The SSL protocol, also known as Secure Sockets Layer, addresses the confidentiality and integrity of a message through several methods:

1. Symmetric Encryption: This is a method of encryption where the same key is used for both encryption and decryption of the message. This ensures that the message remains confidential as only the sender and receiver have the key to decrypt it.

2. Message Authentication Code (MAC): This is a piece of information used to authenticate a message. It is generated by an algorithm that takes the message and a secret key as input. This ensures the integrity of the message as any changes to the message would result in a different MAC.

3. Hash Function: This is a function that takes an input and returns a fixed size string of bytes. The output is unique to the input, meaning any changes to the input would result in a different output. This is another way SSL ensures the integrity of a message.

4. Digital Signature Certificates: These are electronic documents that use a digital signature to bind together a public key with an identity. This allows the receiver of a message to verify the identity of the sender and ensure the message was not altered in transit.

So, all of the above-mentioned methods are used by the SSL protocol to address the confidentiality and integrity of a message.
