Back when blockchain had just become a thing, it was used to build Bitcoin as the most popular cryptocurrency in the world. However, a lot has changed since the initial efforts on building blockchain technology. Blockchain now plays an important role in cybersecurity and the prevention of advanced cyber threats. With that in mind, here are the most significant future use cases of blockchain for cybersecurity!
Blockchain Use Cases for Cybersecurity
Recent analytics have shown a variety of concerning security trends, including the fact that ransomware attacks happen every 14 seconds and that small businesses are often the primary targets for cyber-attacks. The growing demand for better cybersecurity solutions has led to the integration of blockchain into cybersecurity systems. The distributed and decentralized ledger system that forms blockchain technology has proven to be extremely useful in preventing threats and securing complex networks. Here are the four most important use cases that prove how efficient blockchain can be in this field.
#1 Securing Private Messaging
Messaging is one of the primary functionalities of each social media network. Billions of people are exchanging messages with one another on a daily basis, often not concerning themselves with the security of the content they’re sharing. Frequent attacks against major platforms such as Facebook and Twitter have led security experts to take private messaging to the next level. It is evident that blockchain technologies could prevent future cyberattacks if implemented properly to secure private messaging platforms.
#2 IoT Security
IoT devices have become a major trend throughout the last couple of years. Home devices such as routers, thermostats, and other appliances that can be connected to the internet come with significant security risks. Hackers can easily breach through home automation devices if there is no proper security system in place. This is where blockchain can come to the game to decentralize the administration of IoT devices, and thus significantly boost their security. Without a central admin or authority device, the future IoT networks will be far more secure.
#3 Protecting Data Transmission
Protecting data while in transit has been one of the greatest challenges when it comes to ensuring online security. Blockchain technologies can help prevent unauthorized access to data while it’s traveling across networks. This can be done by fully encrypting data in transmission by using blockchain’s decentralized ledger systems. Such security systems would make communications far more reliable and less susceptible to malicious attacks.
#4 Preventing DNS and DDoS Attacks
Last but not least, blockchain can be used to prevent common DNS and DDoS attacks where hackers overwhelm servers to prevent users from accessing resources, sites, or platforms. These attacks can shut down or at least slow down entire systems and cause major disruption in their operation. By using blockchain technology to decentralize DNS entries, security teams will be able to prevent these types of attacks in the future. Although no security solution is 100% efficient, blockchain implementation will significantly reduce the risk of DNS and DDoS attacks.
Conclusion
Throughout the last couple of years, we’ve learned that blockchain technology can be used for far more than just crypto values. If utilized properly, blockchain can be a powerful security tool that could protect data and devices on a corporate and even personal level. By scattering data storage, access control, and traffic across multiple locations, blockchain makes it nearly impossible for hackers to infiltrate systems or even plan to execute cyberattacks. While we can’t be certain of what the future holds, there is no doubt that blockchain will become an irreplaceable part of cybersecurity strategies.
