Understanding Data Encryption to Keep Customer Data Secure

Data encryption is crucial for protecting sensitive information, such as bank details, by encoding it with a key before transmission. This process ensures that only authorized parties with the correct key can decrypt and read the data. Without the key, the data remains incomprehensible. For example, using a Caesar Cipher with a shift of three can illustrate basic encryption. Cable Ties Ltd must employ data encryption for secure email transfers and adopt additional security measures to protect customer information. This leaflet offers essential advice for maintaining data security practices.
