CISSP Hustle and Flow Study Corner: Confidentiality

In this first episode of "Study Corner," we dive deep into one of the core components of the CIA Triad—Confidentiality. This episode offers essential tips and strategies to help you prepare for the CISSP exam.   We start by discussing data classification, emphasizing the importance of categorizing information based on its sensitivity. You'll learn about the different levels of data—public, internal, and confidential—and how to apply the appropriate security measures for each.   Next, we explore encryption, breaking down the differences between symmetric and asymmetric methods. You'll gain insight into when to use AES for large data encryption versus RSA for secure key exchanges and smaller, sensitive tasks.   We then move into access control models, comparing Role-Based Access Control (RBAC), Discretionary Access Control (DAC), and Mandatory Access Control (MAC). Each model’s use is contextualized with practical examples to help you understand how permissions are managed in real-world scenarios.   By the end of this episode, you'll have actionable study tips and a clearer understanding of confidentiality principles in cybersecurity, helping you on your journey toward CISSP certification. I’m not yet CISSP certified. The goal here is to study and share the process of learning through various sources I’ve gathered, including official study materials, online resources, and even good old Google. I'm learning alongside you, and I'm not claiming to be an expert—just someone on the journey to becoming CISSP qualified.
