Study Notes
Security Goals of Certificates
- Certificates ensure Guaranteed Authentication and Encrypted Communications.
Manual Distribution of Certificates
- Certificates can be shared via email attachments or through secure websites for download on Apple devices (iPhone, iPad, Mac).
Automatic Distribution of Certificates
- Certificates can be automatically distributed using Mobile Device Management (MDM) payloads and profiles, exemplified by systems like Active Directory.
MDM Certificate Management
- MDM solutions can monitor all certificates installed on a device and remove any that were deployed through the MDM system.
Certificate Validation
- The Online Certificate Status Protocol (OCSP) is utilized to check the validity status of certificates, ensuring they haven’t been revoked.
- Devices running iOS, iPadOS, and macOS periodically validate OCSP-enabled certificates.
Handling Untrusted Certificates
- Certificates that cannot be verified as authentic show up as ‘Untrusted’ (unsigned), allowing users to decide whether to install them.
- Even with an unsigned certificate, communications between hosts remain encrypted despite lacking authentication assurance.
Manual Removal of Certificates
- On Mac: Use Keychain Access app, select the certificate, and delete it.
- On iPad/iOS: Navigate to Settings > General > VPN & Device Management, select the profile, view more details, and choose the certificate to remove.
