Security Considerations
Security is a crucial factor when choosing between on-premise and cloud storage. Both options have security measures and potential risks.
On-Premise Security
With on-premise storage, your company is responsible for protecting its data. This includes:
- Physical security: Locking down servers and data centers to prevent unauthorized access
- Access controls: Restricting access to authorized personnel only, using authentication protocols
- Encryption: Encrypting data at rest and in transit to prevent interception
- Backups and recovery: Regularly backing up data and having a disaster recovery plan
Your company has full control over data and can implement custom security measures. However, you’re also responsible for any security breaches or data losses.
Cloud Security
Cloud storage providers have robust security measures to protect customer data, including:
| Cloud Provider Responsibilities | Customer Responsibilities |
|---|---|
| Securing the infrastructure | Securing data and applications |
| Encrypting data at rest and in transit | Implementing access controls |
