Security based connection is provided by which layer?(a) Network layer

1.	Security based connection is provided by which layer?(a) Network layer(b) Session layer(c) Application layer(d) Transport layerThis question was posed to me in unit test.This intriguing question comes from Transport Layer in portion Internet Principles of IOT
Answer» The CORRECT choice is (d) Transport layer The best explanation: IOT is, of course all about connection to the internet. And even more so, it is about security. Without security and without ENCRYPTED communication, anyone can see what I SEND and receive. So encryption and secure communication are key. The solution is to use a connection that uses the TLS(Transport Layer Security) PROTOCOL.
