Industrial Ethernet Architecture and Information Security Threats

Bill Lydon for Automation.com

As Industrial Ethernet protocols have proliferated in industrial production, IP devices have become vulnerable to cyber threats. As one security expert noted: “Any device with an IP address can be hacked.” Oddly enough, at the same time, when the importance of protecting against cyber threats is strongly emphasized, the organizations involved in the development and promotion of Industrial Ethernet do not yet have solid plans to migrate to new standards, although they offer higher security.

Integration of production and business

The value of using Ethernet technology is obvious. Ethernet allows companies to implement new approaches to production, including “custom-made” and mass customization - which require “flexible” industrial enterprises and interactive communication with all participants in the process, including customers, purchasing departments, equipment, conveyors, workers. Ethernet is becoming a unifying communications technology to increase production flexibility and better meet customer requirements. However, there is a serious challenge - the integration of business and production automation systems. It is described by international standards such as ISA-95 and others, which serve as the basis for the development of standard interfaces between automation systems, ERP, MES, etc.). Historically, multilevel configurations have been driven by the cost of computing resources and network bandwidth. In the new model, controllers send information to all levels directly, from levels 0 and 1 to levels 4 and 5, using the appropriate protocols, primarily web services information security job description.

Ethernet communications made it possible and desirable to create streamlined 2- or 3-level automation systems that can increase productivity and reduce costs (see the material “Simplifying the hierarchy of automation systems” ).

Industrial Ethernet technology lags behind

Ethernet technology is moving towards IPv6 for new features and enhanced security. Meanwhile, Industrial Ethernet network standards have not yet been brought into compliance with IPv6 requirements. Most consider IPv6 only as a way to increase the number of IP addresses available, however, the benefits are, in fact, much greater.

Routing Simplification - IPv6 reduces the size of routing tables and makes them more efficient and hierarchical. In addition, in IPv6 networks, fragmentation is not carried out by the router, but by the sender, which determines the Maximum Transmission Unit (MTU).
More efficient packet processing - Simplified packet headers in IPv6 allow you to process them more efficiently. Compared to IPv4, IPv6 does not use IP-level checksums and does not need to be constantly checked. This is made possible because most link layer technologies already use checksums and error control functions. In addition, most transport layers also use checksums to detect errors.
Managed data streams - IPv6 supports a modern multicast method that saves bandwidth. There is a new field in the IPv6 header, called a stream label, that allows packets that belong to the same stream to be identified.
Simplified network configuration - IPv6 has built-in address auto-configuration. The router sends the subnet prefix in its “router advertisement” message, and the host uses a unique interface identifier. By connecting them together, the host receives an IPv6 address.
Support for new services - refusal from network address translation (from English: Network Address Translation or NAT), allows you to return to end-to-end connections at the IP level. Peer-to-peer networks are becoming easier to build and maintain, and services such as VoIP or Quality of Service (QoS) are becoming more reliable.
Security - IPv6 provides a set of IPSec protocols to ensure confidentiality, authentication, and data integrity. Due to their ability to contain malicious software, ICMP packets in IPv4 are often blocked by corporate firewalls, but ICMPv6 - an implementation of the Internet Control Message Protocol for IPv6 - may be skipped because IPSec can be applied to ICMPv6 packets.
The IT industry fully and fully supports this movement, as comments from industry leaders show. John Chambers, president and CEO of Cisco Systems, said: “If we do not overcome the IPv4 problem, we will slow the growth of the Internet and, accordingly, the pace of industry development. IPv6 matters to us all - to almost all people around the world. It is critical to our ability to connect people and devices together. ”

Cisco has an interesting interactive page that provides information on the distribution of IPv6 in different countries. Statistics are updated daily, both globally and at the country level.

Internet Protocol Security (IPsec)

A fundamental improvement to IPv6 is Internet Protocol Security (IPsec), a set of protocols for securing IP communications, by authenticating and encrypting each packet in an IP communication session. IPsec also includes protocols for mutual authentication of agents at the beginning of a session and negotiation of the cryptographic keys to be used during the session. IPsec is an end-to-end Internet-based security scheme in the Internet Protocol Suite. It can be used to protect data flows between a pair of hosts (host-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). Other common Internet security systems, such as Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Secure Shell (SSH), operate in the upper layers of the TCP / IP model. In this way, IPsec protects any application traffic on the IP network. Applications do not need to be specifically adapted to use IPsec. In contrast, the use of TLS / SSL and other methods with IPv4 requires appropriate adaptation of applications to protect protocols. This greatly increases the user's dependence on the vendor.

But what about industry?

I interviewed the major groups involved in the development of Industrial Ethernet protocols regarding plans for IPv6 and at this stage no one said anything specific. The main strategies for today include the continued use of Industrial Ethernet protocols based on IPv4, using private spaces of IP addresses VPN, as well as network address translation (NAT). Using NAT, however, is contrary to the policies of many IT organizations. In general, standardization organizations and vendors in the field of industrial automation do not yet have a solution to the IPv6 problem.

Thoughts & Observations

The fusion of business and manufacturing processes is the main driving force behind data integration in enterprise and industrial Ethernet. It is not so easy to achieve the implementation of this concept, which has already received various names, such as “IT for automation”, “Industry 4.0”, “IP advantages in industry”, “Integrated industry”. First you need to solve some technical problems. In my opinion, the lack of clear plans for IPv6 in the industrial automation industry is a worrying phenomenon, as the IT industry is already actively taking advantage of IPv6, especially in the area of ​​information security.  

Cisco TrustSec - New Network Security Architecture

Cisco has introduced a new network security architecture to the market - Cisco Trusted Security (TrustSec), which integrates the identification and accounting functions of employees across the corporate network.

According to Cisco, the new TrustSec platform creates a “trusted enterprise network” that integrates the switches, routers and controllers of this vendor's unified wireless network, which perform user authentication, role distribution, support for access rules and protect the confidentiality of network traffic network architecture job description.

“The Cisco TrustSec architecture creates a scalable topology that is independent of network access technology and supports data integrity and privacy at the 2nd network layer. As a result, we get technology that solves the problems of “blurring” the boundaries of corporate networks and tightening regulatory requirements, ”said Uwe Fischer, information security manager at E.ON.

Cisco has announced its readiness to work with industry leaders to ensure the compatibility of its new architecture with their network devices. Thus, Cisco and Intel agreed to jointly support the IEEE 802.1AE encryption standard, which helps the network intelligently prioritize data based on the goals and objectives of the business without compromising the integrity of encrypted data. This will help ensure full compatibility between Cisco TrustSec switches and Intel Ethernet controllers that support the IEEE 802.1AE standard.

Cisco also announced that the test equipment of Ixia, a provider of IP performance testing solutions, will support IEEE 802.1AE line cards with encryption capabilities, enabling customers to test Cisco TrustSec switches.

Seller consistence isn't just about taking a gander at the immediate communication your organization has with a merchant. It's likewise about normally dissecting how much hazard the seller has alleviated through its own inside endeavors.

On the off chance that your examination finds that a specific merchant is a high danger of breaking its consistence with your organization, at that point it's a smart thought to alleviate that hazard by searching for another seller.

4 - Use a seller the executives framework

A merchant the board framework (VMS) is an electronic programming that permits you to make a deliberate methodology towards sellers, putting away every bit of merchant information in one simple to-utilize arrangement.

Dealing with your seller consistence through dispersed archives, various groups and no brought together methodology can be confounding and complex. A VMS expels this disarray by permitting your organization to gather, store, oversee and examine information in one effectively available area - that is bound together over your whole association.
