In this Discussion, you will explore IPsec, the most common network-layer security protocol, and consider what additional security measured might be needed beyond IPsec.
Submit an essay in which you share and value your own research findings on IPSec. Describe and analyse situations that require security mechanisms at layers above IP, despite the security provided by IPsec. List the roles of the application layer as it operates in the overall security scheme of the network.
