Summary
We covered key topics in data security and privacy in this chapter, including encryption techniques and access control mechanisms such as authentication and authorization. We also emphasized how important routine maintenance and system updates are for protecting data. Examples from the real world were given to help the data engineer understand these concepts.
As we proceed to the last chapter, we’ll put your knowledge of these subjects to the test with a new set of interview questions, preparing you for both real-world problems and interviews.
