1. Explain the elements of the CIA Triad and give an example of each.  Confidentiality- concept of the measures used to ensure the protection of the protection of the secrecy of data, objects, or resources. o Two-factor authentication to access sensitive data  Integrity- Concept of protecting reliability and correctness of data. o ATM and bank software ensure integrity by maintaining up to date monetary records  Availability- Authorized subjects are granted timely and uninterrupt...
