This is Apple iPhone 4s, a smartphone running iOS (capped at iOS 9.3.6), equipped with Apple A5 system-on-chip and PowerVR SGX543MP2 GPU. It features hardware-accelerated iOS Data Protection encryption and Wi-Fi 802.11 b/g/n (2.4 GHz) connectivity, with all firmware signed by Apple, though the device has reached end-of-life and no longer receives security patches. It provides encrypted network communications and full-disk storage encryption via iOS Data Protection, with the encryption ciphers now considered obsolete. User authentication is secured through device passcode, with brute-force lockout protection, access-event logging and setup-time passcode creation. Public hardware tampering methods are limited, known vulnerabilities are rare, and remaining issues are no longer patched by the vendor due to end-of-life status.
For new submissions, pages will appear blank until approval.
