Nowadays, organizations are highly vulnerable to cyber attacks. In this digital business environment, data playing a crucial role for almost every organization. Therefore, preventing data has become the highest priority for every organization.

As data remain vulnerable to many cyber security attacks, the use of blockchain technology has become essential to ensure data remain safe, secure, private and authentic.

Blockchain - The decentralized distributed ledger is commonly used to record transactions across multiple computers, and it maintains the data transaction records. In this decentralized system, everyone has access to the copy of actual data. Hence there is no “official” copy exists if any changes made they will be recorded automatically. Therefore, the data remains “tamper free” and “authentic”.

Blockchain technology has now emerged to be the future of cybersecurity. Since it is highly decentralized and offline, it provides better security system against hacker to hack. It also enables organizations to distribute, sharing and collaboration easily.

Now let’s take a look at how blockchain is being used among the organizations.

Multi-Factor Authentication

DDoS - Distributed Denial of Service attacks is one of the most annoying cyber attacks in this digital time. They are uncontrolled and widespread predominantly because of our current Domain Name System. As far as we hold information in one centralized location, it's simpler for hackers to hack. With the help of blockchain's decentralized structure, circulating data over hubs, frameworks, will turn out to be practically difficult to hack.

Blockchain security startup REMME - The winner of the Microsoft Blockchain Incentive award is currently averting cyber attacks on all kind of organizations. By wiping out the space for the human mistake, and the secure one-step password system generally utilized, the scope of cracking passwords becomes hard for the opportunist hackers.

REMME's vigorous solution is based on the decentralized ledger and oversees and verifies clients and devices through multi-factor validation. It takes out the odds of going after the simplest focus for cyber hackers (weak passwords). The organization is additionally working with a few Bitcoin trades to prevent phishing attacks like the Bitfinex assault that lost $60 million. They give the security of an approved stage given cryptographic standards and an easy to understand, a single tick 2FA.

Improving IoT Security

One of the main obstacles to IoT is development, the steady risk of gadget security. As indicated by Gemalto research, 96 % of organizations, 90% of users trust that their IoT gadgets aren't secure and that there must be government direction set up. Their fundamental concern, it appears, is that a hacker will take control of their gadget, or that their information will be stolen.

At the point when medical devices are tainted with Malware, and real auto producers lose control over their vehicles, the general population's worry is justifiable. The possibility of losing control of your auto or respiratory gear is indeed panic-inducing. However, here as well, blockchain is demonstrating a few exited results.

IBM is driving the charge with regards to blockchain technology. The IBM Watson IoT Platform is enabling IoT gadgets to transmit information to blockchain records. Then, this information is incorporated into shared exchanges and records that tamper-proof and approved through secure, smart contracts.

Telstra is an Australian popular telecommunication company is also utilizing blockchain technology and prevailing to protect their “smart home” IoT ecosystems. Here, people’s identity validates through biometric authentication information. And IOTA is also demonstrating they ensure for the scaling of IoT through its Tangle development.

Filling the Skill Shortage

You may think that there are many computer engineers to go around. But, incidentally, there are more skills needed concerning cybersecurity.  

Unemployment in the business floats around zero. It implies when new positions manifest, they are complicated to fill. Furthermore, with the constant difficulties of developing tech (and with them, more greater cyber threats) by 2020, Frost and Sullivan foresee no less than 1.8 million vacant positions in the cybersecurity field. Therefore interested candidates can choose and learn cyber security course as their good career opportunity.

Organizations like PolySwarm, a decentralized antivirus commercial centre, boost nerds around the globe to contribute toward battling cybercrime. Not exclusively does this allow brilliant ability to sparkle, irrespective of their area, education, or history, but it also helps recognizes cybercrime speedier.

Dwell times is one of the most severe threats today, which means speed is of the essence. With previous McAfee Antivirus CIO Mark Tonnesen as a consultant to the PolySwarm group, leaving cybercriminals speechless and forestalling assaults is turning into a reality.

Not Everyone's in Agreement

The rational discussion about blockchain and its reasonableness as an innovation rages all through the cybersecurity business too. Regardless of the developing number of use cases and assembling energy for blockchain, not everyone in agreement about its potential.

Gunner Technology CEO - Cody Swann says, "We have been immersed with demands for blockchain applications from business leaders. Shockingly, none of these items has made it past alpha on the blockchain. Why? Since in by far most of the cases, the blockchain is an internal option to more advancements."

Head of Global Cyber Defense and Security Strategy and Vice President of Worldpay, Peter Tran, is also not precisely enthused with blockchain innovation. He trusts that man-AI and ML have the great potential in battling cybercrime. And furthermore, that existing rehauling foundations may not be an economic reality.

The challenge here will be in making blockchain innovation more viable, more comfortable, and less expensive to utilize. However, it's delighting to realize that blockchain is as of now taking care of a significant number of our issues and can go up from here.
