Decision-makers exploring Security Best Practices: Your AI knowledge database can use Data Analytics & Business Intelligence, Cost Calculator: AI Development, Discover solutions sowie Cost Calculator: AI Knowledge Base as structured entry points.
An AI [knowledge database](/services/ki knowledge database) often bundles the most valuable capital of a company: its collected knowledge, processes, customer information and strategic data.
This makes it an attractive target for cyber attacks and requires a multi-layered security approach.
The most common threats
Data leaks: Unauthorised access to sensitive information
Prompt Injection: KI manipulation by malicious inputs
Insider threats: Abuse by authorized users
Model extraction: Try to steal the trained model
Layer 1: Access Control (Identity & Access Management)
Best Practices:
Implement the **principle of the least privileges * *
Use Multi-factor authentication (MFA)
Perform regular access checks
Join Single Sign-On (SSO)
Layer 2: Data encryption
Type of encryption Application Standard
- *In transit * * Data transmission TLS 1.3
*At rest * Data stored AES-256
- In Use* Data during processing Confidential computing
Layer 3: Protection against Prompt Injection
Short: Prompt Injection is a relatively new type of attack in which attackers try to bring the AI to unintentional behavior by manipulated inputs.
Prompt Injection is a relatively new type of attack in which attackers try to bring the AI to unintentional behavior by manipulated inputs.
Measures:
Input validation: Strict filtering of user inputs
Output filtering: Check of AI responses before output
Sandboxing: Isolation of AI components
**Processing penetration tests
Layer 4: Monitoring and Logging
Short: Implement a complete logging of all accesses and actions.
Implement a complete logging of all accesses and actions. Use SIEM (Security Information and Event Management) systems to detect anomalies.
Conclusion: Security as a continuous process
Short: The security of an AI knowledge database is not a unique project, but a continuous process.
The security of an AI knowledge database is not a unique project, but a continuous process.
By implementing a multi-layered security concept, regular audits and staff training, you can significantly minimize the risks and strengthen confidence in your knowledge management system.
