Cybersecurity is a familiar term. It is the practice of securing networks and systems from different digital attacks that target to destroy, change, or access digital information or to steal crucial data or money. As data and technology are becoming very important for businesses, implementing security measures has become vital like never before so that transactions and digital data are protected. Malware like Rootkits, Trojans, or viruses. Man in a Middle or MITM attack, Phishing, SQL injection, Distributed denial of service or DDoS attack, Ransomware attacks, etc.
What Is Blockchain?
Blockchain is a distributed and shared digital ledger to record transactions as blocks. It helps to transparently store information as it is immutable and easily accessible by all members.
How To Use Blockchain In Cybersecurity?
Some of the use cases of blockchain in cybersecurity are
- IoT Security
As IoT and AI are increasingly becoming popular, systems and data have to be secured from the attack of hackers. Blockchain can help to increase security through device-to-device encryption which enables protected communication, important management techniques, as well as authentication. This is one of the major uses of blockchain to ensure cybersecurity in various IoT systems.
- Authenticity Of Software Downloads
Blockchain helps to verify installers and updates to avoid the infection of malware devices on the devices. The hashes will be recorded on the blockchain and it compares new identities of software with the hashes, which verifies the authenticity of the downloads.
- Protection Of Data Transmission
Blockchain uses encryption to protect the transmitted data from any unauthorized access.
- Decentralized Storage For Important Data
Data created every day is drastically rising. Blockchain solutions can be used to get decentralized storage, which will help to provide security for critical digital information.
- Eliminate DDoS Attacks
DDoS attacks are one of the highly popular cyberattacks seen today. In this process, hackers target to create a huge flow of internet traffic. This will affect the free flow of services. Features like cryptography and immutability make blockchain an ideal solution to prevent these attacks.
- DNS Security
DNS or Domain Name System can be considered as a public directory that connects domain names with their IP addresses. Hackers have been trying their best to hack these DNS and destroy the links, causing the sites to crash. Blockchain properties like decentralized systems and immutability help to securely store DNS.
Benefits Of Blockchain Applications
Blockchain provides many benefits for blockchain applications. Blockchain data are fully encrypted, which makes it hard for unauthorized access using untrusted sites. It offers advanced security tools with the help of public key infrastructure for the authentication of parties and helps to encrypt all communications.
Traceability and immutability are built-in characteristics of blockchain technology, which help organizations to achieve data integrity. Organizations can use smart contracts to enforce and verify rules between two parties, thus avoiding miners from trying to mine data blocks. It is hard to find failure points in blockchain, which avoids the possibilities of DDoS attacks based on IP, which interrupts the common operation process.
