IT SECURITY OFFICER
The Senior IT Security Officer is responsible for providing cybersecurity governance, risk management, security assurance and security advisory across ICT systems, digital services, cloud platforms and infrastructure
The role works closely with system owners, application teams, infrastructure and cloud teams, cybersecurity operations, enterprise architects, project managers, vendors and management to ensure that security risks are identified early, controls are proportionate and effective, and systems are operated in accordance with applicable Government ICT&SS policies and standards, organisational requirements, contractual obligations and recognised cybersecurity good practices.
Key Responsibilities
Cybersecurity Governance and Risk Management
· Provide independent cybersecurity governance and advisory across the project and system lifecycle.
· Lead or review cybersecurity risk assessments, including threat identification, vulnerability analysis, attack-path considerations, inherent risk, residual risk, compensating controls and risk treatment plans.
· Ensure material security risks, deviations and exceptions are properly documented, justified, tracked, escalated and formally accepted by the appropriate risk owner when required.
· Monitor recurring control gaps, overdue remediation and systemic risks, and recommend programme-level corrective actions.
· Maintain clear security decision records, evidence and audit trails for governance and management assurance.
Security Architecture and Security-by-Design
· Review application, cloud, infrastructure, network, identity and integration architectures for security risks and control gaps.
· Assess trust boundaries, data flows, privileged access paths, external exposure, administrative interfaces, API integrations and dependency risks.
· Challenge security assumptions and ensure proportionate preventive, detective and recovery controls are included before production implementation.
· Advise teams on secure design patterns for authentication, authorisation, encryption, secrets, logging, segmentation, resilience and least privilege.
· Participate in architecture review boards, design reviews, go-live readiness reviews and security acceptance decisions.
Cloud, Identity and Platform Security
· Assess cloud security designs and configurations across AWS, Microsoft Azure and/or Google Cloud, including IAM, network controls, workload protection, encryption, key management, logging and monitoring.
· Review identity and access management controls including MFA, privileged access, RBAC, service accounts, workload identities, conditional access and access lifecycle management.
· Assess Zero Trust, ZTNA, remote access, endpoint security and security service integrations where applicable.
· Evaluate security implications of SaaS, managed services, containers, Kubernetes and other modern platform technologies.
Vulnerability Management, VA/PT and Security Testing
· Review vulnerability findings and determine practical risk, remediation priority and required treatment based on business context and exploitability.
· Track remediation against applicable service levels and escalate overdue or repeated high-risk findings.
· Define or review security testing requirements, including vulnerability assessment, penetration testing, application security testing, configuration review and other assurance activities.
· Review test reports, validate remediation evidence and challenge inappropriate risk acceptance or weak compensating controls.
· Support secure development practices by reviewing relevant SAST, DAST, SCA, API security and CI/CD security evidence where applicable.
Security Operations and Incident Response
· Work with SOC and security operations teams to ensure appropriate logging, telemetry, alerting, detection use cases and escalation paths exist for critical systems.
· Participate in or coordinate cybersecurity incident response, investigation, containment, eradication, recovery and lessons-learned activities as required.
· Translate incident findings and adversary techniques into preventive improvements, detection requirements and remediation actions.
· Assess emerging vulnerabilities, CVEs and threat intelligence to determine applicability and priority for systems within the assigned portfolio.
· Support cyber exercises, tabletop exercises and operational readiness testing.
Cyber Resilience and Recovery
· Review cybersecurity aspects of business continuity, disaster recovery, backup, restoration and ransomware resilience arrangements.
· Assess recovery dependencies, privileged recovery paths, backup protection, immutability and recovery test evidence.
· Participate in disaster recovery and cyber resilience exercises and ensure security lessons are tracked to closure.
Stakeholder Management, Reporting and Leadership
· Act as a trusted cybersecurity advisor to project teams, system owners, business stakeholders and senior management.
· Explain complex cybersecurity risks in clear business language and recommend practical options for decision-making.
· Prepare concise management reports covering key risks, vulnerabilities, incidents, audit findings, remediation progress and security posture.
· Mentor junior ITSOs and contribute to consistent security assessment methods, templates, playbooks and standards across the organisation.
· Escalate material risks objectively and maintain independence when reviewing solutions or risk acceptance requests.
Minimum Requirements
· Minimum 7 years of relevant IT or cybersecurity experience, with substantial experience in cybersecurity governance, risk management, security assurance, architecture, operations, cloud security, audit or security consulting.
· At least 3 years of experience independently reviewing or governing enterprise-scale systems, major ICT projects or government/public-sector environments.
· Demonstrated ability to conduct or critically review cybersecurity risk assessments and recommend proportionate technical and governance controls.
· Strong understanding of enterprise security architecture across applications, infrastructure, networks, cloud, identity and security operations.
· Experience working with technical teams, project management, auditors, vendors and senior stakeholders.
· Strong written and verbal communication skills, including the ability to produce clear risk statements, security recommendations, management papers and audit responses.
· Ability to work independently, exercise professional judgement and escalate material risk where necessary.
· Relevant degree in Cybersecurity, Information Systems, Computer Science, Engineering or a related discipline; equivalent professional experience may be considered.
