Staying compliant with relevant regulations through proper BI reporting data security avoids significant legal exposure.
Core Data Security Best Practices for BI Reporting
Given the threats and regulatory considerations covered, what are some of the core best practices that should be implemented for securing BI reporting software and data?
Access Controls and User Authentication
Managing who has access to data, and what specifically they can access, is critical for BI reporting security. Key measures include:
| Tactic | Description |
|---|---|
| Role-based access controls | Only allow access to data needed for a user’s role. |
| Least privilege model | Users have minimum required permissions. |
| Strong passwords | Require complex passwords that expire periodically. |
| Multi-factor authentication | Add steps like codes and biometrics to logins. |
| Single sign-on | Centralize access management through one system. |
| Session timeouts | Automatically log out inactive users. |
Data Encryption
Encrypting data, both at rest and in transit, ensures that even if it is intercepted by malicious actors, it remains obscured and unusable. Consider:
| Method | Details |
|---|---|
| Database encryption | Encrypt data stored in databases. |
| File encryption | Encrypt data files outside of databases. |
| Network encryption | Encrypt connections and data transfer via SSL/TLS. |
Network Security and Firewalls
As BI reporting platforms interact with various data sources on behalf of users, the network perimeter must be hardened. Tactics involve:
| Tactic | Description |
|---|---|
| Segment BI systems | Isolate BI servers, software, and data from general network. |
| Firewall rules | Restrict connections to trusted IPs and ports. |
| Web application firewalls | Inspect traffic to reporting interfaces. |
| Intrusion detection/prevention | Automatically block malicious network activity. |
Backup and Disaster Recovery
Unplanned outages and data loss could mean BI reporting ceases to be available when it’s needed most. Ensure continuity via:
| Tactic | Description |
