User: tsonger

Instructor comments: While I could tell the instructor was very knowledgeable, his instructions were not very clear. He could've done a better job preparing for the class.

Facilities comments: Room was fine. The location of the room could have been better as the dings from the elevator were a bit distractive.

User: TracyPaul

Instructor comments: Very knowledgeable. Diagnosed our programming problems in short order. Could go into the details of 'why', versus only the 'how'.

Facilities comments: Outstanding. The hotel staff did a great job supporting our class.

TN-965 Windows Security Automation with Powershell

Course Overview:

PowerShell is made for Security Operations (SecOps) automation on Windows. SecOps requires automation in order to scale out security changes and monitoring beyond a handful of hosts. For example, when a vulnerability must be remediated but there is no patch for it yet, automation is needed to quickly and consistently enact the changes necessary. PowerShell “remoting” is encrypted remote command execution of PowerShell scripts in a way that can scale to thousands of endpoints and servers.

Imagine being able to hunt for indicators of compromise across thousands of machines with just a few lines of PowerShell code. Or imagine having the local Administrator account password reset every night on thousands of endpoints in a secure way, and being able to retrieve that password securely too.

We will show you to do these tasks and more. Transcription logging for forensics, strong encryption code signing, application whitelisting of scripts, IPSec port control, and Just Enough Admin (JEA).

As more and more of our systems are moved up to the cloud, PowerShell will become even more important. Amazon Web Services, Microsoft Azure, Office 365, Hyper-V and VMware already support PowerShell administration for many tasks.

Attendees to TN-965: Windows Security Automation with PowerShell will receive TechNow approved course materials and expert instruction.
