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 two

So in the previously post I went through how to activate MFA for Administrator roles i a really simple and effective way.

In this post we will focus on activating MFA for all regular users. And first off all we need to evaluate who should be activated first or should we activate on all users at the same time and do a evaluation on service accounts! If we enable MFA on for example a serivce account used for scan to email on “multi functional printers” or on a mailbox account witch are used on a thirdparty ticketingsystem (POP/IMAP) we could break those service by just enabling MFA on all users.

My recomandation is when you are more then 30 users in your company you should select a few ambasadeurs who is getting the MFA activated first and can therefore be the power users who can help others with the registration if there is any hick-ups (should not be many).

And to activate MFA for end users I highly recomend to use Conditional Access for

  • all users and exclude a AzureAD Group which contains a “Break the glass Admin” and other service accounts.
  • All cloud apps (no exeptions)
  • Grant Access – but require MFA

Easy like that! And It`s a realy quick solution for your company.

Drawback here is that you need “Azure AD Premium P1” licenses to use Conditional Access and a second drawback is that it`s not scored at the Microsoft Secure Score.

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” 🙂
