Cyber reskilling and upskilling are significant concerns for enterprises both large and small. Technologists must have a broad range of knowledge and certain basic skills in multiple areas. Every member of a security team, increasingly extended into Information Technology and DevOps, must prepare to ensure that any system, software, or infrastructure that is coded, built, and deployed is resilient to attack. Team members must have the knowledge necessary to identify the adversaries in their midst, which requires knowledge of the adversaries' tactics, techniques, and procedures, as well as familiarity with real-world tools that reveal their activities within the enterprise. Adversaries must be contained when uncovered-controlling their lateral movement and limiting the extent of their infiltration minimizes the risks of disclosure, alteration, and destruction of mission-critical enterprise data. Critically, having all hands on deck is key to eradicating the adversary, remediating compromised systems, and recovering lost assets. Prevent. Detect. Respond.

What You Will Learn

The experience of continuous adversary activity, of increasing magnitude, leading to frequent attacks, and the inevitable compromise which too often results in data loss and leakage. Enterprises must have cross-trained professionals fully prepared to contribute meaningfully to CERT/CSIRT activities when required. Experienced technologists who are exploring cyber career pathways and looking for hands-on practical experience with cutting-edge tools of the trade will find what they need in SEC501: Advanced Security Essentials-Enterprise Defender. It is the only SANS course that provides training across cybersecurity sub-disciplines in the tools and techniques used daily to defend the enterprise. Full-day course topics cover defending network architecture, penetration testing, security operations, DFIR/CERT/CSIRT, and malware analysis. Twenty five labs, conducted in-class, provide hands-on experience with real-world tools (e.g., Cisco routers, Covenant, Metasploit, Nessus, Nmap, Procmon, Snort, SOF-ELK, TShark, Wireshark, etc.) in each of these areas, demonstrating:

  • active defense
  • attacks against network devices (and defenses)
  • digital artifact collection
  • forensic data recovery
  • interactive behavioral analysis of malware
  • intrusion detection and Snort signature creation
  • log aggregation and correlation
  • manual code reversing

  • Overview

    Proper design and configuration of network devices protects both the components being configured and the rest of the enterprise that depends on those devices to defend other components from attacks. In other words, a good house needs a good foundation!

    In this course section we will discuss published security benchmarks, vendor guidance to secure various products, and regulatory requirements and how they impact defending infrastructure against specific attacks. To illustrate these points, we will look in detail at securing and defending a router infrastructure against a number of device- and network-based attacks. Securing private and public cloud infrastructure against common attacks will also be discussed.

  • Overview

    Security is all about understanding, mitigating, and controlling the risk to an enterprise's critical assets. An enterprise must understand the changing threat landscape and have the capacity to compare it against its own vulnerabilities that could be exploited to compromise the environment. This course section will present the variety of tests that can be run against an enterprise, and show how to perform effective penetration tests to better understand the security posture for network services, operating systems, and applications. In addition, we will talk about social engineering and open-source intelligence activities to better emulate increasingly prevalent threats to users.

    Finding basic vulnerabilities is easy but not necessarily effective if these are not the vulnerabilities attackers exploit to break into a system. Advanced penetration testing involves understanding the variety of systems and applications on a network and how they can be compromised by an attacker. Students will learn to scope and plan their test projects, perform external and internal network penetration testing and web application testing, and pivot through the environment like real-world attackers. And while penetration testing is critical to identify an enterprise's exposure points, students will also learn how to prioritize and fix these vulnerabilities to increase the enterprise's overall security.

  • Overview

    Traffic analysis and intrusion detection used to be treated as a separate discipline within many enterprises. Today, prevention, detection, and response must be closely knit, so that once an attack is detected, defensive measures can be adapted and proactive forensics implemented so the enterprise can continue to operate. This course section will start with a brief introduction to network security monitoring, followed by a refresher on network protocols, with an emphasis on fields to look for as security professionals. We will use tools such as tcpdump and Wireshark to analyze packet traces and look for indicators of attacks. We will also use a variety of detection and analysis tools as well as explore Snort as a Network Intrusion Detection System and examine rule signatures in-depth., Students will also conduct network forensics, and make use of the SOF-ELK platform to demonstrate the power of Security Information and Event Management tools.

  • Overview

    Enterprises rely on their CERT/CSIRT to find, scope, contain, and eradicate evil from their networks. Incident investigators employ DFIR practices to determine what happened: DFIR teams conduct investigations to find evidence of compromise, remediate the environment, and provide data to generate local threat intelligence for operations teams in order to continuously improve detection. While traditionally seen as a finite process, incident response is now viewed as ongoing, with DFIR professionals searching for evidence of an attacker that has existed in the environment without detection by applying new threat intelligence to existing evidence. This is the crux of the concept known as "threat hunting."

    This section begins with a discussion of Active Defense approaches in some detail, then presents the core concepts of DFIR. We will explore some of the hundreds of artifacts that can give forensic investigators specific insight about what occurred during an incident. Students will learn how incident response currently operates, after years of evolving, in order to address the dynamic procedures used by attackers to conduct their operations. We will also look at how to integrate DFIR practices into a continuous security operations program. Next, a cyclical, six-step incident response process is presented. Each step will be examined in detail, including practical examples of how to apply it. Finally, students will learn about the artifacts that can best be used to determine the extent of suspicious activity within a given environment and how to migrate techniques to a large data set for enterprise-level analysis.

  • Overview

    Malicious software is responsible for many incidents in almost every type of enterprise. Types of malware vary widely, from Ransomware and Rootkits to Crypto Currency Miners and Worms. In this course section, we will define each of the most popular types of malware and walk through multiple examples. The four primary phases of malware analysis will be covered: Fully Automated Analysis, Static Properties Analysis, Interactive Behavior Analysis, and Manual Code Reversing. Students will complete various in-depth labs requiring them to fully dissect a live Ransomware specimen from static analysis through code analysis. They will also gain hands-on experience with manipulating the malware through behavior analysis techniques, and in decrypting files encrypted by Ransomware by extracting the keys through reverse engineering. All steps are well defined and tested to ensure that the process to achieve these goals is actionable and digestible.

    Exercises
    • Static Properties Analysis of Ransomware
    • Interactive Behavior Analysis of Ransomware - Part I
    • Interactive Behavior Analysis of Ransomware - Part II
    • Manual Code Reversing of Ransomware
    Topics

  • Overview

    This final course section will serve as a real-world challenge for students by requiring them to work in teams, use the skills they have learned throughout the course, think outside the box, and solve a range of problems from simple to complex. A web server scoring system and Capture-the-Flag engine will be provided to score students as they submit flags to score points. More difficult challenges will be worth more points. In this defensive exercise, challenges include packet analysis, malware analysis, and other challenges related to the course material.

Prerequisites

While not required, it is recommended that students take SANS's SEC401: Security Essentials: Network, Endpoint, and Cloud course or have the skills taught in that class.

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 not be able to fully participate in hands-on exercises in your course. Therefore, please arrive with a system meeting all of the specified requirements.

Back up your system before class. Better yet, use a system without any sensitive/critical data. SANS is not responsible for your system or data.

MANDATORY SEC501 SYSTEM HARDWARE REQUIREMENTS
  • CPU: 64-bit Intel i5/i7 (8th generation or newer), or AMD equivalent. A x64 bit, 2.0+ GHz or newer processor is mandatory for this class.
  • CRITICAL: Apple systems using the M1/M2 processor line cannot perform the necessary virtualization functionality and therefore cannot in any way be used for this course.
  • BIOS settings must be set to enable virtualization technology, such as "Intel-VTx" or "AMD-V" extensions. Be absolutely certain you can access your BIOS if it is password protected, in case changes are necessary.
  • 16GB of RAM or more is required.
  • 125GB of free storage space or more is required.
  • At least one available USB 3.0 Type-A port. A Type-C to Type-A adapter may be necessary for newer laptops. Some endpoint protection software prevents the use of USB devices, so test your system with a USB drive before class.
  • Wireless networking (802.11 standard) is required. There is no wired Internet access in the classroom.
MANDATORY SEC501 HOST CONFIGURATION AND SOFTWARE REQUIREMENTS
  • Your host operating system must be the latest version of Windows 10, Windows 11, or macOS 10.15.x or newer.
  • Fully update your host operating system prior to the class to ensure you have the right drivers and patches installed.
  • Linux hosts are not supported in the classroom due to their numerous variations. If you choose to use Linux as your host, you are solely responsible for configuring it to work with the course materials and/or VMs.
  • Local Administrator Access is required. (Yes, this is absolutely required. Don't let your IT team tell you otherwise.) If your company will not permit this access for the duration of the course, then you should make arrangements to bring a different laptop.
  • You should ensure that antivirus or endpoint protection software is disabled, fully removed, or that you have the administrative privileges to do so. Many of our courses require full administrative access to the operating system and these products can prevent you from accomplishing the labs.
  • Any filtering of egress traffic may prevent accomplishing the labs in the course. Firewalls should be disabled or you must have the administrative privileges to disable them.
  • Download and install VMware Workstation Pro 16.2.X+ (for Windows 10 hosts), VMware Workstation Pro 17.0.0+ (for Windows 11 hosts), or VMWare Fusion Pro 12.2+ (for macOS hosts) prior to the start of the class. If you do not own a licensed copy of VMware Workstation Pro or VMware Fusion Pro, 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 on its website. This course requires a "Pro" version of VMware software. The "Player" versions are not sufficient.
  • On Windows hosts, VMware products might not coexist with the Hyper-V hypervisor. For the best experience, ensure that VMware can boot a virtual machine. This may require disabling Hyper-V. Instructions for disabling Hyper-V, Device Guard, and Credential Guard are contained in the setup documentation that accompanies your course materials.
  • Download and install 7-Zip (for Windows Hosts) or Keka (for macOS hosts). These tools are also included in your downloaded course materials.

Your course media are delivered via download. The media files for class can be large. Many are in the 40-50GB range, with some over 100GB. 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 soon as you get the link. You will need your course media immediately on the first day of class. Do not wait until the night before class to start downloading these files.

Your course materials include a "Setup Instructions" document that details important steps you must take before you travel to a live class event or start an online class. It may take 30 minutes or more to complete these instructions.

Your class uses an electronic workbook for its lab instructions. In this new environment, a second monitor and/or a tablet device can be useful for keeping class materials visible while you are working on course labs.

If you have additional questions about the laptop specifications, please contact laptop_prep@sans.org

Author Statement

"My introduction to cybersecurity began in the early 1990s as a neuroscience Ph.D. student on the day after our lab was the victim of a cyber attack. That's when I discovered that our UNIX workstations had known vulnerabilities for which patches had to be downloaded and installed. Entirely self-taught, I learned to patch and rebuild kernels and compile, deploy, configure, and use tools like Tripwire, SATAN, and TCP Wrappers. Later, as a full-time enterprise administrator, I learned about switches, routers, and firewalls; RSA SecurID, IPSec VPN, and proxy gateways; hardening Windows endpoints; automating the auditing of Active Directory and the dynamic population of security groups; administering Nexpose; and wrangling IPTables. My own multifaceted technology background makes me particularly enthusiastic about being the lead author for SEC501. The course reflects my own experience as a jack of all trades and provides the perfect opportunity to share that excitement with you!"
