Cybersecurity threats are becoming more common and intense. New threats like phishing, crypto-jacking, IoT attacks, malware, SQL injection, artificial intelligence etc have become a major issue for anyone connected to the online world.

Technological advancements have led cybercriminals to become even better at creating and exploiting breaches. As a result, there have many technologies have been created to combat these attacks. Nowadays, we can protect sensitive and personal data by creating a backup through reputable data storage and server companies. This ensures that we can recover any important document anytime a malicious data loss occurs on our end. Another promising option for improving cybersecurity has the implementation of blockchain technology.

What is Blockchain all about?
A relatively new form of technology, blockchain is gaining in popularity for its virtually unbreachable nature. The blockchains are records or information stored on chains across a distributed network that millions of people can access globally and instantly. All the data stored on the blockchain is kept secure using cryptography and users are able to add details to the blockchain. Members in the same network are responsible for verifying whether any new addition or edit is valid and genuine. This is possible due to three key systems:
1. Receivers key.
2. Public key.
3. Private key.

With the overview out of the way, let’s look at some key aspects of blockchain that can fortify and improve cybersecurity.

Prevents Data Theft and Fraud
One of the most effective tools for protecting data from fraud and theft is blockchain technology. It basically severely complicates the work of hackers. For them to corrupt and destroy a blockchain, they will need to have access to all the information stored across each user’s computer in the world. This comes to millions of computers each storing a precise copy of all or some of the data.

This ensures that it is virtually impossible for hackers to disable an entire network. Even if hackers manage to affect a couple of computers, undamaged nodes or computers on the network can still run normally to store and verify data. This means that larger blockchain networks with a high amount of users are subject to a lower risk of attack from hackers. This is due to the compounding of complexity that is required to access such networks.

Verifying the Validity of Software Updates and Downloads
Hacking tools like a trojan horse, viruses and worms which invade computers appear in different forms. As a result, it is becoming more difficult to identify for a non-expert. Nowadays, there are also many ransomware and malware that are posing as legitimate applications. This is where blockchain technology comes into effect. It assigns exclusive hashes for updates and downloads, which makes it easier to compare the has of the required download with that provided by the developer. As a result, using blockchain technology significantly lowers the chances of infecting your computer system from well-disguised viruses.

Safer Domain Name System
Hackers enjoy a lot of success with DNS (Domain Name Systems) mainly due to it being highly centralized. The combination of using DNS and DDoS(Distributed Denial of Service) attacks can leave a website unusable for prolonged periods. Blockchain-based security systems tackle this quite effectively. Due to their decentralized nature, hackers find it very difficult to identify and exploit one single point of vulnerability. This makes it possible to store domain details immutably on heavily distributed ledgers. Such immutable smart contracts also give power to the connection, giving added overall security.

Conclusion
Hacking can infiltrate and corrupt the best of systems regardless of preventive measures. Although in the world of cybersecurity, there is no foolproof method for keeping hackers at bay. Blockchain technology is a promising and effective method for preventing sensitive and important data from falling into the wrong hands.
