Security Embedded Systems

Embedded, Terminal & POS

In today’s interconnected world, embedded systems—ranging from smart home devices to industrial control systems and medical devices—are ubiquitous. These systems control critical processes and often store sensitive data. This is precisely why security in embedded systems is essential.

In modern IT environments, embedded systems, as well as point-of-sale (POS) and payment terminals, are ubiquitous. These specialized devices control production processes, process payment data, or form part of networked infrastructures—making them an attractive target for attackers. Vulnerabilities in the firmware layer, insecure communication interfaces, or poorly protected system configurations can lead to data loss, tampering, or service disruptions.

Many embedded devices contain specialized software and hardware that must address security-critical challenges—ranging from protocol communication and IoT controls to industrial control modules and mechanical systems.

We offer targeted security services for embedded systems and POS environments to provide long-term protection for these critical components, identify vulnerabilities early on, and systematically minimize risks.

Approaches, Procedures & Implementation

• Firmware Analysis & Vulnerability Identification
  In-depth analysis of firmware, interfaces, and protocols
   
• Reverse Engineering
  Investigation of internal processes and unknown security vulnerabilities
   
• Physical & logical attack vectors
  Identification of attack vectors at the hardware and software levels
   
• Configuration & Architecture Audits
  Assessment of the security, up-to-date status, and reliability of embedded systems

Examination Topics

• BIOS Security (Boot Priorities, Default Configuration & Password Security)
• Assessment using compromised boot media
• Security testing of IDS, antivirus, firewall, and protection mechanisms
• Verification of key, HDD, or data encryption
• Attacks via the network and interfaces (Production systems and test environments)
• Security assessment of operating system software (client & server)
• Security assessment of connected web applications
• Security assessment of management or service consoles (terminal & console)
• Security assessment of interfaces (GUI, Control Panel & UI)
• Security assessment of the operating system kernel
• System password assessments – efficiency & weaknesses (BIOS, system, network & keys)
• Security assessment and hardening of deposit/withdrawal modules (dispensers)
• Hardware configuration assessment to identify unique or static backdoors 
  (Generic, secret interactions/tricks, or functional combinations)
• Investigation & testing for vulnerabilities in the cash drawer configuration
• Scanning for known vulnerabilities and security threats
• Security testing of fraud correlation systems and static security mechanisms
• Special case scenarios (reproduction & testing of existing security vulnerabilities)
• Identification of logical errors in functions (manual interaction for manipulation)

Our analyses go beyond simple scan results—we assess actual vulnerability and potential impact on your infrastructure through primarily manual interaction. POS and payment systems process sensitive financial data and are often subject to strict regulatory requirements (such as PCI DSS). Attacks on these systems can not only cause financial damage but also jeopardize trust and reputation.
