Overview 

Blockchain network provides an extensive risk management framework system including cybersecurity framework, assured services, and reduced cyber attacks. Blockchain technology has managed to provide security, transparency, immutability, decentralization which help in keeping valuable data in place. Blockchain offers a decentralized network with cryptography and consensus algorithms that make sure to have reliable and trustworthy transactions.

As we are aware, with the rapid increase of cyberattacks over the past decade, organizations have been spending immensely on resolving the attacks and making their Network systems more secure or risk-proof. As per Infosys and industrial reports, from 2017 to 2021, various industries and organizations have planned to spend around $1 trillion to secure and protect their systems and data from cyberattacks, online threats, etc. Also, these increasing cybercrimes and attacks can not be resolved by the traditional security systems anymore. 

Due to the Coronavirus pandemic, most of the employees are working from home, and this has caused some vulnerabilities in the whole system. Therefore, organizations are investing in removing those vulnerabilities which cause cyberattacks. For resolving and minimizing the effect of cyberattacks, the Blockchain platform is preferred and adopted by a large percentage of the industries.  

Now, How blockchain meets cybersecurity? What is the role of Blockchain Cybersecurity? And pros and cons of using Blockchain Cybersecurity! Furthermore, we will be discussing these topics in detail.  

Blockchain Meeting Cybersecurity

Blockchain is the latest cybersecurity technology that is gaining popularity and recognition in the IT ecosystem. Now, blockchain cybersecurity is what every organization needs. The Distributed Ledger Technology (DLT) of Blockchain is creating a reliable and robust cybersecurity technology. It has the potential to provide authenticity to each block added to the network. Also, blockchain builds a near-impenetrable network for hackers and safeguards the data. Blockchain cybersecurity works on the fundamentals of the peer-to-peer network. Blockchain makes a robust verification system that keeps cyber threats away. 

Blockchain cryptocurrency is built on three pillars which include integrity, confidentiality, availability of the network

  • Data Integrity: A decentralized validation network of the blockchain offers data integrity for cybersecurity. With this, monitoring and detecting any changes to the stored data or in transit data can be achieved effortlessly.   
  • Availability: Blockchain platforms can be private or publicly available. Therefore in Blockchain cybersecurity offers ensured authorized access, reliable backup, fault tolerance, redundancy, and prevent data loss. 
  • Confidentiality: Blockchain does not particularly provide confidentiality. However, the system has the power to defend against authorized access. Also without the consent of the organization, no data is made public. In fact, blockchain cybersecurity makes sure to protect the data throughout and after the transaction. 

Pros and Cons of Blockchain Cybersecurity

Implementing blockchain into cybersecurity sounds fascinating but Is it really that easy and advantageous? To learn blockchain in a better way, you must be aware of the benefits and drawbacks of blockchain technology. 

Pros of Blockchain Cybersecurity

  • Blockchain hash feature makes the network secure
  • It offers near-instantaneous update
  • Maintain the privacy of the users
  • It is fixed and sealed cryptography making it more secure
  • Blockchain technology is auditable and irreversible
  • It maintains order and timestamped 
  • No or less third parties are involved

Cons of Blockchain Cybersecurity

  • Blockchain is dealing with scalability issues. 
  • Blockchain relies on private keys
  • Adaptability challenges
  • Limited storage
  • Operational cost is high
  • Blockchain literacy 

Although blockchain technology has gained huge popularity, companies still lack qualified blockchain developers, blockchain experts, and cryptography experts. Blockchain developers are required to understand the skills required to develop the blockchain. This includes the basics of blockchain, blockchain terminologies, cryptography, high-level programming languages, and development tools. All this can be achieved by pursuing Blockchain certifications

What are Blockchain Vendors? 

Particularly here we will talk about three main blockchain vendors who tend to provide the Blockchain-as-a-Service product. Regardless of the private or public, all the industries, organizations, enterprises that are willing to deploy applications, use blockchain services and develop solutions are using Blockchain vendors. 

Amazon Web Services (AWS)

AWS provides the open-source blockchain framework, which can be deployed easily for increasing cybersecurity. Here, clients can effortlessly invite other users to the private network.

Microsoft Azure 

Microsoft Azure cloud platform offers the feature of deploying the scalable blockchain network to the clients. It allows the clients to focus on developing applications and implementing great business logic. With this cloud platform, organizations can have more availability and capability for developing better blockchain solutions which result in an improvement in cybersecurity.    

IBM Blockchain

IBM Blockchain platform offers designed Hyperledger Fabric for the organizations. As Hyperledgers fabric has the feature of being modular, it offers control on cryptography, smart contracts, consensus algorithms, and identity. Also, IBM’s. BaaS can offer to operate, model, and create networks that have the best performance and security. 

Deploying options are as follows: 

  • IBM Cloud
  • On-premises cloud
  • Third-party clouds
  • Hybrid Cloud 

Role of blockchain in Cybersecurity

Blockchain is redefining Cybersecurity in a different way, here are some of the solutions that blockchain cybersecurity is providing into the ecosystem. 

  • Identity Security
  • Transaction and Communication Security 
  • Preventing data manipulations
  • Protection from compromised nodes or server failure
  • Decentralized data storage
  • Multi-signature login capabilities 
  • Domain Name System (DNS) Security 
  • Blocking various false transactions
  • Preserving data accuracy

Conclusion

Blockchain Cybersecurity offers a path towards the security of the data in a sophisticated way. Also, it keeps cybercrimes away from the system and makes it less prone to cyber-attacks. We discussed the basics of blockchain cybersecurity and how it is affecting the ecosystem of organizations. Using Distributed ledger and consensus algorithms are the major blockchain features that positively change the fundamentals of implementing cybersecurity.
