The internet of things (IoT) is the internetworking of physical devices, vehicles (also referred to as "connected devices" and "smart devices"), buildings and other items—embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data.
3. Security concerns and vulnerabilities
“Yet as we connect more and more devices to the Internet, everything from the thermostat to the toilet to the front door itself may create a potential new opening for electronic intruders.” – MIT Technology Review, August 2013
• Data about usage can reveal whether a person is present at home or not
• Automated home system can be cracked into, allowing intruders entry into the home
• Video feeds of homes allow attackers access to private information about individuals
3.1 IoT Security: trends, problems and challenges
3.2 Security and Privacy Challenges for the Internet of Things
3.3 Unique Challenges for IoT Security
• IoT relies on microcontrollers with limited memory and computational power o This often makes it impractical to implement approaches designed for powerful computers o This in turn requires constrained IoT devices to be hidden behind secure gateways
• Threats based upon gaining physical access to IoT devices
• How to bootstrap trust and security, and ways that this can unravel
• Evolving technology o More powerful Systems on a Chip (SOC) embedding hardware security support o Ecliptic Curve Cryptography with reduced computational demands
• Anything that is exposed to the Internet must be securely software upgradable
• User experience must be good enough to avoid becoming a weak link in the chain
• The necessity of keeping up to date with security best practices

Virtualization-based security agent: Hypervisors in virtualized environment are widely used to enforce security policies transparently on enterprise and cloud applications in enterprise IT and cloud computing environments.
Gateway-based security agent: When security cannot be added to an endpoint, as is the case for legacy systems, a security gateway or bump-in-the-wire implementing the security agent function as a physically separate network node can be deployed to secure these type of endpoints and their communications. Because the security agent is not physically on the same endpoint that it protects, advanced security functions such as secure boot attestation or application whitelisting in that endpoint cannot be easily implemented.
In 2010, former senior U.S. officials conducted a simulation imagining of a catastrophic cyber attack, the origins of which came by way of a mobile application having malware that was self-replicating that eventually overwhelmed wireless networks and disabled portions of wired network communications and the internet as well as curtailing electrical supply channels and oil and gas pipelines (Corbin, 2010). Rather than consider the likelihood of such a catastrophe, the panel took the position that if such an event were to occur the government would have to take over telecommunications in this country, eight-five percent of which o...
Business ventures can benefit from virtual firewalls to protect access and data at lower costs than traditional methods. It is also beneficial to have an experienced security professional who is aware of your security needs. Virtual security involves the use of advanced controls such as a virtual switch to protect against malicious attacks coming from unverified sources. Applications are isolated to make them untouchable by malware, viruses and even applications that may stop execution (Marshall, 2011).
The Internet of things is a trend where everyday objects have network connectivity, allowing them to send and receive data. It depends on a great deal of data to function as devices are being setup to track and collect data. (Mohn, 2016) E.g. smartphones, online banking, home security systems etc. As these are important to us, we can’t over look how crime will play a vital role and affect lots of people due to its popularity and the fact that it will be a part of lives as we grow technologically.
It is about the ability to deliver any information to any device over any network. In short, it is about computers everywhere where computers are embedded into equipments , machines , furniture or people. Portable devices, wireless communication and nomadic or ubiquitous computing systems.
Ever since day one, people have been developing and creating all sorts of new methods and machines to help better everyday life in one way or another. Who can forget the invention of the ever-wondrous telephone? And we can’t forget how innovative and life-changing computers have been. However, while all machines have their positive uses, there can also be many negatives depending on how one uses said machines, wiretapping in on phone conversations, using spyware to quietly survey every keystroke and click one makes, and many other methods of unwanted snooping have arisen. As a result, laws have been made to make sure these negative uses are not taken advantage of by anyone.
Ultimately the end users turn out to be the weak link in the security chain as they ignore the latest security trends and install outdated devices that do not support the latest security features. An example would be that of an outdated wireless router that does not support WPA encryption. By proposing a simple solution that lets the users configure their wireless access points for best possible security, the problem can be nipped in the bud.
cultivation control and precise irrigation. IOT also brings great convenience to forestry, especially in the forest identification, wood tracking management and so on.
Virtualization technologies provide isolation of operating systems from hardware. This separation enables hardware resource sharing. With virtualization, a system pretends to be two or more of the same system [23]. Most modern operating systems contain a simplified system of virtualization. Each running process is able to act as if it is the only thing running. The CPUs and memory are virtualized. If a process tries to consume all of the CPU, a modern operating system will pre-empt it and allow others their fair share. Similarly, a running process typically has its own virtual address space that the operating system maps to physical memory to give the process the illusion that it is the only user of RAM.
Ubiquitous computing (ubicomp) strives at creating a completely new paradigm of computing environment in almost all of these respects. Ubicomp systems aim for a heterogeneous set of devices, including invisible computers embedded in everyday objects such as cars and furniture, mobile devices such as personal digital assistants (PDAs) and smart phones, personal
In addition to this we can also monitor user behavior in the cloud “because user’s identity is proved by user’s personal key and this mechanism is integrated in the hardware, such as the BIOS and TPM, so it is very hard to the user to make deceiving for their identity information”(Dawson, 2010).using this mechanism
The Internet of Things (IOT) is a system of interconnected computing devices, mechanical and digital machines, and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. The IOT creates an opportunity to measure or monitor a large
The Internet of Things (IoT) is the network of physical objects accessed through the Internet. The Network of interconnected objects harvests information from the environment (sensing) and interacts with the physical world (actuation/command/control), uses existing Internet standards to provide services for information transfer, analytics, applications and communications (Jiong et al. 2012).
Most people do not understand the sheer costs of creating a safe Internet experience. There are costs for personnel, and the latest security and software, with any system we use. These costs can greatly impact someone’s internet browsing experience. Most people expect Wi-Fi to come freely or cheaply these days. What people don’t understand, though, is that when you cut into that budget for internet services, you are also cutting the cost of the security
IoT network architecture has three layers.First layer is the sensing layer which collects data from different sensing devices. Next is the network layer which transmit and process the information. Different specific IoT applications are supported by the last layer i.e. application layer.
A critical part of network planning involves setting up of security mechanisms. Deploying the network with security configuration provides superior visibility, continuous control and advanced threat protection across the extended network. Additionally, security procedures define policies to monitor the network for securing critical data, obtain visibility, mitigate threats, identify and correlate discrepancies.
