Description

After you create a custom sensitive information type that specifies the identity (GUID value) of the DLP keyword dictionary, the dictionary will appear in your list of sensitive information types, and you can use it in policies.

To use this cmdlet in Security & Compliance PowerShell, you need to be assigned permissions. For more information, see Permissions in the Microsoft Purview compliance portal.

Examples

Example 1

$Keywords = @("Aarskog's syndrome","Abandonment","Abasia","Abderhalden-Kaufmann-Lignac","Abdominalgia","Abduction contracture","Abetalipo proteinemia","Abiotrophy","Ablatio","ablation","Ablepharia","Abocclusion","Abolition","Aborter","Abortion","Abortus","Aboulomania","Abrami's disease","Abramo")

$EncodedKeywords = $Keywords | ForEach-Object {[System.Text.Encoding]::Unicode.GetBytes($_+"`r`n")}

New-DlpKeywordDictionary -Name "Diseases" -Description "Names of diseases and injuries from ICD-10-CM lexicon" -FileData $EncodedKeywords

This example creates a DLP keyword dictionary named Diseases by using the specified values.

Example 2

$Keywords = Get-Content "C:\My Documents\InappropriateTerms.txt"

$EncodedKeywords = $Keywords | ForEach-Object {[System.Text.Encoding]::Unicode.GetBytes($_+"`r`n")}

New-DlpKeywordDictionary -Name "Inappropriate Language" -Description "Unprofessional and inappropriate terminology" -FileData $EncodedKeywords

This example creates a DLP keyword dictionary named Inappropriate Language from the file C:\My Documents\InappropriateTerms.txt. The file contains one term on each line.

Parameters

-Confirm

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.
