How should your organisation maintain resilience to cyber threats
Organisations must maintain a posture of continuous resilience to prepare for and adapt to the changing cyber threat landscape - are you prepared?
APRA has released the updated Prudential Practice Guide CPG 234 Information Security ( CPG) to assist organisations to comply with Prudential Standard CPS 234 Information Security ( CPS 234) which commenced on 1 July 2019. CPG provides insights into how APRA views cybersecurity threats and how the regulator will likely enforce obligations under CPS 234 for regulated entities.
It is evident that the threat landscape has changed considerably and could significantly impact financial institutions an APRA Executive Board Member Geoff Summerhayes has stated:
“Cyber-adversaries are targeting Australia's banks, insurers and superannuation licensees with growing frequency and sophistication. ..It is only a matter of time until an Australian financial institution suffers a material information security breach of the kind we've seen overseas, so they must be prepared.” 1
CPS 234 does not restrict the delegation of information security roles and responsibilities, however, the board has ultimate responsibility. In recognition of this, it is likely that should board members not actively question management to ensure compliance to the standards they will be held accountable, leading to potential implications for their insurance such as Directors & Officers insurance policies.
Management should work closely with their risk and compliance functions to ensure policies and reporting processes are established and that they align with the requirements of CPS 234. Regulated entities that typically rely heavily on external providers for services will need to ensure current and future third party arrangements meet the requirements of CPS 234.
Once aligned to CPS 234, all internal governance functions, in conjunction with legal and procurement, will need to ensure controls are tested regularly. This testing should extend to cover security due diligence and audits of third parties prior to contracting. Any issues highlighted by this audit process should be rectified as soon as practical to maintain compliance with the CPS 234.
Under the CPG obligations, all information held by the organisation including software, hardware or data (both tangible and intangible) will be subject to the CPS 234 and CPG 234. Given this, organisations should consider having a comprehensive data classification policy in place, to ensure they have a full understanding of their information assets.
There are strict reporting requirements and APRA will need to be notified as soon as practical but no later than 72hrs after becoming aware of a material incident. In the event, the organisation notices security control weakness then the organisation must notify APRA within 10 business days. It is important for organisations to note these requirements are in addition to any other notification requirement such as the notifiable data breach scheme or GDPR.
In order for your organisation to be prepared for and adapt to the changing threat landscape, and critically, to recover from disruptive attacks, consideration should be given to the following:
- Do you know what cyber security risks your organisation is exposed to? – determine strengths and weakness within existing controls to determine whether they are appropriate to protect, recover and respond to relevant threats.
- Have you classified your data? – not only should your organisation understand all information assets, but the information classifications should be reviewed at least annually.
- Continually update and test incident response and disaster recovery plans –ensure that the procedures in place are updated with all requirements to notify an incident, and regularly test these procedures to ensure they work practically.
- Staff awareness training – given many incidents are occurring as a result of human error it is important that your organisation conducts regular training for staff on cyber security and implement training as part of the on boarding process2.
