WHAT IS EMBEDDED SECURITY?
Embedded security is the process of protecting the embedded components and software on embedded devices. It involves applying security features and best practices at the hardware, firmware, and application level. Embedded security is essential for IoT devices, as they are often exposed to various network and physical attacks.
OUR EMBEDDED SECURITY SERVICES
We offer a range of embedded security services to help you secure your devices throughout their lifecycle. Some of our services are:
-
Security Assessment: We perform a comprehensive security analysis of your device, its components, its network, and its data. We identify the potential risks and vulnerabilities, and provide recommendations and solutions to mitigate them.
-
Security Design: We help you design a secure embedded system architecture, using industry-recognized standards and best practices. We select and integrate the appropriate security features and technologies, such as encryption, authentication, secure boot, secure update, and more.
-
Security Implementation: We assist you in implementing the security design, using secure coding techniques and tools. We test and verify the security functionality and performance of your device, and ensure its compliance with relevant regulations and certifications.
-
Security Maintenance: We provide ongoing support and maintenance for your embedded security system. We monitor and update the security status of your device, and respond to any security incidents or issues that may arise.
HARDWARE VULNERABILITIES
Hardware vulnerabilities on embedded systems are flaws or weaknesses in the physical components of a system that can be exploited by attackers to compromise the system’s security. Some examples of hardware vulnerabilities are:
-
Fault injection attacks: These are attacks that manipulate the hardware conditions of a system, such as voltage, temperature, or clock frequency, to induce errors or faults in the system’s behavior. These faults can then be used to bypass security checks, extract sensitive data, or execute malicious code.
-
Physical tampering attacks: These are attacks that involve physically accessing or modifying the hardware of a system, such as removing, replacing, or inserting components, wires, or chips. These attacks can allow attackers to gain unauthorized access, alter the system’s functionality, or implant backdoors or malware. Side-channel attacks: These are attacks that exploit the unintentional leakage of information from a system’s hardware, such as power consumption, electromagnetic radiation, acoustic noise, or timing. These attacks can allow attackers to infer secret keys, passwords, or other sensitive data by analyzing the system’s physical characteristics.
To prevent or mitigate these attacks, embedded systems should implement various security measures, such as secure boot, encryption, access controls, code signing, firmware updates, and hardware security features. We can help you implementing these security measure on a variety of embedded systems.
