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.

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
