Using Blockchain Helps Secure Data Against Attacks

Blockchain technology provides the ability to protect data from malicious attackers, preventing potential fraud and reducing the chance of data being stolen or compromised. This is due to its distributed nature. To corrupt a blockchain, every system that processes it would have to be attacked, which could be thousands of systems. It relies on strength in numbers.

Blockchain is a technology that allows individuals and companies to make instantaneous transactions on a network without any middlemen, such as banks. Transactions made on blockchain are completely secure, and, by function of blockchain technology, are kept as a record of what happened.

When Blockchain is in use, if someone tries to alter the data, the system analyses the entire chain, compares them with the data change, and then excludes any that don’t match up, thereby preventing unauthorised changes. Blockchain can be used in relation to threat and operational monitoring scenarios, such as IoT device security. Using blockchain, devices can “work together” and agree what “normal looks like” and, as a result, alert or lock devices that are behaving beyond the boundaries of normality. 

The beauty of blockchain is that there is no central authority and thousands or millions of nodes collectively control and make decisions based on the blockchain integrity.

The concept of an immutable ledger can be applied to asset management or data integrity and configuration controls, so that history of asset profiles or integrity hashes for software downloads can be stored in a blockchain. 
The hashes for a given download or software install can be compared to the hash stored in the blockchain to help ensure that software is not compromised with malware, and so on.

Blockchain’s immutability means the attacker can no longer hide their tracks or tamper with access logs to erase records of their unwarranted access.

Overall, blockchain does have a purpose in relation to maintaining record integrity that can be applied to many use cases. 
It may be a little over-hyped in terms of its applications, but it is a solid technology with strong arguments for certain applications.
