 internet of things and problems facing connectivity

Introduction.

With the rapid growth in technology, the network industry has grown. The information-sharing has become easy since there is diverse connectivity of devices. Data storage is also easy and useful in recent days. This has resulted from the invention of machines like cloud computing machine, which can hold a massive amount of data for an extended period. Arguably internet of things has also brought considerable connectivity in data sharing. IoT comprises of intricate networks which often share information through the internet. The devices are connected everywhere, and the message can be received at any place. However, data can be lost or distorted if the device is hacked. This paper aims to analyze the internet of things and problems facing connectivity.

Problems Facing IoT

Many issues are facing IoT operations. Internet of things connects many devices and information can be shared widely among people. This makes communication easy and reliable. This is because data can reach many people within a short time. However, IoT is faced with many challenges, for example, sinkhole and hello flood attacks. In the sinkhole attack, malign nodes win overall joining nodes and pass the information to the malicious device (Beckett et al., 2017). In this case, the info lands to unauthorized hands. On the other hand, hello flood attack is a type of DoS attack which degrades the performance of the nodes, therefore, inhibiting proper delivering of the message.

Other assaults related to IoT include Sybil, selective forwarding, and warm hole attack. In the warm hole attack, an assailant’s node creates a tunnel between the real node (Beckett et al., 2017). Afterwards, the assailant node starts forwarding information as an actual node. The malicious node will, therefore, claim that there must be a problem in the bottom station.  The malign nodes can also convince the acting ones that they are friends or rather they work together. In selective forwarding attack, the new node acts as an even node and drops a few packets selectively. Sybil attack contains nodes with a couple of identities. These identical nodes gain influence on the existing nodes.  Sybil attack can also be explained as a kind of security threats in a computer device, whereby a person tries to create multiple accounts.

Solution

It is crucial to develop protective strategies to minimize IoT assaults. In the following paragraph, we have seen several attacks associated with the internet of things. Any attack to a device brings negative impact to the information stored. This is because the data can either be stolen or distorted. In this paper, the solution offered is having a node to detect all malicious nodes. Malicious nodes can tamper with packets and therefore making the final information invalid. The number of packages sent may also not reach the receiver. Coming up with a node to detect malicious nodes is consequently crucial (Aborujilah & Musa, 2017). This will help the server to recognize any malicious node that tries to tamper with the system.

Conclusion.

To sum up, IoT (Internet of Things) connects many devices in a different place. Therefore, information can be shared by people in different areas. However, various challenges are facing the internet of things. These are attacks which pause security threats to a computer system. The attacks include Sybil, warm hole, selective forwarding and hello flood attack. In these attacks, a malicious node is introduced to the computer system and inhibits the normal functioning of the device. The solution offered in this paper is developing a node that can identify all malicious nodes.
