        "text": "For any installation of software related ABB products we strongly recommend the following (non-exhaustive) list of cyber security practices:\n\n\u2013 Isolate special purpose networks (e.g. for automation systems) and remote devices behind firewalls\nand separate them from any general-purpose network (e.g. office or home networks).\n\n\u2013 Install physical controls so no unauthorized personnel can access your devices, components, peripheral equipment, and networks.\n\n\u2013 Never connect programming software or computers containing programing software to any network other than the network for the devices that it is intended for.\n\n\u2013 Scan all data imported into your environment before use to detect potential malware infections.\n\n\u2013 Minimize network exposure for all applications and endpoints to ensure that they are not accessible\nfrom the Internet unless they are designed for such exposure and the intended use requires such.\n\n\u2013 Ensure all nodes are always up to date in terms of installed software, operating system, and firmware\npatches as well as anti-virus and firewall.\n\n\u2013 When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.\n\nMore information on recommended practices can be found in the following documents:\n- Defense in Depth for B\u0026R products : https://www.br-automation.com/fileadmin/Cyber_Security_-_Defense_in_Depth_for_BR_Products-bdd37e82.pdf",

        "text": "B\u0026R has a rigorous internal cyber security continuous improvement process which involves regular testing with industry leading tools and periodic assessments to identify potential product issues. Occasionally an issue is determined to be a design or coding flaw with implications that may impact product cyber security.\n\nWhen a potential product vulnerability is identified or reported, B\u0026R immediately initiates our vulnerability handling process. This entails validating if the issue is in fact a product issue, identifying root causes, determining what related products may be impacted, developing a remediation, and notifying end users and governmental organizations.\n\nThe resulting Cyber Security Advisory intends to notify customers of the vulnerability and provide details on which products are impacted, how to mitigate the vulnerability or explain workarounds that minimize the potential risk as much as possible. The release of a Cyber Security Advisory should not be misconstrued as an affirmation or indication of an active threat or ongoing campaign targeting the products mentioned here. If B\u0026R is aware of any specific threats, it will be clearly mentioned in the communication.\n\nThe publication of this Cyber Security Advisory is an example of B\u0026R\u2019s commitment to the user community in support of this critical topic. Responsible disclosure is an important element in the chain of trust we work to maintain with our many customers. The release of an Advisory provides timely information which is essential to help ensure our customers are fully informed.",
