Using Microsoft 365 to secure information


Here’s a presentation I did recently on security using Microsoft 365 Business. You can download the slides here:

Free CIAOPS Yammer support network

image

I am happy to announce that I have set up a free CIAOPS Patron support network on Yammer that is focused on the Microsoft Cloud. In there I have groups on Azure, Microsoft 365, Office 365, Windows 10 and more. Members can ask questions, reply to posts as well as a share interesting information to help others.

Although access to this network is free it is by invite only, so if you want access you’ll need to send me an email (director@ciaops.com) requesting access.

I’ve done this in Yammer for a few reasons. Firstly, it is going to give me the experience of managing a ‘larger’ Yammer external network. This will hopefully improve both my technical experience with the product but also skill me more on how to successfully implement adoption. Secondly, I’ve hopefully giving people a way to get a feel for what Yammer is all about, how it works and what benefits it provides. Yammer for me is probably the most important adoption tool as I have said before:

Focus on the “me” services first

so hopefully giving people a reason to come and experience Yammer for themselves will give them a better idea of what role it can play in a business.

Again, this offering is free but by invite only. To secure your invite just email me at director@ciaops.com.

Configuring an Office 365 SPAM filtering policy

A common complaint I hear about Office 365 from IT Professionals is that it doesn’t filter spam as well as other third party solutions. My immediate question at that point is always “Well, have you actually gone in and configured ANY of the spam settings in Office 365 to improve your results?” to which the answer is always No. Thus, if you don’t take the time to customise what you get out of the box you’ll only get an out of the box solution which is probably not what you want! Thus, some configuration is required for EVERY Office 365 tenant to improve its spam filtering abilities.

The out of the box spam settings for Office 365 are not configured in an aggressive manner and you should go in and make changes from the defaults I would suggest. Here’s how to do that.

image

You’ll firstly need to login to the Office 365 portal as an administrator with rights to make changes. You’ll need to then navigate to the Office 365 Admin Center and select from the Admin centers on menu on the left hand side. You’ll find the Admin centers option right at the bottom.

From the list of options that now appear select Exchange as shown above.

image

This will take you to the Exchange Admin center as shown above. In here select the protection option on the left and then spam filter on the right.

You will then typically see a single policy called Default.

image

With this default policy selected, press the edit button (pencil) from the menu to view what settings this default policy has.

SNAGHTML58800d3

Select the different menu options on the left to view all the settings. Most you will see, like in the advanced settings shown above, are set to off.

You can of course edit this default policy, however it is better practice to go back to the list of policies and create a new one and leave the default one in place.

image

When you create a new policy using the plus button (+) a new dialog will appear like show above.

Give the new policy a name and now scroll through the settings to configure them for your needs.

image

image

When you reach the advanced options towards the bottom you’ll see a number of options that can set on or off. The crowd sourced results I obtained for these were:

Image links to remote sites = OFF

Numeric IP addresses = ON

URL redirect to other port = ON

URL to .biz or .info websites = ON

Empty messages = ON

Javascript or VBScript in HTML = ON

Frame or iFrame tags in HTML = ON

Object tags in HTML = ON

Embed tags in HTML = ON

Form tags in HTML = ON

Web bugs in HTML = ON

Apply sensitive word list = ON

SPF record hard fail = ON

Conditional sender ID hard fail = ON

NDR backscatter = ON

image

You can then set whether the policy will simply run in test mode if you wish.

image

The final option is to determine where this policy will apply. Normally you want this across all your domains and users but as you see, you can have different policies for different users and domains if you wish.

All you now need to do is save the policy and start monitoring the results.

Hopefully, you can now see that out of the box Office 365 does take a very relaxed approached to spam which is not uncommon for most spam protection products. You can, and should, of course go in and configure the available options to be more restrictive. When you do this you will of course get much better results.

This post showed you how to make spam filter setting via the web interface, a much better and more consistent approach across many tenants is to do this using PowerShell. Look out for an upcoming article on this.

SPAM filtering in Office 365–Best practice results

Recently, I asked people to vote on the settings in Office 365 Spam protection they believe should be made active to improve protection. That survey will continue to run and you can add your voice here:

http://bit.ly/o365spam

However, with just over 30 votes as I write this I think we can draw some indications of what the best practice options are going to be.

So let’s start with the ones that should be definitely turned on based on a majority of votes for that condition:

URL direction to another port = ON

image

Backscatter = ON

image

SPF Hard fail = ON

image

Scripts in HTML = ON

image

Numeric IP addresses in URL = ON

image

Apply sensitive words list = ON

image

Empty Messages = ON

image

Web Bugs = ON

image

Condition Sender hard fail = ON

image

Form Tags in HTML = ON

image

Frame or iFrame tags in HTML = ON

image

Embed Tags in HTML = ON

image

Next, the one’s that should be off are:

Image links in Remote Site = OFF

image

Lastly, border line results that you probably want to set on if you want aggressive anti spam or off if you want relaxed.

Object tags in HTML = ?

image

URL to .INFO or .BIZ sites = ?

image

I’ll leave the survey running and you can check the results at any time in the future here.

In upcoming post I’ll show you how to set these options inside Office 365. However, thanks to the wisdom of the crowd (thanks to all who voted) we have an idea of what the settings should be.

SPAM filtering Office 365–Help shape a best practice

image

I hear a lot of people say that they don’t find Office 365 anti-spam filtering as good as other providers. My reply to that is – “Have you ever actually gone in and configured the settings from what is there by default?”. Unsurprisingly, the answer is always No.

The out of the box spam settings you get with Office 365 are designed for the “average” and probably configured for the least business interruption (i.e. less aggressive classification of what is spam). Thus, to get the optimal level of filtering you desire, it is recommended that you go and set the options the way that you want.

I have configured my tenant for the way I wish to handle spam but that is probably not exactly the best place for people to start. So with that in mind I thought that I’d call on the power of the crowd and offer up a survey were people can nominate what they consider to be major indicators of spam, based on the policy options that Microsoft provide. You’ll find that survey here:

http://bit.ly/o365spam

which I encourage you to fill out and share with everyone else.

The idea is that once the results are in I report back on an overall “best practices” starting policy that the majority would feel comfortable with. I can then also show you how to exactly configure that in Office 365.

So please take a moment to complete the survey and share you expertise and thought on the ‘best practice’ approach of configure anti-spam policies in Office 365.

You can find the details on the specific advanced spam filtering options in Office 365 here:

Searching the Office 365 activity log for failed logins

image

Inside the Office 365 Security & Compliance center, under the Search & investigation menu option on the left you’ll find Audit log search as shown above.

To run a search simply provide a start and end date and select the Search button at the bottom of the screen. You can refine your search by selecting a list of different activities if you want but here we’ll leave the option set to Show results for all activities.

Once the search results are returned you’ll see lots and lots of items as shown above.

image

If you now select the Filter results button in the top right, each column will now display a box at the top that you can enter text into.

image

You can now go into the column headers and enter further filtering information. Here I have added the text ‘fail’ to the Activity column as shown. This produces two results for failed user logins.

Adding a filter now only shows the matches on the page.

image

You can also export the data into CSV file by selecting the Export results button next to the filter button.

You can either download everything in the audit logs (Download all results) or just your search query (Save loaded results). Here I have select the Save loaded results option.

image

This will then download a CSV file that you can open in Excel and will look like the above.

image

To make these easier to read you should convert the out to a table from the Insert tab and then select the Table icon.

image

Now that you have a table go to the top row of the Operations column and select the arrow to the right of this as shown. This will display the above menu. Uncheck the Select all option at the top of the list in the lower portion of the displayed dialog box.

image

Scroll down this same list and locate the UserLoginFailed option and select it.

This will now basically filter the whole tables of entries to only display those that have a match is UserLoginFailed in the operations column.

image

Which is exactly the result that you see obtained above and the same results we received from the console.

Thus, you can search the audit logs inside Office 365 directly from the portal but you can also export them to Excel to gain more power over how you wish to manipulate and report these events.
