Information Security Concepts and Practices

The video tutorial explains the CIA Triad, a fundamental concept in IT security, focusing on confidentiality, integrity, and availability. Confidentiality involves protecting private information through encryption and access controls. Integrity ensures data accuracy and authenticity using hashing and digital signatures. Availability guarantees system uptime and reliability through fault tolerance and regular updates.
