Automated Investigation & Response

The Automated Investigation & Response feature under Threat management in Security & Compliance admin portal is a pritty new and amazing feature in Office 365.

To use this feature you need to have “Office 365 Advanced Threat Protection Plan 2” licenses witch you can purchase standalone or it`s included in the Office 365 E5 license and yes – you need to be a “Global Administrator” or “Security Administrator” to configure the service. Once configured you can also use “Security Reader” or “Security Operator” to see whats happening.

Have a look here to see all capabilities within “Advanced threat protections”.

So over to Automated Investigation & Response (AIR) – have a look at this screenshot

As we see her we have two detection on-going which waiting on user action. The first one in the picture is automatically found by the system and the second one is a email which I reported through the “Message Report” add-in for Outlook which are deployed to all users (Both Outlook and Outlook Web).

In the overview of the case (the one i reported) we see what`s going on with the message, the Trigger alert, what threats  who where found, how many emails are “infected” and which users that have the infected email in their mailbox (could be a mass-phishing attack)

When we navigate to the Email tab we see what section of the email that are found malicious and in this case the Advanced Threat Protection has matched the URL to a malicious URL

Moving to the Action tab – we are given several a big tool belt meaning that we can do a soft delete from the users mailboxes (in this case only one user, but if this malicious email was delivered to 100 users we can in one click remove the email from the users mailboxes) and block the URL in Safe Links.

So this was very short on how to easily use AIR in your tenant if you have the right license.

Get started with MFA – part one

You problably heard about multifactor authentication by now, but have you enabled it in your environment?  

If not! Please do so at once! I will in this short blogpost give you the direction to get started with MFA in Azure AD. 

So let`s just jump right into it.  

First things first – protect your admin accounts!  

With admin accounts i mean a account who has a additional role assigned other then beeing a regular user and to mitigate these users we will enable a Conditional Access who is requires MFA for all administrator accounts 

So navigate to Azure Active Directory in portal.azure.com 

Dive into “Security” -> “Conditional Access”  

Click the “Baseline policy: Require MFA for Admins (Preview) and choose to use it immidiatly 

So now you have successfully enabled MFA for all your admins! Great work 😊 

To make it easier for yourself you can now change the MFA verification from the default SMS to Authenticator app by visiting https://aka.ms/mfasetup and add the Authenticator app as a preffered method. 

Next up is to enable it for all your users and that i will cover in the next blog post – Stay tuned for “Get started with MFA – Part two” 🙂

Reset folder language to match Outlook Web Access language

So in the recent time i have been working with a customer to integrate Exchange Online mailboxes into a customer support application witch are using POP. The application throwed a error message:

02:47:34.513 Trc 21628 [MsgIn-2] <pop-client1> Mailbox account 'yourmailbox@domain.no'[https://outlook.office365.com/EWS/Exchange.asmx:443]: opening mail folder 'INBOX'
02:47:34.748 Std 21627 [MsgIn-2] <pop-client1> No INBOX Folder found on Corporate Email Server

This indicates that the software witch is polling emails need the inbox folder to be “Inbox” and not “innboks” (witch is Inbox in norwegian). So we need to change the default folders to match the language set in OWA.

  1. Logon to your account on outlook.office.com
  2. Head into to the Gear icon next to your profile picture in the top-right corner and in the bottom select: Your app settings-> Mail

3. Select General in the left pane and then click on: Region and timezone.

4. In language, set your language for OWA and check the checkbox witch also renames the default folders to match the selected language and hit the save button.
