What are the best practices for testing and auditing your data encryption in transit and at rest?

Data at "rest" does not move across your network. It is stored data in your database. Data in "transit" moves across your network. It is data transferred from client to server and server to database.

Don't store sensitive data unless necessary. Data that isn't stored can't be hacked. Encrypt data both in transit and at rest using the most recent encryption algorithms.

Using secure storage solutions such as encrypted file systems, encrypted databases, or hardware security modules (HSMs) to protect data at rest from unauthorized access. when data at rest . Segmenting network into separate zones with different security levels and restrict access between them. This helps in containing potential breaches and minimizing the impact of unauthorized access to data in transit.

It is important to understand however not all SSL/TLS protocols are the same. SSL/TLS is an umbrella word that uses a wide variety of encryption algorithms called ciphers. Some ciphers are old and known to be vulnerable. It is important to pick the right ciphers when setting up a SSL/TLS certificate.

Data in transit moves across the internet and requires the most recent TLS 1.3 protocol for security. The TLS protocol is the successor to the legacy SSL. The TLS protocol implements AES 128 or 254-Bit encryption. The HTTP protocol plus TLS produces the secure HTTPS. Moreover, most web browsers will warn you against visiting unsecure HTTP sites. You have to see the lock near the domain name. This will indicate that data transfers are secure.

Data at rest is encrypted with AES 128 or 256 bit. The 256-bit encryption is chosen for its longer key length and can stand against brute force attacks. AES can encrypt larger amounts of data while RSA encrypts smaller amounts of data and therefore are used to produce key pairs. These key pairs are used to encrypt and decrypt data.

One major consideration when doing encryption is to determine how you would manage the keys. The locks (encryption algorithms) can be very secure, but if the key is not managed properly you will not have an effective encryption system.

SSLEmploys both asymmetric and symmetric encryption. Asymmetric encryption is used to create a secure session between a server and the client, while symmetric encryption transfers information within the secure session.

I recommend any new applications to strongly consider using a hosted cloud service for sensitive data and key management since they already have extensive audit and compliance tooling build-in for free. This stuff is not easy to do.
