| Dynamic Host Configuration Protocol (DHCP) allows properly configured client computers to obtain IP addresses automatically from a DHCP server. This is done so that a network administrator does not have to manually configure IP addresses on all of the computers on the network individually. The DHCP server takes care of this task quickly and automatically. |
|
Definition
| DHCP sessions use a four‐step process known as DORA. The four steps are:
Discovery: The client computer broadcasts out to the network in order to find a DHCP server.
Offering: The DHCP server sends out a unicast “offering” of an IP address to the client computer.
Request: The client broadcasts to all servers that it has accepted the offer.
Acknowledge: The DHCP server sends a final unicast to the client, including the IP information that the client will use.

| Internet Protocol Security (IPsec) is a protocol within the TCP/IP suite that encrypts and authenticates IP packets. It is designed to secure any application traffic because it resides on the Network layer (or Internet layer as TCP/IP programmers refer to it). |
|
Definition
| There are three main protocols that IPsec uses to perform its necessary functions:
Security association (SA): This generates the encryption and authentication keys that are to be used by IPsec.
Authentication header (AH):
Encapsulating Security Payload (ESP): This provides the same services as AH but also provides confidentiality when sending data.
