Fortinet FCSS_EFW_AD-7.4 Exam With Confidence Using Practice Dumps

FortiGate, like other security appliances, cannot analyze encrypted HTTPS traffic unless itdecryptsit first. Ifonly certificate inspectionis enabled, FortiGate can see the certificate details (such as the domain and issuer) butcannot inspect the actual web content.

To fully analyze the traffic and detect potential malware threats:

●Full SSL inspection (Deep Packet Inspection)must be enabled in theSSL/SSH Inspection Profile.

● This allows FortiGate todecrypt the HTTPS traffic, inspect the content, and then re-encrypt it before forwarding it to the user.

● Without full SSL inspection, threats embedded in encrypted traffic may go undetected.

When designing anADVPN (Auto-Discovery VPN) networkfor alarge enterprisewith spokes that havevarying numbers of internet links, the main challenge is tominimize the number of peer connections and routesat the hub while maintainingscalability and efficiency.

Using a dynamic routing protocol (such as BGP or OSPF) with loopback interfaces helps in several ways:

●Reduces the number of peer connectionsat the hub byusing a single loopback address per spokeinstead of individual physical interfaces.

●Enables simplified route advertisementby dynamically learning and propagating routes instead of manually configuring static routes.

●Supports multiple internet links per spokeefficiently, as dynamic routing can automatically adjust to the best available path.

●Allows seamless failoverif a spoke’s internet link fails, ensuring continuous connectivity.

ThisIPsec Phase 1 configurationdefines adynamicVPN tunnel that can accept connections from multiple peers. The settings chosen here suggest a configuration optimized fornetworks with intermittent traffic patternswhile ensuring resources are used efficiently.

Key configurations and their impact:

●set type dynamic→ This allows multiple peers to establish connections dynamically without needing predefined IP addresses.

●set ike-version 2→ UsesIKEv2, which is more efficient and supports features like EAP authentication and reduced rekeying overhead.

●set dpd on-idle→ Dead Peer Detection (DPD) is triggeredonly when the tunnel is idle, reducing unnecessary keep-alive packets and improving resource utilization.

●set add-route enable→ FortiGate automatically adds the route to the routing table when the tunnel is established, ensuring connectivity when needed.

●set proposal aes128-sha256 aes256-sha256→ Uses strong encryption and hashing algorithms, ensuring a secure connection.

●set keylife 28800→ Sets alonger key lifetime(8 hours), reducing the frequency of rekeying, which is beneficial for stable connections.

BecauseDPD is set to on-idle, the tunnel will not constantly send keep-alive messages but will still ensure connectivity when traffic is detected. This makes the configuration ideal fornetworks with regular but non-continuous traffic, balancing security and resource efficiency.
