Conventional antivirus approaches are often difficult or impossible to use with PC-based automation systems.Therefore, new, industry-compatible security solutions are required that protect against malware without updates and false alarms.
Security concepts known from the office area are rarely or never to be found in the production environment.On the one hand, tailor-made solutions must ensure the desired functions for the user and the process, but at the same time secure this process and the user data.A well-configured hardware firewall, which is systematically installed at the communication nodes, is now a must for every local network.However, this does not mean the firewall built into some operating systems, which the user activates in the hope that it will shield the systems from damage so that the functions and processes run smoothly.Rather, they are dedicated systems that remain responsive with their own resources, especially in the event of hacker attacks.They ensure uninterrupted communication and prevent malfunctions or downtime of the machine or system. Hirschmann stas 3
A firewall makes the decision based on its configured set of rules as to whether a data packet is forwarded or not.The set of rules is based, for example, on the MAC addresses of the senders or recipients as well as IP addresses, port numbers or protocols.The firewall devices from the FL mGuard product family from Phoenix Contact can even make defined bandwidths available to individual processes and limit the number of ICMP packets (pings) or ARP requests.However, the spread of malicious software – i.e. viruses, worms and Trojans – cannot be prevented by a firewall.Because the malware is often spread via protocols that are based on the Common Internet File System (CIFS) or Server Message Blocks (SMB).Data communication based on this protocol family cannot be effectively filtered because the transmission is block-by-block according to a complex procedure.Blocking is also not possible, since the protocols are used in almost every system in the Windows environment.Communication connections via protocols and ports that the machines and systems actually use must not be blocked off by firewalls, even if there is a risk of malicious software being smuggled in.
In the age of numerous variants of the Stuxnet worm tailored to automation systems and similar malicious programs, the dynamic monitoring of the Windows systems used in the productive environment increases the level of security considerably.With the so-called CIFS Integrity Monitoring (CIM), the RS4000 devices of the FL mGuard product family therefore offer industry-standard antivirus protection as an additional license.The CIM, which works like an anti-virus sensor, detects whether a Windows system made up of a controller, operating unit and PC has been attacked by malware without reloading virus patterns or other updates.The security solution can check all the data in a system.However, it usually makes more sense to specify the endangered data types such as DLL, BAT or COM files for the device.The simultaneous use of firewalls and CIM thus allows a high level of protection for systems that were previously considered ineffective to be protected.These include:
