MES and Cyber security

MES-cybersecurity

Introduction

Cyber security is more than just a buzzword today - it is an inescapable necessity for protection in the modern industrial landscape. For manufacturing companies, digital transformation has proven to be a double-edged sword. On the one hand, it offers immense opportunities to increase efficiency and automation. On the other hand, it has brought with it a multitude of risks and threats that have the potential to paralyze entire operations.

In our article on MES and cyber security, we aim to examine the critical importance of cyber security in Manufacturing Execution Systems (MES ). In particular, we look at the different aspects of traditional on-premises MES architectures and modern cloud-native MES products.

In light of recent incidents and their severe impact on the manufacturing industry, we will shed light on how companies can protect their critical infrastructures.

Comparing these two approaches will not only provide insight into their respective security features and risks, but also practical insights into how companies can strengthen their defense strategies against the ever-evolving cyber threats.


Cyber attacks in the manufacturing industry

In recent years, cyber attacks in the manufacturing sector have increased significantly, with attackers' tactics becoming increasingly sophisticated. From ransomware that shuts down entire production lines to sophisticated phishing attacks that target highly sensitive company data, the threats are real and costly.

Costs of a cyber security incident

The costs of a cyber security incident can vary significantly depending on the severity of the incident and the size of the organization affected. Direct and indirect costs include:

  • Recovery and repair: costs of restoring compromised systems and data.
  • Legal costs: Costs for legal disputes that could result from the incident.
  • Penalties and fines: Potential penalties associated with data breaches.
  • Loss of reputation: Long-term damage to the brand and customer trust.
  • Business interruption: Losses due to business interruptions and delays.

In 2023, the global cost of cybercrime is estimated to reach over 6 trillion US dollars, double the amount since 2015. These alarming figures underline the growing threat that cyber attacks pose to companies of all sizes and industries.

Especially in manufacturing companies, which are increasingly digitizing, the risks and potential damage from such attacks are particularly high. Reports show that almost 40% of industrial companies have been victims of cyber-attacks in recent years, with the average cost of a single security incident estimated at over 5 million US dollars.

These statistics highlight not only the financial losses associated with cyber-attacks, but also the long-term impact on business confidence, customer relationships and market position. In this context, cyber security becomes not only a technical necessity, but a central part of strategic business management, especially when it comes to the implementation and management of Manufacturing Execution Systems (MES).

 


Part I: On-premises MES solutions

1. Definition and general features of on-premises MES

An on-premises manufacturing execution system (M ES) is a software solution that is installed locally on the servers and computers of a manufacturing company. These systems are designed to monitor and control all aspects of production processes - from raw materials and production planning to quality assurance and delivery. On-premises MES give companies full control over their data and processes, but at the cost of maintaining and managing their own IT infrastructure.

2. Responsibilities for operation

  • Installation and maintenance of hardware
    Companies must procure, install and maintain the necessary hardware, which requires a high initial investment and ongoing costs for hardware updates.

  • Updating and managing the software
    Software updates remain the responsibility of the company, including patch management and ensuring that all systems are up to date.

  • Ensuring data integrity and availability
    On-premises solutions require robust backup and disaster recovery strategies to prevent data loss in the event of hardware failure or cyber-attacks.

3. security aspects

  • Physical security measures
    Physical access to the server rooms must be strictly controlled to prevent unauthorized access. This includes security locks, surveillance cameras and access control systems.

  • Network security and access control
    Network security measures such as firewalls, intrusion detection systems (IDS) and regular security audits are crucial to protect the network from external and internal threats. System-level access control must also be strictly regulated to ensure that only authorized personnel have access to sensitive data and control functions.

  • Security risks and common security threats
    On-premises systems are vulnerable to a variety of threats, including malware, ransomware, phishing and more. The lack of external monitoring and the need to manage security measures internally increases the risk.

  • Measures to prevent and respond to security incidents
    It is critical that organizations have a pre-defined incident response plan that is activated immediately when a security incident is detected. This should include regular security training for employees to educate them on the latest cyber threat tactics and how to recognize and report them.

While on-premises MES solutions offer a high level of control and customizability, they require significant investment in physical and network security measures as well as ongoing system maintenance.

Companies need to weigh these costs and efforts against the benefits of having complete control over their systems and develop a comprehensive security strategy to protect against the increasing number and complexity of cyber threats.

 


Part II: Cloud-native MES based on Microsoft Azure

  • Scalability and flexibility of cloud resources
    Companies can easily adapt their MES capacities to changing requirements without having to invest in new hardware.

3. security aspects

  • Overview of the security features provided by Microsoft
    Microsoft Azure offers a variety of security tools and services, such as Azure Security Center, Azure Firewall and Azure Identity and Access Management, which enable comprehensive security monitoring and management.

  • Data encryption, both in transit and at rest
    Azure encrypts all data in transit and at rest, significantly improving data protection.

  • Identity and access management through Azure Active Directory
    Azure AD provides advanced identity management services, including Multi-Factor Authentication and Conditional Access Policies, which ensure that only authorized users have access to the systems.

  • Compliance and certifications relevant to industry standards
    Microsoft Azure complies with a wide range of international and industry-specific compliance standards, providing additional confidence in the security of the platform.

Cloud-native MES solutions based on Microsoft Azure offer an attractive alternative to on-premises systems, especially for companies that want agile and easily scalable solutions without having to carry the burden and cost of their own IT infrastructure.
