3 Ways Blockchain Is Revolutionising Cybersecurity

A  Blockchain Cybersecurity

Contributions are being made in Blockchain technology by The US Department of Homeland Security (DHS) as solutions have the potential to substantially improve different sectors of the digital world. When it comes to cybersecurity and online protection, solutions do not discriminate. In practice, Blockchain is an entirely secure database which stores and maintains an ever-expanding list of records. A record is maintained in the form of a block, which is linked to the previous block, hence making it a secure system, free from manipulation. In addition, to its inherent resistant it also validates new entries being added into the existing data fields. The implementation of Blockchain solutions makes data manipulation a near-impossible task. In this era of cyber crimes, where hackers have caused shut downs of networks, system malfunctions, data loss, and tempering, along with other malicious attacks, The technology can revolutionise the cyber security system. With the Blockchain solutions presenting an alternative approach to sharing and storing data, the practice of implementing it into businesses can potentially eliminate security threats.

Providing Data Integrity

An additional benefit of immutable ledger technology is that it ensures data integrity. It provides its users with the luxury of data transparency, enabling distribution of evidence via nodes and hence rendering manipulation attempts useless. Unlike other traditional practices, such as data signing that require constant verification of source and monitoring of data to make sure it hasn’t been tampered with, Blockchain solutions present a superior alternative. Keyless Signature Structure (KSI), is a practical implementation of the solutions. It inches closer to a digital world free from key-based data authentication, by storing hashes of original content on the Blockchain network. Apart from data transparency, it can revolutionise the cyber security system by contributing to change-auditing, and fine-grained access control.

Providing Decentralised Infrastructure

What’s more, is due to the decentralised nature of the Blockchain network, it is free from a single point of default. Potential attacks on the Domain Name Services (DNS), which can lead to catastrophic outcomes for major websites, can be avoided by simply decentralising the centralised infrastructure. A major flaw in the Domain Name Services (DNS) system, is due to its over-reliance with caching and hence subjecting it to DDoS attacks. Implementing Blockchain solutions will remove the fees linked with DNS, therefore, imposing costs on new entries & updates. An entirely transparent infrastructure will also make it virtually impossible for a single body to modify entries as per their requirements.

Providing Transparency

The decentralised nature of Blockchain reaches new extent as publishing keys can be offered on the platform, making identity verification an easy task. Public Key Infrastructure (PKI) secures many forms of communication and usually relies on services offered by a third party like Certificate Authorities (CA) for data storage, making it a potential target for hackers. The implementation of Blockchain solutions potentially removes the vulnerability of this procedure, leaving no target for hackers and malicious programs, to breach. By removing central authorities, Blockchain can be offered as a distributed ledger of domains. More recently, practices of not removing CA have surfaced which store hashes of issued and revoked certificates to provide users with a means of verification.
