Centralized Management with FortiManager: A Comprehensive Guide to Multi-Device Management

 

In the realm of network security, managing multiple devices can be a daunting task, especially as organizations scale and their security needs become more complex. Fortinet’s FortiManager offers a powerful solution for centralized management of FortiGate firewalls and other Fortinet devices, enabling administrators to streamline operations, enhance security, and improve visibility across their networks. This article provides a detailed overview of using FortiManager for multi-device management, including setup, configuration, best practices, and the benefits it brings to organizations.

What is FortiManager?

FortiManager is a centralized management platform designed to manage multiple Fortinet devices from a single console. It allows network administrators to configure, monitor, and maintain security policies across various devices efficiently. With features such as policy management, device provisioning, and real-time monitoring, FortiManager simplifies the complexities of managing a multi-device environment.

Key Features of FortiManager

1. Centralized Policy Management: Create and manage security policies that can be applied across multiple FortiGate devices simultaneously.

2. Automated Device Provisioning: Streamline the process of adding new devices to the network with automated provisioning tools.

3. Comprehensive Monitoring: Gain visibility into the status and performance of all managed devices through a unified dashboard.

4. Log Management: Collect and analyze logs from all connected devices for better incident response and compliance reporting.

5. Role-Based Access Control (RBAC): Define user roles and permissions to ensure that only authorized personnel can make changes to critical configurations.

Getting Started with FortiManager

Step 1: Initial Setup

1. Accessing FortiManager:

• Connect your computer to the same network as your FortiManager device.

• Open a web browser and enter the default IP address (usually 192.168.1.99).

• Log in using the default credentials (username: admin, password: blank).

2. Change Default Password:

• Immediately change the default password for security purposes.

3. Configure Network Settings:

• Navigate to System Settings > Network to configure the management interface IP address, gateway, and DNS settings according to your network requirements.

Step 2: Adding Devices

1. Device Discovery:

• Go to Device Manager in the FortiManager interface.

• Click on “Add Device” and enter the IP address or hostname of the FortiGate device you want to manage.

• Provide the necessary credentials (admin username and password) for authentication.

2. Synchronizing Devices:

• After adding devices, synchronize them to ensure that configuration settings and policies are up-to-date.

• Select the device in Device Manager and click on “Retrieve Configuration” to pull current settings from the FortiGate.

Step 3: Configuring ADOMs (Administrative Domains)

ADOMs are used in FortiManager to separate configurations for different customers or departments within an organization:

1. Creating ADOMs:

• Navigate to System Settings > ADOMs.

• Click “Create New” to set up a new ADOM.

• Assign a name and configure settings based on organizational needs.

2. Assigning Devices to ADOMs:

• Once ADOMs are created, assign devices by selecting them in Device Manager and moving them to the appropriate ADOM.

Step 4: Policy Management

1. Creating Policy Packages:

• In each ADOM, navigate to Policy & Objects > Policy Packages.

• Click “Create New” to define a new policy package that will contain firewall rules, IPS settings, web filtering policies, etc.

2. Defining Policies:

• Within each policy package, create specific firewall rules by specifying source/destination addresses, services, action (accept/deny), and logging options.

• Ensure that policies are organized logically for easy management.

3. Installing Policies on Devices:

• After configuring policies, select the relevant device(s) in Device Manager.

• Click “Install” to apply the new policy package to selected devices.

Best Practices for Using FortiManager

1. Regularly Update Firmware: Keep your FortiManager and managed devices updated with the latest firmware versions to benefit from security patches and new features.

2. Utilize Templates: Use configuration templates for consistent deployment across multiple devices. This reduces errors and ensures uniformity in settings.

3. Monitor Logs Frequently: Regularly review logs from managed devices for unusual activity or potential security incidents. This proactive approach helps in timely threat detection.

4. Implement Role-Based Access Control: Define user roles within FortiManager based on job responsibilities to limit access to critical configurations and sensitive data.

5. Backup Configurations: Regularly back up configurations of both FortiManager and managed devices to prevent data loss in case of hardware failure or misconfiguration.

6. Conduct Training Sessions: Ensure that your IT staff is well-trained on using FortiManager effectively by conducting regular training sessions or workshops.
