What is a use case in cybersecurity, and how does it work?
Blockchain technology is a distributed and decentralized ledger system that allows numerous computers to record transactions. Blockchain began as the technology that underpins bitcoin, but it has now evolved into a viable cybersecurity mitigation technology that can protect IoT device’s crypto-based network security.
Human error, in particular, continues to be the most significant source of data breaches. Blockchain completely automates data storage, removing the human element from these systems.
Blockchain cybersecurity can be used in any industry or field. This is because any type of digital asset or transaction from any business can be placed into the blockchain. The other branch of DataSpace Security, known as DataSpace Academy, provides network penetration testing training.
Because of its ability to detect any wrongdoing and provide certainty in transaction integrity, the new technology is regarded as a trustworthy cybersecurity protocol.
Use cases for blockchain
Cybersecurity use cases Blockchain has evolved into one of the most failsafe systems of dealing in the digital network space, despite not being indestructible. The technology has been praised for its ability to ensure information integrity when used as intended. Many blockchain security companies can gain from it if it is properly implemented.
Blockchain can be used in various ways because it can be helpful in a variety of situations.
Here is the blockchain technology future scope
1. Using authentication to secure edge devices -
As the focus of IT changes to ostensibly “smart” edge devices with data and connectivity, security suffers. After all, while the network’s expansion is beneficial to IT efficiency, productivity, and power consumption, it poses a security risk to CISOs, CIOs, and the rest. Given that cybersecurity, blockchain technology increases authentication improves data attribution and flow. Assists record management; many people are looking for ways to protect IoT and industrial IoT (IoT) devices.
2. Increased data security and integrity
Even though cybersecurity blockchain technology was designed without particular access controls, some blockchain implementations now address data confidentiality and access control issues. This is a significant difficulty in an age when data can be easily changed or spoofed. Still, blockchain data is fully encrypted, ensuring that it is not accessible to unauthorized parties while in transit. The best network VAPT service provider also provides services in cryptography and network security.
3. Private messaging that is secure
Startups like Obsidian use blockchain to encrypt private information transferred in chats, messaging apps, and social media. Unlike WhatsApp and iMessage, which use end-to-end encryption, Obsidian’s messenger leverages blockchain to secure users’ info. The user will not need to utilize email or any other form of authentication to use the messenger. Because metadata is disseminated at random throughout a ledger, it cannot be gathered in a single location from where it may be compromised.
4. Increasing or even wholly replacing PKI
The public key cryptography that secures emails, messaging apps, websites, and other kinds of communication is known as Public Key Infrastructure (PKI). On the other hand, most solutions rely on a centralized third-party certificate authority (CA) to issue, revoke, and store key pairs, which criminals might use to breach encrypted communications and impersonate identities. Instead, putting keys on a blockchain would theoretically reduce the possibility of false key propagation and allow apps to verify the identity of the persons with whom you’re speaking. The best python training center DataSpace Academy also provides CCNA training in Kolkata.
5. A more secure DNS
The Mirai botnet demonstrated how thieves could easily compromise crucial internet infrastructure. The attackers could disable access to Twitter, Netflix, PayPal, and other services by knocking down the domain name system (DNS) service provider for most major websites. In theory, a blockchain-based alternative to storing DNS entries might increase security by removing the single point of failure.
6. DDoS attacks are less common
Gladius, a blockchain startup, says that their decentralized ledger system protects against distributed denial of service (DDoS) attacks, which is a big claim given that DDoS attacks are now exceeding 100Gbps. According to the company, decentralized solutions can protect against such attacks by “allowing you to join to protection pools near you to provide better protection and access.”
Cybersecurity use cases on the blockchain isn't a silver bullet
However, because of its technical complexity and various systems and the fact that it cannot guarantee 100 percent security, blockchain is not a panacea.
