Fortinet FCSS_EFW_AD-7.4 Exam Dumps

When multiple remote sites connect to the same hub using overlapping subnets, FortiGate needs to determine which route should be used for traffic forwarding. The route-overlap setting in IPsec Phase 2 allows FortiGate to handle this scenario by deciding whether to keep the existing route (use-old) or replace it with a new route (use-new).

In an ECMP (Equal-Cost Multi-Path) routing setup, both routes should be retained and balanced, but FortiGate does not support ECMP directly over overlapping routes in IPsec Phase 2. Instead, an administrator must decide which connection takes precedence using route-overlap settings.

False positives in Intrusion Prevention System (IPS) analysis can disrupt legitimate traffic and negatively impact user experience. To reduce false positives while maintaining security, administrators can:

Use IPS profile extensions to fine-tune the settings based on the organization's environment.

Select the correct operating system, protocol, and application types to ensure that IPS signatures match the network's actual traffic patterns, reducing false positives.

Customize signature selection based on the network's specific services, filtering out unnecessary or irrelevant signatures.

When configuring ADVPN (Auto-Discovery VPN) to connect overlay networks across different hubs using IBGP and EBGP, special configurations are required to allow spokes from different overlay networks to dynamically establish tunnels.

set auto-discovery-crossover enable

This allows cross-hub tunnel discovery in an ADVPN deployment where multiple hubs are used.

Since Hub A and Hub B belong to different overlays, enabling crossover discovery ensures that spokes from one overlay can dynamically create direct tunnels to spokes in the other overlay when needed.

set enforce-multihop enable

This setting ensures that BGP peers using loopback interfaces can establish connectivity even if they are not directly connected.

Multihop BGP sessions are required when using loopback addresses as BGP peer sources because the connection might need to traverse multiple routers before reaching the BGP neighbor.

This is especially useful in ADVPN deployments with multiple hubs, where routes might need to cross from one hub to another.

The best way to block outdated SSL/TLS versions is to configure the SSL/SSH inspection profile to enforce a minimum SSL/TLS version and disable weak SSL versions.

By setting the minimum allowed SSL version in the HTTPS settings of the SSL/SSH inspection profile, FortiGate will:

Block any connection using outdated SSL/TLS versions (such as SSLv3, TLS 1.0, or TLS 1.1).

Enforce secure communication using only strong SSL/TLS versions (such as TLS 1.2 or TLS 1.3).

Protect users from man-in-the-middle (MITM) and downgrade attacks that exploit weak encryption.

FortiGate's IPS protocol decoders analyze network transmission patterns and application signatures to identify and block malicious traffic. Application Control is the feature that allows FortiGate to detect, classify, and block applications based on their behavior and signatures, even when they do not rely on traditional URLs.

Application Control works alongside IPS protocol decoders to inspect packet payloads and enforce security policies based on recognized application behaviors.

It enables granular control over non-URL-based applications such as P2P traffic, VoIP, messaging apps, and other non-web-based protocols that IPS can identify through protocol decoders.

IPS and Application Control together can detect evasive or encrypted applications that might bypass traditional firewall rules.
