Blockchain and Cybersecurity: Beyond Cryptocurrency

Firstly, let us know about what is blockchain and cybersecurity. A computer network’s nodes share a distributed database called a blockchain. Their important role in cryptocurrency makes them well known. They maintain a decentralized and secure record of transactions. However, they are not limited to cryptocurrency uses. In addition, cryptocurrency is another form of payment that is a digital currency. It works using encryption. Next, cyber security is protection from cyber attacks. This is done by applying different processes and controls to protect system network program devices and data. Further, it has a goal to minimize risk and protect against the unauthorized misuse of systems and networks.

Blockchain in Cybersecurity Benefits

Nowadays blockchain and Cybersecurity work together to keep safe all sorts of digital assets and records. We all know that cryptocurrencies like Bitcoin use blockchain. It is also a valuable instrument for cybersecurity. As it helps cybersecurity in many different ways. For example, it uses cryptographic algorithms to guarantee data integrity.

The benefits of blockchain technology in cyber security are:

Enhanced Security – Blockchain is decentralized therefore there is no failure point and no attacks, unlike centralized traditional databases.
Data Integrity – Data distributed across multiple nodes reduces the risk of tampering. Hence, ensuring that records are accurate and consistent.
Tamper-proof Records – Records do not change once added to the blockchain. Thus, this immutability protects against data tampering and fraud.
Auditability – The record of data is permanent allowing easy auditing and verification.
Trust and Verification – The transparent nature of blockchain helps all participants in the network to verify transactions independently, building trust among parties.
Reduced Fraud – The records are pretty transparent so detecting and preventing fraudulent activities is easier.

Blockchain in Cybersecurity Applications

Blockchain and cybersecurity are two pillars of today’s tech world. They work hand in hand to secure our electronic world. In cybersecurity, we use a CIA model that acts as a reference to assess an organization’s security model and helps us ensure the satisfaction of all these policies. CIA is about confidentiality, integrity, and availability. Let’s see how blockchain and cybersecurity work together in this CIA model.

1. Confidentiality

Blockchain and cybersecurity means full encryption of data ensuring it will not be accessible by unauthorized parties while flowing through untrusted networks. Security measures such as access controls are implemented directly at the application level to prevent attacks from within the network. As a result, Blockchain provides advanced security controls by using public key infrastructure to authenticate parties and encrypt their communication. However backup storage of private keys in secondary storage increases the theft of private keys. Hence, to prevent this, key management procedures such as cryptographic algorithms based on integer factorization problems should be implemented.

2. Integrity

Organizations ensure data integrity through blockchains’ built-in characteristics of traceability and immutability. Consensus model protocols can further help organizations implement mechanisms to prevent and control ledger splitting in the event of a 51% cyber control attack. Further, in blockchain, with every new change, the system’s previous state is stored. Thus a fully traceable history is available. So, blockchain and cybersecurity smart contracts can verify and enforce rules between parties, preventing miners from mining blocks of data.

3. Availability

In recent times, cyberattacks impact technology services are on the surge with DDoSs being the most common types of attacks. However, in blockchain systems, DDoS attacks are costly as the attacker attempts to overpower the network with a great number of small transactions. In addition, blockchains have no single point of failure which decreases the chances of IP-based attacks disrupting the normal operation. Therefore, data remains available through various nodes, and copies of the ledger can be accessed at all times.

Blockchain Beyond Cryptocurrency

The word blockchain is mostly associated with Cryptocurrency. Crypto exchanges use blockchain. Bitcoin, Ethereum, and other popular cryptocurrency coins use blockchain to process and record transactions securely. Blockchain helps to ensure transparency and protect the financial information and identity of crypto buyers and sellers. However, we use Blockchain in various other aspects.

1. Supply Chain Management

Blockchain improves data security and communication, offering two key benefits to supply chain functions. Manufacturers shippers and customers have access to the most relevant information about the shipping process. Not only does this keep everyone in the loop, but it can also improve coordination between supply chain partners and reduce execution errors. Therefore, facilitating traceability across the entire supply chain.

2. Decentralized Finance

Platforms for DeFi make use of smart contracts. They are self-executing contracts that take action on their own when certain criteria are satisfied. Besides, DeFi applications, designed to work with blockchain technology, help people use their money for a variety of purposes. Purchases, loans, presents, and trade are a few examples.

3. Loyalty Rewards

Blockchain has been used by various places like Gyft and Loyal for the past few years. They reward their customers with tokens rather than gift cards. With this technology, companies can cut down on card wastage and the potential for fraud. Besides, also avoids the need for third parties to manage financial transactions.

4. Securing patient information

In our world inefficiency in hospital record-keeping and lack of security causes a lot of problems for providers and patients. Blockchain has the potential to secure patient data, track outbreaks of diseases, and create more accessible hubs of medical information. A decentralized database provides access to all data across locations, patients, and providers.

5. Weapons Tracking

Blockchain Technology can create a global database that cannot be altered once recorded to prevent the sale of illegal arms on the black market. Further, it could be used to track weapons from their manufacture to their sale. The database records every transaction and purchase.
