This audit assessed nine agencies’ compliance with the NSW Cyber Security Policy (CSP) including whether, during the year to 30 June 2020, the participating agencies:
Key elements to strengthen cyber security governance, controls and culture are not sufficiently robust and not consistently applied. The CSP is not achieving the objectives of improved cyber governance, controls and culture because:
In this report, we repeat recommendations made in the 2019 and 2020 Central Agencies reports, that Cyber Security NSW and NSW Government agencies need to prioritise improvements to cyber security resilience as a matter of urgency.
Cyber Security NSW should:
Agencies should resolve discrepancies between their reported level of maturity and the level they are able to support with evidence.
Separately, the agencies we audited requested that we not disclose our audit findings. We reluctantly agreed to anonymise our findings, even though they are more than 12 months old. We are of the view that transparency and accountability to the Parliament of New South Wales are part of the solution, not the problem.
The poor levels of agency cyber security maturity are a significant concern. Improvement requires leadership and resourcing.
The NSW Cyber Security Policy requires agencies to report their level of maturity implementing the mandatory requirements, which includes the ACSC's Essential 8.
This report assesses whether state government agencies are complying with the NSW Cyber Security Policy. The audit was based on the level of compliance reported at 30 June 2020.
Our audit identified non-compliance and significant weaknesses against the government’s policy.
Audited agencies have requested that we not report the findings of this audit to the Parliament of New South Wales, even though the findings are more than 12 months old, believing that the audit report would expose their weaknesses to threat actors.
I have reluctantly agreed to modify my report to anonymise agencies and their specific failings because the vulnerabilities identified have not yet been remedied. Time, leadership and prioritised action should have been sufficient for agencies to improve their cyber safeguards. I am of the view that transparency and accountability to the Parliament is part of the solution, not the problem.
The poor levels of cyber security maturity are a significant concern. Improvement requires dedicated leadership and resourcing. To comply with some elements of the government’s policy agencies will have to invest in technical uplift and some measures may take time to implement. However, other elements of the policy do not require any investment in technology. They simply require leadership and management commitment to improve cyber literacy and culture. And they require accountability and transparency. Transparent reporting of performance is a key means to improve performance.
Executive summaryCyber security is increasingly a focus of governments around Australia. The Australian Cyber Security Centre (ACSC) is the Australian Government’s lead agency for cyber security and is part of the Australian Signals Directorate, a statutory authority within the Australian Government’s Defence portfolio. The ACSC has advised that government agencies at all levels, as well as individuals and other organisations were increasingly targeted over the 2021 financial year 1 . The ACSC received over 67,500 cybercrime reports, a 13 per cent increase on the previous year. This equates to one reported cyber attack every eight minutes. They also noted that attacks by cyber criminals and state actors are becoming increasingly sophisticated and complex and that the attacks are increasingly likely to be categorised as ‘substantial’ in impact.
High profile attacks in Australia and overseas have included a sustained malware campaign targeted at the health sector 2 , a phishing campaign deploying emotet malware, spear phishing campaigns targeting people with administrator or other high-level access, and denial of service attacks. The continuing trend towards digital delivery of government services has increased the vulnerability of organisations to cyber threats.
The COVID-19 pandemic has increased these risks. It has increased Australian dependence on the internet – to work remotely, to access services and information, and to communicate and continue our daily lives. Traditional security policies within an organisation’s perimeter are harder to enforce in networks made up of home and other private networks, and assets the organisation does not manage. This has increased the cyber risks for NSW Government agencies.
In March 2020, Service NSW suffered two cyber security incidents in short succession. Technical analysis undertaken by the Department of Customer Service (DCS) concluded that these cyber breaches resulted from a phishing exercise through which external threat actors gained access to the email accounts of 47 staff members. These attacks resulted in the breach of a large amount of personal customer information contained in these email accounts. These attacks were the subject of the Auditor-General's report on Service NSW's handling of personal information tabled on 18 December 2020.
This audit also follows two significant performance audits. Managing cyber risks, tabled on 13 July 2021 found Transport for NSW and Sydney Trains were not effectively managing their cyber security risks. Integrity of data in the Births, Deaths and Marriages Register, tabled 7 April 2020 found that although there are controls in place to prevent and detect unauthorised access to, and activity in the register, there were significant gaps in these controls.
The NSW Cyber Security Policy (CSP) was issued by Cyber Security NSW, a business unit within the Department of Customer Service, and took effect from 1 February 2019. It applies to all NSW Government departments and public service agencies, including statutory authorities. Of the 104 agencies in the NSW public sector that self-assessed their maturity implementing the mandatory requirements, only five assessed their maturity at level three or above (on the five point maturity scale). This means that, according to their own self-assessments, 99 agencies practiced requirements within the framework in what the CSP’s maturity model describes as an ad hoc manner, or they did not practice the requirement at all. Cyber Security NSW and NSW Government agencies need to prioritise improvements to their cybersecurity and resilience as a matter of priority.
This audit looks specifically at the compliance of nine key agencies with the CSP. It looks at their achievement implementing the requirements of the policy, the accuracy of their self-assessments and the attestations they made as to their compliance with the CSP.
The CSP outlines the mandatory requirements to which all NSW Government departments and public service agencies must adhere. It seeks to ensure cyber security risks to agencies’ information and systems are appropriately managed. The key areas of responsibility for agencies are:
DCS has only recommended, but not mandated the CSP for state owned corporations, local councils and universities.
NSW Government agencies must include an attestation on cyber security in their annual report and provide a copy to Cyber Security NSW by 31 August each year stating whether, for the preceding financial year, the agency has:
The purpose of the attestation is to focus the agency's attention on its cyber risks and the mitigation of those risks.
Agencies assess their level of compliance in accordance with a maturity model. The CSP does not mandate a minimum maturity threshold for any requirement, including implementation of the Australian Cyber Security Centre's (ACSC) Essential 8 Strategies to Mitigate Cyber Security Incidents (Essential 8).
Agencies are required to set a target maturity level based on their risk appetite for each requirement, seek continual improvement in their maturity, and annually assess their maturity on an ascending scale of one to five for all requirements (refer to Appendix two for the maturity model). Each control within the Essential 8 is assessed on an ascending scale of zero to three reflecting the agency's level of alignment with the strategy (refer to Appendix three for the maturity model).
We assessed whether agencies had provided accurate reporting on their level of maturity implementing the requirements of the CSP in a documented way and covering all their systems.
The scope of this audit covered nine agencies (the participating agencies). These agencies were selected because they are the lead agency in their cluster, or have a significant digital presence within their respective cluster. The list of participating agencies is in section 1.2. The audit aimed to determine whether, during the year to 30th June 2020, the participating agencies:
While the audit does assess the accuracy of agency self-assessed ratings, the audit did not assess the appropriateness of the maturity ratings.
Agencies can decide not to implement requirements of the CSP, or they can decide to implement them only in an informal or ad-hoc manner. The CSP allows agencies to determine their desired level of maturity in implementing the requirements on a scale of one to five - level one being 'initial – not practiced' and level five being 'optimised'. The desired level of maturity is determined by the agency based on their own assessment of the risk of the services they provide and the information they hold.
The reporting template for the 2019 version of the CSP stated that level three maturity - where a policy requirement is practiced on a regular and consistent basis and its processes are documented - was required for compliance with the CSP. This requirement was removed in the 2020 revision of the reporting template.
This CSP does not require the decisions on risk tolerance, or the timeframes agencies have set to implement requirements to be documented or formally endorsed by the agency head. There is no requirement to report these decisions to Cyber Security NSW.
Some jurisdictions, with a similar policy framework to NSW, require agencies to demonstrate reasons for not implementing requirements, and require agency heads to formally acknowledge the residual risk. The NSW CSP does not require these considerations to be documented, nor does it require an explicit acknowledgement and acceptance of the residual risk by the agency head or Cyber Security NSW. The NSW CSP does not require that the records of how agencies considered and decided which measures to adopt to be documented and auditable, limiting transparency and accountability of decisions made.
All of the participating agencies had implemented one or more of the mandatory requirements at level one or two. Maturity below level three typically means not all elements of the requirement have been implemented, or the requirements have been implemented on an ad-hoc or inconsistent basis.
Eight of the nine agencies we audited had not implemented any of the Essential 8 strategies to level three – that is, fully aligned with the intent of the mitigation strategy. At the time of this audit the ACSC advised that:
as a baseline organisations should aim to reach to reach Maturity Level Three for each mitigation strategy 3 .
The Australian Signals Directorate 4 currently advises that, with respect to the Essential 8:
[even] level three maturity will not stop adversaries willing and able to invest enough time, money and effort to compromise a target. As such, organisations still need to consider the remainder of the mitigation strategies from the Strategies to Mitigate Cyber Security Incidents and the Australian Government Information Security Manual
All agencies failed to reach even level one maturity for at least three of the Essential 8.
The NSW maturity model used for the Essential 8 does not fully align with the ACSC’s model. At the time of this audit the major difference was the inclusion of level zero in the NSW CSP maturity scale. Level zero broadly means that the relevant cyber mitigation strategy is not implemented or is not applied consistently. Level zero had been removed by the ACSC in February 2019 and was not part of the framework at the time of this audit. It was re-introduced in July 2021 when the ACSC revised the detailed criteria for each element of the essential 8 maturity model. The indicators to reach level one on the new ACSC model are more detailed, specific and rigorous than those currently prescribed for NSW Government agencies. Cyber Security NSW asserted the level zero on the CSP maturity scale:
is not identical to the level zero of the ACSC’s previous Essential 8 maturity model, but is a NSW-specific inclusion designed to prevent agencies incorrectly assessing as level one when they have not achieved that level.
Attestations did not accurately reflect whether agencies implemented the requirements
Of the nine participating agencies, seven did not modify the proforma wording in their attestation to reflect their actual situation. Despite known gaps in their implementation of mandatory requirements, these agencies stated that they had 'managed cyber security risks in a manner consistent with the Mandatory Requirements set out in the NSW Government Cyber Security Policy'. Only two agencies modified the wording of the attestation to reflect their actual situation.
Attestations should be accurate so that agencies’ and the government’s response to the risk of cyber attack is properly informed by an understanding of the gaps in agency implementation of the policy requirements and the Essential 8. Without accurate information about these gaps, subsequent decisions as to prioritisation of effort and deployment of resources are unlikely to effectively mitigate the risks faced by NSW Government agencies.
Seven of the nine participating agencies reported levels of maturity against both the mandatory requirements and the Essential 8 that were not supported by evidence.
Each of the nine participating agencies for this audit had overstated their level of maturity against at least one of the 20 mandatory requirements. Seven agencies were not able to provide evidence to support their self-assessed ratings for the Essential 8 controls.
Where agency staff over-assess the current state of their cyber resilience, it can undermine the effectiveness of subsequent decision making by Agency Heads and those charged with governance. It means that actions taken in mitigating cyber risks are less likely to be appropriate and that gaps in implementing cyber security measures will remain, exposing them to cyber attack.
We reviewed the data 104 NSW agencies provided to Cyber Security NSW. The 104 agencies includes nine audited agencies referred to in more detail in this report. Our review of the 104 agency self-assessment returns submitted to Cyber Security NSW highlighted that, consistent with previous years, there remains reported poor levels of cyber security maturity. We reported the previous years’ self-assessments in the Central Agencies 2019 Report to Parliament and the Central Agencies 2020 Report to Parliament.
Only five out of the 104 agencies self-assessed that they had implemented all of the mandatory requirements at level three or above (against the five point scale). Fourteen agencies self-assessed that they had implemented each of the Essential 8 controls at level one maturity or higher (using Cyber NSW’s four point scale). The remainder reported at level zero for implementation of one or more of the Essential 8 controls, meaning that for the majority of agencies the cyber mitigation strategy has not been implemented, or is applied inconsistently.
Where agencies had reported in both 2019 and 2020, agencies’ self-assessments showed little improvement over the previous year’s self-assessments:
The poor levels of maturity in implementing the Essential 8 over the last couple of years is an area of significant concern that requires better leadership and resourcing to prioritise the required significant improvement in agency cyber security measures.
Cyber Security NSW should:
1. monitor and report compliance with the CSP by:
2. require agencies to report:
3. identify and challenge discrepancies between agencies' target maturity levels and the risks of the information they hold and services they provide
4. more closely align their policy with the most current version of the ACSC model.
Participating agencies should:
5. resolve the discrepancies between their reported level of maturity and the level they are able to demonstrate with evidence, and:
Repeat recommendation from the 2019 Central Agencies report and the 2020 Central Agencies report
6. Cyber Security NSW and NSW Government agencies need to prioritise improvements to their cyber security and resilience as a matter of urgency.
