Blockchain technology enables multiple parties to reach an agreement on the authenticity of a transaction in a decentralized manner. These outcomes are then permanently recorded across a shared database known as a blockchain, which is cryptographically secured.
Because the blockchain ledger is shared among all participants involved, no one has sole ownership over the information that is recorded on the blockchain. This makes sure that the information cannot be tampered with. Multiple blockchain configurations are in use today that utilize different methods of reaching an agreement or consensus, depending on the type of blockchain network. For example, today’s well-known bitcoin blockchain operates as a permissionless network in which anyone can participate. Alternatively, many enterprises are choosing to operate a permissioned blockchain in which only known entities may participate as this model provides more privacy, speed, and administrative tools to manage the network.
By design, a blockchain business network securely shares information between different organizations by distributing ledger transactions to peer nodes located throughout the business network, including nodes physically located within a competing organization’s security environment and domain. The same blockchain security design features that enable these secure cross-organizational information transfers are also ideally suited to ensure the safe, efficient and cost-effective transfer of information across different government and military network security domains — for example between classified and unclassified military networks.
The security controls and assured sharing inherent to high assurance off-the-shelf hardware infrastructures, can provide secure, timely and consistent end-to-end sharing of information within and across disparate security domains. A blockchain-based cross-domain solution is likely to be less complex, more effective and less expensive than traditional, special-purpose cross-domain guards when mitigating the high stakes security risks of cross-domain information transfer.
The value to you
A blockchain cross-domain solution reduces frictions to your information exchange process and improves accessibility, accountability and traceability of information exchange. Specifically, it provides:
A single shared view of each asset throughout its life cycle regardless of the network domain.
In a standard cross-domain guard, there is no way to ensure the information residing on each side of the guard remains in sync over its lifecycle. The scope of the guard’s visibility and control is limited.
Auditable control and oversight of asset information throughout the life cycle.
The shared ledger provides a definitive, unalterable record of what was shared and by whom, even across network security domains. This eliminates trying to track and tie together the separate guard-only data flows.
Information sharing rather than merely moving data.
Data controls and sharing occur naturally and directly via the shared ledger as part of the normal blockchain business network. A traditional guard merely moves data.
Reduced cost with higher security.
The technology leverages commercially maintained open source blockchain rather than proprietary, one-off, special-purpose, limited market guard technologies. A larger user base translates to more demand, faster detection of shortcomings, and shorter innovation and repair cycle.
Blockchain has the potential to change the rules by automating trust, increasing transparency, and simplifying business processes. However, to unleash its full potential, it needs to be based on an established set of standards that meets the complex needs of the enterprise. In addition, today’s organizations are seeking industry specific solutions to transform their business processes and need the ability to build blockchain networks that are interoperable.
