Cybersecurity Tech Basics: Blockchain Technology Cyber Risks and Issues: Overview | Practical Law


In the last few years, the major concern is about moving to the online world safely. The unauthorized access of data, program among the network is quite common. In spite of using various conventional ways of protecting online data, still, hackers are smart to intrude into the network.

Figure 1 shows the traditional way of protecting online data against the cyber-attacks. By looking at some of the recent cyber-attacks it seems like things get only worse day by day around the world. A very high level of dependency on the internet platform only leads to these types of cyber-attacks. Centralization of control, lack of integrity information that we are getting, the trust of quality in data is also some of the problems that need to be addressed.

The reason for the existing cyber-attacks is because they are partially decentralized. Implementing blockchain technology would fully decentralized DNS; the contents in the chain are stored in a large number of nodes making it nearly impossible for hackers to attack. This chapter is an overview of how blockchain works and how can it is used to improve the online security of any application. A blockchain is a constantly growing ledger that keeps a permanent record of all the transactions that have taken place, in a secure, chronological and immutable way.

Nakamoto, A blockchain is a ledger where it keeps track of all the transaction made permanently. It is recorded permanently Nakamoto, As shown in figure 2 a group of the block together forms a blockchain network.

Each block contains basically three values,. The Hash values for each block are generated using the hash function. The hashing technique is explained briefly in the upcoming section. In a blockchain, if a node needs to update a particular piece of data in a transaction to a block, it has to add a new transaction on top of the previous transaction on the block.

Since even a small dot or comma gets added to the data the hash value gets changed. Using this technique, it is easy for the system to detect which block contains incorrect or false data.

Abstract The information in any real-time application is needed to be digitalized across the world.

Since digitalization of data happens, there comes the role of privacy. Blockchain could address the security challenge that happens in the any real sector. There are a few more challenges that prevail in the industry such as integrity in data, traceability of stored records, and interoperability among organizations that share information.

This chapter says what blockchain is and applications in which blockchain technology could solve the existing challenges where they lack security, privacy, integrity, and interoperability. Chapter Preview. Figure 1. Traditional Techniques used against the cyber threat. Figure 2. Creation of a blockchain network.

Knowing that nobody can be trusted, we have built various institutions and created rules that are supposed to help us communicate in a way that can provide a certain level of security over personal paranoia. But then, courts still exist; therefore, the problem does, too. Take into consideration the fact that what we know about blockchain is knowledge accumulated in just over 10 years of selective use. Still, many would mistakenly regard it as if it were solely related to cryptocurrency, and fail to see the full potential it offers.

In the last few years, the major concern is about moving to the online world safely.
