Blockchain technology, or distributed ledger technology (DLT), as it is alternatively often called, is one of the hottest topics in the technology sector as of now. A blockchain is a specific type of distributed ledger that stores data in blocks that are linked together via a cryptographic signature function.
This, in short, works by always using the signature of the last block plus the data of the current block to sign the current block. Given enough computing power behind creating the hash signatures for new blocks, a process that is known as mining (PoW), the resulting public ledger is virtually unmodifiable for malicious actors, commending itself for applications that rely on mutual trust where trust cannot be easily applied.
Blockchain technology is gradually revolutionizing the way business is being transacted on in the digital realm. Blockchain technology exploits decentralisation and one-way cryptographic hashes to ensure the integrity of data and P2P transaction across the internet. Cryptocurrencies have been the main driver of Blockchain technologies and although the world may have slowed down in terms of its appetite for these currencies, the technology behind Bitcoin and EOS is finding relevance and applications in diverse areas. This because unlike other technologies that focus on solving specific problems or automating processes where security becomes an afterthought, Blockchain in many ways cooperates security by design in its architecture. It eliminates the need for third-party layering of security elements (TNO 2019). This article explores areas where Blockchain technology is finding novel applications. These include identity management, creative content copywriting, tokenization of products and data integrity management.
Information security aspects when moving operations from on-premise
So if you are reading this I will make some basic assumptions that you know about Microsoft Azure, Amazon Web Services and perhaps even Alibaba Cloud, these are renowned hyperscale cloud vendors. Last few years cloud computing have been among the IT industries hottest topics. The term refers to on-demand access to computing resources provisioned by another provider. 2019 has been dubbed the year of migrations by several vendors and a pronounced advantage of cloud computing is that they tend to be highly available and easily scalable. For fast-growing business, cloud-computing has revolutionized the way they can work. Organizations typically lease cloud-based resources from outside the organization. Of course, it is also possible (but not as common) to host cloud-based services internally.
While cloud computing can be very cost-efficient and offer fast scaling, it’s challenged by the fact that resources will most likely be hosted outside of the business’ data centre and therefore, outside of the direct control of that business, increasing the complexity to manage risk and handle governance.
