Chapter: Security And Disaster Recovery
Data security involves protecting digital information from unauthorized access, corruption, or theft throughout its lifecycle. Below are common security risks and mitigation strategies organizations must consider to protect sensitive data.
1. Security Risks
a. Hardware Failure
Risk:
The failure of physical components such as hard drives, SSDs, power supplies, or RAID controllers can lead to data loss, corruption, or service downtime. This is particularly critical in environments without redundancy or proactive hardware monitoring.
Technical Details:
- Traditional HDDs have mechanical components (e.g., spinning platters, read/write heads) that wear out over time.
- SSDs can fail due to NAND flash memory wear (measured in write cycles).
- RAID controllers may introduce single points of failure if not configured with redundancy.
- Power surges or overheating can accelerate hardware degradation.
