  1. Foundations: API Security & AI Fundamentals

    6 weeks
    Goals
    • Master OWASP API Security Top 10 and common API vulnerability classes
    • Understand transformer architecture, tokenization, and how LLM APIs work at a conceptual level

    • OWASP API Security Top 10 (2023 edition)
    • HuggingFace NLP Course (free)
    • API Security in Action by Neil Madden
    • OpenAI API documentation and safety best practices
    Milestone

    You can identify and articulate the top 10 API security risks and explain how an LLM API processes a request end-to-end.

  2. AI-Specific Threat Landscape

    6 weeks
    Goals
    • Study prompt injection taxonomy: direct, indirect, multi-turn, and system prompt leakage
    • Learn adversarial ML concepts including model extraction, membership inference, and data poisoning
    • Understand the OWASP Top 10 for LLM Applications and MITRE ATLAS framework
    Resources
    • OWASP Top 10 for LLM Applications (2025)
    • MITRE ATLAS (Adversarial Threat Landscape for AI Systems)
    • Simon Willison's blog on LLM security
    • Academic papers on prompt injection (Perez & Ribeiro et al.)
    Milestone

    You can perform a structured threat model of an AI API integration and identify attack vectors specific to LLM endpoints.

  3. Hands-On: Tools, Guardrails & Red Teaming

    8 weeks
    Goals
    • Configure API gateways with security policies for AI endpoints
    • Implement prompt injection detection using classifiers and rule-based systems
    • Build security guardrails using Guardrails AI, Llama Guard, or custom filters
    • Conduct red-team exercises against sample AI API deployments
    Resources
    • Kong Gateway documentation and security plugins
    • Guardrails AI documentation
    • Llama Guard model card and usage guides
    • NVIDIA Garak (LLM vulnerability scanner)
    • Burp Suite extensions for API testing
    Milestone

    You can deploy a secured AI API with authentication, rate limiting, input validation, output filtering, and demonstrate attack/defense scenarios.

  4. Enterprise Integration & Compliance

    6 weeks
    Goals
    • Design enterprise-grade AI API security architectures across multi-cloud environments
    • Implement DLP, audit logging, and SIEM integration for AI API traffic
    • Map AI API security controls to NIST AI RMF, EU AI Act, and SOC 2 requirements

    Milestone

    You can design and defend an enterprise AI API security architecture that meets regulatory requirements and passes an internal security review.

  5. Portfolio Building & Job Readiness

    4 weeks
    Goals
    • Complete 3-5 portfolio projects demonstrating end-to-end AI API security
    • Publish technical write-ups or a blog on novel AI API attack vectors or defenses
    • Prepare for interviews with scenario-based and technical deep-dive practice

    • Personal lab environment with OpenAI, HuggingFace, and AWS
    • GitHub portfolio with documented projects
    • Bug bounty platforms (HackerOne, Bugcrowd) for real-world practice
    • AI security community Discord/Slack channels
    Milestone

    You have a polished portfolio, published thought leadership, and can confidently handle interview scenarios at the advanced level.

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

AI API Security Proxy with Injection Detection

Intermediate

Build a reverse proxy that sits in front of an LLM API (OpenAI or HuggingFace), implementing authentication, rate limiting, prompt injection detection using a classifier, and output PII scanning. The proxy should log all requests and flag suspicious traffic.

~30h
API gateway designPrompt injection detectionRate limiting

LLM Red Team Toolkit

Advanced

Develop a Python-based toolkit that automates common LLM attack techniques (prompt injection, jailbreaking, system prompt extraction, data leakage probing) against a target API, generating structured vulnerability reports with severity ratings.

~40h
Adversarial testingAPI fuzzingVulnerability assessment

Secure RAG Pipeline Architecture

Intermediate

Design and implement a Retrieval-Augmented Generation pipeline with security at every layer: document access control, input sanitization for retrieved content, output filtering, and audit logging. Deploy using Terraform on AWS.

~35h
RAG securityInfrastructure-as-CodeContent filtering

AI API Threat Intelligence Dashboard

Intermediate

Build a real-time monitoring dashboard (using Datadog or Grafana) for AI API traffic that visualizes token usage patterns, detects anomalies, identifies potential abuse, and triggers automated alerts for security operations teams.

~25h
Security monitoringAnomaly detectionDashboard design

Multi-Tenant AI API Security Platform

Advanced

Architect and implement a multi-tenant platform where different organizations can securely access shared AI models with strict isolation, per-tenant rate limits, scoped permissions, independent audit logs, and tenant-specific guardrail policies.

~50h
Multi-tenancy designAuthorization architectureData isolation

Automated AI Security Regression Test Suite

Beginner

Create a test suite using pytest and custom prompt templates that automatically tests an AI API against known attack patterns (injection, extraction, toxicity) on every deployment, failing the pipeline if new vulnerabilities are detected.
