Introduction
This chapter covers the third objective of Domain 3.0, Security Architecture of the CompTIA Security+ 701 exam.
It is essential to safeguard valuable information. In this chapter, we will consider this multifaceted challenge of data protection, which encompasses diverse data types such as regulated, trade secrets, and Intellectual Property (IP). These data classifications range from sensitive to critical, demanding varying levels of security. General data considerations add complexity, with data existing in different states (at rest, in transit, and in use) and concerns about data sovereignty and geolocation. To tackle these issues, organizations employ methods such as encryption, hashing, masking, and tokenization. They also restrict access based on geographic locations and permissions.
In the era of cyber-attacks, a tailored combination of these elements is key to robust data protection, ensuring that security aligns with an organization’s unique data profile...
