Encapsulation: attaches necessary protocol information to the data before network transmission. Unencapsulate: unseal data from a specific protocol header. Peer layer communication: each layer of the source sender's OSI model must communicate with the peer layer
CCNA Authentication-basic network knowledge-1-3 ensures confidentiality by allowing intended and authorized recipients (individuals, processes, or devices) to read data to maintain data privacy. Use a powerful user authentication system, a password that is difficult to guess, and frequent password changes to restrict access to stored data on communication and Internet devices. Encryption of content ensures
