• Blockchain is a system of recording information in a method that makes it
difficult or impossible to change, hack, or cheat the system. A blockchain is
essentially a digital ledger of transactions that is duplicated and distributed
across the entire network of computer systems on the blockchain.
• Blockchain technology is a structure that stores transactional records, also
known as the block, of public transaction in several databases, known as the
chain, in a network connected through peer-to-peer nodes. This storage is
typically referred to as a digital ledger.

• No information system can be 100% secure. Blockchains underlying capabilities of
Confidentiality, Integrity and Availability employ cyber security controls and standards
which need to be adopted for organizations using blockchains within their technical
infrastructure.
• Organizations can adopt a holistic approach of People, Process and technology as a
triad in implementing these strategies in combating cyber attacks.
• Another approach developed by a consulting firm is the Secure, Vigilant and Resilient
(SVR) cyber approach which will support entities to remain secure and resilient to
evolving to cyber threats.
• Secure: Having risk-prioritized controls to defend emerging threats.
• Vigilant: Having threat intelligence and situational awareness to identify harmful
behaviour.
• Resilient: Having the ability to recover from and minimize the impact of cyber
incidents. 12
