    Enhance Cybersecurity with Blockchain

    Blockchain Cybersecurity – The increasingly complex digital world we live in makes it harder to secure our systems against cyber threats, especially as criminals are encouraged to think outside the box and research new ways to exploit vulnerabilities.

    Cyber security is one of the most pressing challenges facing businesses, governments and individuals. Blockchain provides a way to make our data more secure by removing centralized control, which can be manipulated. It also provides strong encryption and verification of data ownership and integrity. Finally, it can even eliminate the need for some passwords, which are frequently described as the weakest link in cyber security.

    The revolutionary benefits of Blockchain technology come from its decentralized architecture and contentious roots. The distributed nature of Blockchain technology ensures that transactions are verified by different computing devices across the network, making it difficult for attackers to tamper with data or steal funds. This article will cover the challenges faced by the Cybersecurity community in blending decentralized technologies such as Blockchain and suggest some solutions to these challenges.

    Mobiloitte’s Process

    Evaluation of Safety and Soundness
    Avoid compromising the ecology, as well as manipulating or tinkering with it. Find problems associated with peers being compromised or taken over, tampered blocks, and consensus manipulations, all of which can potentially upset the ecosystem.

    Audit of the Technology

    Utilizing our one-of-a-kind governance framework, analyze the technologies and procedures utilized in Blockchain systems, such as Application Platforms, Distributed Ledgers, Consensus Protocols, Smart Contracts, and Cryptography, amongst other things.
    Security Audits

    Verify that personally identifiable information (PII) and other key data conform with applicable regulations. This should include an examination of the genesis block, chain code, algorithms, membership service providers (MSP), and so on.

    API & VM Review
    Conduct analysis and evaluation of the services that host the platform, software development kits (SDKs), and application programming interfaces (APIs) that are used by apps to connect with the Blockchain ecosystem.
    Architecture of Safety
    It reduces the potential for security breaches and makes scaling the operation easier. Analyze the design and architecture of the Blockchain ecosystem to close any potential security gaps in the system.

    Implementing Blockchain for Cybersecurity

    The Chaining Method of Blockchain


    To facilitate the execution of transactions, the blocks that make up a Blockchain ledger are sorted into a specific order and then composed. A header plus a body together into what is known as a block. Each block bears a timestamp as well as the signature of the person who created it. By establishing a pointer to the block that came before it, the blocks come together to create a chain. The immutability of the most recent block is ensured by the header, which provides a cryptographic hash of the block that came before it.


    Consensus Validation Methodology


    The consensus process’s job is to determine whether or not newly added data blocks are legitimate. To determine if the newly added data block is legitimate and qualified for the shared ledger, a predetermined member of the nodes is required to reach a consensus. The consensus method provides for ongoing verification of the completeness of both the historical transactions and the most recent data blocks.

    If a hacker wanted to alter the ledger, they would have to compromise a significant portion of nodes, hence the consensus mechanism. By putting in place an adequate number of nodes and relying on network rules to reach an agreement among those nodes, the Blockchain network contributes to the prevention of attacks of this kind.

    Architecture with Distributed Components


    A distributed network is robust to operational failure since there is no central point of failure in the system. Risk is spread among a number of nodes, and the ledger can withstand an assault on any one or a small number of those nodes without being corrupted. As a result, the Blockchain network is rendered a less desirable target for ransomware assaults due to its decentralized nature. The information that is kept in a centralized location is, in contrast, more vulnerable to assaults than the information that is stored at various nodes.

    For a ransomware attack to be successful, it is necessary to compromise the majority or all of the network’s nodes. On the other hand, restoring full service once the nodes have been compromised won’t happen instantly; there may be some delay impacts on the recovery of the network.


    Encryption


    Multiple types of encryption are utilised, each at a specific degree of implementation, to offer a multi-layered defence against potential Cybersecurity risks. Asymmetric key algorithms and hash functions are examples of the types of cryptographic algorithms.

    Hashes and digital signatures, both of which are based on encryption using public and private keys, are used to encrypt the linked lists and blocks, respectively.

    Benefits of Blockchain Cybersecurity

    The following is a list of some of the aspects that make Blockchain such exciting technology and some of the ways it should be managed:

    Privacy Protection and Data Security
    With only a minimum of governing oversight, the technology enables selective access to the transactions and information in the distributed ledger. In addition, Blockchain does not provide typical data protection goals or the capacity to circumvent privacy barriers to cyber attackers. In the grand scheme of things, this makes it more difficult to access or alter information within Blockchain ecosystems.
    Administration of the Public Key Infrastructure
    A fundamental component of Blockchain security is the use of asymmetric cryptographic keys in conjunction with digital signatures. The use of the public key to implement the protocol allows node participants to have their digital identities defined. On the other hand, the private key gives one permission to carry out the operations, such as securely encrypting, signing, and confirming transactions.
    Smart contracts

    Access control, authentication, data security, and business logic validation are some of the aspects that should be verified for Blockchain components such as smart contracts, apps, APIs, digital assets, and wallets. This results in increased levels of confidence among those who participate in the permissioned chains.
