What data should be encrypted in database?
In broad terms, there are two types of data you should encrypt: personally identifiable information and confidential business intellectual property.
- Personally Identifiable Information (PII)
- Confidential Business & Intellectual Property.
Should data at rest be encrypted?
The encryption of data at rest should only include strong encryption methods such as AES or RSA. Encrypted data should remain encrypted when access controls such as usernames and password fail. Increasing encryption on multiple levels is recommended.
Does all data need to be encrypted?
“Encrypt everything to protect your data!” It’s common advice these days, with concerns about snooping and privacy reaching a fever pitch. But average computer users don’t really need to encrypt everything. More operating systems are including encryption by default, which is fine.
How to encrypt user data in a database?
You can use a key derivation function to convert the user’s password into an encryption key. Then you would use a cryptographically secure pseudorandom number generator to generate a separate key that would encrypt the user’s data. You would then use the derived key to encrypt the generated key.
Where are encryption keys stored in a database?
The resulting ciphertext of the data encryption key could then be stored safely in the user table of your database (call the field “encryptedkey” if you like). In this way, the user’s password will become the means to decrypt the user’s encrypted key.
Why do you need to store encrypted user data?
The key that actually encrypts the data is only decrypted long enough to decrypt the data that it encrypted. You’ll need to store that key in the session in order to avoid the need to ask the user for his password on each decryption occurance.
Where are column master keys for always encrypted stored?
A column master key for Always Encrypted can be stored in a key store that implements the Cryptography API (CAPI). Typically, such a store is a hardware security module (HSM) – a physical device that safeguards and manages digital keys and provides crypto-processing.
