2 1. The purpose of this document In today s globalized and competitive 24/7 world, getting the maximum out of your production facilities has a direct impact on the bottom line. A key feature is to keep your machines running continuously and with optimal performance and quality. As your machine builder, we offer more than just machines and technologies we also provide the service to maximize uptime and product quality. Our Remote Service can improve uptime and convenience without changing network security procedures or machine operations. For remote service and support, we use Secomea s state-of-art Remote Device Management (RDM) solution, allowing us to provide previously unattainable levels of uptime through high-speed and secure communication for service and maintenance. Security is priority number one in this solution. Both security for you as our customer and security for us as your machine builder and service provider. Our Remote Service is your gateway to a global network of service specialists from us. Figure 1: Your insurance for secure and seamless remote support when needed is based on a SiteManager at each production plant. This document describes the set-up using the SiteManager 3000 series, but is not limited to this series only. 2. What is a SiteManager? A SiteManager is the part of the Secomea Remote Device Management Solution that is placed locally at your production facility for monitoring the equipment and for providing the access path to the central surveillance server (GateManager). The SiteManager is not a VPN router where security depends on configuration and maintenance, but an intelligent communication unit specifically designed to accommodate the requirement for secure remote access for the industrial- and automation industry without risks and complexity. The SiteManager 3000 represent the off-the shelf series of Secomea Site- Manager hardware appliances that are specifically designed for deploying in production facilities where uptime is important.

Typical Installation The SiteManager 3000 appliance is a standard component in our all machines where the typical installation is illustrated in figure 3 below.

First of all, any remote access to / from the SiteManager is controlled by you. This can be enabled / disabled on demand via a local web interface or simply by unplugging the SiteManager. Secondly, the SiteManager is by default closed for any access to any equipment on your production network that you have not specifically allowed it to access. Once configured by you or us in agreement with you, the Site- Manager can establish access to only the specified equipment. The SiteManager can enable remote access a specific machine or all its associated components using the network ports (DEV1-4), either based on specific IP addresses or entire subnets. Additional the Serial port can be used for connecting a device that does not have native network support, and SiteManager intelligently bridges IP to RS232. Extraordinarily the SiteManager can be configured to also allow access only to specific IP addresses on the Uplink subnet (the dotted green in figure 3). The SiteManager makes an encrypted connection using the network port (UPLINK) to the GateManager server located outside the production network. The IP address of the SiteManager itself is in principle irrelevant, since all access is administered intelligently by the GateManager. Once remote access to the SiteManager is granted for the GateManager, authorized personal from us can administer it and grant access for relevant Field Engineer/Service Engineer accounts. These accounts are easily ad- Secure & Seamless Remote Device Management Page 4 of 8

The LinkManager software client, used by our Field Engineer/Service Engineer to obtain access to the industrial equipment through the SiteManager, uses the same web banking access principles. The Gatemanager will ensure that the LinkManager only allow access to the SiteManagers and associated equipment that the Engineer s account provides access to. When the connection is established to your plant, the local SiteManager furthermore logs activity any time the Engineer actually uses a connection. The log can then be viewed in the local web interface of the SiteManager, or centrally on the Gatemanger. 5. How is Security ensured in the Office Network? It is important not to compromise corporate firewall security policy. When using the office network for accessing the internet, the connection from the SiteManager to the GateManager has to go through your Corporate Firewall. This is done using one of the ports 80/443/11444, with or without a proxy firewall, depending on what your IT department requires. The port only needs to be opened for outbound traffic. In most cases no changes are needed in your corporate firewall, because there is already a suitably configured port available. I.e. if the network allows you to browse the Internet, the SiteManager will be able to establish its secure connection also. It is also important not to be or become, even unintentionally, a threat on the office network. The SiteManager has a built-in stateful-inspection firewall configured to block all communication except authorized and encrypted data sent between the SiteManager and the GateManager. Furthermore the SiteManager is based on a hardened operating system, which prevents hostile persons or programs to from exploiting the connection. This neutralizes both internal and external threats. The actual connection between the SiteManager and the GateManager is encrypted using the strong AES standard. Each SiteManager is identified by a factory x.509 digital certificate. The solution fulfils all the security standards stipulated by the National Institute of Standards and Technology ( for encryption and key negotiation. It has complete endto-end security, ensuring that no one - and nothing - can access equipment without permission. 6. How is Security ensured by us? End-to-end security is provided not only between the SiteManager in the production network and our head-quarter where the GateManager is installed, but all the way from our Field Engineers/Service Engineers using the LinkManager client software. Only authorized personal can access the GateManager, and each person is identified by both a factory x.509 digital certificate and password (two-factor security) similar to the authentication method used for web-banking. With the advanced role management module in the GateManager, any remote access by authorized personal is managed centrally. This includes controlling which SiteManagers / production networks a person have access to, A person no longer working within our company will have his certificate and account shut down instantly. Any activity is logged not only in your local SiteManager, but also centrally in the GateManager and on the PC of the LinkManager user. Secure & Seamless Remote Device Management Page 5 of 8

6 7. Why choose Remote Service? As your trusted supplier, you buy more from us than our machines and technologies you buy uptime and quality. Complex equipment and process lines within industrial automation are expensive. Optimal utilization is necessary to ensure profitability. Downtime scheduled or not is both costly and critical.
