_____ is a set of protocols developed by the IETF to support the secure exchange of packets
IPSec
IPSec has 2 encryption modes
transport and tunnel
this mode works by encrypting the data in each packet but leaves the header unencrypted. this means that the source and the destination addresses as well as other header information are not encrypted.
Transport Mode
This mode encrypts both the header and the data. Its more secure then transport, but can be slower
tunnel mode
this is used in setting up security associations in IPSec
Internet key exchange IKE
