RQ00816 - Security Specialist - Intermediate

This role will focus on two primary areas:

Continuous Threat Exposure Management (CTEM) : Leading the design and operationalization of a CTEM program that provides continuous visibility into the organization’s cyber exposure. This includes threat exposure analysis, attack path analysis, validation of remediation through testing, and risk-based prioritization to ensure critical issues are addressed first.. The resource will strengthen coordination between CTEM, SOC, and vulnerability management workflows, ensuring that exposure findings translate into actionable improvements in monitoring, detection, and response.

Demonstrated hands-on experience using Security Copilot and security automation agents to support CTEM execution, including AI-assisted threat analysis, correlation of exposure data, attack‑path analysis, and validation of exploitability

DevSecOps Pipeline Security & Cloud Security Posture Management: Implementing and enhancing DevSecOps practices by embedding security into the software development lifecycle (SDLC) and CI/CD pipelines. The resource will lead the integration of security testing tools (SAST, DAST, SCA, container/IaC scanning) into automated build processes, ensuring vulnerabilities are identified and addressed as early as possible (“shift-left” approach). In parallel, the role will oversee cloud security posture management (CSPM) and cloud-native application protection platform (CNAPP) operations across OH’s AWS and Azure environments, to continuously monitor and remediate cloud security risks. This involves implementing a CSPM/CNAPP solution to identify misconfigurations, insecure practices, and runtime threats, and working with cloud teams to reduce risk.

This role is explicitly hands-on and operational. It requires a strong technical background in cyber defense operations and the ability to execute and deliver tangible outcomes in the areas above. The resource will be expected to work across teams (SOC, DevOps, cloud engineering, etc.) to implement and execute, rather than only providing recommendations.

Responsibilities:

a. CTEM & Exposure Management:

• Operate and Mature Day‑to‑Day CTEM Activities: Execute continuous, day‑to‑day threat and exposure analysis as part of regular CTEM operations. This includes daily review and analysis of attack surface risk using Microsoft Defender, Tenable, Prisma Cloud, and native Azure and AWS security services, to identify vulnerabilities, misconfigurations, identity risks, and externally exposed assets requiring immediate attention.
  
  
  


• Perform day-to-day threat analysis leveraging multiple threat intelligence sources, vulnerability disclosures, emerging cyber threat trends, and security advisories to assess organizational impact and drive risk-based response and remediation activities.
  
  
  


• Risk-Based Prioritization & Remediation: Implement mechanisms to assess and score exposures based on exploitability, potential impact, and relevant threat intelligence. Develop risk-based remediation plans and work with IT and application teams to ensure that critical exposures are remediated promptly. Provide clear communication of risk rankings and recommended actions to stakeholders.
  
  
  

b. DevSecOps & Cloud Security Operations:

• DevSecOps Pipeline Integration: Collaborate with software development and DevOps teams to embed security testing into the CI/CD pipelines. Implement and tune SAST, DAST, SCA, and Infrastructure-as-Code scanning tools so that code, dependencies, and cloud templates are scanned for vulnerabilities with each build/release. Ensure that these processes are automated and produce actionable results for developers, with minimal false positives.
  
  
  


• Secure Coding & Remediation Support: Provide guidance and best practices to development teams on resolving vulnerabilities identified through pipeline scans.
  
  
  


• Cloud Security Posture Management: Take ownership of monitoring and improving the security posture of OH’s AWS and Azure environments. Regularly review cloud configurations and identify misconfigurations or compliance gaps (e.g., open storage buckets, overly permissive roles, unpatched workloads). Configure and operate a CSPM/CNAPP tool to continuously detect, categorize, and report such issues.
  
  
  


• Cloud Risk Remediation & Integration: Work with cloud engineering and operations teams to remediate identified cloud risks
  
  
  

Desired Skills:

• Experience in healthcare or public sector environments, particularly Ontario health sector
  
  
  


• Prior exposure to or participation in threat intelligence and threat hunting activities.

Produce a report of findings that details misconfigurations, compliance issues, and risk areas (e.g., unsecured interfaces, improper access settings, etc.), along with severity ratings. This will serve as a baseline for improvement.
  
  
  


• CSPM/CNAPP Implementation: Fully deploy and configure the CSPM/CNAPP platform for multi-cloud coverage. Deliver a configuration summary and operations guide for the platform, including configured policies, alert thresholds, and integration points (such as ticketing or notification systems). Ensure that the platform is set up to provide actionable alerts to the appropriate teams.
  
  
  


• Remediation Playbooks: For common or critical cloud findings (e.g., an S3 bucket made public, or unencrypted database instances), develop remediation playbooks or runbooks. These should outline the steps for remediation and include any automation scripts if available, enabling faster response when similar issues are detected in the future.
  
  
  

Additional Deliverables:

• Deliverables are not limited to the above and may evolve based on organizational priorities, emerging threats, or changes in the security environment during the engagement. The resource is expected to adapt to changing requirements and contribute broadly to overall security program maturity and operational resilience as needed.
