A Smart Grid is a collection of digital systems that is fast replacing the antiquated mode of power distribution. As the latest in technological evolution, several companies and governments are adopting it. Smart Grids help combat global warming by controlling emissions and, consequently, lead to a more sustainable living. This is an added incentive for companies promoting sustainability initiatives while at the same time reaping its technological and business benefits.
Despite its obvious technological and environmental benefits, possible deterrent towards embracing Smart Grid could be that they throw up some security and privacy concerns; concerns that could potentially make companies hesitant in adopting the Smart Grid. These issues have given birth to several stringent security regulations. For example, The North American Electric Reliability Corporation (NERC) avers that power companies "shall use anti-virus software and other malicious software ("malware") prevention tools, where technically feasible, to detect, prevent, deter, and mitigate the introduction, exposure, and propagation of malware on all Cyber Assets within the Electronic Security Perimeter." With this increased consciousness of security and privacy contentions, it is up to the provider companies to resolve them effectively so as to stall the concerns associated with the Grid. It is imperative not only to address existent issues but also anticipate problems in the future and develop effective resolutions for the same.
Existing security concerns revolve around questions such as, which authorized entities are allowed to join the network, what actions are they allowed to perform, which users will require validation before they use the grid, how to maintain the secrecy and authenticity at all times, how to prevent the unauthorized modification of data, when and where should resources be made available, how can system activities be reconstructed, reviewed and traced to specific users, so as to ensure accountability and more on similar lines. Many providers, including Wipro’s AMI and Security Smart Grid framework, are addressing these issues. However, the question still lingers about the security concerns that are poised to plague us in the future, both long term and short term. What can we anticipate and what can be resolved now? Who will take on this challenge? These are just some of the questions that demand response.
