Data resiliency consists of three essential functions:
- Data must be immutable, can not be modified or deleted, and must be kept as long as the organization’s policy requires.
- Stored and transmitted data must use strong encryption and access controls to prevent unauthorized access. This protects the data from malicious activity like ransomware and ensures that data retains confidentiality and integrity.
- Data must be available, redundant, and able to tolerate faults and other outages with no single points of failure.
