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.
Security Incident Investigation and Remediation
Focuses on systematic investigation methodology and the distinction between immediate mitigation and long term prevention. Topics include collecting and preserving evidence, establishing a reliable timeline, identifying affected systems, performing root cause analysis, containment versus remediation, and documenting findings. Covers basic digital forensics principles and chain of custody, techniques for reducing blast radius and restoring service as a short term response, and planning permanent fixes to prevent recurrence. Also addresses privacy incident investigation practices such as interviewing stakeholders, assessing regulatory and compliance implications, timeliness and documentation requirements, remediation planning, and using post incident analysis to improve processes and controls.
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.
Authentication and Authorization
Cover core concepts and implementation trade offs for securing backend services. Candidates should demonstrate understanding of token based authentication and server side session strategies, how to securely issue and rotate credentials, techniques for revocation and refresh, secure storage of secrets, use of third party identity providers, common threat mitigations such as cross site request forgery protection and secure transmission practices, and design patterns for role based and attribute based access control. Interviewers will evaluate the candidate ability to reason about scalability and revocation trade offs and to design secure application programming interface permission checks.
Security Incident Response and Operations
Covers the practices, processes, and tooling for responding to security incidents and operating a security capability. Topics include the security incident lifecycle of preparation, detection, analysis, containment, eradication, recovery, and post incident review; development and execution of playbooks and runbooks tailored to threat types; severity classification and decision criteria for escalation; evidence preservation and forensic analysis and chain of custody; crisis communication to stakeholders and regulators; notification and regulatory compliance considerations; and coordination with legal, privacy, communications, and executive leadership. Also includes operational aspects of building and staffing a security operations center, on call schedules and escalation, ticketing and case management, leadership and coordination during major incidents, running blameless post incident reviews to identify systemic improvements, and integration of security incident learnings into engineering and operations.
Distributed System and Microservices Security
Focuses on security considerations for distributed systems, APIs, containers, and microservice ecosystems. Includes authentication and authorization approaches for APIs and service to service communication, token models and OAuth and JSON web tokens, API gateway and rate limiting strategies, secrets management and secure configuration, network segmentation and service mesh security, container and runtime image hardening, Kubernetes and orchestration security, vulnerability scanning and patch management, secure logging and tracing practices, dependency supply chain security, and compliance and governance implications. Emphasizes how security control implementation differs between monoliths and distributed architectures.
Authentication and Access Control
Comprehensive coverage of methods, protocols, design principles, and practical mechanisms for proving identity and enforcing permissions across systems. Authentication topics include credential based methods such as passwords and secure password storage, Multi Factor Authentication, one time passwords, certificate based and passwordless authentication, biometric options, federated identity and single sign on using Open Authorization, OpenID Connect and Security Assertion Markup Language, and service identity approaches such as Kerberos and mutual Transport Layer Security. Covers token based and session based patterns including JSON Web Token and session cookies, secure cookie practices, token lifecycle and refresh strategies, token revocation approaches, refresh token design, and secure storage and transport of credentials and tokens. Authorization and access control topics include role based access control, attribute based access control, discretionary and mandatory access control, access control lists and policy based access control, Open Authorization scopes and permission modeling, privilege management and the principle of least privilege, and defenses against privilege escalation and broken access control. The description also addresses cryptographic foundations that underlie identity systems including symmetric and asymmetric cryptography, public key infrastructure and certificate lifecycle management, secure key management and rotation, and encryption in transit and at rest. Common threats and mitigations are covered, such as credential stuffing, brute force attacks, replay attacks, session fixation, cross site request forgery, broken authentication logic, rate limiting, account lockout strategies, secrets management, secure transport, and careful authorization checks. Candidates should be able to design authentication and authorization flows for both user and service identities, evaluate protocol and implementation trade offs, specify secure lifecycle and storage strategies for credentials and tokens, and propose mitigations for common failures and attacks.
Production Incident Management
Production/service incident response: how an on-call engineer detects, triages, and resolves outages or reliability degradation. Covers detection via monitoring metrics, logs, and distributed traces; mitigation via rollbacks, circuit breakers, feature flags, or network ACLs; incident communication and stakeholder updates; root-cause analysis; and blameless postmortems. No adversary, no malware, no legal evidence chain: the concern is system failure and reliability, not intrusion or malicious activity.
Static Application Security Testing
Focuses on static analysis of source code and binaries to identify security weaknesses before deployment. Topics include how static application security testing tools detect common weakness patterns, configuration of scans, choosing when to run scans in the development lifecycle such as pre commit hooks and continuous integration pipelines, techniques to reduce and triage false positives, integrating findings into developer workflows and issue trackers, policy enforcement and governance when scaling scanning across many projects, limitations of static analysis and complementary controls, and strategies for developer education and remediation tracking.
