Blockchain and cloud security

Blockchain made headlines recently as the transaction infrastructure for bitcoin and other cryptocurrencies, but this shared ledger solution is now being reimagined as a way to bridge the enterprise security gap. In fact, 60 percent of companies have already implemented or plan to implement blockchain technology — with 28 percent actively testing solutions and 20 percent in the discovery and evaluation phase. But many challenges remain, including scalability and privacy. The use of blockchain technology as a cryptocurrency record-keeper makes sense. As cryptocurrency markets have cooled and somewhat stabilized, however, interest in blockchain as a security technology has swelled.

5 Ways in Which Blockchain is Improving Cloud Computing

T he development of cloud-based computing changed the game for software developers. For one thing, it rendered limitations related to storage, flexibility, and cost obsolete. It also ushered in a new era of software innovation, enabling the development of groundbreaking cloud-based services like Dropbox and Google Drive.

In recent years, however, a technology with even more innovative potential has availed itself to the developer community: blockchain. Blockchain bears opportunities for developers unseen since the turn of the century. Innovations are considered disruptive when they help companies displace established competitors.

History has seen a number of technologies that qualify as such. The cloud, arguably, was one. The blockchain is another. One reason is decentralized ledgers are simply technologically superior to centralized ones. The blockchain eliminates that concern. On the blockchain, you know your data cannot be secretly tampered with. Not a single cloud vendor can claim the same. Blockchain companies may still operate in niche markets now.

Would applications be processing that much traffic? When designing the Bee Token platform, the questions we asked first were: what sort of capacities might be added to Ethereum in the future? What will we be sacrificing by embracing a totally decentralized model?

Would it be better to fully decentralize further down the road, when the technology can more speedily process transactions? All of the big players in the cloud Amazon, Microsoft, IBM and Google are currently experimenting with blockchain backends. They see the practical sense in it, and they see the inherent value of a more democratized, decentralized reality.

The similarities between the two platforms will enable those with experience in cloud to make an easy transition into blockchain. But more importantly, making the switch is a smart move for the longevity of your career as a developer. Innovation creates opportunity. And the future will belong to those who capitalize on the opportunities availed by decentralized networks.

Securing Cloud Based Data Storage using Blockchain

Due to the high amount of electronic health records, hospitals have prioritized data protection. Because it uses parallel computing and is distributed, the security of the cloud cannot be guaranteed. Because of the large number of e-health records, hospitals have made data security a major concern. The blockchain BC has been deployed in the cloud to preserve and secure medical data because it is particularly prone to security breaches and attacks such as forgery, manipulation, and privacy leaks. An overview of blockchain BC technology in cloud storage to improve healthcare system security can be obtained by reading this paper. First, we will look at the benefits and drawbacks of using a basic cloud storage system.

Blockchain vs Cloud Computing: Difference Between Blockchain and Cloud Computing

Journal of Cloud Computing volume 10 , Article number: 35 Cite this article. Metrics details. Through virtualization and resource integration, cloud computing has expanded its service area and offers a better user experience than the traditional platforms, along with its business operation model bringing huge economic and social benefits. However, a large amount of evidence shows that cloud computing is facing with serious security and trust crisis, and building a trust-enabled transaction environment has become its key factor. The traditional cloud trust model usually adopts a centralized architecture, which causes large management overhead, network congestion and even single point of failure. Furthermore, due to a lack of transparency and traceability, trust evaluation results cannot be fully recognized by all participants. Blockchain is a new and promising decentralized framework and distributed computing paradigm.

Addressing Security and Privacy in Cloud Computing: Blockchain as a Service

A successful cyber-attack can be the downfall of any well-positioned business. Data breaches not only cause significant financial losses but are also the leading cause of a bad reputation for victim companies. Blockchain started out as the technology behind Bitcoin but has popularly grown into a promising mitigation technology for cybersecurity. What is Blockchain 4. Use Cases of Blockchain for Cybersecurity.

Blockchain for Cybersecurity: Pros and Cons, Trending Use Cases

Although a lot of work has been done in the domain, tasks scheduling and resource allocation in cloud computing remain the challenging problems for both industry and academia. Security in scheduling in highly distributed computing environments is one of the most important criteria in the era of personalization of the cloud services. Blockchain became recently a promising technology for integration with the cloud clusters and improvement of the security of cloud transactions and access to data and application codes. In this paper, we developed a new model of the cloud scheduler based on the blockchain technology. Differently to the other similar models, we tried to offload the implementation of the blockchain modules. The developed model has been experimentally simulated and validated by using the new original cloud simulator.

Blockchain Security

The same blockchain technology that can enhance security for cryptocurrency could also revolutionize cybersecurity, according to the Cloud Security Alliance. For an increasing number of enterprises, cloud has swooped in as the latest superhero of IT security. Reavis believes the same blockchain technology that can enhance security for, say, cryptocurrency or supply chain management—an immutable, shared, transparent ledger of authenticated ownership, identity and transactions—will also revolutionize cybersecurity. But researchers are starting to explore blockchain for cloud security. The Koreans did note one potential risk, however. To prevent this, they recommend a model that would not only install a new electronic wallet for each blockchain transaction in the cloud, but delete that wallet after each completed transaction. Since I have neither the expertise nor the space to paraphrase the technical details of that here, you can find out more in their report , complete with diagrams. Getting back to Reavis, his organization, the CSA, has formed its own working group on research and technical development specs for blockchain security applications in the cloud.

Through blockchain, Roberto Galoppini sees an opportunity to kill two birds with one stone: His organization, FileZilla, can offer users free online data storage while also allowing them to earn valuable cryptocurrency. Galoppini, director of strategy for FileZilla , the popular, open-source FTP client, said his service is planning to shift direction this year by using a peer-to-peer P2P , distributed storage platform from Atlanta-based Storj Labs Inc. FileZilla, which has been piloting the Storj decentralized storage for several months, had been making money through its free file-sharing service, which is hosted on SourceForge. It pitches users third-party software or offers to let them make money by testing a new web or mobile application. In turn, FileZilla would share revenue with the third-party software vendors. Some users, however, reported adware was being installed without consent, and in general, the advertising isn't always popular with users, Galoppini said.

In the area of Cloud security, there are many scenarios where it faces many threats and challenges for effective cloud services. Cybercrime nowadays poses major threat to the Cloud users. It leads to the situation for preserving security over cloud computing and its service provisioning. Intruders find different ways to attack the cloud data.
