Security threats in IoT
Different types of security attacks in Internet of Things
1. Cloning of Things
Cloning is making the similar physical and behavioral copy of existing thing. Cloning of things in Internet of Things is making the device that holds the exact behaviors of the existing device in the market. By cloning things any manufacturer can make things and include the properties of the things like physical configurations or behaviors. In Internet of Things devices interact with humans as well as other devices to share the information. If the cloned device is programmed to pass the user sensitive information to the untrusted servers, it may cause serious problems to the user. So when buying the devices users should verify the manufacturer of the device for security purposes. The manufacturers have to find a way to securely transmit the data to only trusted device by some verification methodologies like authenticating the users to access the web.
2. Malicious substitution of things
Malicious substitution of things is replacing the trusted things with untrusted things that may cause information loss. Identity loss is one of the biggest problems with the internet. A malicious company may manufacture a thing that looks and behaves similarly as the things made by other trusted company which may cause the loss to belief the customers have on the company. The malicious things look and behave similarly like the real ones. The user is not aware of the actions that are going on the server side, so if a user finds something wrong with the device he may loss trust on the real manufacture of the device.
3. Eaves Dropping attack
Eavesdropping is listening to the private conversations or private messages that are not intended for this device. A device may listen to another network of devices that are communicating within themselves. In IoT, devices within our home interact with each other and will communicate with the server. So if an untrusted device is fixed in the home it will not only listen to the messages that are intended to it but also to all the messages. This problem may be reduced by having different routers for the communication. Using different ports for internal and external communications reduces the risk of eavesdropping of messages. Manufacturers should have a protocol to protect the messages being listened by the untrusted devices. To protect customers, manufacturers should have a protocol like cryptography in which the messages are encrypted at the sender side and only the legitimate receiver can decrypt the messages.
The ability to record information which is relevant to a product and service will help ensure an exceptional customer experience. The ability to access this information anywhere in the world is also key to supporting the customer. (http://www.cio.com/archive/ec_blueprint.html) Wireless devices such as laptops,
Asymmetric Encryption is used to protect the data while in movement. Asymmetric Encryption is also known as Public Key Encryption. It uses two related keys, a public key and a private key which is not shared with anyone. This pair of keys are developed by mathematical methods which can be solved in one direction. So anyone can encode a data using the public key but only the user with a private key can decode that specific data. The length of Asymmetric Key Encryption is normally 1024 or 2048 bits. However, in Asymmetric framework the keys with smaller than 2048bits are considered as not safe to use.
Cloning is a popular topic of discussion on college campuses. There is research carried on in cloning in almost every part of the globe. The future of cloning looks very bright as the scientists are constantly progressing by leaps and bounds. However, it is not quite sure whether the future of cloning will help mankind or be the cause for its destruction.
Cloning is a process by which genetically equal organisms are created with the same DNA. In simplest terms, clones are like twins born at different times. This procedure poses various dangers to society and humankind. One of the greatest threats this procedure creates is among
If we take an example, people are more concerned about paying their bills over the phone by their credit card, knowing that there might be someone in the middle intercepting all this information to harm the person. This action has a lot of side effect in the development of new technology. Paying over the phone using a credit card was never there years ago; it used to be only paper bills. Now, not only can we pay though phone call but also we can pay using the computer. All this is new technology that was never there. But if someone is always doing something illegal to affect the direct communication of customer and sellers, there won't be a trust with will be a great bondage between them, which can help the market, and the technology to go to another lever, which is better.
With the increasingly ubiquitous nature of mobile devices and online availability, including smartphones and tablets, there is also an understandable concern about the level of security that is afforded to such devices. This can be considered as increasingly important given the proliferation of policies such as BYOD (Bring Your Own Device) which is being used by diverse organizations as a way of lowering the cost of ownership for such devices while also leveraging the flexibility advantages that their utilization can bring. It is therefore an area of immense interest due to the changing and emerging nature of both the technology itself as well as the security concerns.
I will be searching about the Security Risks of Mobile Phones, Expanding on them, how they affect us and what we can do to prevent them. “About 75 percent of the world has Mobile Phones”. I will be searching how it affects their everyday life. I will also talk about different Mobile Phones and what kind of risks they contain. It is a Vast and broad topic which requires a lot of Research. I will be searching different sites to make sure that I have
The ability to conduct warfare through technological methods has increased information security awareness and the need to protect an entity's infrastructure. Subsequently, cyber warfare produces increased risk to security practitioners that employ technology and other methods to mitigate risks to information and the various systems that hold or transmit data. A significant risk to information lies in the conduct of electronic commerce, hereinafter called e-commerce. E-commerce is the purchasing or selling of goods and/or services through the internet or other electronic means (Liu, Chen, Huang, & Yang, 2013). In this article, the researchers will discuss cyber warfare risks, present an evaluation of established security measures, identify potential victims of identity theft, and present an examination of the security of e-commerce companies....
An attacker looks for poorly configured network devices to exploit. Common vulnerabilities include weak default installation settings, wide open access controls and unpatched devices. To gather information from the encrypted network traffic attacker places the packet sniffing tool on the network. Sniffing is the act of monitoring network traffic for data such as clear-texts passwords or other configuration credentials. Usually transmitted information carried along during an Secure SHELL session cannot be seen but other information such as sender’s and receiver’s IP addresses, DNS requests to resolve hostname, port numbers and the amount of data is visible. If the traffic along the network is encrypted by the attacker, the attacker can see which sites are visited, amount of data received and sent and the port numbers used for the connection. Using a simple packet sniffer, all plaintext traffic can be read easily. This becomes possible because of weak physical security or lack of encryption during the process of sendin...
technologies such as Bluetooth and ZigBee which are used to carry the information from perception devices to a nearby gateway based on the capabilities of the communicating parties. Internet technologies such as WiFi, 2G, 3G, and 4G carry the information over long distances based on the application. Since applications aim to create smart homes, smart cities, power system monitoring etc.
Safety of information is the most valuable asset in any organization particular those who provide financial service to others. Threats can come from a variety of sources such as human threats, natural disasters and technical threats. By identifying the potential threats to the network, security measure can be taken to combat these threats, eliminate them or reduce the likelihood and impact if they should occur.
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).
are the only eyes that see it? Also how does a company know an electronic
Simply, any e-commerce done through wireless devices (e.g. mobile phones) over any network especially the internet.
The new age of technology was born late last century in the form of the silicone chip. Since this early invention computers have progressed in leaps and bounds from the very basic early models to the now very complicated and very powerful computers of today. In between this growth the Internet developed into a mega market where billions of dollars are traded daily. It is a place where you can pretty much buy and sell anything you can think of. But with the development of such a powerful tool there are always going to be problems such as pornography, hackers, dodgy chat rooms and authenticity of information. But like with any argument you have to weigh up the good with the bad, the internet provides you with a wealth of information so that you can find out much on many different products, allows businesses to function so much more efficiently, there is also the availability of online learning.
