Success Stories Pohjolan Voima (PVO) IEC 62443 assessment to patch cyber security gaps Challenge Solution Existing system does not meet modern cyber security standards No regular updates of routines

6 Success Stories Pohjolan Voima (PVO) IEC assessment to patch cyber security gaps Challenge Solution Existing system does not meet modern cyber security standards No regular updates of routines in the old systems when new systems have been deployed Avoidance of intentional and unintentional malfunctions caused by security threats Protection against phishing of valuable information and espionage Deploy the assessment to identify security gaps and measures for risk mitigation based on IEC Investigation of the system s technological cyber security properties (e.g. user and access management, operation logs, level of back-up procedures, data encryption) Analysis of cyber security processes and instructions, such as the ability to react to threats Profile Pohjolan Voima was established in 1943 and produces electricity and heat to its shareholders with hydropower and thermal power. Customer benefit Different perspective than in-house assessments through an external expert Compliance with security requirements set for the business Achieving the desired higher maturity level of Industrial Security Page 6

8 Patch & Vulnerability Management Managing vulnerabilities and critical updates in Microsoft products? = X Customer s challenge In 90% of attacks in 2014, old vulnerabilities that already had patches available were leveraged some of which were more than decade old 1 Patches contribute toward stable system operation and/or eliminate known security vulnerabilities. Regular and prompt installation of patches represents a vital element of a comprehensive security concept Patching with an incompatible patch can cause unplanned downtimes Common approach Customer has to release the Microsoft patches manually on a WSUS, based on Siemens SIMATIC PCS 7 compatibility excel sheet or No patching is performed at all or No WSUS server is used, but patches are downloaded directly by the endpoints Other customer specific solutions (e.g. usage of 3rd party software) are possible Weak points of common approach Possibility of system disruption due to missing consideration of compatibility Possibility of security incident due to obsolete patch status Possibility of failures due to manual work Need to manual check for updated excel sheet on Siemens Website Labor intensive process (monthly occurring) Goal Support customers by testing SIMATIC PCS 7 with Microsoft security and critical patches when new patches are released in order to check the compatibility of the PCS 7 software with these patch classifications 2 and providing metadata about approved patches at the customer site 1) Source CNN Money 2) Only "Security Patches" and "Critical Patches" are necessary to ensure that SIMATIC PCS 7 operation is secure and stable Page 8

9 Security Information Siemens provides products and solutions with industrial security functions that support the secure operation of plants, systems, machines and networks. In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement and continuously maintain a holistic, state-of-the-art industrial security concept. Siemens products and solutions only form one element of such a concept. Customer is responsible to prevent unauthorized access to its plants, systems, machines and networks. Systems, machines and components should only be connected to the enterprise network or the internet if and to the extent necessary and with appropriate security measures (e.g. use of firewalls and network segmentation) in place. Additionally, Siemens guidance on appropriate security measures should be taken into account. For more information about industrial security, please visit Siemens products and solutions undergo continuous development to make them more secure. Siemens strongly recommends to apply product updates as soon as available and to always use the latest product versions. Use of product versions that are no longer supported, and failure to apply latest updates may increase customer s exposure to cyber threats.
