Pen Testing OT Firewalls Without Disrupting Operations
How to pen test OT firewalls safely—passive discovery, controlled active testing, and IEC 62443 alignment without disrupting industrial operations.
Do you know what is connected to your network and where all the devices are? Most businesses don’t…or they think they do until they go through Red Trident’s Asset & Network Discovery.
Each device in your environment has the potential to become an attack vector, therefore it’s important to know what you have in order to keep it protected. In many cases, clients get surprised by our findings and often find numerous additional devices than they expected.
Having an asset inventory is one of the first steps to a successful cybersecurity strategy.
OT CYBERSECURITY & THE IMPORTANCE OF KNOWING WHAT YOU HAVE
Over a decade ago OT cybersecurity wasn’t a huge problem since OT was kept separate from IT. Over the years, as more and more devices become interconnected and linked to the cloud, OT cybersecurity is becoming a large risk that deserves more attention. For further reading, check out our article, The Need for OT Cybersecurity.
Digital transformation of OT environments has led to a rapid growth in the number of devices such as ICS, SCADA, and DCS communicating with the cloud. There’s also a huge increase in more general IP-connected devices such as CCTV cameras, thermostats, badge readers, multi-function printers, and IP phones that have the potential to be connected to the internet, thus providing another vector that needs to be secured.
Benefits of Asset & Network Discovery
All too often we see customers deploying technology to protect assets before they really know what they have or how they use the network. Without a firm understanding of these matters, the technology is often deployed and not configured optimally.
- Comprehensive understanding of your environment
- Typically find devices you didn’t realize you still had (and data flows that should have been removed years ago)
- Clearly identify areas of concern so vulnerabilities can be addressed
- Having this foundation, allows you to produce more focused and accurate risk assessments as well as an accurate and detailed remediation plan, saving you time and money down the road
When it comes to OT cybersecurity, what we cannot measure, we cannot control. And what we cannot see, we cannot secure. That’s why OT Asset & Network Discovery is the first step in the cybersecurity journey.
The OT Asset & Network Inventory Comes in Handy with the Following:
- Vulnerability Assessments
- Penetration Tests
- Incident Response
- Understanding When to Upgrade & When to Make Something Obsolete
Our Asset Discovery Approach
Red Trident employs a multi phased approach when it comes to asset and network discovery. This allows us to be efficient and effective, saving the client time and money.al information (remotely)
What You Receive with the Asset & Network Discovery
Our deliverables will be developed in Microsoft Visio and provided in .vsd and pdf format. This information is vital to have in order to work towards a more secure environment.
