Question

IPsec provides encryption for traffic between devices.You would like to implement a solution that can scan the contents of the encrypted traffic to prevent any malicious attacks.Which solution should you implement?answerNetwork-based IDSPort scannerProtocol analyzerVPN concentratorHost-based IDS
Solution
The solution you should implement is a Network-based IDS. This is because a Network-based Intrusion Detection System (IDS) can analyze network traffic and identify suspicious activity. While IPsec provides encryption between devices, a Network-based IDS can still monitor and analyze the traffic for potential threats. Other options like Port scanner, Protocol analyzer, VPN concentrator, and Host-based IDS are not suitable for this specific scenario. A Port scanner is used for identifying open ports and services available on a network host. A Protocol analyzer is used for capturing and analyzing traffic on the network. A VPN concentrator primarily adds the capabilities of a VPN router. It provides the ability to create and manage VPN connections. A Host-based IDS, on the other hand, is used to monitor and analyze the internals of a computing system. It can also be used to monitor network traffic, but it is more focused on the activities within the host itself.
