Blockchain & Cybersecurity

Cybersecurity professionals should see themselves as the Guardians of the World’s Data and infrastructures

Blockchain & Cybersecurity

As a technology built primarily with security in mind, blockchain offers a lot of promise in terms of its cybersecurity potential

Blockchain & Cybersecurity

Proving that someone is who they purport to be on the web is not easy, and determined attackers are extremely adept at spoofing, phishing and mimicking their quarry.

Blockchain & Cybersecurity

It's all about Critical DATA and fight to own the

1s and 0s.

Blockchain & Cybersecurity

Data exists to be shared among counterparties, partners, clients, customers, and colleagues. Ensuring that data is only accessible to authorized eyes is a complex task. 

The Blockchain Technology

TYPICAL DATA STATES

The Blockchain Technology

DATA PROPERTIES

Data Should Have Integrity

Data Should Have Confidentiality

Data Should be Accessible

Data Should have Authenticity

Non- repudiation

TYPES OF BLOCKCHAIN

 

A true Blockchain has to be Decentralized & Distributed.

HASH FUNCTION

Core

The Blockchain Technology

HASHING VS ENCRYPTION

Core Security 

Hashing is used to validate the integrity of the content by detecting all modifications and thereafter changes to a hash output. Encryption encodes data for the primary purpose of maintaining data confidentiality and security. It requires a private key to reverse encrypted text to plain text.

The Blockchain Technology

  • DATA LAYER : Blocks

COMPONENTS

Blocks are time-Stamped

Nonce

Previous block transactions

Merkle Root Transactions

(Merkle Tree is used to cheaply prove the existence of a piece of data without validating the entire data set)

The Blockchain Technology

COMBATING DDoS

The Blockchain Technology

COMBATING DDoS

A DDoS (distributed denial of service) attack occurs when many devices connected to the Internet are recruited (as part of a ‘botnet’) to ‘attack’ i.e. simultaneously and repeatedly send traffic to a victim’s server with the aim to overload it.

The Blockchain Technology

COMBATING DDoS

The average financial cost of a DDoS attack for a small or midsize business is about $123,000

The Blockchain Technology

COMBATING DDoS

DECENTRALIZATION OF CLOUD SERVICES

Maidsafe, Blockstack

The Blockchain Technology

DECENTRALIZATION 

The Blockchain Technology

DECENTRALIZED NAME SERVERS 

Blockchain-based DNS is not vaporware

Blockstack,  Ethereum Name Service, and Namecoin.

Early Disruptors

BLOCKCHAIN IS NOT THE SILVER BULLET FOR EVERYTHING!
