Cybersecurity is the practice of protecting systems, networks, and data from digital attacks, unauthorized access, damage, or theft. It involves a range of technologies, processes, and practices designed to safeguard information and ensure the confidentiality, integrity, and availability of data.

Key Concepts in Cybersecurity:

Confidentiality:
Ensuring that sensitive information is accessible only to those authorized to access it. Techniques like encryption, access controls, and authentication mechanisms are used to protect data confidentiality.
Integrity:
Ensuring that data is accurate, complete, and has not been tampered with or altered by unauthorized parties. Methods such as checksums, digital signatures, and hashing algorithms help maintain data integrity.
Availability:
Ensuring that data and systems are accessible when needed by authorized users. This involves protecting against disruptions from cyberattacks, hardware failures, or other issues that could affect access to data and services.
