What You Will Learn
Multiple Clouds Require Multiple Solutions
NOTICE: SEC510: Public Cloud Security: AWS, Azure, and GCP was formerly known as SEC510: Multicloud Security Assessment and Defense. It is the exact same material but with two additional days of content! The new title betters reflect the course content.
SEC510: Public Cloud Security: AWS, Azure, and GCP teaches you how the major cloud providers work and how to securely configure and use their services and Platform as a Service (PaaS) offerings.
Organizations in every sector are increasingly adopting cloud offerings to build their online presence. However, although cloud providers are responsible for the security of the cloud, their customers are responsible for what they do in the cloud. Unfortunately, the providers have made the customer's job difficult by offering many services that are insecure by default. Worse yet, with each provider offering hundreds of different services and with many organizations opting to use multiple providers, security teams need a deep understanding of the underlying details of the different services in order to lock them down. As the landscape rapidly evolves and development teams eagerly adopt the next big thing, security is constantly playing catch-up in order to avert disaster.
SEC510 provides cloud security practitioners, analysts, and researchers with an in-depth understanding of the inner workings of the most popular public cloud providers: Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Students will learn industry-renowned standards and methodologies, such as the MITRE ATT&CK Cloud Matrix and CIS Cloud Benchmarks, then apply that knowledge in hands-on exercises to assess a modern web application that leverages the cloud native offerings of each provider. Through this process students will learn the philosophies that undergird each provider and how these have influenced their services.
The Big 3 cloud providers alone provide more services than any one company can consume. As security professionals, it can be tempting to limit what the developers use to the tried-and-true solutions of yesteryear. Unfortunately, this approach will inevitably fail as the product development organization sidelines a security entity that is unwilling to change. Functionality drives adoption, not security, and if a team discovers a service offering that can help get its product to market quicker than the competition, it can and should use it. SEC510 gives you the ability to provide relevant and modern guidance and guardrails to these teams to enable them to move both quickly and safely.
THIS COURSE WILL PREPARE YOU TO:
- Understand the inner workings of cloud services and Platform as a Service (PaaS) offerings in order to make more informed decisions in the cloud
- Understand the design philosophies that undergird each provider and how these have influenced their services in order to properly prescribe security solutions for them
- Discover the unfortunate truth that many cloud services are adopted before their security controls are fully fleshed out
- Understand Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP) in depth.
- Understand the intricacies of Identity and Access Management, one of the most fundamental concepts in the cloud and yet one of the last understood
- Understand cloud networking and how locking it down is a critical aspect of defense-in-depth in the cloud
- Analyze how each provider handles encryption at rest and in transit in order to prevent sensitive data loss
- Explore the service offering landscape to discover what is driving the adoption of multiple cloud platforms and to assess the security of services at the bleeding edge
- Understand the complex connections between cloud accounts, providers, and on-premise systems and the cloud
- Perform secure data migration to and from the cloud
- Understand Terraform Infrastructure-as-Code well enough to share it with your engineering team as a starting point for implementing the controls discussed in the course
NOTICE TO STUDENTS
- Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP) accounts are needed in order to do the hands-on exercises during this course. Students must create their cloud accounts prior to the start of class. Your ability to execute the hands-on exercises will be delayed if you wait to set up the accounts during a live class.
- These cloud accounts will incur additional fees from platform usage. The estimated cost for running the lab environment is roughly $25 for the course.
SEC510: Public Cloud Security: AWS, Azure, and GCP consolidates all of the concepts discussed in the lectures through hands-on labs. In the labs, students will assess a modern web application written with Next.js, React, and Sequelize that leverages the cloud native offerings of each provider. Each lab includes step-by-step guide as well as a "no hints" option for students who want to test their skills without further assistance. This allows students to choose the level of difficulty that is best for them and fall back to the step-by-step guide as needed.

Although SEC510 uses Terraform Infrastructure-as-Code to deploy and configure services in each cloud for the labs, students will not need in-depth knowledge of Terraform or need to understand any of the syntax used. However, students will be introduced at a high level to what this code accomplishes.
Syllabus (30 CPEs)
SEC510 starts with a brief overview of the Big 3 cloud providers. We will examine the factors driving adoption of multiple cloud providers and the rise in popularity of Azure and GCP, which historically have lagged far behind AWS. Students will then initialize their lab environment and deploy a modern web application to each of the Big 3 providers.
This leads into an analysis of the intricacies of Identity and Access Management (IAM), one of the most fundamental and misunderstood concepts in cloud security. Playing the role of an attacker in their lab environment, students will compromise real IAM credentials using application vulnerabilities and then use them to access sensitive data.
The remainder of this section will focus on how to leverage well-written IAM policies to minimize the damage caused by such attacks. Although the ultimate solution is to fix the bug in the application, these strategies can prevent a minor incident from becoming front-page news.

Section 2 covers how to lock down infrastructure within a virtual private network. As the public cloud IP address blocks are well known and default network security is often lax, millions of sensitive assets are unnecessarily accessible to the public Internet. This section will ensure that none of these assets belong to your organization.
The section begins by demonstrating how ingress and egress traffic can be restricted within each provider. Students will analyze the damage that can be done without these controls by accessing a public-facing database and creating a reverse shell session in each environment. We will then eliminate both attack vectors with secure cloud configuration.
In addition to introducing additional network defense-in-depth mechanisms, we will discuss cloud-based intrusion detection capabilities to address the network-based attacks we cannot eliminate. Students will analyze cloud traffic and search for indicators of compromise.

The first half of Section 3 covers all topics related to encryption in the cloud. Students will learn about each provider's cryptographic key solution and how it can be used to encrypt data at rest. Students will also learn how end-to-end, in-transit encryption is performed in the cloud, such as the encryption between clients, load balancers, applications, and database servers.
Proper encryption is not only critical for security; it is also an important legal and compliance consideration. This section will ensure that your organization has all of the information at its disposal to send the auditors packing.

This course section tackles the ever-changing trends in technology by providing in-depth coverage of a paradigm taking the industry by storm: Serverless. It balances the discussion of the challenges serverless introduces with the advantages it provides to secure product development and security operations.
The first half of the section covers serverless cloud functions in AWS Lambda, Microsoft Azure, and Google Cloud Functions. After introspecting the serverless runtime environments using Serverless Prey (a popular open-source tool written by the course authors), students will examine and harden practical serverless functions in a real environment.
The second half of the course section covers App Services, which often interplay with cloud functions. The section concludes with a detailed analysis of Firebase, an application platform with serverless offerings that has been loosely integrated with the Google Cloud Platform since its acquisition by Google in 2014.

"The move to leveraging multiple public cloud providers introduces new challenges and opportunities for security and compliance professionals. As the service offering landscape is constantly evolving, it is far too easy to prescribe security solutions that are not accurate in all cases. While it is tempting to dismiss the multicloud movement or block it at the enterprise level, this will only make the problem harder to control.
"Why do teams adopt additional cloud solutions in the first place? To make their jobs easier or more enjoyable. Developers are creating products that make money for the business, not for the central security team. If a team discovers a service offering that can help get its product to market quicker than the competition, it can and should use it. Security should embrace the inevitability of the multicloud movement and take on the hard work of implementing guardrails that enable the organization to move quickly and safely.
"The multicloud storm is coming, whether you like it or not."
"Very well spoken, super attentive, had a sense of humor. What more could you ask for. He really knew the content and when he didn't know something he wasn't afraid to let us know. Would love to take other courses with him." - Mike Schimmel, VMware
