• Consistency provides customers and stakeholders with confidence in how you manage information security risk

• Consistency in practices mitigates the risk that breaches will occur

• Consistency in dealing with breaches minimises the financial and reputational damage

Importance of Governance - Specifically IT

Governance

• Governance – the systems by which organisations are directed and controlled

• Board responsibility – sometimes delegate to committees

• Management execute, action and report

• Well governed organisations aim to achieve strategic objectives while operating with honesty, integrity and other key principles of good governance.

• Tone at the Top!

• Policies are important – often only become a top line agenda item when something goes wrong!

• Implemented through clear and consistent standards and procedures

• More than just IT - Most breaches are caused by human error!
