Understanding Network Vulnerabilities in Mid-Sized Manufacturing Companies


Introduction:

In today's digital age, mid-sized manufacturing companies heavily rely on technology to streamline their operations. However, alongside the benefits, these companies also face various vulnerabilities in their network infrastructure. In this blog post, we will explore some of the key vulnerabilities and risks associated with network security in these companies and discuss potential solutions to address them.


Cloud/Web-Based Applications:

Most mid-sized manufacturing companies make use of cloud or web-based applications for essential processes such as order management, email, accounting, payroll, and inventory. These applications are typically well-protected from external threats as they are hosted on secure servers with redundancy measures in place. However, phishing scams and password hacking remain the primary concerns for these applications. While prioritizing accessibility and connection speed is important, companies must not overlook the potential risks posed by cyber attacks.


Central Server for CNC Programming/CAD:

These companies often have a central server where essential CNC programming and CAD information is stored. This server contains generic CAD/.DXF or G-Code files that are accessed by operators at individual machines for material processing. While access to the server is primarily limited to programmers and operators, the lack of proper segmentation and access controls means that anyone with network login credentials and basic computer knowledge can potentially gain unauthorized access to these files. Furthermore, employees using mobile devices and laptops on-site or for installations and deliveries may connect to the network to update order management applications, creating additional risks.


Machine Access to the Network Server:

The most significant vulnerability lies in managing machine access to the network server. In many mid-sized manufacturing companies, machines have access not only to the file server but also to web applications used for managing inventory and workflows. With high employee turnover rates and multiple shifts, managing passwords and access becomes a challenging task. It is crucial to assess the level of password management and network controls in place, as well as determine the organization's tolerance for potential threats within the physical manufacturing environment.


Addressing the Vulnerabilities:

To mitigate these vulnerabilities, mid-sized manufacturing companies should consider implementing the following measures:


1. Enhanced Security Controls: Implementing robust authentication mechanisms, including two-factor authentication, can significantly reduce the risk of unauthorized access to critical applications and systems.


2. Segmentation and Access Controls: Properly segmenting the network, creating dedicated access groups, and implementing granular access controls will limit the exposure of sensitive data and ensure that only authorized individuals have access to specific resources.


3. Regular Password Changes: Enforcing regular password changes and using strong, unique passwords can help safeguard against password-related vulnerabilities.


4. Employee Training: Conducting regular cybersecurity awareness training sessions for all employees, emphasizing the importance of identifying and reporting phishing attempts, will enhance the overall security posture.


5. Continuous Monitoring and Updates: Regular monitoring of network activity, software updates, and patch management are essential to identify and address any potential vulnerabilities promptly.


Conclusion:

Mid-sized manufacturing companies face specific vulnerabilities in their network infrastructure. By understanding these vulnerabilities and adopting appropriate security measures, companies can protect sensitive data, maintain operational efficiency, and minimize the risk of cyber attacks. Proactive security measures, coupled with employee training and a strong security culture, are crucial for ensuring the long-term success and resilience of these companies in an increasingly connected world.

Internal VPN

 To tighten up home network, and to test,  I recently made a Wireguard server behind the Sophos firewall. My Sophos Firewall is built on an old PC and I have Proxmox on a little mini PC.  The ProxMox server is setup for various services like a Unifi Controller, FreePBX, Wazuh, and most recently a Wireguard server. Essentially, a client at work mentioned that they wanted "everyone to be on a VPN" and a friend was complaining about their VPN not working when they went to the office.  Everyone at the shop mocked the idea and said it would not work....   After building this setup with a Wireguard server and setting up some special rules on the firewall to allow VPN access across VLANS, I am convinced this is the best way to segment a network.  First you can VLAN everything separating various resources but then to limit access within those VLANS is easiest with the Internal VPN server.

 Too Much to talk about: Smart TVs are using the speaker as a microphone- they dont actually turn off when you hit the power button (who would have guessed any of that?  hahahha)....   did an Geolocation ban on my network... why are the "bad countries" always hitting my network?   data has been compromised so many times most people don't even care...   Froze my my credit with the 3 agencies a year or so back...  I would suggest you do it too

Physical Security/Automation

 Fun little project. I had some of these RCWL-0516 boards laying around and a Raspberry Pi Pico so I started to wonder if I could make a motion sensor toy that would turn the lights on as i needed in my little workspace in the basement. Super easy cute python project: basically set it up to sense motion, and close a relay that turns on the LED light.    When you walk in the room the RCWL-0516 senses via microwave that there is motion, tells the Pico and the Pico sends a signal to the relay to close.   The relay will remained closed for 10 seconds after the motion is no longer detected. I am not sure how I am going to use this.... maybe a logging of detected motion and alerts?   IDK yet.
