Fortigate Multiple Interface Policy

“Welcome to my channel! In this video, I will describe how to configure firewall policies with multiple source and destination interfaces in FortiGate. We’ll be looking at how to allow traffic between multiple interfaces on your FortiGate firewall, which is particularly useful when you have different subnets that you want to control traffic between or when you have multiple VLANs that need to communicate with each other. By the end of this video, you’ll have a better understanding of how to configure these policies in FortiGate and how they can help secure your network.

  1. Network Interfaces:
    • In a FortiGate device, you typically have multiple network interfaces, each connected to a different network segment or zone. These interfaces can be physical (Ethernet ports) or virtual (VLANs, subinterfaces, loopback interfaces, etc.).
  2. Traffic Flow:
    • Traffic flows between these interfaces as data packets are transmitted through the FortiGate device. Each interface represents a different security zone, and traffic between these zones must be controlled and inspected for security purposes.
  3. Security Policies:
    • FortiGate uses security policies to determine how traffic is treated as it passes between these interfaces. Security policies are rules that define the permitted actions for specific types of traffic. They include criteria like source and destination IP addresses, ports, protocols, and more.
  4. Multiple Interface Policy:
    • The “Multiple Interface Policy” feature in FortiGate allows you to create a single security policy that applies to traffic flowing between multiple interfaces or zones. This is especially useful when you want to define a consistent policy for a specific category of traffic across multiple interfaces.
  5. Use Cases:
    • There are several use cases for Multiple Interface Policies:
      • DMZ Configuration: If you have a DMZ zone with multiple servers that need different levels of access, you can create a single policy to control traffic from different internal zones to the DMZ.
      • Guest Network Isolation: You can use this feature to control traffic from the guest network to multiple internal networks with a single policy.
      • VPN Traffic: When you have multiple VPN tunnels terminating on different interfaces, you can create a policy that applies to traffic from all those tunnels.
  6. Policy Configuration:
    • When configuring a Multiple Interface Policy, you define the policy’s source and destination interfaces (security zones), specify the criteria for matching traffic (source/destination addresses, services, users, etc.), and define the action to take (allow, deny, NAT, etc.).
  7. Policy Order:
    • Policy order is important. FortiGate processes policies from top to bottom, and the first matching policy is applied. So, you should order your Multiple Interface Policies appropriately to ensure that more specific policies are evaluated before broader ones.
  8. Logging and Monitoring:
    • FortiGate provides extensive logging and monitoring capabilities, allowing you to track traffic as it traverses the different interfaces and the policies applied to it.
  9. Traffic Inspection:
    • Depending on your policy settings, FortiGate can perform various security functions like antivirus scanning, intrusion detection and prevention, content filtering, and more on the traffic as it flows between interfaces.

In summary, FortiGate Multiple Interface Policies are a crucial part of network security configuration. They enable you to manage and secure traffic between multiple network interfaces by defining specific security policies that dictate how traffic should be handled. This feature is particularly useful in complex network environments with diverse security requirements.

FortiGate Two Factor Authentication with Email

Hello everyone, in this video, I will introduce how you can set up 2-step verification for SSL VPN users by sending a token through email. By default, there is no way to enable this option via the graphical user interface. We must enable this feature from the CLI.

1. User Login Request:

  • When a user attempts to log in to a FortiGate-protected resource, such as a VPN, web portal, or firewall management interface, they provide their username and password as the first authentication factor.

2. Verification of Username and Password:

  • FortiGate first verifies the provided username and password against its user database or an external authentication source, such as LDAP, RADIUS, or Active Directory. If the credentials are valid, the user passes the first authentication factor.

3. Request for Second Authentication Factor:

  • Once the user successfully completes the first factor (username and password), FortiGate prompts the user for the second authentication factor. In this case, it’s an email-based authentication.

4. Email-Based Authentication:

  • FortiGate sends an email containing a one-time passcode (OTP) or a link to the user’s registered email address. This email typically includes instructions on what the user should do next.

5. Retrieving and Entering the OTP:

  • The user checks their email and retrieves the OTP or clicks on the provided link. The OTP is typically time-limited and can only be used once for security purposes.

6. Entering the OTP or Confirming Access:

  • The user enters the OTP from the email into the FortiGate login prompt or clicks on the link, which confirms their identity as the second authentication factor.

7. Verification of Second Factor:

  • FortiGate verifies the entered OTP or link against its records to ensure it matches the one it sent to the user’s email. If the OTP or link is valid and within the time window, the user passes the second authentication factor.

8. Access Granted:

  • Once both factors are successfully authenticated (username/password and email-based OTP/link), FortiGate grants the user access to the requested resource or system.

9. Continuous Monitoring:

  • FortiGate may also implement continuous monitoring and session management to ensure that user sessions remain secure throughout their usage.

It’s worth noting that while email-based 2FA is a common method, FortiGate also supports various other second-factor authentication methods, including SMS-based codes, hardware tokens, software tokens, and push notifications through mobile apps. The choice of the second-factor method can depend on the organization’s security policies and user preferences.

Implementing 2FA with email in FortiGate enhances security by adding an extra layer of authentication, making it more challenging for unauthorized users to gain access to critical resources and helping protect against unauthorized access and data breaches.
