you might see messages about firmware version mismatch. This is to be expected. When the upgrade is completed and all cluster members are at the same firmware version, you should not see this message.

To upgrade FortiAnalyzer HA cluster firmware:

1. Log into each backup unit and upgrade the firmware.

See the FortiAnalyzerRelease Notes and FortiAnalyzerUpgrade Guide in the Fortinet Document Library for more information.

2. Wait for the upgrades to complete and check that the backup units have joined the HA cluster as slaves.
3. Ensure that logs are synchronized with the primary unit.
4. Upgrade the primary (master) unit.

When the primary unit is upgraded, it automatically becomes a backup unit and one of the backup units is automatically selected to be the primary unit following the rules you set up in If the primary unit fails on page 254.

This allows the HA cluster to continue operating through the upgrade process with primary and backup units.

 

Two-factor authentication

To configure two-factor authentication for administrators you will need the following:

l FortiAnalyzer l FortiAuthenticator l FortiToken

GUI language

The GUI supports multiple languages, including:

l English l Simplified Chinese l Spanish l Traditional Chinese l Japanese l Korean

By default, the GUI language is set to Auto Detect, which automatically uses the language used by the management computer. If that language is not supported, the GUI defaults to English. For best results, you should select the language used by the operating system on the management computer.

For more information about language support, see the FortiAnalyzerRelease Notes.

To change the GUI language:

1. Go to System Settings > Admin > Admin Settings.
2. Under the View Settings, In the Language field, select a language, or Auto Detect, from the dropdown list.
3. Click Apply to apply the language change.

Idle timeout

To ensure security, the idle timeout period should be short. By default, administrative sessions are disconnected if no activity takes place for five minutes. This idle timeout is recommended to prevent anyone from using the GUI on a PC that was logged in to the GUI and then left unattended. The idle timeout period can be set from 1 to 480 minutes.

To change the idle timeout:

1. Go to System Settings > Admin > Admin Settings.
2. Change the Idle Timeout period as required.
3. Click Apply.

Password policy

You can enable and configure password policy for the FortiAnalyzer.

To configure the password policy:

1. Go to System Settings > Admin > Admin Settings.
2. Click to enable Password Policy.
3. Configure the following settings, then click Apply to apply to password policy.

Minimum Length	Specify the minimum number of characters that a password must be, from 8 to 32. Default: 8.
Must Contain	Specify the types of characters a password must contain: uppercase and lowercase letters, numbers, and/or special characters.
Admin Password Expires after	Specify the number of days a password is valid for. When the time expires, an administrator will be prompted to enter a new password.

Password lockout and retry attempts

By default, the number password retry attempts is set to three, allowing the administrator a maximum of three attempts at logging in to their account before they are locked out for a set amount of time (by default, 60 seconds).

The number of attempts and the default wait time before the administrator can try to enter a password again can be customized. Both settings can be configured using the CLI.

To configure the lockout duration:

1. Enter the following CLI commands:

config system global set admin-lockout-duration <seconds>

end

To configure the number of retry attempts:

1. Enter the following CLI commands:

config system global set admin-lockout-threshold <failed_attempts>

end

Example

To set the lockout threshold to one attempt and set a five minute duration before the administrator can try to log in again, enter the following CLI commands:

config system global set admin-lockout-duration 300 set admin-lockout-threshold 1

end

Global administration settings

The administration settings page provides options for configuring global settings for administrator access to the FortiAnalyzer device. Settings include:

• Ports for HTTPS and HTTP administrative access

To improve security, you can change the default port configurations for administrative connections to the FortiAnalyzer. When connecting to the FortiAnalyzer unit when the port has changed, the port must be included, such as https://<ip_address>:<port>. For example, if you are connecting to the FortiAnalyzer unit using port 8080, the URL would be https://192.168.1.99:8080. When you change to the default port number for HTTP, HTTPS, or SSH, ensure that the port number is unique.

• Idle timeout settings

By default, the GUI disconnects administrative sessions if no activity occurs for five minutes. This prevents someone from using the GUI if the management computer is left unattended.

• GUI language

The language the GUI uses. For best results, you should select the language used by the management computer. l GUI theme

The default color theme of the GUI is Blueberry. You can choose another color or an image. l Password policy

Enforce password policies for administrators.

To configure the administration settings:

1. Go to System Settings > Admin > Admin Settings.
2. Configure the following settings as needed, then click Apply to save your changes to all administrator accounts:

Administration Settings

HTTP Port	Enter the TCP port to be used for administrative HTTP access. Default: 80. Select Redirect to HTTPS to redirect HTTP traffic to HTTPS.
HTTPS Port	Enter the TCP port to be used for administrative HTTPS access. Default: 443.
HTTPS & Web Service Server Certificate	Select a certificate from the dropdown list.
Idle Timeout	Enter the number of minutes an administrative connection can be idle before the administrator must log in again, from 1 to 480 (8 hours). See Idle timeout on page 246 for more information.

Must Contain	Select the types of characters a password must contain.
Admin Password Expires after	Select the number of days a password is valid for, after which it must be changed.

SAML admin authentication

SAML can be enabled across all Security Fabric devices, enabling smooth movement between devices for the administrator. FortiAnalyzer can play the role of the identity provider (IdP) or the service provider (SP) when an external identity provider is available.

Devices configured to the IdP can be accessed through the Quick Access menu which appears in the top-right corner of the main menu. The current device is indicated with an asterisk (this feature is currently only supported in FAZ/FMG).

Logging into an SP device will redirect you to the IdP login page. By default, it is a Fortinet login page. After successful authentication, you can access other SP devices from within the same browser without additional authentication.

1. Go to System Settings > SAML SSO.
2. Select Identity Provider(IdP).
3. In the IdP Certificate dropdown, choose a certificate where IdP is used.
4. Select Download to get the IdP certificate, used later to configure SPs.
5. Select Apply.
6. In the SP Settings table, select Create to add a service provider.
7. In the Edit Service Provider window: l Enter a name for the SP.
   • Select Fortinet as the SP Type.
   • If the SP is not a Fortinet product, select Custom as the SP Type and copy the SP Entity ID, SP ACS (Login) URL, and SP SLS (Logout) URL from your SPs configuration page.
   • Enter the SP IP address.
   • Copy down the IdP Prefix. It is required when configuring SPs.
8. Select OK.
9. A custom login page can be created by moving the Login Page Template toggle to the On position and selecting Customize.

To configure FortiAnalyzer as a service provider:

1. Go to System Settings > SAML SSO.
2. Select Service Provider(SP).
3. Select Fortinet as the IdP Type.
4. Enter the IdP IP address and the IdP prefix that you obtained while configuring the IdP device.
5. Select the IdP certificate.

If this is a first-time set up, you can import the IdP certificate that you downloaded while configuring the IdP device.

6. Confirm that the information is correct and select Apply.
7. Repeat the steps for each FAZ/FMG that is to be set as a service provider.
