Data encryption is a process wherein plaintext data is converted into scrambled ciphertext using an encryption algorithm and an encryption key, which can subsequently be reverted to plaintext with a decryption key.
Tokenization disguises data values to appear as a non-sensitive values to threat actors. Also called data masking, tokenization links these placeholders, or tokens, back through to their sensitive counterparts.
Firewalls, in the traditional sense, secure data by managing network traffic between hosts and end systems to ensure complete data transfers. They allow or block traffic based on port and protocol and make decisions based on defined security policies.
