GIAC Defensible Security Architecture (GDSA)

What You Will Learn

NOTE: The term “architecture” is interpreted differently by different organizations and in various regions of the world. This course focuses on strategic and technical application and use cases, including fine-tuning and implementing various infrastructure components and cyber defense techniques. If you are expecting the course to focus exclusively on strategic solution placement and use cases, the course is not for you.

SEC530: Defensible Security Architecture and Engineering is designed to help students establish and maintain a holistic and layered approach to security. Effective security requires a balance between detection, prevention, and response capabilities, but such a balance demands that controls be implemented on the network, directly on endpoints, and within cloud environments. The strengths and weaknesses of one solution complement another solution through strategic placement, implementation, and fine-tuning.

To address these issues, this course focuses on combining strategic concepts of infrastructure and tool placement while also diving into their technical application. We will discuss and identify what solutions are available and how to apply them successfully. Most importantly, we’ll evaluate the strengths and weaknesses of various solutions and how to layer them cohesively to achieve defense-in-depth.

The changing threat landscape requires a change in mindset, as well as a repurposing of many devices. Where does this leave our classic perimeter devices such as firewalls? What are the ramifications of the “encrypt everything” mindset for devices such as Network Intrusion Detection Systems?

In this course, students will learn the fundamentals of up-to-date defensible security architecture and how to engineer it. There will be a heavy focus on leveraging current infrastructure (and investment), including switches, routers, and firewalls. Students will learn how to reconfigure these devices to significantly improve their organizations’ prevention capabilities in the face of today’s dynamic threat landscape. The course will also delve into the latest technologies and their capabilities, strengths, and weaknesses. You will come away with recommendations and suggestions that will aid in building a robust security infrastructure.

While this is not a monitoring course, it will dovetail nicely with continuous security monitoring, ensuring that security architecture not only supports prevention but also provides the critical logs that can be fed into a Security Information and Event Management (SIEM) system in a Security Operations Center.

Multiple hands-on labs conducted daily will reinforce key points in the course and provide actionable skills that students will be able to leverage as soon as they return to work.

You Will Be Able To

  • Analyze a security architecture for deficiencies
  • Implement technologies for enhanced prevention, detection, and response capabilities
  • Comprehend deficiencies in security solutions and understand how to tune and operate them
  • Apply the principles learned in the course to design a defensible security architecture
  • Determine appropriate security monitoring needs for organizations of all sizes
  • Maximize existing investment in security architecture by reconfiguring existing assets
  • Determine capabilities required to support continuous monitoring of key Critical Security Controls
  • Configure appropriate logging and monitoring to support a Security Operations Center and continuous monitoring program

While the above list briefly outlines the knowledge and skills you will learn, it barely scratches the surface of what this course has to offer. Hands-on labs throughout the course will reinforce key concepts and principles, as well as teach you how to use key scripting tools.

When your SEC530 training journey is complete, and your skills are enhanced and honed, it will be time to go back to work and deliver on the SANS promise that you’ll be able to apply what you learned in this course the day you return to the office.

GIAC Defensible Security Architecture

“The GIAC Defensible Security Architecture (GDSA) certificate is an industry certification that proves an individual is capable of looking at an enterprise defense holistically. A GDSA no longer emphasizing security through a single control but instead applies multiple controls ranging from network security, cloud security, and data-centric security approaches to properly prevent, detect, and respond. The end result is defense-in-depth that is maintainable and works.” – Justin Henderson, SANS SEC530 Course Author

“Holders of the GIAC Defensible Security Architect (GDSA) certification have proved to be all-round defenders, capable of designing, implementing and tuning an effective combination of network-centric and data-centric controls to balance prevention, detection, and response. Certified GDSA professionals are versatile blue-teamers and cyber defenders possessing an arsenal of skills to protect an organization’s critical data, from the endpoint to the cloud, across networks and applications. Armed with these skills, certified GDSA individuals possess, not only a strategic but also a tactical, hands-vision, that empowers them to continually improve an organization’s security posture, knowing how to best defend now and in the future.” – Ismael Valenzuela, SANS SEC530 Course Author

  • Experience with Linux from the command line

Laptop Requirements

Important! Bring your own system configured according to these instructions!

A properly configured system is required to fully participate in this course. If you do not carefully read and follow these instructions, you will likely leave the class unsatisfied because you will not be able to participate in hands-on exercises that are essential to this course. Therefore, we strongly urge you to arrive with a system meeting all the requirements specified for the course.

A properly configured system is required for each student participating in this course. Before coming to class, carefully read and follow these instructions exactly.

Host Operating System: Latest version of Windows 10, macOS 10.15.x or later, or Linux that also can install and run VMware virtualization products described below. Note: Apple systems using the M1 processor cannot perform the necessary virtualization at this time and cannot be used for this course. It is necessary to fully update your host operating system prior to the class to ensure you have the right drivers and patches installed to utilize the latest USB 3.0 devices. Those who use a Linux host must also be able to access exFAT partitions using the appropriate kernel or FUSE modules. You also must have 8 GB of RAM or higher for the VM to function properly in the class.

It is critical that your CPU and operating system support 64-bit so that our 64-bit guest virtual machine will run on your laptop.

In addition to having 64-bit capable hardware, AMD-V, Intel VT-x, or the equivalent must be enabled in BIOS/UEFI.

Download and install either VMware Workstation Pro 15.5.x, VMware Player 15.5.x or Fusion 11.5.x or higher versions before class. If you do not own a licensed copy of VMware Workstation or Fusion, you can download a free 30-day trial copy from VMware. VMware will send you a time-limited serial number if you register for the trial at their website.

Other virtualization software, such as VirtualBox and Hyper-V, are not appropriate because of compatibility and troubleshooting problems you might encounter during class.

VMware Workstation Pro and VMware Player on Windows 10 is not compatible with Windows 10 Credential Guard and Device Guard technologies. Please disable these capabilities for the duration of the class, if they’re enabled on your system, by following instructions in this document.

MANDATORY SEC530 SYSTEM REQUIREMENTS:

  • CPU: 64-bit 2.0+ GHz processor or higher-based system is mandatory for this class (Important – Please Read: a 64-bit system processor is mandatory)
  • BIOS/UEFI: VT-x, AMD-V, or the equivalent must be enabled in the BIOS/UEFI
  • RAM: 8 GB (gigabytes) of RAM or higher is mandatory for this class (Important – Please Read: 8 GB of RAM or higher is mandatory)
  • Wireless Ethernet 802.11 B/G/N/AC
  • USB 3.0 Ports highly recommended
  • Disk: 40 Gigabytes of free disk space
  • Administrative access to disable any host-based firewall
  • VMware Workstation Pro 15.5.X+, VMware Player 15.5.X+ or Fusion 11.5+

Your course media will now be delivered via download. The media files for class can be large, some in the 40 – 50 GB range. You need to allow plenty of time for the download to complete. Internet connections and speed vary greatly and are dependent on many different factors. Therefore, it is not possible to give an estimate of the length of time it will take to download your materials. Please start your course media downloads as you get the link. You will need your course media immediately on the first day of class. Waiting until the night before the class starts to begin your download has a high probability of failure.

SANS has begun providing printed materials in PDF form. Additionally, certain classes are using an electronic workbook in addition to the PDFs. The number of classes using eWorkbooks will grow quickly. In this new environment, we have found that a second monitor and/or a tablet device can be useful by keeping the class materials visible while the instructor is presenting or while you are working on lab exercises.

Author Statement

“In our many years of experience assessing the security posture of organizations, responding to incidents, and ramping up security operations, we’ve seen the futility of trying to monitor and defend against modern adversaries when the architecture in place has not been designed with security in mind. Likewise, we’ve continually seen that organizations that suffer massive breaches and business disruption often focused their emphasis prior to the breach on perimeter protection and prevention mechanisms but lacked defensible security architecture.

“We’ve designed this course to address this gap. In six days filled with case studies, winning techniques, instructor-led demos, and plenty of hands-on labs (including a NetWars-based Defend-the-Flag challenge), students will learn how to design, build, and harden networks, infrastructure, and applications that can truly be called ‘defensible.’

“As practitioners, we know that theory is not enough, so we’ve made sure that this class is focused on real-world implementations of network-centric, data-centric, and zero-trust security architecture mapped to best practices and standards, but also based on our many years of experience on what works and what doesn’t. You’ll find that this makes the content appropriate and relevant for the reality of a wide variety of organizations and roles.”
