Episode 274 – PowerScripting Podcast – Microsoft Distinguished Engineer Jeffrey Snover on JEA

A Podcast about Windows PowerShell. Listen:

In This Episode

Tonight on the PowerScripting Podcast, we talk to Distinguished Engineer Jeffrey Snover



Guest – Jeffrey Snover



  • JEA premises
    • reduce the # of admin privs users
    • credentials persist and can be used to spider
    • limit actions
  • New toolkit based on powershell remoting
  • JEA endpoint = powershell configuration
    • provisions user w/set of toolkits (and only those)
    • runs as an account with local admin privs
    • JEA endpoint account has only local admin privs
  • “security that isn’t deployed, isn’t security”
  • How can we take advanced features and reduce to a simple set of features to deploy
  • Implemented as DSC
  • PowerShell v5 is required
    • Why: any time that WinRM changes are made, WinRM service must be restarted, and v4 has a bug in WinRM
  • Very similar to sudo from *nix, but more fine-grained, e.g. limit which process can be stopped by stop-process
  • Build CSV as input to a toolkit spec
    • module
    • command(s)
    • parameters
  • Logging is sent to ETW/PowerShell, and is broken down by module
  • Will ship as a set of toolkits
  • OMI runs on 41 Linux distros
  • “CTP next month” (meaning July?)
  • “yes, moving back towards developers and new .net features”

Chatroom Highlights:

[21:37:02] <sepeck> ## when is the next one [MVA]?

[21:38:07] <AlexTeachesTech> ## Will there be a DSC video series on MVA?

[21:45:05] <Ver_Anderson> ## What kind f pats do yu wear

[21:45:15] <psCookieMonster> just to get it out of the way – ## are classes coming to PS5, anything to share on the implementation?  Is a new PowerShell MVA on the way, what might be covered?  when will we get the PowerShell source code? : )  Maybe too early for the last one!

[21:45:18] <jcotton> ## is JEA based on PowerShell remoting?

[21:48:48] <BartekB> ## DSC for Linux is based on OMI. Can we expect easy OMI-to-DSC implementations? Like DSC for Cisco/ Arista/ Huawei?

[21:49:05] <MattHitchcock> ## Whats the approach for using JEA on Domain Controllers? I guess you’d be forced to use a Domain Account for RunAs

[21:51:17] <Zackbmiller> ## Can JEA be ran on all version of powershell?

[21:58:43] <BartekB> ## Why New-Object in JEA?

[21:59:26] <BartekB> halr9000: When I was watching Jeffrey presentation: he defined (exposed) new-object in endpoint.

[21:59:11] <PowerSchill> ## How do you handle the “chain of evidence” for the actions performed?

[22:03:18] <DonJ-MVP> ##### Payette “outed” classes in v5 on Twitter yesterday. Inquiring minds wanna confirmation.

[22:13:54] <psCookieMonster> ## will the slides from the Monad Manifesto update be made available?  Might be helpful for those that missed it

[22:18:24] <Darkoperator> wish OMI was packaged and available in most distros

[22:20:17] <randal_hicks> ## @jsnover With a project as huge as Powershell, how have you gone about managing it (other than check marks off the Monad Manifesto)?

[22:22:11] <randal_hicks> ## @jsnover How do you ‘unplug’ — to clear your head — before diving back into the work?

[22:42:26] <psCookieMonster> ## Jeffrey tweeted about DSC being fast tracked for the common engineering criteria a while back… in what sense?  standard for configuration management? Something else?

[22:44:23] <_____> “How I learned to stop clicking and love the shell” Jeffrey Snover

[22:47:50] <BartekB> ## why not xResources on GitHub, so that others can jump on it and help? We had some fixes to cResources and than almost the same on xResource.

<Ver_Anderson> @sepek I was looking at this one http://www.ncix.com/detail/cooler-ma…85648-1141.htm

<brwilkinson> did anyone see this article last month: http://blog.opslogix.com/?p=203

<sepeck> any chance of a DSC getting added to the TLGs?   http://social.technet.microsoft.com/wiki/contents/articles/1262.test-lab-guides.aspx

<psCookieMonster> AlexTeachesTech – presumably a subset or superset of something like https://automatedlab.codeplex.com/ could be handled by DSC
