The application technology of blockchain scenarios can be said to promote the reform of information security technology. Data changes and states that occur within a specified time are recorded through blocks, and this record book only allows additions, deletions and changes are not allowed, so the block The application of chain scenarios to network security can effectively defend against the three major security threats of man-in-the-middle attack, data tampering, and DDoS. Let's take a look at why network security can use professional blockchain scenarios.
From improving data integrity and digital identities to securing IoT devices to prevent DDoS attacks, blockchain has great potential for applications. In fact, blockchain can make a difference in all three aspects of confidentiality, integrity and availability, improving system resilience, improving encryption, auditing, and increasing transparency.
Blockchain plugs the loopholes we have left with poor security implementations and a lack of trustworthiness. In 2018, we must encrypt everywhere, always. At this time, we are unable to verify that emails received have been read or modified by others. We can't even verify the identity of the fortune.
Blockchain is a decentralized, distributed electronic ledger built on a model that provides absolute security and trust. Transactions are recorded chronologically and publicly using cryptography, with each block time stamped and linked to the previous. Importantly, these digital "blocks" can only be updated by consensus of all participants, making data interception, modification, and deletion nearly impossible.
As a result, since Gartner added it to the emerging technology “peak of the hype cycle” in 2016, blockchain has become the focus of some industry leaders, particularly in financial services, energy and manufacturing. Bitcoin payments have been the most used use case, but the technology can also be extended to applications such as content delivery networks and smart grid systems.
Securing Edge Devices with Authentication: Now that the attention of the entire IT community has begun to shift to IoT & smart devices, security is definitely one of the top considerations. While IoT can improve our work and productivity, it also means we need to face more security risks. As a result, many are looking to leverage blockchain to secure (industrial) IoT devices and improve the security of existing devices for verification, data flow and record management.
Data integrity protection: Blockchain scenarios can replace key-based data authentication techniques and use hashing algorithms to verify other copies and compare the results with the data stored on the blockchain. This way any data tampering will be discovered quickly and the data is better protected because the original hash table is stored in millions of nodes.
Protecting private information: Startups like Obsidian are using blockchain to protect private communication data in social media chat software. Unlike the end-to-end encryption used by WhatsApp or iMessage, Obsidian's chat software uses blockchain technology to protect the user's metadata. Users do not need to use email or other authentication methods to use the chat software, while the metadata is Randomly published in the "blockchain ledger", so attackers cannot collect all the user's data by compromising a single node.
Preventing hacker attacks: After entering the TB era, DDoS is still the easiest weapon for hackers to attack large targets at low cost, and DNS service is the primary target for hackers to carry out large-scale damage, but blockchain scenario technology can fundamentally solve this problem. Because blockchains use distributed storage, hackers can lose focus.
The blockchain fundamentally solves the security risks by addressing the weakest link of the platform - the influence of human factors. Blockchain technology provides end-to-end privacy and encryption while ensuring ease of use for users by using distributed ledgers and eliminating the risk of single points of failure.
Blockchain technology will continue to develop. Even the U.S. Pentagon believes that blockchain technology can serve as a cybersecurity barrier. It may help us protect individuals, companies, and governments. Bitcoin and its underlying technology, the blockchain, have now been proven to be resilient, and a host of new blockchain technologies that contribute to the development of scalability and stability, especially in the area of security, offer more hope.
