ISA 95 & ISA 99 Standard - IoT Digital Twin PLM

ISA 95

An international standard from the International Society of Automation for creating an automated interface between enterprise and control systems is called ANSI/ISA-95, or ISA-95 as it is more frequently known.

It is a specification created for manufacturers worldwide.

• A vendor-independent description of MOM/MES is provided by ISA 95.
• Offers a structure for MOM requirements that is independent of vendors and users.
• In order to fully reap the benefits of MOM, system vertical integration is typically necessary.
• Well-documented advantages of MOM installations are encouraging more
• The majority of suppliers accept the ISA 95 standard and use it to describe the capabilities of their products.

ISA 99

Global cyber security professionals are brought together by the ISA99 standards committee to create consensus standards that are applicable to all business sectors and critical infrastructure. The ISA/IEC 62443 collection of standards and technical reports, which were created and are still being developed by ISA99 in collaboration with IEC TC 65 WG 10, provides a thorough framework to address and minimize current and future security vulnerabilities in industrial automation and control systems (IACS).

The thirteen publications that makeup IEC 62443 are divided into four categories: general, policies and procedures, system, and component.

The last two groups—System and Component—define the technical specifications for networks and system components while the first two provide concepts, use cases, rules, and processes related to ICS security.

Next, we will examine more closely at these two parts of the standard more.

System prerequisites

The three documents in the System group are focused on design decisions, alterations, or other changes necessary to improve the security of an ICS network.

The first paper (IEC 62443-3-1) gives an overview of the benefits and drawbacks of current network security technologies.

The second (IEC 622443-3-2) deals with network design and security risk evaluation.

In order to reduce threat exposure and spread, it is advised that enterprises divide their networks into zones and conduits, group systems with comparable functions, and impose access restrictions.

Authentication, data confidentiality, and system integrity are only a few of the general system security requirements that are covered in the third document (IEC 62443-3-3), which also emphasizes that performance and availability shouldn’t be jeopardized in the process of meeting these standards.

component specifications

There are two documents in the Component group. The first (IEC 62443-4-1) focuses on a procedure for creating ICS products with the intention of lowering the number of security flaws in control system solutions. The technical specifications for safeguarding the various ICS network components are laid out in the second document (IEC 62443-4-2).

We can pinpoint four actions that industrial operators should do to strengthen the security of their ICS network and successfully implement IEC 62443 based on the needs of the System and Components groups:

Data Collection
If you are unsure of what needs to be secured, you cannot adequately secure your network. A crucial first step to enhancing network security is gathering reliable asset information, including information on how they communicate and how your network functions.

Network Security Evaluation
This step entails examining the outcomes of step one and determining the security posture of your network right now. This will enable you to choose the most effective method for implementing the necessary revisions or adjustments.
Adaptive Build
Step three prepares the network for the implementation of the necessary countermeasures by leveraging the criticalities and priorities defined in step two. Included here are the definitions of protocols, zone identification, and network segmentation, and conduit definitions (i.e., communication flows).
Solution Implementation

Deploying the selected countermeasures, which could, for example, be represented by segmentation and monitoring technology, is the last stage in securing your network.

To keep your network and its processes secure, these precautions must be implemented into regular operations.

It’s crucial to follow the four stages above step-by-step to assure the success of IEC 62443.

A successful conclusion cannot be guaranteed without comprehensive and accurate data and evaluations, the implementation of solutions built around clearly defined procedures, and the network may continue to be insufficiently secured from threats.
