Security is the state of being free from danger, threat, or fear, representing both an objective reality of safety and a subjective feeling of peace of mind. Because the term applies to almost every aspect of life, it is typically broken down into distinct, specialized fields. 🌐 Cybersecurity & Information Security
This field focuses on protecting digital assets, networks, and computer systems from unauthorized access, disruptions, or theft. It is largely built around the CIA Triad:
Confidentiality: Ensuring data is accessible only to authorized users.
Integrity: Guaranteeing that information is accurate and has not been altered maliciously.
Availability: Ensuring systems and data are reliable and accessible when needed.
