Classification

Device
Criterion	Value	Proof(s)	Comment
Known hardware tampering	Rare	[2]	As a legitimate brand device, widespread hardware-level malicious tampering is uncommon, but risks may exist with unofficial repair channels.
Known vulnerabilities	Rare	[3]	Runs a relatively new Android 13 OS. Fewer model-specific vulnerabilities have been disclosed compared to outdated models.
Prior attacks	Rare	[4]	No widely reported targeted attacks against the Coolpad 50s have been documented to date.
Updatability	Rare	[5]	As an entry-level model, receiving major Android OS upgrades and long-term security patches is likely limited.
Category score	2

System
Criterion	Value	Proof(s)	Comment
Authentication with other systems	Partial	[6]	Supports basic screen lock methods (pattern, PIN, password). Integration with advanced external authentication systems is limited.
Communications	Encrypted with up-to-date encryption	[7]	Supports modern TLS protocols for network communication encryption.
Storage	Encrypted with up-to-date encryption	[8]	Based on Android 13, it should utilize up-to-date File-Based Encryption (FBE) for storage security.

Criterion	Value	Proof(s)	Comment
Account management	Basic	[9]	Provides basic Google account and device screen lock management. Lacks advanced enterprise-grade features.
Authentication	Basic	[10]	Relies on basic knowledge factors (PIN/pattern/password). May lack multi-factor authentication support.
Brute-force protection	Basic	[11]	Includes fundamental protections like time delays after failed attempts. Advanced features may be absent.
Event logging	Partial logging	[12]	The system has basic logging capabilities, but detailed security event logs might not be fully accessible to users.
Passwords	Require change after setup	[13]	May prompt for a password change upon initial setup, but enforced complexity requirements are unlikely.
