Local Government Challenges

In Australia, local governments are rapidly becoming one of the most exposed sectors to cyber security threats. With growing pressure from regulators and the community to enhance cyber resilience, these agencies face the burden of protecting vast amounts of sensitive data and managing critical ICT systems, such as public CCTV and Operational Technology systems like water catchment facilities.

In Australia, local governments are consistently ranked among the top sectors reporting cyber security incidents.

As councils work toward greater cyber resilience, topics such as threat detection, continuous security monitoring, Security Information and Event Management (SIEM), Security Operations Centres (SOC), and Incident Response Readiness often come into focus. Based on our experience, Australian local governments often face challenges in aligning regulatory requirements with available capabilities, evaluating market solutions, and selecting those that optimise resource engagement, provide quick value, stay within budget, and maintain uncompromised security features.

This guide is a straightforward and practical resource, offering insights from hands-on cyber defenders who have worked with numerous Australian local governments. It aims to help councils build their cyber capabilities and effectively respond to cyber incidents.

Do All Cyber Solutions Fit Local Governments?

While numerous cyber security solutions are available from global and local providers, they often fail to address the specific needs and constraints of councils. If you are responsible for IT security in a local government organisation, you are likely to encounter several key challenges when attempting to implement a solution, involving security monitoring, incident response, and SIEM and SOC capabilities:

Minimal Internal Engagement. Many SIEM and SOC solutions operate in isolation, offering little opportunity for internal teams to build knowledge and expertise. This lack of collaboration reduces the ability of government agencies to develop in-house capabilities, and does not contribute to long-term maturity, mostly relying on service provider capability.

Limited Visibility Across Complex Systems. Many solutions provide only basic coverage, failing to account for the complexities of local government organisations. As a result, legacy and non-standard systems are often left unmonitored, leading to overlooked vulnerabilities.

Low Affordability. When attempting to cover all systems—such as branch offices, cloud environments, legacy infrastructure, and custom applications—the costs can quickly become overwhelming. Many councils discover that they cannot achieve comprehensive coverage without exceeding their budget, forcing them to leave key areas unprotected, which elevates their overall risk profile.

Complex and Expanding Costs. The cost structure of many cyber security solutions can be difficult to navigate. Licensing fees often increase over time, and additional features typically come with extra costs. For many councils, this turns cyber security into a growing financial burden that’s hard to control.

Mismatch With Regulatory Expectations. Councils are under growing pressure from regulators and auditors to meet specific cyber security standards. However, many solutions define success based on their own metrics, which may not align with the regulatory requirements that local governments are obligated to meet.

Limited Incident Response. Incident response is a critical component of cyber security, yet many SIEM and SOC solutions do not include it as part of their core offering. Instead, incident response is often an expensive add-on service, leaving councils unprepared to handle security incidents effectively without additional investment.

Data Sovereignty. Many providers cannot guarantee true data sovereignty, using distributed cloud storage or engaging offshore resources.

It’s evident that government agencies must look into solutions that will cater for their specific needs and will put them on the path to significantly improve their cyber resilience. But what does it mean to be truly cyber resilient, and what does achieving it entail?

Anecdote:

A major government organisation in Australia invested in cyber security capabilities, including SIEM and SOC
services from a global vendor. Every year, a global consulting firm conducted a review, reporting incremental
improvements in their security posture. On paper, they appeared compliant and secure, satisfying their auditors with
the systems they had in place.

However, after a significant breach that led to millions of dollars in losses and weeks of disruption, an independent review exposed numerous issues with their cyber security controls. Despite their investments, the review flagged a low level of cyber resilience. Notably, their SIEM and SOC services only covered a limited number of systems, providing little visibility across their broader environment.

It became clear that their compliance-focused approach met formal auditing requirements but failed to deliver meaningful protection in practice.

Towards Stronger Cyber Resilience

Cyber resilience refers to an organisation’s ability to prepare for, withstand, recover from, and adapt to cyber attacks or
security incidents while maintaining essential operations. A cyber-resilient organisation doesn’t just defend against
threats; it ensures that even in the event of a successful attack, it can minimise disruption, protect critical data, and
resume normal operations as quickly as possible.

Faced with the same cyber security threats as large enterprises, most councils still lag significantly in security maturity. Like many commercial organisations, Australian councils must adopt a truly resilient cyber security posture, moving beyond one-size-fits-all, box-ticking solutions prevalent in the market.

Managing complex IT environments and sensitive data, councils need to take a people-first approach to building cyber resilience. This means seeking solutions that not only move them up the maturity curve but also fully engage internal resources while leveraging external expertise available in the market.

“…councils have not clearly defined the scope of their monitoring and detection activities, or the roles and responsibilities of council staff and third parties in monitoring and detecting incidents. This limits the councils' ability to demonstrate that these activities are effectively mitigating cyber security risks.”

Return on Investment in Cyber Security

Every cyber security defender knows this – you often need to experience a breach to get funding for your cyber security
program.

While this may sound anecdotal, we’ve seen it happen time and again. Not every cyber-mature organisation has been breached, but many only allocate significant funding after a significant cyber incident, when the urgency becomes undeniable. Suddenly, budgets are unlocked, and solutions are rapidly deployed. This reactive approach reveals a deeper issue: most organisations still don’t perceive cyber threats as immediate or inevitable, even though the risks are well-known.

Calculating Return on Investment (ROI) in cyber security is especially difficult because it’s not about immediate gains or cost savings. The true value lies in preventing financial losses, reputational damage, and operational downtime. So, how can you determine if your cyber security investment is adequate for the risk profile of your local government organisation? Instead of focusing on monetary figures alone, it should be measured by how much it strengthens your cyber resilience and overall readiness to prevent and respond to cyber incidents.

During a breach, councils often confront the harsh reality that their capabilities, both human and technical, restrict their ability to follow the predefined response steps. They often struggle to extract detailed insights necessary to identify the initial point of compromise or to fully understand the impact on affected systems and data. Councils find it challenging to quickly assess the extent of the damage, confirm whether the attacker has been fully contained or determine if it is safe to commence recovery.

Reflecting on your answers to the following questions can help you determine if your intended level of investment is proportional:

  • Can your IT staff monitor all critical systems continuously, ensuring they are not compromised?
  • Do you have comprehensive visibility into user activities across both cloud and on-premises environments to quickly identify and contain account takeovers, and provide assurance to the business that attackers did not spread to other user accounts?
  • In the event of a system compromise, how quickly can your team detect, investigate, and contain the threat? Can they accurately determine the root cause, scope of impact, and whether data was exfiltrated?
  • What measures do you have in place to ensure that attackers cannot leave backdoors or regain access to your systems?
  • If you were to receive an advisory from a government regulator requesting you to review all of your systems for specific events and indicators of compromise, how quickly would you be able to do it?

Lessons From the Field

Some organisations fail to implement effective cyber security before they even get started.

How does this happen? In the cyber security industry, we often see Australian government organisations that appear to have achieved a certain level of maturity through their policies, frameworks, certifications, and tools. However, when confronted with a major security incident, they still struggle to respond and recover.

Based on many years of hands-on experience with Australian councils, we humbly share these lessons from the field, drawn from managing real
incidents, breaches, and protecting councils. Here are the most common lessons we’ve learned about why organisations struggle to implement
their cyber security programs effectively:

  1. Failing to take a people-first approach
  2. Falling into the trap of ‘black box’ solutions
  3. Compromising on coverage and visibility
  4. Lacking a plan for quick value realisation
  5. Getting lost in complex pricing models

While these issues are common, they are not impossible to overcome.The rest of this section will explore each of these lessons in detail, offering practical steps to avoid common pitfalls and implement cyber security solutions that are both effective and sustainable.

 

1. People Decisions vs. Technology Decisions

What’s the best way to choose the right cyber security solution for your organisation?
Start by considering your council’s maturity and how involved you want to be in daily security operations, such as
monitoring, investigating anomalies, and incident response.

Councils often gravitate toward two extremes:

  1. Building and managing an internal capability entirely in-house, or
  2. Outsourcing everything to a service provider.

Choosing the first option can overwhelm internal teams, as they may struggle to keep up with the latest threats and updates. On the other hand, fully outsourcing risks over-dependence on external providers, limiting internal capability development.

A common pitfall is selecting a solution based on technical requirements, without prioritising the people factor. This often leads to suboptimal outcomes, such as deploying a complex in-house solution through a third party that internal teams are not equipped to adequately support, and also cannot timely respond to occurring anomalies.

The key is to find a balance by leveraging external expertise while actively engaging your team and building internal cyber security capacity.

2. Black Box vs. Open Box

To effectively detect security threats, security events from your systems must be collected and analysed in a centralised data lake repository. How you handle and access this data determines whether you follow a black box or open box approach.

A black box approach means your data is sent to your service provider, where it becomes mostly invisible to you, and you must fully rely on them to detect threats. If they miss something, you have limited options for addressing it. While this can simplify operations, it’s not always ideal—after all, no one knows your systems better than you.

On the other hand, an open box approach gives you full access to your security data, but this often means your team is responsible for managing all threat detections. For most councils, this is unsustainable—keeping up with evolving threats and responding to anomalies around the clock places an overwhelming burden on in-house IT teams.

A more effective strategy is a hybrid approach, where you leverage the expertise of service providers while maintaining full access to your security events repository. This allows you to monitor your data and stay involved when a breach or investigation occurs, combining the best of both worlds.

3. Attack Surface Coverage and Visibility

Councils manage complex ICT environments that encompass diverse systems, critical infrastructure and legacy technologies. These interconnected environments create an extensive attack surface, which refers to all potential entry points where an unauthorised user can attempt to access or extract data from a system.

A larger attack surface increases vulnerability, especially when dealing with outdated or poorly integrated systems. In this context, visibility—the ability to monitor all assets and endpoints across your environment—is crucial for identifying threats and anomalies in real-time.

We often see councils deploying solutions that provide only partial coverage, leaving critical gaps and increasing risk. Councils should not compromise on attack surface coverage and visibility. Without full visibility, security teams are blind to potential threats, making it difficult to respond swiftly and effectively. By ensuring comprehensive coverage, councils can better protect their critical infrastructure, reduce risks, and strengthen their overall cyber resilience.

4. Time to Deploy and Time to Value

Some cyber security solutions can take months to deploy, with complex integrations and configurations delaying their effectiveness. We often see councils opting to build complex SIEM environments from scratch, deploying all detections and integrations in-house, which can extend the time to value over several months or even years.

When evaluating cyber security solutions, it’s essential to consider both the time to deploy and the time to value. Not all investments in cyber security need to require large, resource-intensive efforts, and councils should prioritise solutions that deliver quick returns on their investment.

5. Predictable Commercial Outcomes

We often see councils struggling with the commercial complexities of cyber security solutions. Many vendors and providers use pricing models based on log volumes, which can be difficult to manage in practice.

Volume-based pricing often benefits vendors who sell licences according to these metrics, but it rarely works in favour of the customer. Additionally, many features come with separate licences, making it challenging to determine what’s needed and often resulting in escalating costs over time.

Councils should seek solutions with predictable costs. Ask for a free proof of value to understand exactly which features you need and avoid unexpected expenses.

Building Your Business Case

To build stronger cyber resilience, councils must design a solution that effectively integrates people, processes, and technology. Based on our experience, these are the essential factors councils should consider to maximise their ability to detect and respond to threats with greater speed, scale, and efficiency:

  • Managed SIEM: A centrally hosted, managed SIEM system that integrates with all critical security logs, providing centralised monitoring and analysis, with experts managing threat detections.
  • Open Platform: A security operations platform that allows council personnel to get full access to security event data, not just summary reports and aggregations.
  • Capability-Building Interactions: Ongoing engagement with an external expert team, allowing the internal team to build their knowledge and skills.
  • Attack Surface Monitoring: Real-time monitoring of your entire attack surface is crucial for quickly identifying and mitigating vulnerabilities.
  • Dark Web Visibility: Proactive monitoring of the dark web for mentions of your organisation, compromised credentials, or leaked data provides early warning of potential threats.
  • Threat Intelligence: Integrating threat intelligence feeds enhances your ability to identify and respond to emerging threats.
  • DFIR (Digital Forensics and Incident Response) Capability: Enables comprehensive collection of forensic data across the organisation, allowing for detailed searches for signs of compromise and large-scale investigations.
  • NDR (Network Detection and Response): Provides continuous visibility into network traffic, offering essential evidence for tracking and mitigating threats, particularly for legacy systems and critical infrastructure.
  • Multi-Cloud Visibility: As many councils utilise multiple cloud platforms, the ability to gather and analyse log data across different cloud environments is crucial.
  • Continuous Monitoring: Around-the-clock monitoring ensures your environment is constantly observed, allowing for prompt and effective responses to incidents.
  • Threat Hunting: Actively searching for hidden threats helps uncover vulnerabilities that might otherwise go unnoticed.
  • Incident Response: A well-practised, adaptable incident response process ensures quick and efficient reactions to cyber threats.

By focusing on these essential capabilities, councils can build a comprehensive and resilient cyber security strategy that not only meets compliance requirements but also provides strong, practical protection against evolving cyber threats.

Frequently Asked Questions

SIEM and SOC services help councils collect, monitor, and investigate security events across their environment so threats can be detected and responded to faster. They are core capabilities for improving cyber resilience in local government.

Councils manage sensitive data, complex ICT environments, and, in some cases, critical infrastructure. Local governments face growing pressure to improve cyber resilience, strengthen monitoring, and be better prepared to detect, respond to, and recover from cyber incidents.

 Managed SIEM means the platform is operated and supported by a specialist provider that handles monitoring, threat detection, and incident response management, reducing the need for councils to build and maintain all of that capability internally.

 Most councils are better served by a managed model because building and maintaining an internal SIEM capability requires significant expertise, resources, and ongoing detection engineering.

SIEM is the platform that centralises and correlates security data. The SOC is the operational function that monitors alerts, investigates suspicious activity, and supports incident response. Together, they form a practical cyber resilience capability.

 Councils should look for managed SIEM, open platform access, capability-building interaction, attack surface monitoring, dark web visibility, threat intelligence, DFIR, NDR, multi-cloud visibility, continuous monitoring, threat hunting, and incident response.

 Many councils operate complex environments that include cloud services, legacy systems, diverse endpoints, and critical infrastructure. Without broad coverage, security teams are left with blind spots that increase risk and delay response.

 A black box model leaves most visibility and control with the provider. An open box model gives the customer access to its security data. A hybrid approach combines provider expertise with full access to security events and dashboards.

 Councils should expect value quickly, with critical systems covered within the first few days rather than waiting months for a project to deliver practical security outcomes.

 Threat hunting is the proactive search for hidden or advanced threats that may not have triggered alerts. It is an important part of uncovering sophisticated attacks early.

 Attack surface management is the process of identifying and reducing the entry points attackers may exploit across systems, networks, and applications. It supports continuous monitoring and earlier identification of vulnerabilities.

Dark web monitoring can help identify stolen credentials and exposed council data before threat actors use them as an entry point into the environment.

NDR is important because it detects anomalies in network traffic, helps identify rogue systems and network-level attackers, and provides forensic evidence during incidents, especially in legacy and critical infrastructure environments.

 They improve detection, provide investigation context, preserve evidence, and support faster escalation and containment. Councils should also align their incident response plan with the provider’s response processes and timelines.

 Yes. Passive monitoring, segmentation, and air-gapping are important controls for OT and SCADA environments, supported by tailored monitoring and response for council critical infrastructure.

 Councils should avoid volume-based pricing and complex licensing structures that create unpredictable costs. Predictable commercial outcomes and proof of value before commitment are a better approach.

Protecting Local Government Critical Infrastructure

Many Australian councils manage ICT systems that support critical infrastructure, such as water catchment and distribution systems. Unfortunately, security controls for these environments are often minimal, leaving them vulnerable to cyber threats.

In many cases, the vulnerabilities within these systems are not well understood, and the visibility into their networks is extremely limited, making it difficult to detect and respond to potential threats.

Recognising the importance of these systems, ThreatDefence offers practical and straightforward cyber security solutions designed specifically for such environments. As part of our Security Operations services for Australian councils, we provide tailored protection to ensure the resilience and security of critical infrastructure.

ThreatDefence is entirely Australian-based, with our technology conceived, developed, and managed domestically.
