What service does Authentication Header (AH) provide?
Integrity and authentication services
Which protocol provides combined encryption and authentication services in IPsec?
Encapsulating Security Payload (ESP)
Which function does IPsec key management perform?
Put in place any cryptographic keys required for services
What does ESP tunnel Security Association (SA) provide in IPsec?
Confidentiality protection for the IP packet's entire contents
What is the primary purpose of AH transport Security Association (SA) in IPsec?
Authenticate the sender of the IP packet
In IPsec, what role does the Encapsulating Security Payload (ESP) play?
Providing confidentiality and integrity services for IP traffic
What is the advantage of using authentication before encryption in IPsec?
Prevents anyone from intercepting and altering the authentication data without detection
In the context of IPsec key management, how many keys are typically required for communication between two applications?
Four pairs - transmit and receive keys for integrity and confidentiality
Why might using authentication before encryption be preferable in IPsec?
To prevent message interception and tampering without detection
What is the purpose of having an inner AH transport SA and an outer ESP tunnel SA in a bundle?
To allow for storing authentication information at the destination
How does ESP SA function when used without its authentication option?
Applies encryption to the IP payload without authentication
Which aspect of IPsec key management involves determining and distributing secret keys?
Key management
What is the main difference between manual and automated key management in IPsec?
Manual key management requires less administrative effort, while automated key management enables on-demand key creation.
