Understanding encryption
- [Instructor] Cryptography is one of the most important controls available to information security professionals. Encryption protects sensitive information from unauthorized disclosure in many different environments, and many other security functions depend upon cryptography. As we move to the cloud, encryption becomes even more important as a security control for two reasons. First, we use encryption to protect data in transit. That's data being sent over a network. This might be data traveling back and forth between an organization's work sites and the cloud or between the organization and our customers or partners. When data is moving over a network, it's especially vulnerable to eavesdropping threats, and encryption serves as a strong control against those threats. Second, we use encryption to protect data at rest. That's data when it's stored in any location. When it comes to cloud computing, encrypting the data that…
