Blockchain stumbling blocks
Although the potential of this technology appears vast, many challenges have prevented broader adoption of blockchain companies’ cybersecurity systems.
“Despite the acceptance of blockchain-based solutions in several business domains, we have foreseen some critical challenges in the area of cybersecurity,” says Umashankar.
In all digital transformations, complexity remains a key issue. Integrating blockchain with established systems can be complex and resource-intensive.
And yet, because blockchain is not as widely implemented, many industry vendors are small and use blockchain to solve specific problems. Therefore, its integration into larger enterprises with large environments and network architectures proves to be a real challenge.
Even if a company wanted to take a piecemeal approach, with many vendors providing different blockchain integration elements, interoperability remains an issue.
Additionally, the wide variety of blockchain platforms can make it difficult to share information between them, leading to interoperability issues for cross-network implementations.
Scaling as the network grows can also cause congestion, leading to slower transaction processing times and higher fees. This drawback makes blockchain less viable for real-time security applications.
But one of the major problems is perhaps linked to that of decentralization: the dissemination of data. Because blockchain is decentralized, this can pose a governance challenge, particularly when a network is managed by a consortium or community outside of the organization’s control.
“When it comes to security solutions based on a public blockchain network such as a sovereign identity solution or a verifiable identity solution,” continues Umashankar, “there is still a regulatory and compliance issue regarding data Crucial PII shared in an open peer-to-peer decentralized network.
This means that while the benefits of blockchain and decentralization are very real, in practice it is not easy to implement blockchain within an organization and across all systems.
Replace or increase?
While blockchain and decentralized systems bring benefits to cybersecurity systems, they also introduce several unresolved issues.
However, for the Internet of Things (IoT), for example – a network sometimes made up of hundreds of endpoints – the applications are there.
“The IoT can benefit from a considerable boost thanks to blockchain. Devices can use blockchain to have unique identifiers and rely on lighter encryption protocols like DTLS,” explains Konstantinos. “They can be controlled over a network and such a configuration could prevent malicious devices, unauthorized access and elevated privilege levels.”
Likewise, implementing them as part of a broader cybersecurity strategy can provide some benefits while avoiding some complexities.
“Blockchain is not a panacea for security issues,” says Sami. “Organizations need to distinguish between the security features inherent in blockchain and the additional security controls that need to be implemented. »
Despite ongoing challenges, blockchain presents a solution for creating more secure, efficient, and user-centric digital identity systems.
With cybersecurity often relying on defense in depth, adding another trusted step like blockchain to other protocols, like multi-factor authentication, can bring tangible benefits to security postures. Even if it doesn’t transform him yet.
