Role Purpose: The Cloud Security (Wiz Admin) is responsible for administering, operating, and optimising Aviva’s Wiz Cloud Security Posture Management (CSPM/CNAPP) platform.
The administrator will drive operational excellence, support engineering teams, integrate Wiz into enterprise tooling, and maintain policy compliance and posture improvement.
Key Responsibilities
Platform Administration & Operations
* Own day‑to‑day administration of the Wiz platform across all cloud environments.
* Maintain Wiz connectors, least‑privilege roles, integration points, and scanning configurations.
* Ensure onboarding/offboarding of cloud accounts, subscriptions, and K8s clusters.
* Monitor platform health, ingestion coverage, API integrations, and license utilisation.
* Review, tune, and maintain security policies, controls, and baselines (e.g., CIS, NIST, ISO).
* Validate and enhance attack path analysis, identity risk detection, and data exposure mapping.
* Partner with Cloud Platform teams to ensure guardrails remain aligned with Wiz detections.
* Work with DevOps/SRE teams to embed Wiz in CI/CD pipelines for IaC scanning.
* Run onboarding sessions for teams on using Wiz Issues, Projects, and Policy‑as‑Code.
* Validate false positives/negatives and fine‑tune policy gates for Terraform, ARM/Bicep, and CloudFormation.
* Support Cloud Security, SOC, and IR teams during investigations involving publicly exposed, exploitable, or high‑risk cloud assets.
* Provide expert analysis on Wiz findings and attack paths; propose remediation and compensating controls.
Integrations & Automation
* Maintain integrations with Jira/ADO, SIEM/SOAR, Slack/Teams, and CMDB/GRC.
* Automate workflows for enrichment, prioritisation, ticketing, and reporting.
* Partner with Engineering to build auto‑remediation playbooks for safe‑to‑fix classes (e.g., public S3, permissive IAM).
Governance, Reporting & Compliance
* Produce monthly security posture reports for leadership and Risk/Compliance teams.
* Track KPIs (coverage, MTTR, SLA adherence, risk trends).
* Support external and internal audit requests using Wiz’s evidence and compliance modules.
* Manage exceptions/waivers and ensure they are reviewed and retired on schedule.
Core Technical Skills Required
* Strong understanding of AWS, Azure, and GCP security controls and architecture.
* Hands‑on experience with cloud IAM, network security, logging/monitoring, and workload security.
* Familiarity with Kubernetes security and container image scanning.
* Experience operating cloud security platforms (Wiz preferred; alternatives: Prisma, Lacework, Defender for Cloud).
* Working knowledge of Infrastructure‑as‑Code (Terraform strongly preferred).
* Understanding of identity and entitlements management (CIEM).
* Ability to analyse cloud attack paths and map misconfigurations to real exploitable risk.
Nice‑to‑Have Skills
* Experience integrating security tools into CI/CD pipelines (Azure DevOps, GitHub, GitLab).
* Knowledge of SAST/DAST/Secret scanning tools.
* Exposure to SRE or Cloud Platform engineering.
