Directions (1-10): Read the following passage carefully and answer the questions given below it. Certain words are given in bold to help you locate them while answering some of the questions.
Paragraph 1: India’s ambitious Smart Cities program focuses on the need for the computer systems enabling smart cities to have an open-source system infrastructure in order to make them efficient in collaborating with the various intelligent platforms that will run the smart cities via a smoothly functioning network, which will allow for cooperation among disparate civic bodies within a city. India is not alone in this ambitious initiative. Municipalities over the world have realized how valuable it can be to make their cities “smarter”. Smart City initiatives across the globe will attract technology investments of more than $81 billion in 2018, and spending is set to grow to $158 billion in 2022, according to the International Data Corp. (IDC). Singapore, Tokyo and New York City will be among the largest spenders. Serena Da Rold of IDC has been quoted as saying that intelligent transportation and data-driven public safety remain the largest investment areas, but that IDC is also finding significant pockets of spending and growth in back-office and platform-related use cases, which are less often publicized, but increasingly happening behind the scenes in cities around the world.
Paragraph 2: The opportunity to make money in installations like these does not lie in a closed, monolithic implementation, but is facilitated by an open system with the ability to easily add new services, applications and sensors. In such a model, it is not just the connections from application to application that are open. Every aspect of the enabling infrastructure is open, including its internal schema and interfaces, and the entire programming “source” code of the implementation is also made available on a royalty-free basis. People are well aware of the vulnerabilities personal devices such as smartphones, laptops, routers and other hardware have, and the firms that make them work hard to plug gaps in a never-ending catch-up game with hackers. An entire sub-industry has been spawned for companies such as Symantec Inc., which owns Norton, the antivirus and anti-malware firm. It turns out that while firms that are involved in the smart cities program stand to make more money as they roll out new sensors, each with an Internet of Things (IoT)-based connection to their own application, as well as to other related smart cities applications, the weakest link in smart cities installations may also actually lie at this sensor level.
Paragraph 3: According to Wired magazine, researchers from IBM Security worked with their counterparts from security firm Threat care to investigate sensor hubs from three different companies, Battelle, Echelon Corp. and Libelium, who sell systems to support smart cities installations. The researchers found that these sensor arrays are at great risk of being hacked. These firms’ business is to set up an interconnected array of sensors and allow municipalities to use IoT information from these sensors to solve problems of coordination between various city agencies. These sensors monitor a variety of factors, such as pollution and traffic flow, and can automatically cause action at the ground level by controlling functions such as traffic lights, street lighting and emergency alerts. The magazine cites the instance of the false alarm that went off earlier this year in Hawaii about an expected missile attack as an example of such an accident. This particular false alarm was enormously stressful, coming as it did in the wake of sabre rattling by North Korea about its ability to hit US cities with its expanded nuclear missile capabilities.
Paragraph 4: The three firms have confirmed the vulnerabilities and issued patches for all the bugs. The magazine stated that researchers have confirmed none of the bugs their “white hat” or friendly hacking efforts exposed have actually been exploited by others with mala-fide intent. That said, officials in many countries, including the US, have acknowledged that their infrastructure is vulnerable, and it isn’t just the ballot box that the bad guys are coming after. For instance, Russian hackers have long been suspected of causing widespread electricity blackouts in the Ukraine. Municipalities would do well to earmark some of those billions of dollars to focus on ongoing spending on security, much as corporations and individuals spend money on antivirus and anti-malware shields for their devices.

Solutions:
S1. Ans.(e)
Sol. Option (e) is the appropriate choice here. The answer can be referred from paragraph 1 where it is given that intelligent transportation and data-driven public safety remain the largest investment areas, but that IDC is also finding significant pockets of spending and growth in back-office and platform-related use cases, which are less often publicized, but increasingly happening behind the scenes in cities around the world.
S2. Ans.(d)
Sol. The correct choice here is option (d).For the answer ,both the paragraph 2 and 3 have to be referred. As paragraph 2 states about the how the weakest link in smart cities installations may lie at this sensor level. The level is mentioned in paragraph 3 which is the researchers found that these sensor arrays are at great risk of being hacked.
S3. Ans.(c)
Sol. Option (c) is the correct choice. The answer can be deduced from paragraph 2 where it is mentioned that smart cities program stand to make more money as they roll out new sensors, each with an Internet of Things (IoT)-based connection to their own application, as well as to other related smart cities applications .IoT is the network of physical devices embedded with electronics, software, actuators, sensors and connectivity which enables these devices to connect and exchange data and signals.
S4. Ans.(b)
Sol. The most suitable choice here is option (b).This line is quoted in bold in paragraph 2 which states that people are well aware of the vulnerabilities personal devices such as smartphones, laptops, routers and other hardware have, and the firms that make them work hard to plug gaps in a never-ending catch-up game with hackers.
S5. Ans.(c)
Sol. Only option (c) stands out as the suitable choice for the answer. The answer has to be deduced and concluded from paragraph 4 based on the author’s statement that the vulnerabilities exposed to the bugs have been confirmed by the researchers that none of the bugs their “white hat” or friendly hacking efforts exposed have actually been exploited by others with mala-fide intent. This means that white hat are the friendly hacking efforts which are not exposed by mala fide intent.
