The concepts Shopify's AI Security Engineer loop assumes you know

What a Shopify interviewer expects you to reason from without being told: memory traffic, KV sizing, scheduling, parallelism. Foundation concepts are free to read, the advanced ones need Premium.

APPLICATION SECURITY

Foundational
Injection VulnerabilitiesInjection happens when data from an untrusted source is combined with code for an interpreter, such as a SQL engine, a shell or a template engine, and the interpreter treats part of the data as instructions. The structural fix is to keep code and data in separate channels: parameterised queries, argument arrays instead of shell strings, sandboxed templates. Prompt injection is the same failure in an interpreter that offers no separate channel, which is why its defences look different.
Foundational
Cross-Site Scripting and Output EncodingCross-site scripting (XSS) is injection into a browser: attacker-controlled content ends up in a page as executable script, running with the site's origin and the victim's session. It comes in stored, reflected and DOM-based forms. The fixes are contextual output encoding (frameworks do this by default), sanitisation when HTML must be rendered, and a strict Content Security Policy as a second layer. Chat interfaces that render model output as HTML or Markdown are a new and common source.
CoreSign in
Content Security Policy in DepthA Content Security Policy is a response header the browser enforces for one document: it decides which scripts, styles, frames and connections the page may use, blocks the rest and can report violations. Host allowlists failed in practice because allowed domains host code an attacker can reuse. A strict policy trusts scripts by per-response nonce or by hash, propagates trust with strict-dynamic, and adds object-src and base-uri. Trusted Types closes DOM sinks. CSP limits XSS impact; it does not fix XSS or stop data leaving.
Advanced🔒 Premium
How Browsers Separate Origins: SOP, CORS and CSRFThe same-origin policy lets a page send requests almost anywhere but stops its script reading responses from other origins. CORS is the server's way to relax that read restriction for chosen origins; it never stops a request being sent. CSRF is the attack that exploits sending: a cross-site page makes the victim's browser submit a request with the victim's cookies. The defences are separate: exact CORS allowlists for reads, and for writes a CSRF token, Fetch Metadata checks, strict content types and SameSite cookies as defence in depth.

INFRASTRUCTURE SECURITY

Foundational
What Containers Isolate, and What They Do NotContainers isolate processes using Linux namespaces, cgroups, capabilities, seccomp and security modules, but every container on a host shares one kernel. A kernel bug or a misconfiguration such as a privileged container, a mounted container runtime socket or a broad host mount lets code escape to the host. For untrusted code, including code written or run by AI agents, stronger boundaries such as gVisor's user-space kernel or Firecracker and Kata microVMs put a much smaller or separate kernel between the workload and the host.
Foundational
Sandboxing Untrusted CodeAgents that write and run code, notebooks that execute model output, and platforms that run customer code all execute code nobody reviewed. A sandbox makes that safe by combining a strong isolation boundary with an environment that has nothing valuable in it: no credentials, minimal files, no network or tightly allowlisted egress, resource and time limits, and disposal after use. Isolation answers whether code can escape; the environment answers what it can do without escaping.
CoreSign in
Cloud IAM and Privilege Escalation PathsCloud identity and access management decides what every user, service and workload can do, so it is the real perimeter of a cloud environment. Privilege escalation happens when a principal can use its permissions to gain more: attaching policies to itself, passing a powerful role to a resource it creates, changing code that runs under another role, or minting credentials. ML platforms are full of such paths because training and notebook roles are often broad. Least privilege, permission boundaries, organisation-level guardrails and path analysis keep them closed.
Advanced🔒 Premium
The Inference Stack as Attack SurfaceAn LLM inference service is a stack of components that all handle untrusted input: an API gateway, authentication and quotas, request and prompt processing, tokenizers, the model server, GPU drivers, caches, logging, and the management plane. Each layer has classic risks such as parsing bugs, exposed dashboards and broken tenancy, plus AI-specific ones: cost exhaustion, model extraction through the API, prompt leakage through shared caches, and data retained in logs. Threat-modeling the stack layer by layer turns 'secure the model' into concrete controls.

LLM APPLICATION SECURITY

Foundational
Insecure Output HandlingInsecure (or improper) output handling, LLM10 in the OWASP Top 10 for LLM Applications 2026 (LLM05 in 2025), is passing model output to a browser, database, shell, template engine, URL fetcher or other interpreter without the validation and encoding you would apply to user input. Because output is shaped by every author in the model's context, an attacker who can influence the context can reach those interpreters, recreating cross-site scripting, SQL injection, command injection and SSRF.
Foundational
Data Exfiltration Channels in LLM ApplicationsAn injected model that has read private data still needs a way to get it out. LLM applications offer many: explicit tools such as email or HTTP, URLs the model asks a tool to fetch, markdown images and links that clients load or users click, link previews, and content written somewhere the attacker can read. Closing these channels deterministically is one of the most reliable defences against prompt injection, because it works no matter how the injection was phrased.
Foundational
RAG SecuritySecuring retrieval-augmented generation means three things. Retrieval must enforce the asking user's permissions in code, with permissions copied into the index and kept in sync, tenants isolated and deletions propagated. Retrieved text must be treated as untrusted, because anyone who can write a source can inject instructions or misinformation. And the answer must be handled safely on its way out. Permission failures can expose data even when no prompt injection occurs.
CoreSign in
Sensitive Information DisclosureSensitive information disclosure, LLM02 in the OWASP Top 10 for LLM Applications (2025 and 2026), covers personal data, secrets, proprietary information and other users' data leaking through an LLM application. The leak paths include retrieval without authorization, context shared across users, prompt and response logs, caches, fine-tuning data, model memorisation, third-party providers and the answer itself. Controls minimise what enters each path and enforce access before data reaches the model.

DETECTION & RESPONSE

Foundational
Detection Engineering: From Hypothesis to Tested AlertDetection engineering turns knowledge of attacker behaviour into reliable alerts. Each detection starts from a behaviour attackers cannot easily avoid, depends on a data source that is confirmed to record it on the relevant assets, is tuned against history with narrow, owned exceptions, is tested by emulating the technique, and ships with a runbook and metrics. Managed as code, detections are reviewed, tested end to end, rolled out in shadow mode and retired when they stop earning their cost; ATT&CK is used to prioritise and to find gaps, not to colour a heatmap.
CoreSign in
MITRE ATT&CK and Sigma: a Shared Language for DetectionsMITRE ATT&CK is a knowledge base of adversary behaviour organised as tactics (goals) and techniques (how), now linked to detection strategies and the telemetry needed. Its 2026 releases split Defense Evasion into Stealth and Defense Impairment, giving Enterprise 15 tactics, and added AI-focused techniques. Sigma is a vendor-neutral rule format: a detection is written once in YAML and converted for each SIEM, with correlation rules for counts and sequences. Coverage means tested detections on collected data, not coloured cells.
Foundational
Incident Handling: Declare, Contain, Scope, Recover, LearnIncident handling turns an alert into a controlled response: declare against written criteria, assign an incident commander, contain with the least evidence-destroying action that stops harm, preserve volatile evidence, scope across hosts, identities and cloud accounts, eradicate persistence, recover from trusted states, and review blamelessly with tracked actions. NIST SP 800-61 Revision 3 (April 2025) frames this inside the Cybersecurity Framework 2.0 functions, so preparation, governance and improvement are part of incident response, not separate from it.
CoreSign in
Endpoint and Network Telemetry for DetectionEndpoint telemetry (process creation with command lines and parents, network connections per process, file and persistence changes, authentication and module loads) shows what ran and why. Network telemetry (flow records, DNS, proxy logs and TLS metadata) shows who talked to whom, how much and how regularly, even when payloads are encrypted. Sensors collect these through kernel callbacks and event tracing on Windows, eBPF and audit on Linux, and Endpoint Security on macOS. Attackers try to blind sensors and blend into allowed channels, so telemetry must be shipped off-host quickly, watched for silence, enriched and correlated.
