The rapid rise of connectivity has created new business opportunities, revenue streams and data rich information. It has simultaneously created threats. Expanding system attack surface vectors not previously considered or prepared for by organisations.

Malware, hacks, distributed denial of service attacks and State based threats have risen rapidly as has the capability of those perpetrating these system attacks.

The promise of Blockchain? Assistance with the creation, storage and the permissioned dissemination of immutable data. The ability to authorise, track and trace data. A better system for Digital ID, multi factor authentication and shared, congruent ledgers. The development of consensus mechanisms that pre-emptively better identify data tampering or access intrusions.

Emergent technology that overlays existing network cyber security control frameworks, best practice and procedures. Eliminating single points of failure and centralised network deficiencies.
