- Mastering Australian Government Security Frameworks: PSPF, ISM, and Essential Eight
Federal Government cyber security hinges on three core frameworks: the Protective Security Policy Framework (PSPF), the Information Security Manual (ISM), and the Essential Eight mitigation strategies. A Lead Cyber Advisor must not only understand these frameworks but also know how to apply them in real-world scenarios.
Step‑by‑step guide to framework implementation:
- PSPF Compliance Mapping: The PSPF provides the overarching policy requirements for government security. Start by mapping your organisation’s current security controls against the PSPF’s core principles—governance, personnel security, physical security, and information security. Identify gaps and develop a remediation plan with clear timelines.
-
ISM Control Application: The ISM offers detailed technical guidance. For each system, conduct a control-by-control assessment against the ISM’s security guidelines. This includes evaluating encryption standards, access control mechanisms, logging and monitoring capabilities, and incident response procedures.
-
Essential Eight Maturity Assessment: The Essential Eight provides a baseline for mitigating cyber intrusions. Assess your organisation’s maturity level (from 0 to 3) for each of the eight strategies:
– Application control
– Patch applications
– Configure Microsoft Office macro settings
– User application hardening
– Restrict administrative privileges
– Patch operating systems
– Multi-factor authentication
– Regular backups
Document findings with evidence and recommend specific actions to achieve the next maturity level.
- Documentation Development: Create and maintain System Security Plans (SSPs) and SSP Annexes (SSP-A) that clearly demonstrate how each control is implemented, tested, and monitored.
Command to Check System Hardening Against Essential Eight (Linux):
Check for installed patches
apt list --upgradable Debian/Ubuntu
yum check-update RHEL/CentOS
Verify application control (AppArmor/SELinux status)
sudo aa-status AppArmor
sudo sestatus SELinux
Check for unnecessary services
systemctl list-units --type=service --state=running
Audit user privileges
sudo awk -F: '($3 == 0) {print}' /etc/passwd List root-equivalent users

- Conducting Security Risk Assessments Across Cloud, Legacy, and AI Environments
Modern government ICT environments are a complex tapestry of Azure cloud services, legacy on-premises systems, and emerging AI technologies. The Lead Cyber Advisor must assess risks across this entire spectrum.
Step‑by‑step guide to multi-environment risk assessment:
- Cloud Risk Assessment (Azure): Evaluate Azure configurations against the ISM’s cloud security guidelines. Key areas include:
– Identity and access management (Entra ID configuration, conditional access policies)
– Data encryption at rest and in transit
– Network security (NSG rules, Azure Firewall, DDoS protection)
– Logging and monitoring (Azure Sentinel, diagnostic settings)
– Compliance with government data sovereignty requirements
- Legacy System Assessment: For legacy ICT systems, focus on:
– End-of-life software and unsupported operating systems
– Hard-coded credentials and weak authentication mechanisms
– Lack of encryption for sensitive data
– Absence of modern logging and monitoring capabilities
– Dependency on outdated protocols (e.g., SMBv1, TLS 1.0)
- AI Technology Assessment: As AI technologies are adopted, assess:
– Data poisoning risks in training datasets
– Model inversion and membership inference attacks
– Lack of explainability and auditability
– Compliance with privacy and data protection regulations
– Supply chain risks in third-party AI models
- Documentation and Reporting: For each assessment, produce detailed findings with risk ratings (using the ISM’s qualitative risk matrix), recommended mitigations, and prioritised action plans.
Azure CLI Commands for Security Assessment:
List all Azure resources with their security configurations
az resource list --query "[].{name:name, type:type, location:location}" -o table
Check network security group rules
az network nsg list --query "[].{name:name, rules:securityRules}" -o json
Assess Entra ID conditional access policies
az rest --method get --url "https://graph.microsoft.com/v1.0/identity/conditionalAccess/policies"
Check storage account encryption settings
az storage account list --query "[].{name:name, encryption:encryption}" -o table
Linux Command for Legacy System Assessment:
Check for outdated SSL/TLS versions openssl s_client -connect target.gov.au:443 -tls1_2 openssl s_client -connect target.gov.au:443 -tls1_1 Should fail if secure Scan for SMBv1 (vulnerable) nmap -p 445 --script smb-protocols 192.168.1.100 Check for default credentials (example) hydra -l admin -P /usr/share/wordlists/rockyou.txt ssh://192.168.1.100
- Security Documentation: System Security Plans (SSPs) and SSP Annexes
The creation and maintenance of SSPs and SSP‑As is a cornerstone of the Lead Cyber Advisor’s role. These documents provide the evidence base for system authorisation and ongoing compliance.
Step‑by‑step guide to SSP development:
- System Description: Document the system’s purpose, architecture, data flows, and interconnections with other systems. Include network diagrams, data classification labels, and a list of all hardware and software components.
-
Control Implementation Details: For each ISM control, describe how it is implemented within the system. Provide specific references to configurations, policies, and procedures. Include screenshots or command outputs as evidence.
-
Risk Assessment Summary: Summarise the findings of the security risk assessment, including identified vulnerabilities, threat sources, likelihood and impact ratings, and planned mitigation actions.
-
Continuous Monitoring Plan: Outline how the system will be monitored for ongoing compliance, including regular vulnerability scans, penetration testing, and configuration reviews.
-
SSP Annexes: Develop supplementary annexes for specific areas such as:
– SSP‑A (Cloud): Detailed cloud-specific controls and configurations
– SSP‑A (Network): Network segmentation, firewall rules, and monitoring
– SSP‑A (Personnel): Security clearance requirements and training
5. Cloud Security Hardening for Government Environments

Azure CLI Hardening Commands:
Enable MFA for all users (requires Graph API)
az rest --method patch --url "https://graph.microsoft.com/v1.0/policies/authenticationMethodsPolicy" --body '{"authenticationMethodConfigurations":[{"id":"microsoftAuthenticator","state":"enabled"}]}'
Create a network security group with restrictive rules
az network nsg create --1ame "WebNSG" --resource-group "MyRG" --location "australiaeast"
az network nsg rule create --1ame "AllowHTTPS" --1sg-1ame "WebNSG" --priority 100 --direction Inbound --access Allow --protocol Tcp --destination-port-ranges 443 --source-address-prefixes ""
Enable encryption for a storage account
az storage account update --1ame "mystorageaccount" --resource-group "MyRG" --encryption-services blob
Configure diagnostic settings
az monitor diagnostic-settings create --1ame "myDiagnostic" --resource "/subscriptions/.../resourceGroups/MyRG/providers/Microsoft.Storage/storageAccounts/mystorageaccount" --logs "[{\"category\":\"StorageRead\",\"enabled\":true}]"
6. Vulnerability Exploitation and Mitigation: Practical Defence Strategies
Understanding how attackers exploit vulnerabilities is essential for effective mitigation. The Lead Cyber Advisor must be able to guide technical teams in both offensive and defensive security practices.
Step‑by‑step guide to vulnerability management:
- Vulnerability Scanning: Use tools like Nessus, OpenVAS, or Qualys to conduct regular scans of all systems. Prioritise findings based on CVSS scores and business impact.
-
Penetration Testing: Conduct or oversee periodic penetration tests to validate security controls and identify exploitable weaknesses. Engage accredited testers (e.g., CREST-certified) for government environments.
-
Exploitation Analysis: For critical vulnerabilities, understand the exploitation vectors. For example:
– Log4Shell (CVE-2021-44228): Remote code execution via JNDI injection. Mitigation: patch, set log4j2.formatMsgNoLookups=true, or remove JndiLookup class.
– ProxyShell (Microsoft Exchange): Multiple vulnerabilities allowing remote code execution. Mitigation: apply cumulative updates and restrict access to Exchange servers.
- Mitigation Implementation: For each identified vulnerability, implement appropriate mitigations:
– Apply security patches promptly
– Implement compensating controls (e.g., WAF rules, network segmentation)
– Disable unnecessary services and protocols
– Enhance monitoring for exploitation attempts
Linux Commands for Vulnerability Mitigation:
Apply system updates sudo apt update && sudo apt upgrade -y Debian/Ubuntu sudo yum update -y RHEL/CentOS Disable unnecessary services sudo systemctl disable --1ow telnet.socket sudo systemctl disable --1ow rlogin.socket Configure firewall (UFW) sudo ufw default deny incoming sudo ufw default allow outgoing sudo ufw allow 443/tcp sudo ufw enable Set secure permissions on sensitive files sudo chmod 600 /etc/shadow sudo chmod 644 /etc/passwd

What Undercode Say
- Key Takeaway 1: The Lead Cyber Advisor role is a strategic leadership position that demands a unique blend of technical expertise, framework knowledge, and communication skills. Success requires deep understanding of PSPF, ISM, and Essential Eight, combined with the ability to influence senior decision-makers.
-
Key Takeaway 2: Security risk assessment must span the entire technology stack—from legacy on-premises systems to Azure cloud services and emerging AI technologies. A one-size-fits-all approach is insufficient; advisors must tailor assessments to each environment’s unique risks and compliance requirements.
Analysis: The Federal Government’s cyber security posture is at a critical inflection point. The convergence of cloud adoption, AI integration, and persistent state-sponsored threats demands a new breed of cyber leader—one who can operate at the intersection of technology, policy, and strategy. The Lead Cyber Advisor role exemplifies this shift, moving beyond traditional security management to become a trusted strategic partner. Professionals aspiring to this role must invest in continuous learning across multiple domains: cloud security (particularly Azure), AI risk assessment, and government-specific frameworks. The emphasis on system authorisation and SSP documentation highlights the importance of governance and compliance, not just technical controls. Furthermore, the requirement for NV1 clearance underscores the sensitive nature of the work and the trust placed in these advisors. As government agencies increasingly adopt “secure by design” principles, the demand for skilled cyber advisors who can guide secure system development from conception to operation will only grow. The ability to communicate complex risks to non-technical stakeholders is equally critical—a lesson that many technically brilliant professionals learn the hard way. Finally, the role’s focus on continuous monitoring and improvement reflects the reality that cyber security is not a one-time achievement but an ongoing process of adaptation and resilience.
