How does encryption project the wireless network?

Integrity checks are designed to detect if data has been altered or tampered with during transit, providing data integrity, which is distinct from encryption's primary role of confidentiality.

While encryption uses ciphers, its main purpose is data confidentiality, not specifically the detection or prevention of zero-day network attacks, which often fall under intrusion detection/prevention systems.

Encryption employs a specific algorithm and a secret key to scramble wireless data packets, rendering them unintelligible to unauthorized parties. This process ensures that only devices possessing the correct key, typically the access point and the authenticated client, can decrypt and access the confidential information being transmitted over the wireless medium.

Encryption directly transforms data to protect confidentiality, whereas a policy defines rules for network access and communication, acting at a higher logical level.
