Cryptography and cyber Security are embedded in the material of blocking technology. One of the major breakthroughs of Blockchain technology is the way information is secured, verified, accessible and transmitted. It differs from current systems that preserve data in one place. Blockchain distributes data across multiple nodes and is encrypted with cryptography. Although cryptocurrency exchanges are vulnerable to attack, there are virtually no instances where a large blocket has been hacked. This is one of the reasons why the rise of decentralized exchanges is essential for the security of digital assets that will later facilitate the mainstream adoption of this new class of digital assets.

For more about decentralized exchanges, I refer to "Is decentralized exchange critical to the future of digital assets?" And "about weakness, liquidity and the importance of decentralized exchanges". The use and importance of blockchain is far more critical than the transfer and exchange of digital money (cryptocurrencies).

One of the critical areas of blockchain is expected to significantly improve cyber security. For example, take a recent Facebook attack where 50 million user accounts were affected by a security breach. This is, of course, in addition to the previous vulnerabilities in Facebook privacy practices that allowed the exploitation of private user data used for political gains. As known in the Cambridge Analytica scandal (for more about Facebook's latest issues, refer to "Facebook's latest scandal reveals some concern security deficits")

The China Chip Breach

No matter how many companies spend on cyber security, as long as they keep data in central Servers, hackers will continue and cybercriminals will still find ways to exploit vulnerabilities in the centralized systems. The recent and biggest supply chain attack conducted by China against the US is still an example. A very small chip was used to infiltrate US companies like Amazon and Apple.

The small slice is allegedly planted by Chinese operations on motherboards of many servers across several companies. It was later found by a third party security company in Canada hired by Amazon, that the chip is not much larger than a row kernel. The chip was nested on Elemental's servers, which is a company acquired by Amazon. Elementary Uses Micro Computer Inc. motherboards (known as SuperMicro) to build their servers. The servers broken by this small disk can also be found in the Department of Defense datacenters, the CIA's drone operations, and the onboard naval networks. Elemental is just one of the many Supermicro customers.

The investigation, led by the American intelligence community, revealed later that the chips allowed attackers to create a "hardware" backdoor. Also, the slides seem to be inserted by Chinese operatives at factories managed by subcontractors in China. This attack is special in the sense that it exploited the hardware that differs from the software-only attacks the world is used to. It is by far regarded as the most important supply chain attack known to American companies.

The implanted microchip manipulates the instructions sent by the user instructions that call the data as it moves through the motherboard. It essentially achieves the purpose of forcing the server to communicate with contradictory computers. In addition, it can manipulate the CPU commands to prevent authentication by using the password that the server requires to access. Encryption keys that can be used on other servers but stored on the broken server can be stolen by transferring the keys to the anonymous computer with which the chip allowed the server to communicate.

Provides secret and property information from US companies, and governments have long-lasting and devastating consequences. Essentially, what is called a frog leap in the progress of opponent technology. Steal intellectual property costs hundreds of billions of dollars annually. The hacks usually come through social engineering techniques on a particular person by using their personal information by using social media, phishing, extortion or bribery.

Cyber ​​attackers usually use similar methods and techniques. This all comes down to the breaking of a single point of failure in a company or organization's cyber insurance protocol. One which can be described as a central server that contains sensitive information. Blockchain is a single failure-tolerant technology, and if it can be properly facilitated to protect sensitive information, it can be a significant challenge for cybercriminals. Blockchain essentially distributes the information on various decentralized servers. In addition, the information is encrypted using cryptography, which in turn is difficult to break. If a server is attacked, the nature of the information contained in it will be part of a chain of decentralized nodes, unknown and useless for the attacker.

The case for Blockchain Tech in Cybersecurity

Blockchain technology can also facilitate secure access authentication, especially for individuals with access to sensitive data. Make a simple example of how to obtain a digital asset class like Bitcoin using an offline hardware purse. The ownership key of the bitcoin (private key) is created and stored in isolation offline. Private keys are used to prove and verify ownership of the decentralized asset in the block chain.

A similar approach can be used to use a decentralized SSL certificate in the blockchain and use a similar private key verification mechanism to allow access to certain information so that The SSL certificate is not vulnerable to a single point of failure (ie, centralized servers). The authentication of the SSL certificate has been saved offline, which is from the Internet.

Our nearer world, where the connectivity of the Internet and the amount of data transmitted are becoming much more complex and critical than ever before, from machine learning technologies to the Internet of things, great data and artificial intelligence. All these technologies will facilitate the ease of breaking and stealing sensitive and classified information if central servers remain the dominant method of storing data. This can cause significant damage to the economy, and probably endanger national security. It is more important than ever that companies and governments begin to facilitate the use of blockchain to improve cyber security and defend companies' intellectual property and the government's sensitive and classified information.
