Fixing Office 365 Anonymous Group Write-back and External Delivery

Yes, Hell has frozen over. The cows have come home. The lady of size has sung.

For the long(er) background, you’ll probably want to go see this post.… [ Continue reading ]

Creating Scoped DLP rules with Custom Sensitive Information Types

A few weeks ago, I put out a series of posts on creating and using custom sensitive information types (https://bhr.62e.myftpupload.com/tag/sensitive-information-types/).  The blog, posts, however, focus on using the DLP configuration options available in the Security & Compliance Center.

Rules created via the DLP wizard in the Security & Compliance Center have the benefit of being able to be applied globally across your organization and its content sources. … [ Continue reading ]

Looky, looky! Custom sensitive information types with even more customitivity!

So, of course, as soon as I finish up posting a few entries (here and here), we go and release a new UI to help you get it done on your own!

You can do most of the effort of creating a data classification here, although if you want to use any of our built in functions (such as credit card Luhn check), you’ll need to export/modify/import, use the sensitive information type package that I created (referenced earlier) or use one of our native DLP classifications.… [ Continue reading ]

Sensitive Information Types–now with more sensitivity!

UPDATE: The file link for this post has been updated.

So, this is an entry that has been long in the making.  I have had several customers over the last few years give feedback about our Data Loss Prevention’s (DLP) matching requirements, mostly around how they require too much corroborating evidence (in the form of patterns or keywords) to meet their organization’s very restrictive policies.… [ Continue reading ]

Update: AAD Connect Network Test Tool

I trotted out the trusty WireShark and Fiddler tools today and ran through the latest iteration of AAD Connect setup.  In so doing, I’ve added a few endpoints to the test:

Testing a variable with the value of zero

Tonight, while working on my previous script, I ran into an interesting problem when testing the presence of a value.

Consider this:

PS C:\> [int]$IntValue0 = 0
PS C:\> [int]$IntValue1 = 1
PS C:\> [string]$StringValue0 = "0"
PS C:\> [string]$StringValue1 = "1"
PS C:\> $IntValue0
0
PS C:\> $IntValue1
1
PS C:\> If ($IntValue0) { "exists" }
PS C:\> If ($IntValue1) { "exists" }
exists
PS C:\> if ($StringValue0) { "exists" }
exists
PS C:\> if ($StringValue1) { "exists" }
exists
PS C:\> if ($IntValue0 -eq $null) { "null" }
PS C:\> if ($IntValue0 -lt 1) {"less than 1" }
less than 1
PS C:\> $IntValue0.GetType()
