Basic information of bigdata

What is Big Data?

Data provides information. Accumulation of information is equivalent to accumulation of power and achieving more control over the related events and results. Enormous volume of data with diverse nature is generated In the modern world  that storing them and analysing them to get the required output had become a big challenge. The data could be anything from a real time transaction, climatic conditions, clicks on computers, mobile logs, posts or tweets from social media and much more. If the data so collected becomes impossible for a single machine store and process then such data could be named as Big Data.

Data which are very large in size is called Big Data. Normally we work on data of size MB(WordDoc ,Excel) or maximum GB(Movies, Codes) but data in Peta bytes i.e. 10^15 byte size is called Big Data. It is stated that almost 90% of today's data has been generated in the past 3 years.

IoT Eco System and IoT Gateway security



Cybercriminals have an array of potential attack vectors to choose from when targeting IoT implementations. Here’s how to work towards comprehensive security in Internet of Things applications.
The Internet of Things may have a significant economic potential, but it also gives malicious actors an ever-expanding toolbox for cyber attacks. Gartner estimates that 5.5 million “things” get connected each day. It’s no wonder that hackers are beginning to target IoT devices with weak security for botnets and other attacks: they are often low-hanging fruit.
As both physical and digital threats increase, the need to find technologies to reduce such risks is also rising. This article will discuss the vulnerable points in an IoT application and the key strategies to resolve them, including details on maintaining supply chain integrity. It will also cover the fundamental elements needed to create a robust security paradigm.

Potential attacks for IoT applications

A handful of IoT-related attacks seem to receive the most attention in the popular press. There is, of course, the Mirai botnet that brought down a chunk of the internet last year. There’s BrickerBot, which renders insecure IoT devices unusable. On the industrial side, Stuxnet is famous for causing physical damage to nuclear centrifuges in Iran. And then there is BlackEnergy — a malware variant that shut down a portion of Ukraine’s power grid.
Attacks with a physical component: IoT attacks at the physical layer of the OSI Model require unauthorized access to physical sensing, actuation and control systems. Consider how electronic car theft works as an example. Since cars are essentially computers on wheels, hackers have a variety of options at their disposal. They can clone the radio signals from a key fob to open a locked vehicle. A hacker with physical access to a vehicle’s Controller Area Network (CAN) bus underneath the steering wheel can cause all sorts of mischief: They can unlock the car’s immobilizer that stops a thief from driving away and reprogram a new key for the vehicle. Access to the CAN bus could also enable them to hack the speedometer, door locks and other components.
The similar threat applies to industrial control systems, which have a decades-long history. Many industrial machines make use of supervisory control and data acquisition (SCADA), a technology that was created decades ago without much thought about security. As a result, an attacker with physical access to a SCADA system can cause significant damage to industrial facilities and critical infrastructure.
Similar threats could apply to medical devices. An attacker could gain access to an implantable device such as a cardioverter defibrillator or an external medical device such as an insulin pump to install malware.
Pure software attacks: This category includes malware variants such as viruses and trojans and worms. Also in this category is fuzzing, in which random data is thrown at software to see how it reacts. Distributed Denial of Service (DDoS) attacks can be software-based as well, although they can also occur at lower levels of the OSI Model. One potential example of an IoT-related DDoS risk would be safety-critical information such as warnings of a broken gas line that can go unnoticed through a DDoS attack of IoT sensor networks.
Network attacks: One of the biggest vulnerabilities of IoT devices is their wireless connectivity, which can make them remotely exploitable. Here, there are a variety of possible attacks that are possible on the devices, or “nodes,” connected to the network.
In an enterprise Internet of Things context, those nodes typically communicate with the gateway that is the core of that implementation. The node connects all of the IoT devices to the cloud.
Let’s assume that we have an industrial IoT application with interconnected gateways linked to each other in a mesh network. If a hacker jams the functionality of a gateway with denial of service requests, they can bring down the whole IoT project. Thus, a single attacker can stop the IT and OT elements of a system from interacting, as we discussed in the article “IoT gateway architecture: Clustering ensures reliability.” 
Cryptanalysis attack: In this type of exploit, a hacker tries to recover an encrypted message without access to an encryption key. Examples include brute-force attacks when a hacker tries every possible password combination to gain access to a system. The known-plaintext attack, with roots stretching back to WWII, is another example, in which a hacker has access to unencrypted text as well as its....Continue reading

curious case of AI in the cloud


Data is not the new oil as some have claimed, and Machine Learning is not the new electricity. The shift is so gigantic that itâ??s impossible to come up with a fair analogy


We're living through the most significant technological shift in human history. Our smartphones are connected to thousands of computers and access terabytes of data, and whether we realize it or not, our lives are heavily impacted by algorithms- our news feeds, the products we buy, our food, our transportation, etc.
The shift is significant, not so much because we have access to unlimited computational power and data, but rather, because a larger number of things is now measurable.
The confluence of unlimited computational power and unlimited data, in conjunction with continuous advances in algorithms and hardware, mean that Machine Learning (ML) is the driving force of this major technological shift - and that is significant because computers will play an increasingly important role in our decision-making and ML in how the technology works.
On one hand, measuring at scale allows Machine Learning algorithms to make better predictions which help individuals and businesses make decisions. On the other hand, it feeds the improvement of algorithms that perform tasks that are better suited to computers.
Given the quickly evolving landscape, how can developers and businesses, old and new, best capitalize on this shift to have an impact and stay ahead of the game?
First, it's important to separate hype from reality. We won't have human-like robots walking our streets and performing the very hard jobs that require "soft skills" anytime soon, but AI and Machine Learning are here to stay and they are the new reality of computing.
Data is not the new oil as some have claimed, and Machine Learning is not the new electricity. The shift is so gigantic that it's impossible to come up with a fair analogy. What is clear, is that every business in the very near future will use ML and every developer will work on ML as part of a standard set of computing tools. That's a reality today for those that have embraced it.
Second, understanding the ecosystem is critical. The Cloud plays a significant role because it gives developers and businesses access and flexibility in storing as much data as needed, and in instantly scaling as needed, at low prices - size doesn't matter.
Individual developers, small teams, mid-size, and large enterprises can all leverage the Cloud and AI. And it also means that consumers, in many verticals, will continue to expect competitive performance and free or near free functionalities. So, we have the technology (cloud, data), businesses (every business becomes a tech business), and consumers (the "end point" for collection of data and impact).
Third, identifying internal opportunities and modifying processes is pivotal in driving that shift. For developers, it means getting up to speed on ML and understanding the subtleties of what different algorithms offer. For medium-sized companies, that's having a strategy to collect the right data, and execute on it, step by step. For large companies, it's ensuring that data pipelines and processes align with experimentation and leverage AI. In all cases, it's having clarity on what needs to be measured so that the right metrics are in place.
It's also important to avoid pitfalls, and there are many. On one extreme sit the skeptics that think AI does not apply to them because they're very far from being able to apply it. This is usually a misguided notion, as the Cloud and many open source tools allow fairly quick starts. Additionally, in most cases, data is already in existence in one form or another. On the other extreme sit the dreamers who believe that AI and the Cloud will magically solve everything.
In practice, the biggest challenge most companies face is not having the right expertise. For developers, learning ML has become increasingly accessible, but a common issue is a disconnect between those with the technical skills and those with the business experience. The reality is that no matter what stage you are in - as a developer, or as a company - the time to embrace AI is now.
AI can be applied anywhere where you can collect data, measure, and make predictions. Identify those opportunities and tie them to a specific customer or business needs and start ensuring the quality of the data is good and apply basic methods to start with as a proof of concept. This includes asking the right questions. Then, look to the Cloud because it gives you the flexibility to easily, quickly, and cheaply try things out, and identify the right open source and learning resources available.
In this process, keep in mind what three factors above: separate hype from reality and set reasonable expectations; have a clear understanding of the technology (cloud, data), the business, and the "customers" for the task, and have clarity on what is to be measured and what the goals are.
If you manage to put these things together and get started, even with a small project, you'll already be participating in that gigantic shift. Just be sure to have clear goals, iterate, and experiment.
