Security Engineering & Operations Topics
Operational security practices, secure systems implementation, threat modeling, penetration testing, vulnerability assessment, and security operations at production scale. Covers network security, endpoint security, secure architecture implementation, incident response mechanics, and security automation. Distinct from Security & Compliance (which addresses governance, compliance frameworks, and policy) and from Security Research & Innovation (which addresses novel techniques and research contributions).
Incident Response Forensics and Crisis Management
Covers the full spectrum of preparing for, detecting, investigating, containing, and recovering from security and operational incidents, plus managing their business and regulatory impact. Candidates should understand the incident response lifecycle including detection and monitoring, triage and prioritization, containment, eradication, recovery, and post incident review. This includes forensic evidence preservation and analysis practices such as secure collection of logs and artifacts, tamper proofing, chain of custody, immutable storage, timeline building, memory and disk examination fundamentals, and legal and regulatory considerations for evidence. It also covers designing infrastructure and tooling to enable rapid response at scale: logging and telemetry architecture, data retention policies, secure evidence storage, automated collection and alerting, integration with runbooks and response workflows, and readiness of teams and playbooks. Finally, it addresses crisis and stakeholder management skills: incident command and coordination across engineering, security, product, legal, customer support and executive stakeholders, internal and external communications and status updates, customer and regulator notification procedures, postmortem and lessons learned processes, tabletop exercises and drills, and leadership and decision making under pressure.
DevSecOps & Shift Left Security Practices
Understand DevSecOps principles: integrating security into every stage of development and deployment. Know how to shift security left: catching vulnerabilities in IDE, pre-commit, in CI/CD pipeline, rather than after deployment. Discuss how to make security frictionless for developers through automation, clear guidance, and fast feedback. Understand cultural aspects: security champions, developer enablement, and building security into the development process.
Infrastructure Security and Compliance
Designing, implementing, and operating security and compliance controls for infrastructure and delivery pipelines at scale. Topics include identity and access management, authentication and authorization patterns, role based access control and least privilege, secrets management and rotation, encryption for data at rest and in transit, network segmentation and microsegmentation, zero trust architecture, audit logging and retention, vulnerability scanning and patch and remediation workflows, endpoint protection, threat detection and monitoring, threat modeling and risk assessment, incident detection and response planning and runbooks, software supply chain security including artifact signing and dependency scanning and provenance, policy as code and automated security gates in continuous integration and continuous delivery pipelines, automated testing and validation of controls, and the trade offs between security controls and developer velocity. Also covers embedding and operationalizing compliance requirements from common regulatory frameworks and standards such as the General Data Protection Regulation, the Health Insurance Portability and Accountability Act, Service Organization Controls two, the Payment Card Industry Data Security Standard, and International Organization for Standardization two seven zero zero one, and how those requirements influence architecture, controls, automation, monitoring, and auditability as systems scale globally.
DevSecOps and Secure SDLC
Covers integrating security into the software development lifecycle and operational pipelines. Topics include securing continuous integration and continuous delivery pipelines, automated security testing such as static application security testing, dynamic application security testing, and software composition analysis, dependency and container image scanning, secrets management in pipelines, vulnerability management, security gates and shift left security practices. Also includes infrastructure as code security, runtime and deployment security, compliance automation, interpreting and tuning security tool output to reduce false positives, and designing secure development architecture that enables rapid delivery while maintaining required security controls.
Security Architecture and Data Protection
Design and governance of security across application and infrastructure layers. Topics include encrypting data at rest and in transit, key management and secrets handling, identity and access management and role based access control, secure service authentication, network segmentation and zero trust approaches, secure configuration and vulnerability management, threat modeling and secure design reviews, operational detection and incident response procedures, data residency and regulatory obligations for protecting payment and personally identifiable information, and collaboration between security engineering operations and legal functions. Candidates should discuss trade offs between security controls and user experience as well as how to scale security practices globally.
Trust Safety and Data Privacy Architecture
Covers the technical design of systems that protect users and reduce risk across identity, fraud, background checks, and privacy domains. Candidates should be prepared to describe identity verification and background check pipelines, fraud detection and response architectures, secure handling of personally identifiable information including encryption and key management, role based access controls and least privilege design, data minimization and retention policies, anonymization and privacy preserving analytics, incident response and forensics, and metrics for trust and safety operations. The topic includes how to integrate these capabilities into product flows, ensure regulatory compliance, and communicate risks to leadership.
Security Architecture Principles and Fundamentals
Core principles and foundational knowledge for designing secure systems and architectures. Candidates should understand defense in depth, zero trust, least privilege, separation of duties, secure by design and fail secure thinking. Topics include attack surface reduction, secure defaults, threat modeling methodologies and how to translate high level principles into concrete controls. Coverage includes access control models such as role based and attribute based approaches, authentication and authorization architectures, secrets and key management basics, classification of controls as preventive, detective, or corrective, and integration of controls across identity, network, host, application, and data layers. Expect discussion of how to prioritize security requirements, make trade offs between security, performance, cost, and usability, and incorporate security requirements into the system development lifecycle.
Security and Compliance Fundamentals
Comprehensive knowledge of foundational security principles, organizational practices, and compliance awareness that apply across engineering and operational domains. Candidates should understand authentication and authorization mechanisms, identity and access management including role based access control, the principle of least privilege, separation of duties, need to know patterns, and secure configuration hygiene. Technical controls such as encryption at rest and in transit, network security and segmentation, access controls, and audit logging should be understood along with how they map to compliance requirements and organizational policies. The topic includes basic incident response and reporting processes, threat awareness and threat modeling concepts, logging and monitoring fundamentals, and approaches to system hardening and secure deployment. It also covers policy foundations including what makes a strong security policy, introductory privacy and data protection concepts such as the General Data Protection Regulation and the California Consumer Privacy Act, data retention and deletion practices, and common compliance frameworks and regulations such as the Health Insurance Portability and Accountability Act, the Payment Card Industry Data Security Standard, and the Sarbanes Oxley Act. Candidates should be able to reason about tradeoffs between security and usability, explain how security choices interact with product design and user experience, and describe pragmatic ways to implement controls in engineering and operational workflows.
Incident Response and Security Reporting
Practices for documenting and communicating security incidents and vulnerability findings. Includes severity assessment, prioritization by business impact and exploitability, using scoring frameworks, preparing actionable remediation recommendations, and translating technical findings for non technical stakeholders. Covers how penetration testing and forensic analysis feed into response planning, risk management, and executive reporting during and after incidents.
