Understanding Blockchain Security Implications

The blockchain market is expected to grow by 68.4% over the next four years, with 86% of senior executives expecting blockchain to become a mainstream technology. While the majority of the world is settled on different cryptocurrencies; including bitcoin, etherium and the emerging non-fungal token (NFT) market - organizations have adopted behind-the-scenes blockchain technology. To do so, proper education and enforcement strategies are needed because without proper strategies for implementing construction details, organizations are opening up their businesses to security risks.

A handful of blockchain deployment models are: private (or internal), licensed / consortium and public. Although they all have some commonalities, each has its own nuances when it comes to its use and the security risks associated with it.

Private (Or Internal) Deployment

Blockchains on private networks are usually isolated but are intended to address internal operational performance issues. They offer an alternative data plane to traditional database architectures, in which intelligent contracts are presented as a stored procedure.

Private networks are faster than other deployment models - largely because the entire infrastructure is within the confines of the organization - but more importantly, the consensus model needs to confirm distrust. Not what is done through public chains. When deployed internally, processes become more efficient, so business asset protection measures are more controlled. We see this especially with an organization's internal supply chain - blockchain enables faster and more cost-effective delivery of services.

The organization controlling the blockchain may set permission requirements and enforce its own security precautions. By controlling which users can view, add, or modify data within the blockchain, private information is protected by third parties.

Alternatively, private blockchains are potentially more vulnerable to fraud, so organizations need to understand network collaboration so that any threat can be effectively addressed. If someone presents themselves with a malicious internal or cyber attack, the mitigation measures are essentially the same as any other cyber threat: threat testing, security vulnerabilities identification and threat detection. And penetration testing to plan response. Organizations that have failed to bridge the blockchain equity gap in their IT and cyber resources may not have their response playbooks meeting their needs.

Consortium, Or Permissioned, Deployment

Consortium blockchains - or licensed / federated blockchains - are controlled by a number of entities, which come with their own advantages and disadvantages from a security standpoint. Like private chains, licensed networks operate faster through the selection of a unified model that supports trusted relationships.

Consortium blockchains are relatively safer, given their limited exposure to outside actors. Therefore, organizations must account for the implications for data transformation and internal operational implications within the network. They should also pay attention to the agreed algorithm and ensure privacy concerns at the beginning of the adoption. This ensures that only people who want to see China can access it. When transaction confidentiality is required, an organization must ensure that selected technology supports that requirement. This type of precaution is important where individual privacy implications exist, such as when providers are using blockchain technology to share and store personally identifiable information (PII). Privacy teams must be committed to maintaining consistent data and understanding and addressing the implications of global privacy legislation.

Understanding how data can be manipulated is important in every blockchain — especially in consortium networks where there are multiple access points. Threat modeling is a way for security leaders to assess security concerns within blockchain deployments, as it identifies potential architectural and enforcement vulnerabilities, specifying which measures threaten the system. Can reduce Functional safety testing is just as important as traditional infrastructure and application testing. Organizations need to assess, identify and mitigate weaknesses in their deployment solutions.

Public Deployment

Anyone with an algorithm (think of it as a key) can enter and access blockchain data. They're generally completely decentralized and greater obvious.Public blockchains such as Bitcoin and Ethereum undermine a dynamic ecosystem that is gaining increasing attention. Its independence from any nation-state or organization constitutes a mechanism for economic and social innovation. These publicly distributed ledgers allow people to engage in the global ecosystem in a reliable way, taking advantage of technology that is inherently unreliable.

However, public networks come with significant security risks that businesses need to be aware of. We've already seen these threats play out with the recent breach of Sky Mavis, where hackers stole 173,600 ethereum cryptocurrency and 25 25.5 million from Ronin Network's Axie Infinity game. We will continue to see these violations in various forms, such as 51% attack roll, weak smart contracts and network congestion.

Aside from traditional infrastructure and application threats, these are just a few that organizations should consider when interacting with public blockchain networks and monitoring violations. Like other deployment models, leaders must ensure that their teams have sufficient education and intelligence in blockchain technology to assess their risk through tactics such as threat modeling and security testing.

Blockchains are an integral part of the technology landscape. It's one of the biggest technological advances of the last decade, and even the White House is committed to exploring its benefits nationally. The risks associated with implementing blockchains vary depending on the use case and the relevant deployment model, but the benefits of a blockchain far outweigh its security risks when properly managed.

Although many aspects of the construction at the top of this technology mirror the development of traditional solutions, the intricacies of using unreliable and distributed data aircraft need to be carefully considered. Technology and cybersecurity teams need to understand these architectural nuances as they appear to support and defend them. Beyond the framework of reference technology, some models also have privacy and regulatory implications. Once leaders and their teams have digested and understood the threats they need to address, they need to advance their strategies within the ecosystem and unlock the full potential of blockchains.
