Protecting Sensitive Data at Rest
Implement encryption strategies for data stored in databases, file systems, and other storage mediums to prevent data breaches.
Data At Rest: What & Why?
Welcome to protecting sensitive data! In this lesson, we'll focus on data at rest. This refers to data that is stored physically, like on a hard drive, in a database, or on a backup tape.
Think of it as data that's 'sitting still' rather than moving across a network. It's a prime target for attackers if not properly secured.
Encryption: Our Digital Shield
The primary method for protecting data at rest is encryption. Encryption transforms data into an unreadable format, called ciphertext, using a secret key.
Only someone with the correct key can decrypt the data back into its original, readable form (plaintext). It's like locking your valuable information in a safe!
