DLP for Bitcoin Addresses

One of the up-and-coming combination phish-ransom attacks is to trick the mark into thinking that you’ve got access to their data, and then get them to send money to a Bitcoin address to protect them from data leakage.  You can create a DLP rule in the Office 365 Security & Compliance Center (or an Exchange Online transport rule) to try to combat this.… [ Continue reading ]

Alerting on OneDrive Deleted Item Activity

I had a customer recently raise some questions about how to provide further enhancements and protections around their OneDrive for Business deployments.  Suppose this scenario exists:

  • Users are site collection administrators over their OneDrive for Business sites (default configuration)
  • Retention policies are configured, but may only be configured to provide a very minimal amount of data protection (such as 90 days from creation or last modification of data) due to organizational legal compliance
  • No retention policies are in effect for the target data (as all the data we’re concerned with is technically older than 90 day creation or last modified date)
  • Malicious or disgruntled user deletes OneDrive data
    • Deletes data in OneDrive
    • Empties recycle bin
    • Empties second stage recycle bin

At this point, for any data older than 90 days, it is lost.… [ 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 to the Get-UserHoldPolicies tool

While working with a customer last week, it came to my attention that the Get-UserHoldPolicies script I had put together to enumerate retention policies and eDiscovery cases that put a hold on content wasn’t displaying policies that were global.  The types of policies I checked for were enumerated in a user’s InPlaceHolds mailbox property, but apparently, that field is populated only if a Security & Compliance retention policy explicitly specifies the mailbox.… [ Continue reading ]

Creating and Managing Security and Compliance Filters in the Real World [Part 2]

Picking up where I left off on part 1 of this post, I wanted go into what it would take to refine some roles for managing eDiscovery for larger organizations.

In this scenario, we’re going to:

  • Remove users from any existing eDiscovery roles or groups
  • Create a security group to hold users that will perform eDiscovery searches
  • Create a custom role group that has the appropriate eDiscovery roles and add the security group as a member
  • Verify

If you didn’t read the previous blog post on this topic, I’d encourage you to go back and do so, since I’m going to continue using the same users and compliance filters.… [ Continue reading ]
