Grasping the core security principles such as confidentiality, integrity, and availability is crucial for protecting data effectively. These principles are your arsenal in the quest for freedom in the digital realm. Confidentiality ensures that sensitive information remains private, safeguarding your data from prying eyes. This principle is about keeping secrets, ensuring that only those who should have access to information, do.

Integrity is your guarantee that the data you rely on is accurate and untampered. It’s about trust; knowing that the information you’re acting on hasn’t been altered in transit by malicious actors. This principle ensures that when you make decisions based on data, you’re standing on solid ground.

Availability ensures that the data you need is accessible when you need it, combating attempts to disrupt your access. It’s about ensuring that information is there for you, ready to be utilized to make informed decisions or take action without undue hindrance.

Incorporating a defense-in-depth approach, where multiple security measures are layered to protect data, ensures that even if one defense fails, others stand ready. This strategy is akin to having a series of fallback plans, ensuring your freedom to operate securely in an increasingly connected world.
