An enterprise needs to identify and block sophisticated application-layer threats while maintaining visibility into applications and users. Which device is best suited for this purpose?
Router with Access Control Lists (ACLs)
Traditional firewall
Next-generation firewall
Layer 2 switch
Next-generation firewalls are designed to inspect traffic at the application layer, providing deep packet inspection and the ability to identify and control applications regardless of port or protocol. They offer advanced threat detection and prevention capabilities, including blocking sophisticated application-layer threats while maintaining visibility into applications and users. Layer 2 switches operate at the data link layer and lack these security features. Routers with Access Control Lists (ACLs) can filter traffic based on IP addresses and ports but cannot inspect application-layer data. Traditional firewalls provide basic stateful packet inspection but do not offer the advanced application-layer visibility and control provided by next-generation firewalls.
