Common Use Cases for Cryptography
In the Security+ exam, the use case just means examples of when something is used. We are now going to look at examples of when different cryptography techniques are used.
Supporting Confidentiality
A company's data cannot be priced, and the disclosure of this data could cause grave danger to the company. If your competitors steal your secrets, they could beat you to the market and you would not get the rewards that you deserved. To prevent data from being accessed, we will encrypt the data to prevent it from being viewed and prevent any protocol analyzer from reading the packets. When people access the company's network from a remote location, they should use an L2TP/IPSec VPN tunnel, using AES as the encryption method to create a secure tunnel across the internet and to prevent man-in-the-middle attacks. Encryption could be coupled with mandatory access control to ensure that data is secure and kept confidential.
