Project Overview

Security architecture assessments and consultations are required as a prerequisite to the go live in order to comply with OH Policies and standards. Security architecture assessments ensure compliance of product/project architectures with approved security architectures standards and cloud decision records prior to the project go-live date.

Key Responsibilities

- Develop and maintain security reference architectures, network diagrams and other guidelines to support the policies and standards, enabling the delivery of target state enterprise-level Information Security capabilities, and reducing the risk of siloed and redundant solutions.
- Develop security requirements and advise on technologies to be used in cloud environments during an entire project lifecycle.
- Ensure optimal placement and adequacy of the technology to achieve an ideal cloud security architecture, with respect to the cloud service model being used.
- Analyze proposed solution architectures, technology, design, and IT development processes to identify potential threats and vulnerabilities, and to recommend options that enhance the security of solutions and business processes.
- Act as a subject matter expert and may take on more complex work in developing plans and deliverables and interacting with key internal partners.
- Manage multiple security related projects simultaneously, and present status updates to upper management.
- Leverage existing best practices in addition to proposing, developing, and integrating best practices as they relate to business, policy, information, security, application and technical infrastructure architecture.
- Identify and escalation issues and work with projects to ensure application management and quality standards are adhered to.
- Analyze proposed solution architectures, technology, design,



conducting an assessment to identify security architecture gaps and deviations from approved standards/patterns and to identify potential threats and vulnerabilities, then recommend options that enhance the security of solutions.
- Development, update and contribution to security architecture standards, patterns, and reference architectures for cloud environments.
