Learning Serverless Security Hacking and Securing Serverless Cloud Applications on AWS, Azure, and Google Cloud (Joshua Arvin Lat)（Z-Library）

# Learning Serverless Security: Hacking and Securing Serverless Cloud Applications on AWS, Azure, and Google Cloud ## 【One-Line Pitch】 A hands-on, offensive-and-defensive security guide for developers, DevOps engineers, and security professionals who build or audit serverless applications on AWS, Azure, and Google Cloud—teaching you how real-world attacks happen and how to stop them through practical, lab-based exercises. ## 【Book Arc】 - **Opening (~0%–10%)**: Introduces the book's purpose—closing the serverless security knowledge gap—and lays out the full table of contents covering everything from common vulnerabilities to IAM exploitation and CI/CD security. - **Early (~10%–25%)**: Defines serverless computing and debunks common myths (e.g., "serverless is only for simple apps," "cold starts make it unusable"), then maps the cloud services and building blocks that enable serverless architectures across all three major providers. - **Early–Middle (~25%–40%)**: Explores architectural patterns (queue-based load leveling, fan-out, federated identity) and their security implications, then dives into the threat landscape: over-privileged permissions, business logic flaws, insecure network configs, and leaked credentials. - **Middle (~40%–50%)**: Examines specific attack vectors in depth—broken authentication (with real Cognito misconfiguration case studies), vulnerable dependencies, supply chain attacks, and how attackers chain these weaknesses into full account takeovers. - **Late (~50%–100%)**: Transitions into hands-on exploitation labs, starting with exposed AWS IAM credentials—setting up vulnerable-by-design environments, abusing overly permissive policies, and auditing CloudTrail logs to investigate incidents. ## 【Key Takeaways】 - **Serverless security is a shared responsibility model** (Early): The cloud provider secures the infrastructure, but you own the security of your functions, configurations, and identity management—misunderstand this boundary and you'll leave critical gaps. - **Common architectural patterns introduce predictable vulnerabilities** (Early–Middle): Queue-based load leveling, fan-out, and federated identity patterns each have known failure modes—unvalidated queue inputs, hardcoded credentials, and misconfigured IdP integrations—that attackers actively exploit. - **Over-privileged permissions are the #1 enabler of severe breaches** (Middle): Excessively permissive IAM roles and policies let attackers escalate from a single compromised credential to full account takeover; least-privilege enforcement is non-negotiable. - **Broken authentication remains a critical serverless risk** (Middle): Misconfigured identity services like AWS Cognito (e.g., leaving self-registration enabled) have led to real-world privilege escalation and account takeovers—disable what you don't need and enforce MFA. - **Leaked credentials come from many sources, not just code** (Middle): Misconfigured storage buckets, frontend code, public repositories, and phishing all feed attackers with valid credentials that bypass traditional perimeter defenses. - **Vulnerable dependencies are a silent, long-term threat** (Middle): Outdated libraries chosen for compatibility reasons—or simply forgotten—expose applications to known vulnerabilities for years; supply chain attacks can hide malicious code in dependencies you trust. - **Serverless doesn't eliminate network security concerns** (Middle): Functions still need proper VPC/VNet configuration to securely access private resources—misconfigurations here create new attack surfaces even without traditional open ports. ## 【Reading Tips】 - **Skim the service catalogs** (Early chapters): The extensive lists of AWS, Azure, and GCP serverless services are reference material—scan them for awareness, but don't memorize; you'll encounter the important ones again in security contexts. - **Deep-read the threat chapters** (Middle): Chapters on serverless security risks and broken authentication contain the conceptual core of the book—pay close attention to real-world case studies and the "defensive security standpoint" recommendations. - **Treat the lab chapters as hands-on workshops** (Late): The IAM exploitation chapter is designed for active learning—set up the vulnerable-by-design environment and follow along rather than just reading; this is where the offensive techniques become practical skills. - **Watch for cross-provider comparisons**: The book consistently shows how the same security issue manifests on AWS, Azure, and Google Cloud—use these tables to build a mental model of provider-specific differences. - **Note the OWASP Serverless Top 10 alignment**: Security issues are framed against industry standards, so use this book to map your existing OWASP knowledge onto the serverless context. ## 【Coverage Limits】 The excerpts cover the book's opening through roughly the middle (approximately 50%), including foundational concepts, threat taxonomy, and the beginning of hands-on IAM exploitation labs. Later chapters on CI/CD pipeline security, supply chain defense, and comprehensive audit strategies are referenced but not detailed in this guide. ##
