How Can Cloud Storage Deal With Security Issues?
As detailed by Chris Pedigo of Lacework.com, 2019 saw some dark days for the cloud. While companies storing information in such data centers usually find that method cost-effective and efficient, the exceptions were notable, and troubling.
In April, 540 million Facebook records were exposed via Cultura Colectiva, a Mexican content provider. In May, Instagram saw 49 million records laid bare. July brought the Capital One breach, in which 80,000 bank account numbers (and 140,000 social security numbers) were exposed. And September saw the Autoclerk breach, where travel reservations were hacked, including those of military personnel involved with sensitive operations.
As a result, businesses are increasingly turning to blockchain to secure their cloud storage. An integral part of the larger trend toward Blockchain as a Service (BaaS), the distributed security makes this decentralized ledger far less vulnerable to hackers than the centralized servers preferred by most companies in the past.
The reasons have been well-documented. There are the cryptographic hashes unique to each block, which results in the chain’s immutability — i.e., none of the blocks can be modified without altering the whole chain. There is the peer-to-peer network, to which all data is distributed. Because it is not stored by any single entity but rather a node of users, the information within the chain cannot be changed by an outside actor. That ties into another security measure — the consensus protocol, under which all users need to verify a new block.
Finally, there is proof-of-work (PoW), the algorithm used to verify the transactions that lead to the creation of new blocks in the chain.
Again, such security is one of the great appeals of blockchain, and spending on the technology, which has tripled since 2017, is expected to reach $16 billion by 2023. Healthcare in particular is expected to reap the benefits of this technology, as blockchain spending in that sector is projected to reach $1.4 billion by 2024.
At present, however, healthcare lags behind financial services, manufacturing and energy and utilities in the industries that executives view as being most advanced in blockchain development, per a Business Insider survey. Forty-six percent of those polled believe that financial services have made the greatest strides in that area, compared to 12 percent for manufacturing, 12 percent for energy and utilities and 11 percent for healthcare. (Another eight percent view governmental use as being the most advanced.)
But it is expected that there will be precious few industries that won’t be impacted by this technology in the years to come. One report listed 58 possible areas in which blockchain can be applied, ranging from voting to ride-sharing to advertising.
The conclusion is a simple one: A decentralized storage system like blockchain can do for information what it has been doing for cryptocurrencies, keeping it safe and sound, and accessible only to those on the chain in question. The trend toward blockchain will only continue in the years ahead, and cut across all sectors.
