SEC510: Multicloud Security Assessment and Defense Waitlist

Mon, September 21 - Wed, September 23, 2020

Course Syllabus  ·  18 CPEs  ·   Lab Requirements
Instructor: Brandon Evans

SEC510: Multicloud Security Assessment and Defense 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 the 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.

Organizations in every sector are increasingly adopting cloud offerings to build their online presence on the shoulders of giants. 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 is rapidly evolving and development teams are eager to adopt the next big thing, security is constantly playing catch-up in order to avert disaster.

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 organization 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 Platform-as-a-Service offerings in order to make more informed decisions in the cloud
  • Understand the design philosophies that undergird each provider and how these have influenced the providers' 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 Azure and the Google Cloud Platform, both of which we will cover extensively
  • Receive thousands of lines of Infrastructure-as-Code for each platform that you can plug into your organization

Student Notices and Requirements

  • 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.

You Will Be Able To:

  • Understand the intricacies of Identity and Access Management, one of the most fundamental concepts in the cloud and yet one of the most commonly misunderstood
  • 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 the services at the bleeding edge
  • Understand the complex connections between cloud accounts, providers, and on-premises 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

Hands-on Labs

SEC510 solidifies every concept 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 a 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.

You Will Receive With This Course:

  • Electronic courseware
  • Digital download package

Overview

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.

Overview

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.

Overview

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 considerations. This section will ensure that your organization has all of the information at its disposal to send the auditors packing.

We round off the course by covering some miscellaneous cloud concepts that every security professional should know: securing cloud storage, attacking and defending serverless functions, and how to use automated tools to assist in the assessments of your cloud environments.

Author Statement

"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."
