A STUDY ON ADOPTION OF BLOCKCHAIN TECHNOLOGY IN CYBERSECURITY

Department

Abstract - Since Satoshi Nakamoto published white Paper on Bitcoin in 2008, blockchain has (slowly)became one of the foremost mentioned strategies for securing data storage and transfer through decentralized, trust-less, peer-to-peer systems. This analysis identifies peerreviewed literature that seeks to utilize Blockchain for cyber security functions and presents a scientific analysis of the foremost often adopted blockchain security applications. In this proposed work, we are introducing blockchain technology in cybersecurity where IOT security, availability and decentralized storage of data and many more applications will be add on into the system. Thus the Intelligence Agencies and Cybersecurity Cell does not face any issues or drawbacks while operating, although cybersecurity is itself a very secure but after introducing blockchain in it, it will be impossible toseize.

Keywords – Blockchain in cybersecurity, roles, uses cases, methodology, making of more secure system.

I. INTRODUCTION

India is home to a population that is unmoving in numerous socio-economic backgrounds. As per the living standards of individuals, a large vary of devices area unit in use - from high-end secured electronic devices to inexpensive mobile phones. This makes it troublesome for authorities to line uniform legal and technical standards to control data-protection. Additionally, digital attainment and awareness among thepopulationisverylow

Cyber-Securityreferstotheactofprotectiveandmaking certain the protection of laptop systems and electronic devices from targeted cyber-attacks, opportunist malware (- viruses, trojans and bugs) or accidental introductionofmalwarebyusers.

So, the main motto of this project is to ensure more secure system which is unbeatable and overcome the drawbacks which was faced earlier. This proposed application of blockchain in cybersecurity will work as decentralized system i.e. it every user will get to know activities and with the help of it, it will notify whenever anyoutsidertriestoinvadeitandifsomehowifinvasion is successful it will be impossible to change aur retrieve the data as each block in blockchain requires a security

key if anyone to tamper it, it will automatically become invalid.

II. OBJECTIVE

Cybersecurity protects both raw and meaningful data, but only on internet-based threats. Organisations implement information security for a wide range of reasons. The main objectives are typically related to ensuring confidentiality, integrity, availability of companyinformation.

The main objective of this proposed work is to enhance cybersecurity by using blockchain technology As we all knowcybersecurityisitself a verysecurednetwork, but at some instances it is not so efficient as any organisationsoranyonecantamperthedataifequipped withtheknowledge.Asresultthedatawillbeinathreat, but by introducing blockchain in it we overcome this issue

Thegoalofblockchainisto permit digital information, to be recorded and distributed, however not altered. During this manner, a blockchain is that the foundation of immutable ledgers, or records of transactions that can’t be altered, deleted or destroyed. Here we minimize the chance to a bigger extent. We also can’t ignore the point that it is decentralized service i.e. nobody should apprehend or trust anyone else. Every user within the network features a copy of actual same datawithinthevarietyofdistributedledger.Iftheuser’s ledger is altered or corrupted in any manner, it’ll be rejected by the bulk of the users within the network. In particular every block within the chain needs a security key,ifanybodytriedtocounterthat,theinformationcan become invalid for the trespasser and can’t operate any more. So, this method ensures most security of the information and prevents any variety of malpractice. This can facilitate the security agencies that’s serves for thenation.

look at the latest implementations of the evolving Blockchain technology in cybersecurity. Second, it’ll check out the strategies available for deploying Blockchaincybersecuritysolutions.The maintakeaways from the research findings will be used to form a discussion on how Blockchain can afford security in today’sITuserenvironments.

Availability: In recent times, cyberattacks trying to impacttechnologyservices availablenesssquare onthe surge with DDoS (Distributed Denial-of-Service) being theforemostcommon types of attacks. However, in blockchain-based systems, DDoS attacks square measure expensive as the assaulter makes an attempt to overpower the network with an excellent variety of tiny transactions. Blockchains haven’t any single purposeof failure that decreasesthe possibilities ofIPbased DDoS attacks disrupting the traditional operation. Information remains accessible through numerous nodes and so full copies of the ledger are often accessed the least bit times. The mixture of multiple nodes and distributed operation makes the platformsandsystemsresilient.

IoT security: As farmuch IoT thinksabout, Blockchain technology stands out due to its ability to unravel measurability, reliability and privacy problems. It allows coordination between devices, furthermore as chase of immeasurable connected devices and process transactions. This is a decentralized approach in which cryptographic algorithms square measure enforced so client information getpleasurefrom biggerprivacy.It’s associate degree approach that eradicates faults and offers a resilient scheme. With the increasing application of AI and IoT, the protection of information and systems from hackers has forever been a serious concern. Usage of Blockchain for improved security by victimization device-to-device encryption to secure communication, key management techniques, and authentication is a potential use case to keep up cybersecuritywithintheIoTsystem.

V. WORKFLOW OF THE SYSTEM

For better understanding of the working of this proposed system, we can divide the whole procedure in two parts- firstly, the working of blockchain technology andsecondly,howthecybersecuritysystemworks.

So, in the first section weare going to discuss about the process of the blockchain technology. Blockchain is system of recording information in a way that makes it difficult or impossible to change, hack or cheat the system. A blockchain is basically a digital ledger of transactionsthat’sduplicatedanddistributedacross the complete network of computer systems on the blockchain.Eachblockinthechaincontainsanumberof transactions,andeverytimeanewtransactionoccurson the blockchain, a record of that transaction is added to every user’s ledger. The decentralized information managed by multiple users is known as Distributed Ledger Technology. Now, within the second part we are goingtodiscussregardingthecybersecurityandtheway it works. It’s sub-categorized in 3 points- analysis, implementation and support.

Analysis- It includes an intensive analysis of infrastructure, necessities and effective cyber threat scenario. Solid reasons for and against solutions. Joint realization of proof of construct, trial and take a look at surroundings

Implementation- Licensing support, consulting and deployments with the expertise from thousands of difficult IT security projects. Know how across industriesandcompanysizesandahighlevelofroutine.

Support- Troubleshooting, support and 24/7 instant facilitate with qualified contact persons. Certified power concerning product moreover as data concerning individual- environments. Enhancements, reviews and potentialanalyses.
