Response 1
I defer with the reply that Point Tunneling Protocol (PPTP) provides no encryption capability. The reason as to why I defer with the response is because PPTP does allow multiprotocol traffic to be encrypted. It then encapsulates the encryptions in an IP header and then sends them to an IP network . On the other hand, I do agree with the statement provided in regards to L2TP which does use multiple protocols in supplying encryptions to the connection. It is also true that Secure Socket Tunneling Protocol (SSTP) uses Secure Socket Layer (SSL) in providing encryptions. I am in agreement that L2TP is replacing PPTP but the problem that arises is that L2TP only supports operating systems that are newer.
Response 2
I am in agreement with the reply that Network Access Protection (NAP) is a security platform that checks the health of a computer against a connection request, the method of connection, and health validator to make sure it will be allowed to access internal resources. The scenario provided in the reply is perfect since NAP would play a big part in securing connection as well as access in a company having mobile employees. The platform mainly protects other sources, that is, computers that are not entitled to the network and as such no external source apart from those authorised can be able to access the network or connection . NAP is therefore seen to be of great benefit for such a company due to the fact that computers that meet the requirements are the only ones given full access while those that do not are left out. The platform also checks at the health status of a computer before granting it access.
