LG Shield is a security framework developed by LG Electronics to safeguard products and data.
It integrates a comprehensive range of advanced security technologies across the operating system, framework, and applications to defend devices against evolving cyber threats. LG Shield ensures that users of LG Signage and Commercial TVs can operate their devices with confidence and peace of mind.

Five-Tiered Defense System

LG Shield employs a five-tiered defense system, encompassing the services, application, platform, system (kernel) and hardware. Each layer operates independently to provide robust multi-layer protection against various threats.

Protecting
Data and Privacy

Data transmitted between the server and device is protected using secure cryptographic algorithms and decrypted only after being securely delivered to the intended recipient.

Ensuring Data Integrity

With AppProtect and EKP, LG Shield helps maintain the integrity of sensitive data and source code by preventing them from being altered or tampered with. It ensures the stability of both system and application operations.

EKP
(Enhanced Kernel Protection)

EKP protects the kernel, which forms the foundation of the operating system and its architecture. It blocks unauthorized attempts to modify critical kernel resources in real time.

AppProtect

Applications installed on LG devices are protected from threats such as tampering, rooting, jailbreaking, and unauthorized debugging.
The relevant source code is obfuscated to make analysis and modification more difficult.

Secure FOTA
(Firmware Over-The-Air)

LG Shield ensures safe and reliable over-the-air maintenance by verifying the integrity
and authenticity of all firmware and metadata before installation. Only validated firmware
is applied on the device, preventing unauthorized or tampered updates.

Real-Time Monitoring

LG Shield continuously monitors for malicious activities occurring on the device or network. Also, it analyzes security-related status information to support proactive detection and response to increasingly sophisticated threats.

IDPS
(Intrusion Detection and Prevention System)

To prevent unauthorized activities from external sources and block access by malicious software, both the device and network are monitored in real time. If a security anomaly is detected, all relevant information is promptly reported to the main server and can be extracted as event logs and compiled into reports.

STMS
(Security Threat Monitoring and Response Solution)

Detected threats are promptly transmitted to the server and identified. Rapid response and corrective actions are supported through the dashboard and alert systems. Real-time security status is available, and weekly or monthly reports can be generated to support long-term security analysis.

CC EAL2 Certified

LG webOS 8.0–based display devices, certified with LG Shield, meet the rigorous security standards of Common Criteria (CC). The built-in LG App Monitoring Security Solution has achieved Common Criteria (ISO/IEC 15408) EAL2 certification, validating its proven level of security assurance.

Security Management Process

LG has established processes to ensure security throughout the entire product lifecycle. LG continuously monitors global product security regulations, incorporates them into its internal security policies, and standardizes key security activities to support their consistent execution both before and after product release.
