Security Evaluation

1. Device Security

Criterion	Value	Proof	Comment
Known hardware tampering	Rare	—	Requires physical access and disassembly; no external interfaces besides the button.
Known vulnerabilities	Rare	🔗 Proof	Minor information disclosure vulnerabilities exist, but no critical RCEs are widely exploited.
Prior attacks	Rare	🔗 Proof	No major widespread botnet attacks recorded; low-value target for ransomware.
Updatability	Very common	🔗 Proof	Firmware updates are managed automatically via the Kasa Smart App.
Category Score	Score: 2 / 3

2. System Security

Criterion	Value	Proof	Comment
Authentication with other systems	Full	🔗 Proof	Requires a TP-Link cloud account (TP-Link ID) for remote access and integration.
Communications	Encrypted with up-to-date encryption	🔗 Proof	Uses TLS encryption for cloud communication.
Storage	Encrypted with up-to-date encryption	—	Only stores basic scheduling and cloud account data; highly secured by AWS/cloud provider.
Category Score	Score: 1 / 3

3. User Authentication

Criterion	Value	Proof	Comment
Account management	Full	—	Centralized management via the Kasa App and TP-Link ID.

The TP-Link Kasa HS103 is a simple smart plug with a small attack surface. It relies heavily on the Kasa cloud infrastructure and the security of the user's TP-Link ID. While minor vulnerabilities have been recorded, the device lacks complex hardware that would allow for deep exploitation. It uses modern TLS encryption for communications and enforces strong account security, making it a relatively low-risk device in a smart home ecosystem.
