SCADA-Sicherheitsstandards und Best Practices. In order to secure this type of connectivity, VPNs are recommended. Once the door is opened, it is just too easy to cause any number of problems. By: Allan Evora. As reported by news.com.au and other sources, a disgruntled former employee of the contracting firm that installed a computer system for the Maroochy Shire Council, near Brisbane, later hacked into the system. Your alarm system design should define alarms points as sparingly as possible and it should use alarm management as a further measure to reduce the quantity of alarms generated from any process or zone. Since then, the technical standards community has favored authentication over encryption primarily because it is much less resource-intensive and can more reasonably be retro-fitted in existing systems. To detect tampering with process equipment, you can use sanity limits or sanity condition tables to validate commands or process conditions. It is almost impossible to manipulate these « old » protocols and upgrading them may requied  to invest in new components. It is also essential to provide a structure for implementing a cyber security program. Today, information that is widely available – and products and technologies that are now on the market – allow SCADA system operators to install and maintain very secure systems. With cyber-attacks fast becoming the … The backup batteries should be secured inside a locked cabinet with ventilation. 9 SCADA Alarm Management Best Practices That Will Improve Your ROI There's no room in business for the unknown when revenue is on the line. In sectors ranging from manufacturing and utilities to transportation and healthcare, automation makes work easier and more efficient. Protect a SCADA network from the internet threats. GOOD PRACTICE GUIDE PROCESS CONTROL AND SCADA SECURITY GUIDE 7. Design new OT / SCADA systems integrating security from the beginning as opposed to after it has been deployed. If the user forgets to sign off, the RTU should automatically do this after a set time. How to successfully deploy a SIEM solution? In any event, encryption standardization efforts continue and encryption is finding its way into new installations. In the episode in Australia, the attacker targeted the remote stations by using a radio to access serial ports and was able to operate pumps. For the water and wastewater industries, best practices are provided by the "Roadmap to Secure Control Systems in the Water Sector," which was released by the Water Sector Coordinating Council Cyber Security Working Group in 2008. Up to one million liters of raw sewage flowed into the grounds of the Hyatt Regency Resort at Coolum and nearby Pacific Paradise, where it ended up in a storm water drain.” The court statement went on to describe a great deal of environmental damage those attacks caused. SCADA systems are not prevented from the internet threats. They can control large-scale processes that can include multiple sites, and work over large distances as well as small distance. In 2014 ENISA established the ENISA ICS Security Stakeholder Group and in 2015 took over the coordination of EuroSCSIE - European SCADA and Control Systems … SCADA devices do not differ from IT devices in that they also require redundancy, security, reduced costs, and uptime. The DNP (Distributed Network Protocol) Users Group Steering Committee recently ratified a security extension that mandates the authentication of master devices through the use of one-way cryptographic hash functions employing a shared key in order to access critical DNP functions. The RTU should not only report alarms over the SCADA network on a priority basis, it should also keep a date-and-time-stamped record of all alarms and events locally in memory. Entitled Terminology, Concepts and Models,” Part 1 (ANSI/ISA-99.00.01-2007) is part of the overall standard entitled, “Security for Industrial Automation and Control Systems.” This standard lays a solid groundwork for upcoming standards on establishing and operating a security program and technical security requirements, but it is definitely a work-in-process. Deploy and maintain security for your OT / SCADA devices (spoiler alert: number one is OT/IT segmentation). InduSoft Web Studio is an easy-to-use HMIand SCADA softwareRuns on any current Microsoft Operatingsystem (32 and 64 bits) including … Assess remote sites connected to the SCADA network. In areas in which temperatures are often at the extremes of the operating range, battery lifetime is significantly reduced. In order to secure this type of connectivity, VPNs are recommended. A wireless local link, thus, shares a major risk with a remote port, which is defined as one with a modem, radio or other physical connection to a wide area network. Best practices for SCADA software include database connectivity that simplifies the linking of multiple data sources, both to record information and to use data to develop analytic dashboards. Ideally, both the room and the RTU enclosure are secured. InduSoft Web Studio is an easy-to-use HMIand SCADA softwareRuns on any current Microsoft Operatingsystem (32 and 64 bits) including … ESTABLISH ONGOING GOVERNANCE. September 27, 2017.

By using Industrial Defender to maintain an ongoing inventory of cyber assets, automatic reporting is provided for CIP-005-1 compliance. PLC Training Best Practices: 10.1 SCADA & HMI Training Topics: Learn sections 1-9 (PLCs/PACs) before tackling SCADA. Which is why we at ELEKS have compiled a guide on threats to recognise, and the SCADA cybersecurity best practices to implement. For example, such control zone parameters as main power status, battery voltage, cabinet temperature, and door switch status can be reported via SNMP. Competition in the communications industry has resulted in decreasing pricing for hardware that includes cellular radio, licensed radio, spread spectrum radio and wireless Ethernet. Key to this attack is the fact that it was targeted to the remote sites; hence, our focus on this particular aspect of a SCADA system. Best practice is to avoid graphics that replicate analog meters (or at least have visible digital display of analog value above analog meter), using bar or other graph results in better operator interpretation. This page provides abstracts for existing recommended practices and links to the source documents. ESTABLISH ONGOING GOVERNANCE. Are your PLCs obsolete? Is your SCADA system running on a non-supported OS? Nous envoyons quelques emails par an et ne partageons notre liste avec personne. Scada Security Best Practices 1. At the RTU, the standby network uses a separate communication port that is not affected by problems on the primary network port. Subscribe to get unmatched coverage of the oil and gas industry’s entire landscape. •Design new OT / SCADA systems integrating security from the beginning as opposed to after it has been deployed. We help IT and security professionals advance their careers with a full regimen of certification and skills training. SCADA Security Best Practices - Correction Duration: 8:19. Further, the value of risk assessment of these systems is something that cannot just be relegated as irrelevant. 2016, Oshawa Acronym ICS: Industrial Control System DCS: Distributed Control System SCADA: Supervisory Control and Data Acquisition PLC: Programmable Logic Controller RTU: Remote Terminal Unit HMI: Human Machine Interface TCP/IP: Transmission Control Protocol/Internet Protocol IDS: Intrusion … If access control is violated and someone manually changes a process equipment setting, the RTU could detect it and report an alarm. Other challenges include the interconnected nature of corporate networks and control networks such as SCADA, and the division of responsibility for enhanced SCADA security between two separate groups: IT personnel and control system personnel.2 The best practice for RTU location is to place it in a physically secure area. Far worse than that, it creates a situation in which an operator can be easily overloaded and overlook an important development. Log an event for each value change the user makes. Since much of a SCADA wide area network is located, both physically and logically, outside of any of the operator’s secure zones, this is a major cause for concern. Many IP-based systems use encryption and, for those users replacing direct-wire local links with wireless, it is also a feature of Bluetooth. Established in US in 1997Pioneer in industry:First HMI/SCADA package for Microsoft Windows CEWeb solution and XML integration in HMI/SCADAPatent for database connectivityCertifications: 3. This boot camp teaches you how to defend against both internal and external attackers to provide holistic security for critical industrial automation systems. SCADA devices do not differ from IT devices in that they also require redundancy, security, reduced costs, and uptime. The latest technologies, technical solutions and strategies in Exploration, Drilling, Production and more. Rextag database of energy infrastructure assets. While SCADA systems have a number of weaknesses, robust preventative measures can be employed to enhance the security of any industrial control network. Network Security. It is recommended to empower individuals so they are held responsible for their performances related to cyber security, including IT managers, system administrators, technicians and users. If power remains available, many devices allow selection of a “safe mode” for the outputs. Some data communication devices, such as radios, offer it as an option. Use color, motion, and sound sparingly. A New Defense Against Network Attack: Everyone: SCADA Security: Hackers spend months patiently mapping network connections and architecture looking for vulnerabilities. What if the user forgets to close the door? SCADA protocols were created before the internet era and are not adapted to the web environment. Supervisory Control And Data Acquisition (SCADA) have equiped our industries for decades, without really worrying about their vulnerability. Finally, best practices for system design call for provisions in case of RTU failure, regardless of security issues. Database of selected U.S. and international exploration wells. Best Practices When Your Emergency Power SCADA Operating System [still] uses Windows XP or Server 2003. Best practices for both non-virtual (local) and virtual designs are to ensure that processing power and storage capacities are optimized. Another important standard is NSI/ISA-99 (Parts 1 and 2). The RTU should continue operating even in case the network is jammed or one or more ports are kept busy. A number of years ago, Bill Rush of the Gas Technology Institute (GTI) proposed SCADA message encryption to address this risk. Authentication ensures that messages arriving at the RTU come from the control center, or other, legitimate asset in the SCADA system. Exxon Mobil will focus on Guyana, where it discovered up to 8 billion barrels of oil, offshore Brazil, and the Permian Basin oil field, the company said. They also perform … But the recent cases such as DuQu (see more) put the light on the security issues of these systems. Can we learn from SCADA security incidents? Over the past few years, people have continued to ask this author whether there have been any attacks or intrusions into SCADA systems. Wireless interfaces are becoming more popular for local links, e.g. Join InduSoft as we invite Vern Williams, the Chief Security Officer of Cyber Defenses to discuss some of the challenges, and solutions to cyber security threats to SCADA systems. In case of a main power failure, the RTU should include adequate battery backup to continue all operations for a time you determine. Maintaining the security of SCADA systems has always been critical, both to protect intellectual property and infrastructure from internal and external threats. In many systems, it is simply too easy to gain access via an RTU local serial port or, even worse, a dial-up radio or other network link that makes the RTU accessible from practically anywhere in the world. In practice, large SCADA systems have grown to become very similar to distributed control systems in function, while using multiple means of interfacing with the plant. In other industries, computer equipment has been disabled through the use of fire extinguishers, other chemical spray, excessive dust or sand, flooding, sprinkler systems, radio interference and surges on wiring. Good Practice Guide Process Control and SCADA Security. September 27, 2017. While this would amount to a denial-of-service attack on the RTU, we have seen many cases in which the SCADA network was simply overloaded. RAM must be backed up by a battery and Flash, which does not require battery back-up, is now being used more often. One problem with an alarm/event log is a “noisy” alarm condition whose recurring messages fill it up. This could be an alarm, but some users simply log it as an event. Information on their routing and termination locations should be secured. Fortunately, different best practices can reduce their vulnerability and improve SCADA networks security. A searchable database of oil and gas debt and equity offerings. Join our mailing list to receive the latest news and updates from our team. Join … Maintaining the security of SCADA systems has always been critical, both to protect intellectual property and infrastructure from internal and external threats. Modern operational technology (OT) networks are constantly evolving due to developments such as the Industrial Internet of Things (IIoT), Industry 4.0, smart grid and more. wireless HART between an RTU and pressure transmitter and Bluetooth between a lap-top PC and the RTU. If the RTU is not in a physically secure area, then you must keep keypads, pushbuttons, and switches secured. You can expect a maximum of a five-year lifetime from lead acid cell batteries but you should check them at least once per year. SCADA systems are not prevented from the internet threats. If you know that all three compressors shouldn’t be on when line pressure is 800 psi or higher, put that in the RTU. Inscrivez-vous pour garder le contact avec nous. That information can be used for intrusion detection. Map All Current Systems Everywhere your system connects to the internet and internal networks should be documented. You must periodically maintain the batteries on a schedule provided by the battery supplier. Could this sort of attack happen to your system? Not only is this very annoying but, worse, meaningful messages drop out and are permanently lost. When your day-to-day operations impact the daily lives of your community, and people are counting on you to have 100% uptime, the last thing you want to see in a meeting is shrugged shoulders. Meet the author Infosec LinkedIn. Best Practices When Your Emergency Power SCADA Operating System [still] uses Windows XP or Server 2003 . A typical SCADA solution will consist of a multitude of controllers such as PLCs and RTUs manufactured by a mix of vendors. Log an event when the user signs off and either log an event or clear/reset the alarm when the user unplugs the hand held device or PC. If you do, just make sure that they are configured to use the new features. Below are a number of measures that can help operators physically secure the RTU installations in their SCADA system. In case the host computer or network fails, the RTU should independently monitor and control the process. Your first reaction might be that this would add too much complexity to the RTU but some languages make the programming almost as easy as making the statement. Most SCADA software will automatically switch over to a standby network if the primary network fails. when seeking to better secure SCADA networks/systems and ICCP. As arguably one of the most important areas to focus on, network security ensures, for example, that a hacker can't gain access to the power plant controller and delete all of the system logic. Cybersecurity predictions :  what you can expect in 2016, How to create a good password (strong but user-friendly). This time depends on how long you feel it could take to restore main power. Utilities need to be well aware of NERC CIP, which requires compliance in your planning, processes and procedures. Best practices to overcome challenges While SCADA systems have a number of weaknesses, robust preventative measures can be employed to enhance the security of any industrial control network. Area41, (originally named as hashdays in 2010) is one of Switzerland’s best known technical information security conferences, and this event typically also has a SCADA learning side to it as well. Certification of Cyber Security skills of ICS/SCADA professionals; Good Practices for an EU ICS Testing Coordination Capability; Window of exposure… a real problem for SCADA systems? Connecting upstream production to the downstream sector and putting midstream in the center of it all. Visibility is key to securing SCADA Networks as without a clear understanding of the system assets, it is impossible to assess risks and apply effective defences. When your day-to-day operations impact the daily lives of your community, and people are counting on you to have 100% uptime, the last thing you want to see in a meeting is shrugged shoulders. Consequently, if the connexion is not secured, worms can enter the system through the breach. ith the threat of cyber attack growing in recent years, oil and gas pipeline operators are well advised to look for way to protect their SCADA systems. The solution is to conduct a physical security survey and inventory access points at each facility that has a connection to the SCADA system. Unfortunately, it is too easy to say that it is mandatory for the RTU to be physically secure and be done with it. Best Practices When Your Emergency Power SCADA Operating System [still] uses Windows XP or Server 2003. A hacker can very easily crack it and penetrate a SCADA environment.
