Cyber security is the practice of providing better defence to networks against online and digital attacks that have the sole purpose of changing, accessing, or destroying digital information in the first place to extort sensitive data or money. With the passage of time, our dependence on technology and data also seems to be increasing, there is a need to further strengthen security measures for transaction data and digital currencies in a secure manner. As a form of cyber-attack, Viruses, Rootkits, Trojans and many other types of malwares can be used. Phishing, DDoS (Distributed Denial of Service), MITM (Man in the Middle), Ransomware attacks and SQL Injection are a few examples of frequent cyberattacks. Today, blockchain is developing into a viable cybersecurity risk mitigation technology. In addition, you can become a better trader by using a reputable trading platform like the BitQQQ system.
Some potential blockchain utilise cases for cyber security
DNS security —
The DNS (Domain Name System), which connects domain names to their IP addresses, functions like a public directory. Over time, hackers have attempted to enter the DNS (Domain Name System) and take advantage of these links, crashing websites in the process. Due to the decentralized and immutability nature of blockchain technology, more security is being provided with DNS with which it can be stored.
Securing Data in Transmission
Protect your data in transit, and can be protected from unauthorized access through encryption. Your data won’t fall into the hands of anyone without permission if you use blockchain’s encryption feature to protect it. For example, you don’t want private email information to fall into the wrong hands when it’s being transported. Using blockchain technology to save this type of data has several advantages, including improved data integrity and a reduction in hostile attacks.
IoT security
With the ever-increasing applications of both AI and IoT, the security of systems and data theft by hackers has always been a major concern. A possible use case for maintaining cyber security in IoT systems is the use of device-to-device encryption to keep communications, and management systems completely secure, doing so increases the security for which the blockchain is used.
Mitigating DDoS Attacks:
One of the extremely common assaults nowadays is the Distributed denial of service (DDoS) attack, in which criminals attempt to interrupt service delivery by flooding the Internet with traffic. Blockchain has shown to be a successful defence against these attacks thanks to its immutability and cryptographic features.
Blockchain Applications for Cyber Security
If you want cyber security, the organization security model is assessed by the CIA Triad Model and it serves as a reference. Blockchain technology will help you ensure that all these policies are satisfied.
- Availability: Cyberattacks that aim to affect the accessibility of technology services are on the rise right now, with Distributed denial of service (DDoS) attacks being the most frequent. However, DDoS assaults are expensive in blockchain-based systems because the attacker tries to overwhelm the network with a lot of few transactions. Due to the lack of a single point of failure, IP-based DDoS assaults are less likely to interrupt business as usual when using blockchains. Data is always accessible through different nodes, allowing for constant access to entire copies of the ledger. The systems and platforms are resilient due to the distributed operation and various nodes.
- Confidentiality: This will be referenced to ensure that all those with a legitimate requirement have an approach to relevant information. Blockchain data is completely encrypted to prevent unauthorised parties from accessing it as it travels over unreliable networks. To stop assaults from within the network, safety measures like access controls should be put into place right at the application level. By employing public key infrastructure for Certified participants and encrypting their communication, blockchain can offer sophisticated security measures.
