Encrypting data is an excellent example of privacy.
2) Integrity: This principle guarantees that the data is accurate, genuine, and free from the perpetrators of unwanted threats or unintentional changes by the user. If modifications are done, precautions must be taken to protect sensitive information from loss or corruption and to recover quickly. It also indicates that the source of information should be genuine.It means informatin is in the right format.
3) Availability: This principle guarantees that information is always accessible and useful to the people who have access to it. It makes sure that system failures or cyberattacks do not interfere with such access. Ensure the data and resources are available for users who need them.
