Improving SCADA System Security. Introduction. Supervisory control and data acquisition SCADA networks contain computers and software that perform critical tasks and provide essential services within critical infrastructure. Theyre considered by cyber strategists to be the backbone of any country. Critical infrastructure, and in particular control systems, require protection from a variety of cyber threats that could compromise their ordinary operation. These systems are used to monitor the key parameters of production processes and to operate their control to ensure the proper provisioning of critical services. Originally, these systems were designed in an environment with the sole intent to monitor processes without considering the security requirements and the needs to protect them from external threats. These systems have a life cycle of decades. Many of those critical components that operate today do so in a context thats completely different from the one they have been designed for. Theyre exposed on Internet with obvious security risks. As a result, almost every SCADA performs well. Theyre reliable and flexible, but often lack security. The impairment of SCADA networks could cause interruption of critical services, process redirection, or manipulation of operational data that could have serious consequences for the population.

What are the best practices to implement to improve the security of SCADAs What actions need to be taken to secure legacy systems This article will provide a few suggestions to improve the security of SCADAs. Current scenario. After recent events, many security firms have started designing solutions to address security problems of SCADA systems. But the major challenge for governments is the inclusion of protection for these critical components in their cyber strategies. Scada Pdf NptelSeveral audits executed by governments on their critical infrastructures have illustrated a dangerous scenario. They demonstrate the lack of security mechanisms for the many systems located all over the world. Scada Pdf In Hindi' title='Scada Pdf In Hindi' />But what is really concerning is the absence of a precise census of SCADA systems for many industrialized countries. Events such as the Stuxnet virus and last years alleged incident of the water facility in Illinois have shown to the world that its possible to conduct terrorist attacks on foreign states remotely. This has increased awareness of cyber threats, and the need to implement proper countermeasures to mitigate risk. With defense mechanisms virtually absent, SCADA system components are often under the government of local authorities who dont deal with adequately trained personnel who operate with limited budgets. This means that these kinds of control devices are installed everywhere without being qualified in the installation phase.

There are many systems deployed with factory settings, pre set standard configurations, and theyre common to entire classes of devices. Even those who maintain that they shouldnt exceed security, thus making it accessible for remote diagnostics without necessary attention. Fortunately, something changed. Precise guidelines identify the best practices to follow in the management of SCADA systems, and operations groups monitor the operation of facilities around the country. The last INTERNET SECURITY THREAT REPORT published by Symantec reports that in 2. SCADA vulnerabilities, a massive decrease over the 1. Since the emergence of the Stuxnet worm in 2. SCADA systems have attracted more attention from security researchers. Scada Pdf' title='Scada Pdf' />In a SCADA system, the programmable logic controllers PLCs are directly connected to infield sensors that provide data to control critical components e. Centrifugal or turbines. Often the default passwords are hard coded into Ethernet cards the systems use. Those cards funnel commands into devices, allowing administrators to remotely log into the machinery. Hard coded passwords are a common weakness built into many industrial control systems, including some S7 series of PLCs from Siemens. Because the systems control the machinery connected to dams, gasoline refineries, and water treatment plants, unauthorized access is considered a national security threat. They could be used to sabotage operation. Doing a search on the Shodan server search engine, you can find what appear to be working links to several vulnerable Schneider models. Its very worrying, and reveals the need for radical change. Fortunately, the emergency has been noticed by most countries. The ENISA European Network Information Security Agency, has produced recommendations for Europe and member states on how to protect Industrial Control Systems. The document describes the current state of Industrial Control System security and proposes seven recommendations for improvement. The recommendations call for the creation of national and pan European ICS security strategies, the development of a Good Practices Guide on the ICS security. They would foster awareness and education, as well as research activities or the establishment of a common test bed and ICS computer emergency response capabilities. The case. Immediately after the Stuxnet virus, governments and intelligence agencies all over the world requested assessment of security for critical infrastructure of their countries. Much of the focus was on evaluating efficiency offered by defensive measures adopted to protect SCADAs and ICSes from cyber attacks. After Stuxnet, debate on the use of software and malicious applications of information warfare have increased. Governments are investing to improve cyber capabilities working on both the defensive and the offensive side. Despite greater awareness of cyber threats, critical infrastructures of countries are still too vulnerable. Many security experts are convinced that an imminent incident caused by a cyber attack is likely soon. Just a few days ago, Eugene Kaspersky, CEO of Kasperky Security, revealed that a staffer at the unnamed nuclear Russian plant informed him of an infection. The staffer said their nuclear plant network which was disconnected from the internet was badly infected by Stuxnet. So unfortunately these people who were responsible for offensive technologies, they recognize cyber weapons as an opportunity. Stuxnet had infected the internal network of a Russian nuclear plant, exactly in the same way it compromised the control system in Iranian nuclear facilities in Natanz. Thats happening despite cyber threats being well known, and various security solutions are able to neutralize it. Scada Pdf TutorialStuxnet infected the network within a Russian nuclear plant isolated from the Internet. Attackers probably used as USB or mobile devices to spread the malware. Russian Intelligence agencies in the past have already observed this infection mode to cross a physically separated air gapped network. Windows 8 Pro X64 Activator Technique. For example, Russian astronauts had carried a virus on removable media to the International Space Station infecting machines there, according to Kaspersky. NASA has confirmed that laptops carried to the ISS in July were infected with a virus known as Gammima. AG. The worm was first detected on Earth in August 2. Nasa said it was not the first time computer viruses had travelled into space and it was investigating how the machines were infected. I mentioned the Stuxnet malware because its considered a case study. The malicious agent is so notorious, its still able to compromise networks and control systems within critical infrastructure.
