Cyber Security is not only about protecting discrete networks and hubs in the event of a sophisticated attack but also about identifying real-time threats, interdiction, and remediation throughout the value chain. The platform has paid extraordinary attention to detail while designing its user interface. If you are interested in trading Bitcoin, you may Sign Up on a reliable trading platform.
In addition, several new developments, such as blockchain technology, will significantly change how cyber security works within businesses. Blockchain systems are architected to be fundamentally different from traditional databases in important ways that could revolutionize cyber security, potentially making it easier for enterprises to detect anomalies or protect against threats at all steps along the businesses and global trades. In addition, blockchain technology supports intelligent contracts for use cases requiring more complex computations than simple value transfer transactions.
Cyber-physical systems and consensus
NIST will be working with the private sector and other government agencies to ensure that cyber-physical systems are developed, operated, and evaluated with this in mind. Several issues will need to be addressed by industry and government as the Internet of Things grows and develops.
These include:
Real-time information exchange between physical and virtual (i.e., “virtual” automated) aspects of a cyber-physical system. Exchanging information between multiple physical systems that are not directly connected or interoperable (for example, between multiple buildings or in the event of a large-scale power outage). “Quantitative analysis of the outcome of the cyber-attack.”
It is related to what has been referred to as “attack surface reduction” and fundamentally differs from traditional computer security. For example, in a traditional computer system, a user maintaining a complex password scheme and not installing malware on their system offers protection primarily dependent upon their activities. However, these simple approaches to risk mitigation have dramatically reduced value in a system where malware can infect physical devices and virtual systems.
The threat model for cyber-physical systems covers both digital and physical domains; therefore, we must account for the actions of malicious humans and machines in our defenses. People could apply several blockchain-based technologies to cyber-physical systems and, more specifically, to supply chain value chains.
These include:
Blockchain technology offers the ability to manage disparate systems cryptographically in a secure and verifiable way. In a cyber-attack, cybercriminals could gain access to parts they would not otherwise have access to simply due to their inability to keep track of them in traditional databases due to various challenges, including inaccessible data or poor data quality.
It is not to say that blockchain technology does not have its challenges, but it offers a unique and sustainable way to address these challenges. For example, blockchain technology can help track a product’s provenance to ensure that the data cannot be tampered with while allowing auditors to verify its accuracy. A second example is that it can allow more efficient management of quality issues by allowing shippers and customs agents to keep track of products during shipping.
Enhancing Cybersecurity with blockchain:
People in a blockchain system can implement several decentralized governance models to simplify security authorization. For example, in the event of an attack, a blockchain-based system can quickly identify malicious actors through automatic identification and attribution mechanisms. In addition, how cybercriminals manipulate data behind the scenes could be deliberately manipulated using distributed denial of service attacks.
A blockchain protocol governs the use and determination of consensus rules for adding new blocks to a chain. As a result, only legitimate parties can access sensitive data and control certain aspects of business processes. For example, there are two main ways to create and manage synchronized proofs:
Proofs-of-work and proof-of-stake. Proofs-of-stake (PoS) is often compared to proof-of-work (PoW), but their approaches to consensus are significantly different. There is a possibility that the blockchain development community can develop a workshop for various types of blockchain technologies and determine how best to apply them to cybersecurity challenges.
What are the perks of integrating blockchain into cybersecurity models?
For manufacturing, agriculture, and logistics companies, blockchain’s immutable nature ensures that any change in its information can be easily traced even after a product has been made. In addition, it would allow fact-checking and confirmation of the actual product’s existence.
With the implementation of such a system, a company could confirm that an individual carrying out malicious activities was not an actual organization member. As a result, blockchain can reduce B2B transaction costs by reducing the need to trust entities or individuals with sensitive information.
Blockchain can also help to eliminate counterfeit products by identifying the most up-to-date information available on each product. Finally, blockchain has direct benefits in the cyber security environment because of its ability to track more than one party efficiently and veritably, which is not possible using traditional databases. Many of these benefits have been discussed above, but it is important to note that other emerging concepts may be able to apply blockchain technology.
