Security Best Practices

Introduction¶

This guide provides security best practices for deploying and using GuacamoleID. Following these recommendations helps ensure maximum protection for your devices and sensitive data.

Authentication Security¶

Face Profile Best Practices¶

Creating Strong Profiles¶

1. Good Lighting: Register profiles in well-lit conditions
2. Multiple Angles: Look slightly left, right, up, down during registration
3. Consistent Expression: Use a neutral expression
4. Remove Obstructions: Take off sunglasses, move hair from face

Profile Management¶

1. Multiple Profiles: Create profiles for different lighting conditions
2. Regular Updates: Re-register if appearance changes significantly
3. IR When Available: IR profiles are more secure and reliable
4. Limit Profile Count: Only create necessary profiles

Profile Security¶

1. Don't Share Profiles: Each user should have their own profiles
2. Protect Registration: Register in private, secure locations
3. Review Periodically: Audit profile list for unauthorized additions
4. Secure Backup: If using cloud sync, ensure account security

Anti-Spoofing Configuration¶

Recommended Settings by Environment¶

Environment	Minimum Level	Recommended Level
Home/Personal	Passive	Passive
Office	Passive	Active
High Security	Active	Depth Vision
Financial/Healthcare	Depth Vision	Depth Vision

Anti-Spoofing Guidelines¶

1. Never Disable: Always have at least Passive enabled
2. Use Depth When Available: IR cameras provide best protection
3. Test Periodically: Verify anti-spoofing is working
4. Monitor Logs: Watch for spoofing attempts

Block Screen Security¶

Configuration Recommendations¶

Blocking Speed¶

Risk Level	Recommended Speed
Low Risk	Medium
Standard	Fast
High Risk	Very Fast

Block Screen Options¶

1. Key Press to Windows Lock: Always enabled
2. Camera Preview: Consider disabling in high-security environments
3. Registration Button: Disable in high-security deployments
4. Custom Background: Avoid showing sensitive information

Physical Security Integration¶

1. Screen Position: Face away from windows and common areas
2. Privacy Filters: Use physical privacy screen filters
3. Camera Coverage: Ensure camera sees anyone approaching
4. Clean Desk Policy: Lock screen when leaving

Device Security¶

Device Configuration¶

1. Full Disk Encryption: Enable BitLocker or equivalent
2. BIOS Password: Prevent unauthorized boot changes
3. Secure Boot: Enable secure boot in BIOS
4. Firmware Updates: Keep BIOS/UEFI current

Software Security¶

1. Windows Updates: Enable automatic updates
2. Antivirus: Use enterprise-grade protection
3. Firewall: Enable Windows Firewall or better
4. Application Updates: Keep GuacamoleID updated

Network Security¶

1. VPN: Use VPN on untrusted networks
2. WiFi Security: Only connect to secure networks
3. Network Monitoring: Enable network protection features
4. Remote Access: Secure any remote access methods

Account Security¶

Web Portal Security¶

1. Strong Password: Use complex, unique password
2. Two-Factor Authentication: Enable 2FA if available
3. Session Management: Log out when finished
4. Secure Access: Only access from trusted devices

Password Guidelines¶

Requirement	Minimum	Recommended
Length	8 characters	12+ characters
Complexity	Mixed case + numbers	Mixed case + numbers + symbols
Uniqueness	Unique to GuacamoleID	Unique + password manager
Change Frequency	Annually	Every 6 months

Account Recovery¶

1. Recovery Email: Keep recovery email secure and current
2. Security Questions: Use strong, non-guessable answers
3. Backup Codes: Store recovery codes securely
4. Contact Info: Keep phone/email updated

Organizational Security¶

Deployment Security¶

1. Secure Distribution: Use signed installers
2. Configuration Management: Deploy with secure defaults
3. License Security: Protect license keys
4. Enrollment Process: Secure device enrollment

Policy Recommendations¶

Mandatory Policies¶

Policy	Recommended Setting
Anti-Spoofing	At least Passive
Block Screen	Enabled
Auto-Lock	5 minutes maximum
Password Fallback	Enabled

Role-Based Access¶

1. Least Privilege: Grant minimum necessary access
2. Regular Review: Audit permissions quarterly
3. Separation of Duties: Distribute admin responsibilities
4. Access Logging: Enable comprehensive logging

User Training¶

Essential training topics:

1. How face recognition works
2. Importance of anti-spoofing
3. Recognizing security threats
4. Reporting security incidents
5. Privacy and compliance

Data Protection¶

Biometric Data Security¶

1. Encryption: Biometric data is encrypted at rest
2. Local Processing: Recognition happens on-device
3. Minimal Storage: Only necessary data retained
4. Secure Transmission: Encrypted cloud sync

Privacy Considerations¶

1. Inform Users: Explain what data is collected
2. Consent: Obtain proper consent for biometrics
3. Data Retention: Follow retention policies
4. Data Deletion: Honor deletion requests

Compliance¶

Regulatory Frameworks¶

GuacamoleID can help with compliance for:

• HIPAA: Healthcare data protection
• PCI-DSS: Payment card security
• SOC 2: Security controls
• GDPR: Data protection (EU)
• CCPA: Consumer privacy (California)
• BIPA: Biometric information (Illinois)

Documentation Requirements¶

Maintain documentation of:

1. Security policies and configurations
2. User consent records
3. Access logs and audit trails
4. Incident response procedures
5. Training completion records

Incident Response¶

Preparing for Incidents¶

1. Define Procedures: Document response steps
2. Assign Roles: Identify response team
3. Communication Plan: Know who to notify
4. Testing: Practice incident response

Responding to Security Events¶

Unauthorized Access Attempt¶

1. Review authentication logs
2. Identify the source/method
3. Strengthen affected controls
4. Document the incident
5. Report per policy

Spoofing Attack Detected¶

1. Increase anti-spoofing level
2. Review affected profiles
3. Check for successful bypasses
4. Investigate attack source
5. Update security measures

Lost or Stolen Device¶

1. Remote lock/wipe if possible
2. Disable device in portal
