Technical Terms - Internet (A-Z) - IPsec

What does IPsec stand for?

• Internet Protocol Suite

• Internet Privacy System

• Internet Protocol Security

• Internal Protocol Security

Which protocol in the IPsec suite handles negotiations between two devices to decide authentication and encryption algorithms?

• Internet Protocol (IP)

• Internet Key Exchange (IKE)

• Authentication Header (AH)

• Encapsulating Secure Payload (ESP)

What does the Authentication Header (AH) protocol add to each data packet's header?

• Payload data

• Destination address

• Encryption key

• Authentication information

Which IPsec mode encrypts the entire IP packet and encapsulates it in a new packet?

• Encrypted Mode

• Transport Mode

• Tunnel Mode

• Secure Mode

What is the purpose of the Encapsulating Secure Payload (ESP) protocol in the IPsec suite?

• Handle negotiations between devices

• Add authentication information

• Create a new header

• Encrypt IP data packet

Which protocol in the IPsec suite encrypts only the contents of an IP packet, leaving the original header in place?

• Authentication Header (AH)

• Internet Key Exchange (IKE)

• Tunnel Mode

• Transport Mode

What is the main purpose of the Internet Key Exchange (IKE) protocol in IPsec?

• Encrypt IP data packet

• Create a new header

• Add authentication information

• Handle negotiations between devices

Which mode of IPsec is typically used for VPN connections and transferring packets over the public Internet?

• Secure Mode

• Transport Mode

• Tunnel Mode

• Encrypted Mode

What does the Encapsulating Secure Payload (ESP) protocol do to a normal IP data packet?

• Encrypts it using agreed-upon algorithm

• Adds authentication information

• Creates a new header

• Routes the packet to its destination

Which protocol in the IPsec suite adds header information that routes the packet to its destination?

• Internet Key Exchange (IKE)

• Authentication Header (AH)

• Encapsulating Secure Payload (ESP)

• Internet Protocol (IP)
