Course Description

Hackers know how to use PowerShell for evil. Do you know how to use it for good? In SEC505 you will learn how to use PowerShell to automate Windows security management across an Active Directory enterprise.

DON'T JUST LEARN POWERSHELL SYNTAX, LEARN HOW TO LEVERAGE POWERSHELL AS A PLATFORM FOR SECURITY.

You've run a vulnerability scanner and applied patches - now what? A major theme of this course is defensible architecture: we have to assume that there will be a breach, so we need to build in damage control from the beginning. Whack-a-mole incident response cannot be our only defensive strategy - we'll never win, and we'll never get ahead of the game. By the time your monitoring system tells you a Domain Admin account has been compromised, IT'S TOO LATE. We need to prevent pass-the-hash attacks and Kerberos Golden Ticket attacks as much as possible, not just detect them.

Perhaps you've taken a hacking course at SANS and now you want to learn more Windows and Active Directory attack mitigations: SEC505 is that course.

Learning PowerShell is also useful for another kind of security: job security. Employers are looking for people with these skills. You don't have to know any PowerShell to attend the course, we will learn it together. About half the labs during the week are PowerShell, while the rest use graphical security tools. Many of the PowerShell scripts written by the course author are free in GitHub (just go to http://SEC505.com).

If you are an IT manager or CIO, the aim for this course is to have it pay for itself 10 times over within two years, because automation isn't just good for security, it can save money too.

SEC505 IS DESIGNED FOR THE BLUE TEAM TO BLOCK THE ATTACKS OF THE RED TEAM.

The focus of this course is on how to automate the NSA Top 10 Mitigations, the CIS Critical Security Controls related to Windows, and the MITRE ATT&CK mitigations for Windows, especially the ones that are the difficult to implement in large environments.

SEC505 will also prepare you for the GIAC Certified Windows Security Administrator (GCWN) certification exam to prove your Windows security expertise. The GCWN certification counts towards a Master's Degree in Information Security from the SANS Technology Institute (www.sans.edu) and satisfies the Department of Defense 8140 computing environment requirement. The GCWN is also a foundational certification for soldiers in the U.S. Army's 255-S Information Protection Program. For DoD students, we will see how to apply the NSA/DISA Secure Host Baseline.

This is a fun course and a real eye-opener, even for Windows administrators with years of experience. We don't cover patch management, share permissions, or other such basics - the aim is to go far beyond that. Come have fun learning PowerShell and Windows security at the same time!

Learning Objectives

  • Configure mitigations against attacks such as pass-the-hash, Kerberos golden tickets, Remote Desktop Protocol (RDP) man-in-the-middle, Security Access Token abuse, and other attacks discussed in SEC504 and other SANS hacking courses.
  • Execute PowerShell commands on remote systems and begin to write your own PowerShell scripts.
  • Harden PowerShell itself against abuse, and enable transcription logging for your SIEM.
  • Use Group Policy and PowerShell to grant administrative privileges in a way that reduces the harm if an attack succeeds (assume breach).
  • Block hacker lateral movement and malware Command & Control channels using Windows Defender Firewall, IPsec, DNS sinkholes, admin credential protections, and more.
  • Prevent exploitation using AppLocker and other Windows OS hardening techniques in a scalable way with PowerShell.
  • Configure PowerShell remoting to use Just Enough Admin (JEA) policies to create a Windows version of Linux sudo and setuid root.
  • Install and manage a full Windows Public Key Infrastructure (PKI), including smart cards, certificate auto-enrollment, Online Certificate Status Protocol (OCSP) web responders, and detection of spoofed root Certification Authorities (CAs).
  • Harden must-have protocols against exploitation, such as SSL/TLS, RDP, DNS, DNSSEC, PowerShell Remoting, and SMB.
  • Use PowerShell to access the WMI service for remote command execution, searching event logs, reconnaissance, and more.
