PowerShell Summit Europe 2014 – – Wednesday afternoon

Tobias Weltner started the last part of the Summit with a session on AST – Abstract Syntax Tree - and the PowerShell parser.

You can access the tokens used by the parser for instance to create a variable inventory.

AST takes you beyond the parser tokens and enables to do wonderful things to your scripts such as applying code formatting standards and expanding alias to the full

cmdlet and parameter names.

 

The second session was delivered by Jeff Wouters – Securing Remoting.  How do you secure remoting across the Internet?  How do you authenticate users?

Jeff showed us the issues around credentials and how to manage authentication – especially how to manage passwords.

 

The third session was a Best Practice discussion lead by Don Jones.

Code – If you don’t understand it don’t run it

PowerShell gallery – trusting the code?  Who wrote it? Feedback on code. Code should have ratings.

Module storage – where and why?

What are your thoughts?

 

Jeffrey Snover closed the Summit with a look at Just Enough Admin – RBAC through PowerShell.

Admins are part of the attack surface.

Need to Incrementally reduce admin exposure

JEA controls admin actions through PowerShell constrained endpoints and proxy functions.

JEA toolkit available for download through DSC resource kit

Use DSC for endpoint configuration – makes it simpler and easier

Example – allow access to manage file system but not view contents of files

PowerShell Summit Europe 2014 – Wednesday morning

The last morning started with me covering OMI (WMI) and DSC on Linux. OMI can be set up but wed need more classes; DSC on Linux works in push mode and integrates very nicely with DSC for Windows.

 

The second session consisted of Lee Holmes and Jim Truher introducing the Await module which provides Expect type functionality for PowerShell.

They demonstrated using FTP through ISE; automating Vi and automating SSH.

I can think of lots of uses for this.

 

Final session of the morning was Bartosz Bielawski on dynamic parameters

Dynamic parameters only work in context – the provider context

After demonstrating using dynamic parameters Bartek then showed how to add dynamic parameters to your code – and the hoops you have to go through to get them to work

Quotes from the Summit

Two quotes that stuck in my mind for the future of IT:

 

DSC is last chance for click next admins”

 

If you can just click you’re not a professional

PowerShell Summit Europe – Tuesday afternoon

Mike Pfeiffer kicked off the afternoon talking about DSC in the AWS cloud.  Using DSC to bootstrap new machines and configuration scripts to complete configuration. This works in push mode but pull servers being experimented with.

 

Second session was Jim Truher, a founder member of the PowerShell team, talking about Testing Frameworks.

Testing frameworks are essential.  Pester is a an excellent test framework for Test Driven Development. Pester is extensible as its a script module.

 

Our third session was Mike Marin speaking about PowerShell, devops and Windows Azure.

 

The final session was Lee Holmes - What Goes Bump in the Night? – looking at auditing to see what PowerShell is doing on your system

Security boundaries – once attackers get access to your machine its not your machine. Post exploitation.

Compromising administrators – means need just enough admin – don’t give unfettered access

Event forwarding great for detecting intrusions.

Forwarding occurs over WSMAN

Two days down and more good stuff to come

PowerShell Summit Europe 2015

No not a typo. We, at PowerShell.org, will be repeating the European Summit next year. Location hasn’t been finalised but will be Northern Europe.  The Summit will occur at about the same time of year.  Look to PowerShell.org later in the year for more information. We are hoping to be able to put on a larger event though that has yet to be confirmed.

 

Your support is critical to determining the size of the event, and ensuring the future of the event.

 

Look forward to seeing you next year

PowerShell Summit Europe – Tuesday morning

After a very successful DSC hackathon on Monday evening we reconvened on Tuesday morning with Steve Murawski delivering his second session on DSC.

A brief discussion on devops lead into looking at DSC configurations:

  • Configuration names can’t be hyphenated
  • Circular dependencies are detected
  • Partial named configurations allow multiple configurations working against same machine

The morning’s second session was me talking about creating cmdlets from the CIM StdRegProv class using a CDXML approach.  The talk started with using a single method and demonstrated how to add validation, simplify parameter input by the use of enumerations and how CDXML modules are used within PowerShell.

 

Dan Harman closed the morning session by talking about classes written in PowerShell – this functionality was introduced in the September preview of WMF 5

You can already define a class and load it with Add-Type but you have to write the class in C# or another .NET language. Now you can write the class in PowerShell

Classes can have overloaded constructors and methods.  All class members are public by default.

Enums are possible. Scoping is lexical not dynamic as in PowerShell
