      • CIA Triad:

        • Confidentiality : deals with secrecy, restrict un authorized access

          • Security controls like encryption, access controls

          • Which security control we in placed to achieve this

            • Data encryption : data at rest

            • Hashing : data in transit (file integrity monitoring)

              • Sha 256

              • Sha 512

            • MFA (IAM and user access)

              • Privilege Access Management

              • Password rotations and policies

              • Secret Management

            • Physical Security

            • Default deny for critical data and infrastructure

              • Documented approval from leadership

              • Proper auditing/activity log management

    • Integrity : protecting reliability

      • Access restriction to make changes

      • Encryption policies to achieve integrity when data at rest

      • Hashing policies to achieve integrity when data at transit

    • Availability : having uninterrupted access

      • High availability of services or access to data.
