Description

A focused course, tailored for you

The Senior Security Engineer Feature Review Playbook

Run threat-model, control-map and evidence-trail security reviews of merchant-facing platform features without dropping a sprint.

You are the senior security engineer the PM wants in the room before the feature ships, but the review keeps slipping because the threat model, the control map, and the audit evidence row live in three different tools and none of them references the others.

Tailored to your situation. Access within 24 hours. 30-day money-back.

Includes a hand-built implementation playbook delivered alongside course access, generated for your specific situation.

Why this course

A senior security engineer on a commerce platform is the only person in the room who can answer four questions at once. Does this feature widen PCI scope. Does it break the SOC 2 logical-access narrative your auditor signed off on last cycle. Does it expose merchant data across tenants in a way the threat model has to cover. Does it leave an evidence trail an external assessor can pull without paging you. The skill the role demands is not threat modelling on its own and not control mapping on its own. It is running the three of them as one artefact so the PM can ship the feature, the auditor can pull the evidence, and you can close the ticket the same week it landed. Most teams improvise this for every feature, which is why the same review consumes a week per launch and why audit prep becomes a six-week archaeology project every cycle. This playbook is the engineering build for that exact workflow, written for senior engineers who already know the frameworks and need the production-grade method that ties them together.

What you walk away with

Run a full security review of a merchant-facing feature in a single sprint, end to end, with threat model, control map, and audit evidence row all referencing each other.
Produce a written go or no-go memo the PM, the auditor, and your security lead read the same way without follow-up questions.
Map any feature to PCI DSS 4.0 requirements, SOC 2 CC and A criteria, and your internal control catalogue in one pass using the worked templates.
Hand a SOC 2 or PCI assessor a self-contained evidence packet per feature so audit prep stops being archaeology.
Cut the review queue backlog so launches stop waiting on security and security stops waiting on screenshots.

The 12 modules

Module 1. What a clean security review actually looks like at platform scale

Walks through one fully worked review of a merchant-facing checkout feature, from spec link to signed memo. Shows the four artefacts produced (data-flow diagram, threat model, control map, evidence packet), where each one lives, who reads each one, and how they reference each other. Sets the bar the rest of the course teaches you to hit on every feature you sign off this fiscal year.

Module 2. Reading a merchant-facing feature spec for security shape

Teaches the first-pass read of a feature spec that pulls out cardholder-data flow, cross-tenant data exposure, new trust boundaries, new external dependencies, new authentication surfaces, and new privileged operations. Includes a one-page security-shape worksheet you fill in straight from the PRD before opening any other tool. Eliminates the back-and-forth questions that usually eat the first day of a review.

Module 3. Data-flow diagrams that double as audit artefacts

Builds the data-flow diagram once, in a form that satisfies a threat-modelling session, the PCI scoping conversation, and the SOC 2 system description appendix. Covers naming conventions, trust-boundary placement, what to leave out, what an assessor will challenge, and how to keep the diagram alive across feature iterations instead of regenerating it every cycle.

Module 4. STRIDE-per-element at platform scale, fast

Runs STRIDE-per-element on the worked checkout example, but with the moves that make it survive a multi-tenant platform context: confused-deputy patterns in admin APIs, tenant-isolation failures, OAuth scope leakage in app platforms, log-injection in shared logging, supply-chain takeover via build artefacts. Each threat ends in a control reference, not just a finding.

Module 5. Mapping to PCI DSS 4.0 without scope creep

Teaches the scope decision first, then the requirement mapping. Walks through 4.0 changes that hit merchant platforms hardest (targeted risk analyses, customised approach, page-script integrity for checkout, MFA for non-console admin, retired SAQ A simplifications). Gives you the worksheet that decides which 4.0 requirements actually apply to this feature and which are inherited from the platform's annual ROC.

Module 6. Mapping to SOC 2 CC and A series without restating the system description

Shows how to attach a feature to the trust-services criteria already covered by the platform SOC 2 report, where to extend the system description, when to write a complementary control, and how to keep the change log clean so the bridge letter at year-end takes hours not weeks. Includes a cheat sheet of which CC criteria almost every merchant-facing feature touches and which it almost never does.

Module 7. Writing the control map that PMs, auditors, and on-call all read

Combines the PCI and SOC 2 mappings with the internal control catalogue into a single control map per feature. Covers the column structure, the level of evidence each row needs, what to do when a control is shared across features, and how to handle compensating controls so they survive the next audit rotation. The output is the artefact PMs use to plan remediation and auditors use to pull evidence.

Module 8. Designing the evidence trail at build time, not audit time

Walks through the design moves that make evidence cheap forever: structured audit logs with stable field names, immutable-by-default access trails, signed deploy attestations, ticket-to-commit-to-deploy linkage, and the small set of dashboards an assessor will pull on day one. Includes the evidence packet template you hand over per feature and the directory layout that survives staff turnover.

Module 9. Reviewing OAuth, scopes, and app-platform integrations

Focused module on app-platform feature reviews where third-party developers can install code that touches merchant data. Covers scope design, install-time consent, runtime authorisation, replay defences, token storage, and incident-response patterns when an installed app is compromised. The threat model produced here is reusable across every new app-platform capability you ship for the rest of the year.

Module 10. Reviewing privileged admin paths and break-glass

Covers feature reviews that touch internal admin tooling, support impersonation, and break-glass access into merchant accounts. Walks through approval workflows, time-bound elevation, session recording, the controls that satisfy both SOC 2 CC6 and the privileged-access expectations PCI 4.0 has tightened. Produces a privileged-path threat model template you reuse across every admin feature.

Module 11. Writing the go or no-go memo the PM actually reads

Teaches the one-page format that closes the review: outcome up top, scope of the review, residual risks accepted, controls deferred and to which sprint, evidence index, sign-offs. Includes language patterns for refusing a launch without burning the PM relationship and for accepting a residual risk in a way the auditor will not flag next cycle. The same memo doubles as the audit walkthrough script.

Module 12. Running the review queue so launches stop waiting on security

Closes the course on the operational side. Covers queue triage at senior-engineer scale, what to delegate to a junior, what to defer to a security architect, how to measure review throughput honestly, when to push back on a feature that should not have reached the queue. Includes the metrics dashboard that lets you tell your manager and the head of engineering the same story about where security review time is going.

A new merchant-facing checkout flow lands in staging Friday and needs a clean security sign-off by sprint end. Modules 1 through 4 plus 11.

PCI 4.0 transition is the cycle your platform is closing right now and you are the engineer the GRC team pings for the targeted risk analyses. Modules 3, 5, 7, and 8.

The next SOC 2 Type II window opens and your auditor flagged that feature-level evidence has been ad-hoc. Modules 6, 7, 8, and 11.

A partner app installed via your app platform leaked a merchant access token and the post-mortem feeds into every future app-platform review. Module 9, plus 4 and 11.

Modules 9 through 12 cover the specialised review paths and the operational queue and close the course in a third sprint.

Before and after

Before

Every feature review consumes a week of senior-engineer time, threat model and control map and evidence row never reference each other, and audit prep becomes a six-week archaeology project searching for which Notion page covers which feature.

After

Every feature review closes in a sprint with one self-contained artefact set, the go or no-go memo doubles as the audit walkthrough script, and audit prep is reading the index of memos you already wrote.

What happens if you do not address this

The review queue keeps growing, PMs route around security by lowering the bar for what counts as a sign-off, and the next assessor cycle surfaces feature-level evidence gaps the platform has to remediate in compressed time. The cost is paid in engineering sprints either way, the playbook moves that cost from audit-time scramble to design-time discipline.

Who it is for

Senior security engineers on commerce, payments, or merchant-platform teams who sign off on feature reviews, contribute to threat models, own controls that touch PCI DSS 4.0 and SOC 2, and carry an on-call rotation. You already know STRIDE, you already know how to read an OAuth flow for confused-deputy bugs, you already know what an audit walkthrough sounds like. What you do not have is a repeatable shape for running all three artefacts together at platform engineering scale.

Who this is NOT for. Not for people new to application security or running their first threat model. Not for compliance analysts who do not write code. Not for security leadership looking for a program design document, this is hands-on engineering work. Not for engineers on internal-only enterprise apps, the playbook is built for high-blast-radius merchant-facing systems.

How it arrives

Text-based course in the Art of Service learning environment, plus downloadable templates and worked examples for every module, plus the hand-built implementation playbook delivered alongside course access.

Time investment. Approximately 14 to 18 hours over three sprints. The first reviewed feature you run with the playbook recovers the time investment in the same sprint.

Why $199 is the right number

Internal training rarely covers the integration of threat modelling, framework mapping, and evidence design as one workflow. Vendor courses on PCI 4.0 or SOC 2 teach the framework but not the engineering practice that produces the artefacts a senior engineer signs off. This playbook is the engineering build for the workflow itself, tuned to merchant-facing platform context, with the templates and the implementation playbook hand-built for your feature classes.

FAQ

I already run threat models, what is new here?

The new part is running the threat model, the control map, and the evidence row as one artefact set, in a form an external assessor can use without your help. The course assumes you know STRIDE.

Do I need to be on PCI scope to get value?

No. The PCI 4.0 modules are useful if you touch cardholder-data flow, the SOC 2 and OAuth and privileged-path modules apply to any merchant-facing platform feature even if you are out of PCI scope.

Is this tied to one specific platform?

No. The playbook is written for senior security engineers on any high-volume merchant-facing platform. The implementation playbook delivered with course access is tuned to the feature classes your team reviews.

What if my company already has a security review template?

Bring it. The course shows you how to integrate the templates with an existing review process rather than replace it. Most teams keep their intake form and replace the artefacts produced downstream.
