OT Security Pentesting
What is automation security?
Security automation is the use of technology that performs tasks with a reduced human assistance in order to integrate security processes, applications, and infrastructure.
What is the ISA IEC 62443 framework?
The ISA/IEC 62443 series of standards, developed by the ISA99 committee and adopted by the International Electrotechnical Commission (IEC), provides a flexible framework to address and mitigate current and future security vulnerabilities in industrial automation and control systems (IACSs).
What are the four categories of ISA 62443 standards and technical reports?
All IEC 62443 standards and technical reports are organized into four general categories called General, Policies and Procedures, System, and Component.
What is Industry 4.0?
Industry 4.0 refers to a new phase in the Industrial Revolution that focuses heavily on interconnectivity, automation, machine learning, and real-time data. Industry 4.0, encompasses IIoT and smart manufacturing, physical production, and operations with smart digital technology, machine learning, and big data to create a more holistic and better-connected ecosystem for companies that focus on manufacturing and supply chain management.
Which organization bridges the gap between 62443 standards and their implementation?
The International Electrotechnical Commission (IEC) has officially designated the IEC/ISA 62443 series of standards as “horizontal,” meaning that they are proven to be applicable to a wide range of different industries.
Where should you begin your OT cyber security journey?
Almost all industrial businesses are engaged in some form of cyber security. However, the issue of where to prioritize first to increase the security of OT systems comes up frequently. Options often include endpoint protection, network anomaly detection, asset visibility and inventory for improved vulnerability management, and network protection such as segmentation and separation.
Why do you need an OT security program?
Although OT professionals or manufacturers frequently claim otherwise, the truth is that these systems are actually unique. They react slowly to both change and conventional IT security scanning. They have extensive integration. Due to their vast lifecycles, they do run a lot of legacy operating systems. They contain a lot of embedded systems, which are difficult to administer or scan in the same manner as a Windows computer or cloud server. Additionally, responding to a false security alarm has a terrible operational risk. With the proper OT security toolbox, they can be handled. Many of the same controls, such as the CIS Top 20 or NIST CSF, can be used to achieve consistency between IT and OT.
How should an OT security program be managed?
Some important points to remember while managing an OT security program-
- Set a goal that enables tracking and measurement. The CIS top 20 has shown to be quite effective, but there are different targets or models to consider. But making a choice is crucial.
- Obtain alignment between IT and OT and take advantage of each's advantages.
- Gain traction quickly by being aware of the main hazards and addressing the main vulnerabilities and risks.
- By including security into balanced scorecards, you can ensure that results have an influence on performance and create responsibility.
What are the things to keep in mind while choosing an OT security solution?
Things to look for while selecting an OT security solution are-
- If the solution provides asset discovery to enable operational continuity and system integrity.
- If it detects and alerts on known common vulnerabilities and exposures
- The solution should provide IT support in addition to OT
- Solution must support secure IT/OT alignment
- The solution should be able to live in an OT environment from a hardware or operating environment perspective.
What are the main considerations of operations security?
The 5 Steps of Operational Security-
- Identify Sensitive Data.
- Identify Possible Threats.
- Analyze the Vulnerabilities.
- What is the Threat Level?
- Devise a Plan to Mitigate the Threats.
What are examples of industrial automation?
Some of the examples of automated industrial processes are:
- Packaging and material handling.
- Quality control and inspection.
- Metal fabrication; machining, welding, cutting, cladding etc.
- Food and beverage processing.
- Planning and decision making.
What are the advantages of Industrial Automation?
The main advantages of industrial automation are-
- High reliability
- Increased productivity
- Quality enhancement and
- Reduced labor expenses
