Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Blocking files with file extensions such as .exe, .hta, .js, or .iso is a good start.”

A block of code is set as follows:

    "policyRule": {
      "if": {
        "allOf": [
          {
            "field": "location",
            "notIn": "norwayeast
          },
          {
            "field": "location",
            "notEquals": "global"
          },
        ]
      },
      "then": {
        "effect": "deny"

Any command-line input or output is written as follows:

$varHours = 72
Get-GPO -All | Where {((Get-Date)-[datetime]$_.ModificationTime).Hours -lt $varHours}

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “In the configuration portal, go to Customization | Policy Management, and then click Create to start the wizard.”
