Question

Data encryption and decryption typically takes place at the:

1) Layer 5 of the OSI model
2) Presentation layer of the OSI model
3) Layer 7 of the OSI model
4) Data link layer of the OSI model

Answer 1

Data encryption and decryption typically takes place at the Presentation layer of the OSI model (Layer 6).

Step-by-step explanation:

Data encryption and decryption typically takes place at the Presentation layer of the OSI model (Layer 6). This layer is responsible for ensuring that data is properly formatted, encrypted, and authenticated for transmission. Examples of encryption and decryption protocols used at this layer include SSL (Secure Sockets Layer) and TLS (Transport Layer Security). These protocols ensure secure communication between network entities by encrypting and decrypting the data being transmitted.
