SECURITY YOU CAN
MEASURE ON DEVICE.
Every protection documented on this page is a real platform mechanism read directly from the phone by the built-in Security Center 2.0 app. Nothing here is an unverified label or marketing claim.
Zero open TCP/UDP ports listening on the phone interface.
Zero world-writable files, zero root binaries, zero debuggable packages.
Kernel hardening options merged into MSM8996pro tree in 1.5.0.
The CYRONIX private release key is the only key accepted by OTA & recovery.
Defense In Depth
Security Layer Breakdown
From silicon hardware boundaries to user permissions, every level implements dedicated mitigations.
| Layer | Threat Vector | Protection Mechanism | Implementation Status |
|---|---|---|---|
| HARDWARE | Cold-boot attack, offline memory extraction | Qualcomm hardware cryptographic acceleration, TrustZone TEE, inline eMMC/UFS crypto | IMPLEMENTED |
| BOOT | Modified kernel, physical flash tampering | Recovery signature checks via otacerts.zip. Note: AVB is not supported by 2016 OP3T bootloader. | PARTIAL (Legacy Bootloader) |
| KERNEL | Local privilege escalation, memory disclosure | Yama LSM, software PAN (ARM64_SW_TTBR0_PAN), PANIC_ON_OOPS, removed KALLSYMS_ALL & SysRq | IMPLEMENTED (1.5.0) |
| SELINUX | Process breakout, service compromise | Strict Enforcing mode, zero unconfined domains, granular HAL domain definitions | IMPLEMENTED |
| VENDOR / HAL | Proprietary driver vulnerabilities | Sandboxed userspace HAL services communicating across isolated HIDL binder IPC | IMPLEMENTED |
| FRAMEWORK | Unauthorized background capability abuse | Android 11 permission model, package visibility restrictions, device-admin policy controls | IMPLEMENTED |
| SYSTEM | Physical USB extraction (BadUSB) | Kernel USB Restricted Mode (deny_new_usb): locked phone refuses new USB peripherals | IMPLEMENTED (1.5.0 Default) |
| APPLICATION | Malicious APK data harvesting | UID sandboxing, per-app network firewall, Privacy Dashboard tracking | IMPLEMENTED |
| NETWORK | DNS interception, cleartext MITM | Private DNS over TLS (DoT), strict TLS 1.2+ update server with HSTS and CSP | IMPLEMENTED |
| USER | Brute force passcode guessing | Opt-in auto-erase after 10 consecutive failed unlock attempts | IMPLEMENTED (1.5.0 Opt-in) |
On-Device Verification
Security Center 2.0
One unified screen shows the phone's genuine posture with a score that measures only verifiable system facts:
- Real platform and vendor security patch levels.
- SELinux enforcing status and root binary absence.
- USB restricted mode and lock-screen privacy enforcement.
- Update signing certificate verification (warns if AOSP test keys are detected).
- "Export security report" writes a plain-text report directly to Downloads with zero network access.
