Cybersecurity Month: Secure Automation Systems in the Digital World

October 4, 2024

October, known globally as “Cybersecurity Month,” aims to raise awareness of cyber threats in the digital world. Automation systems, especially those involving OT (Operational Technology), IoT (Internet of Things), and industrial devices, pose significant data security risks. These risks can threaten the critical processes of businesses. In this article, we will explore the importance of cybersecurity, the vulnerabilities in industrial automation systems, and the necessary precautions to mitigate these risks.

Security Risks Brought by Digitalization

With the rapid development of technology, the increased use of digital systems has led to a rise in cyber threats. In industrial automation systems, serious security and performance issues can arise in the communication between OT, IoT devices, automation devices, and sensors. These systems are particularly vulnerable to external threats when outdated and insecure protocols are used. Data transmitted without encryption can create security breaches, putting data integrity and confidentiality at risk.

Common Cyber Threats

Common threats encountered in industrial systems can directly impact operational efficiency and data security. Here are some of the most prevalent threats:

  • Ransomware: Malicious software that infiltrates industrial devices, encrypting files and demanding a ransom for decryption.
  • Phishing Attacks: Fake email attacks aimed at stealing personal or corporate information.
  • Insider Threats: Employees, either intentionally or unintentionally, creating security vulnerabilities.
  • Industrial Espionage: Targeting R&D processes and engineering solutions to steal critical information.
General Recommendations for Data Security and Protection

Data security in industrial networks is vital for the safe and efficient operation of systems. Using unencrypted protocols risks data integrity and confidentiality. This can pave the way for cyberattacks, leading to operational disruptions and data loss.

Advanced cryptographic algorithms such as AES and RSA can be used to ensure data security. AES provides encryption during data transmission, while RSA offers secure key management. It is also important to use hardware-based cryptographic accelerators to perform encryption operations without performance loss. This enables secure data exchange between industrial devices.

Secure Communication Protocols and Technologies

Among the secure communication protocols used to enhance data security in industrial systems are MQTTS, HTTPS, and OPC UA. These protocols ensure that data is securely and seamlessly transmitted to the target points. Additionally, by implementing a publish/subscribe model, only relevant data is monitored and securely transmitted. These solutions aim to maximize the security and control of data flows.

Cybersecurity and Building Automation

Building automation systems control critical operations like HVAC, lighting, and energy management. As digitalization becomes more widespread, cybersecurity risks in these systems are increasing. The use of secure communication protocols in these systems is critical for both operational efficiency and data security. At Ges Teknik, we prioritize cybersecurity in our building automation solutions and integrate it into our operational technologies.

Security in R&D and Engineering Services

R&D efforts and engineering services are strategically important for the future of companies. Protecting these activities requires the secure management of IoT devices and digital platforms. With secure protocols and encryption methods, IoT devices can be safely integrated into networks. Ges Teknik strengthens cybersecurity strategies in these areas as well, protecting innovative solutions.

In a digitalizing world, cybersecurity has become an inevitable necessity for both industrial automation systems and building automation solutions. Cybersecurity Month is an important opportunity for businesses and industrial institutions to review their security strategies and prepare for future threats. By integrating secure communication protocols and encryption solutions, you can protect your digital systems and create a sustainable business model.
