Information to Avoid Sharing or Search with AI Chatbots

Introduction:

In today's rapidly evolving digital landscape, artificial intelligence chatbots have become integral tools in various business operations. However, their increasing adoption brings significant information security challenges that organizations must carefully address. The interaction between users and AI chatbots creates unique vulnerabilities that could potentially expose sensitive information, making it crucial to understand what information should be protected and how to implement appropriate safeguards.

The primary concern stems from the fact that AI models may retain information from interactions and could potentially expose sensitive data through various attack vectors. Organizations must therefore maintain a delicate balance between leveraging AI capabilities and protecting sensitive information. This requires a thorough understanding of different categories of sensitive data and the implementation of robust security measures to prevent unauthorised access or exposure.

An information security perspective, here are important items that should not be searched or shared with AI chatbots, as this could create security risks:

1. Authentication Credentials and Secrets:

• Passwords & API keys: Even if encrypted or hashed, never share these as AI models could store them
• Private encryption keys: Both symmetric and asymmetric keys used for data encryption
• Database connection strings: These contain server locations, usernames, and passwords
• Login credentials: Including temporary passwords, 2FA backup codes, or recovery phrases
• SSH keys and certificates
• OAuth tokens and session identifiers
• AWS/Cloud platform access keys
• Service account credentials

2. Personally Identifiable Information (PII):

• Government identifiers: SSNs, passport numbers, driver's license numbers
• Financial details: Credit card numbers, bank account info, routing numbers
• Contact information: Email addresses, phone numbers, physical addresses
• Personal attributes: Date of birth, place of birth, mother's maiden name
• Biometric data: Fingerprints, facial recognition data, voice patterns
• Medical identifiers: Health insurance numbers, patient IDs
• Employment information: Employee IDs, payroll details
• Educational records: Student IDs, academic transcripts

3. Confidential Business Information:

• Trade secrets: Manufacturing processes, formulas, designs
• Source code: Proprietary algorithms, internal tools, unreleased features
• Security policies: Incident response plans, security protocols
• Network details: Architecture diagrams, system relationships
• Employee data: Organizational charts, compensation details, performance reviews

• Partner agreements: Contract terms, NDAs, licensing agreements

4. Sensitive Organizational Data:

• Financial data: Revenue figures, profit margins, investment plans
• Customer information: Sales data, behaviour analytics, preferences
• Meeting minutes: Board meetings, executive discussions
• Project details: Timelines, resources, milestones
• Vendor relationships: Pricing agreements, service levels
• Market analysis: Competitive research, industry insights
• Audit reports: Internal findings, compliance assessments
• Performance metrics: KPIs, growth targets, efficiency measures

5. Infrastructure Details:

• Server information: Hostnames, OS versions, patch levels
• Network configuration: Routing tables, firewall rules, VPN settings
• IP addressing: Internal IP schemes, subnet masks, DHCP ranges
• Security tools: AV configurations, IDS/IPS rules, logging settings
• System access: Admin accounts, privilege levels, access controls
• Backup systems: Schedules, storage locations, retention policies
• Development environments: Test servers, staging platforms
• Cloud resources: Instance details, storage configurations

6. Regulated/Compliance Data:

• Healthcare (HIPAA): Patient records Treatment plans Medical history Insurance information Provider notes
• Financial (PCI DSS, SOX): Credit card processing data Financial statements Audit trails Transaction records Investment portfolios
• Educational (FERPA): Student grades Attendance records Disciplinary actions Financial aid information Academic evaluations
• Privacy Laws (GDPR, CCPA): Data processing records Consent management Privacy impact assessments Data transfer agreements

The key security concern with sharing any of this information with AI chatbots is that:

• The data could be incorporated into training sets.
• It might be exposed through prompt injection attacks.
• There's no guarantee of data deletion.
• The information could be used to build detailed profiles of organizations.
• It could enable social engineering or targeted attacks.

Best practices for protecting each category of sensitive information when working with AI systems:

1. Authentication Credentials and Secrets:

• Implement a robust secrets management system (like HashiCorp Vault or AWS Secrets Manager)
• Use environment variables instead of hardcoding credentials
• Rotate credentials regularly and automatically
• Apply the principle of least privilege
• Use separate credentials for development, testing, and production
• Enable multi-factor authentication (MFA) wherever possible
• Monitor and log all access to credential storage systems
• Use password managers for organizational password management
• Implement automated credential scanning in code repositories

2. PII Protection:

• Encrypt PII data both at rest and in transit
• Implement data masking and tokenization
• Maintain detailed data inventory and classification
• Regular PII scanning and discovery across systems
• Clear data retention and deletion policies
• Implement role-based access control (RBAC)
• Regular privacy impact assessments
• Employee training on PII handling
• Geographic data segregation for compliance

3. Confidential Business Information:

• Implement digital rights management (DRM) solutions
• Use watermarking for sensitive documents
• Maintain detailed access logs
• Regular security clearance reviews
• Implement data loss prevention (DLP) tools
• Strict NDA policies and enforcement
• Clear document classification system
• Regular audits of access patterns
• Secure file sharing solutions

4. Sensitive Organizational Data:
