Enterprise Security Architecture and Framework Design Questions
Designing comprehensive security architecture and enterprise scale security frameworks for large organizations. Topics include layered security and defense in depth applied at enterprise scale, zero trust and microsegmentation strategies, identity and access management at scale, network segmentation and secure network architecture, encryption strategies for data at rest and in transit, secrets and key management, audit logging and telemetry placement, incident response integration, backup and disaster recovery planning, and platform and infrastructure hardening. Candidates should demonstrate how to align security architecture with business goals, translate an architectural vision into a prioritized roadmap and governance model, reason about scalability and interoperability, justify trade offs between security and developer velocity, and design automation and orchestration to enable secure operations at scale.

Write a tool in Python that scans a git repository history for potentially exposed secrets. The tool should identify likely credentials (for example AWS access key patterns, private key headers, common token formats), report commit hash, file path, and a snippet of the offending content, and optionally create a remediation plan with rotated credentials. Discuss false positives, negatives, and performance on large repos.

Design a backup and disaster recovery approach for encrypted customer data replicated across two regions with an RPO of 15 minutes and RTO of 2 hours. Explain how keys are managed so recovery is possible if a region is lost, how you ensure backups are immutable and tamper-evident, and how to validate restores while preserving confidentiality.

What are the primary components of an enterprise Identity and Access Management (IAM) system? Describe authentication versus authorization, role-based access control (RBAC) versus attribute-based access control (ABAC), and typical integrations such as SSO, MFA, provisioning connectors, and lifecycle automation.

From a software engineering perspective, what are the critical features and APIs a secrets management system must provide to be usable by application teams? Consider runtime secret retrieval, authentication methods, access policies, rotation semantics, caching behavior, audit logging, failure modes, and developer ergonomics.

Design an enterprise-wide secrets management architecture that supports hybrid cloud, multiple KMS vendors, automatic rotation, per-tenant scoping, approval workflows, emergency key revocation, and migration from static config files. Requirements: support 5,000 applications, 100,000 secrets, and 1,000 rotations per hour. Include APIs, scalability considerations, tenancy isolation, and migration strategy with minimal downtime.
