Exchange Online – Attachment handling in Outlook on the web

Exchange Online August 29, 2021 Leave a comment

Customers who completely prohibit access to webmail may have a few security concerns. In a Modern Workplace scenario, all users must be able to access their email at any time and from any location. One of the major improvements we have seen from Outlook web access and now Outlook on the web which gives all the rich client end user experiences we see on the Outlook client. However, attachments can pose a significant security concern if Outlook on the web is permitted to be accessed from non-managed machines without any security implementation or if no data loss prevention mechanism in place.

There are two options to handle this scenario at this moment and we will go through them on this blog.

Use Organizational Config ,Mailbox Policy & ADFS claim rules Method :

We can use mailbox policy settings to define whether users can open, view, send, or receive attachments when they are signed into Outlook on the web, including whether the user is on a computer that is part of a private or public network.

We have the PublicComputersDetectionEnabled organization value which can help us to prevent downloading the attachments from the non managed computers. The PublicComputersDetectionEnabled parameter determines whether Outlook on the web detects whether a user logs in from a public or private computer or network, and subsequently applies the public network’s attachment handling settings. $false is the default value. If you set this option to $true, however, Outlook on the web will detect if the user is logging in from a public computer, all attachment handling rules will be applied and enforced.

We can check that by running the below command.

Now we run the below command and enable the PublicComputersDetectionEnabled value to True

Microsoft Teams – Enable content camera for your meeting rooms whiteboard

Meeting Rooms, Microsoft Teams August 4, 2021 Leave a comment

A content camera can be used with a Microsoft Teams Room system. A content camera collaborates with image-processing software and a whiteboard to enable a presenter to draw on an analog whiteboard and share the content with remote participants.

In this blog we will run through the steps to enable content camera on Teams Room Systems.

There are few prerequisites that needs to be prepared before trying this setup:

  1. This content camera should be pointed at the room’s whiteboard. Please keep in mind that content camera has physical infrastructure requirements that must be considered. It’s usually a piece of equipment (a supported content camera) that hangs from the ceiling and faces the whiteboard.
  2. The writing board must be mandatorily white in color. Other colors are not supported.
  3. A supported content camera as per Microsoft Recommendation on this link needs to be used mandatorily for this functionality.

The camera’s positioning is influenced by the size of the whiteboard used for sharing. The following are some suggestions for board size from Microsoft:

  • 3–6 ft. (0.9–1.8 m) wide — Supported best suited for medium sized rooms.
  • 6–9 ft. (1.8–2.7 m) wide — Recommended best recommended for medium-large rooms.
  • 9–12 ft. (2.7–3.6 m) wide — Supported suitable for board rooms.
  • Above 12 ft. (3.6 m) wide — camera covers 9–12 ft. (2.7–3.6 m) and crops the rest.

The camera can be placed up to 6 in. (152 mm) above the whiteboard’s top and centered on the whiteboard.

Meeting Rooms, Microsoft Teams, Office 365 June 21, 2021 Leave a comment

In the current scenario most of the Organizations are running Teams Room systems as their meeting room solution from their Offices. Few of their customers, vendors and partners host their meetings from Zoom ,WebEx or other meeting solutions. In these unique circumstances, we will be hitting in a scenario where there are people attending the meetings from Teams Room from our organization and the meeting sent by vendor or a customer might be Web-Ex or Zoom.

Knowing this requirement Microsoft released a supported Teams App version in the mid of last year for the Room Systems to join Cisco WebEx Meetings from a Teams enabled room system with the direct guest join. Later this option was extended to attend a Zoom Meetings as well from the Teams App version 4.6.20.0. We’ll walk through the procedures to enable Teams Room Devices to join the 3rd party meetings Cisco WebEx and Zoom Meetings.

There are few prerequisites to be met in order to join WebEx and Zoom Meetings from a Teams Room System

  1. Make sure the WebEx and the Zoom Meeting URLs are fully whitelisted in your proxy and in your network to fully support this scenario.
  2. Configure Office 365 Threat Protection and Link Rewrite exclusion list for WebEx and Zoom Meeting URLs.
  3. Configure your Room Mailbox to automatically accept and process the invitation from Zoom and WebEx.
  4. Configure this settings in your Room Systems devices , so that they are ready for this functionality.

To make this work for the Room Mailbox Connect to your Office 365 Exchange Online Tenant and check for the current setup for accepting the meeting room from a 3rd party meeting invites by running the below command.

Get-CalendarProcesing -Identity UserPrincipalNameOfRoomMailbox | Fl Identity,ProcessExternalMeetingMessages

In our case the value is set to false which is by default. The ProcessExternalMeetingMessages parameter specifies whether to process meeting requests that originate outside the Exchange organization.

Run this command on the Room Mailbox of the Room System to accept meeting requests from Zoom and WebEx

Set-CalendarProcessing roomnl@ezcloudinfo.com -ProcessExternalMeetingMessages $True -DeleteComments $False -DeleteSubject $False

Now we could see that the value ProcessExternalMeetingMessages is set to True

Enable Modern Authentication on Microsoft Teams Room Devices

Microsoft Teams, Modern Authentication, Security May 23, 2021 Leave a comment

As we all know the basic authentication will be retired for Office 365 sooner and its high time for us to enforce Modern Authentication on all clients. When most of the organizations have already enabled Modern Authentication which is a good sign. However there are cases where the modern authentication cannot be interactive for the 2nd factor authentication ,needs some planning on those special cases and they have exceptions. For instance Room Systems they are having resource accounts with Teams Enabled and Exchange Online where these resource accounts cannot have modern authentication enabled with MFA like normal user accounts to approve for the 2nd factor authentication.

Post Microsoft Teams Room App version 4.4.25.0 we have the option to enable Modern Authentication on the devices capable of hosting Microsoft Teams Meeting. The account management of the Teams Room devices is set at the application level.

Microsoft Teams – Configure your Surface Pro device as your personal meeting room

Meeting Rooms, Surface Pro April 22, 2021 Comments: 4

As we all are working remotely from home ,Microsoft Teams has been an extraordinary assistance for all of us in boosting our productivity and keeping us stay connected in this pandemic situation. We are in Teams Remote meeting for almost everyday to complete our daily chores. Well the vast majority of individuals are having a office setup scenario at this point, however its less likely we have setup our own personal meeting room equipment . Most likely we are attending the meetings and doing the works from the same device.

This wasn’t the case before but since we are almost having very frequent remote meetings every day its a good idea to have one personal meeting room device for the below reasons :

  1. You have your laptop with multiple excel sheets, Word Documents , PDFs, Browsers etc., always and you do not need to switch between camera screen and your work thats going on.
  2. There are 2 screens where one is fully focused only for work and other is dedicated only for Meetings.

There are loads of items in the market which is available in a competitive pricing , yet my thought in this blog is to demonstrate that we have a very good option to convert Windows compatible tablet or a Surface Pro into a personal meeting room just in case if you have additional device which has been hibernated for quite a long time.

Microsoft Teams – Apply Sensitivity Labels to secure content in Microsoft Teams

Microsoft Information Protection, Office 365 April 5, 2021 Leave a comment

Classification of data is always an important factor for any organization to protect their data and to make sure only the right people have the access to the right documents. Couple of years back we went through the Azure Information Protection on this blog through which we can classify the sensitivity of any organization documents and leverage them on the Microsoft 365 Applications. Previously in Microsoft 365 only had the built in retention labels through which only the classification of the documents was possible. During this time in order to apply more protection like auto classification and enforce the policy the Azure information Classic Client and Azure Information Protection was utilized.

Its very important to note at this point that the Azure Information Protection Classic client and the Label Management from the Azure Portal are deprecated from March 31 2021.

It has been a quite long time that Microsoft supports sensitivity labels in addition to retention labels, so all action can be completed from the same location from Microsoft Information protection in the Compliance Center. Microsoft recommends to utilize to new Unified labeling and upgrade the clients to new unified labeling client.

Cloud DLP and Regulatory Compliance: 3 Things You Must Know

DLP, Security March 15, 2021 Leave a comment

This article was originally published at nightfall.ai

It’s well-established that a data breach is an extremely costly event. By some estimates, a data leak can cost a small to medium-sized business more than $7.68 million per incident.

Compliance regimes may seem burdensome, but the goal of these policies is to prevent a devastating data breach that can bankrupt a business and cause myriad problems for consumers. It’s important to understand the differences between compliance and security, as well as how data loss prevention (DLP) allows your organization to accomplish both objectives efficiently and affordably.

Here’s what you need to know about cloud DLP and prevalent compliance policies like HIPAA, GDPR, and others.

Cloud compliance vs. cloud security: what’s the difference?

Cloud compliance and cloud security overlap, but these are two different areas of practice. Cloud compliance refers to the regulations and policies designed to protect individuals and companies from the impact of data loss. More specifically, compliance focuses on the type of data collected and stored by a business, as well as the regulatory frameworks that apply to data protection. Cloud security is made up of the physical tools and platforms that protect and defend customer and company data. This could include software like VPNs, DLP platforms like Nightfall, and tools like multifactor authentication. Cloud security also requires action-oriented cloud security policies that are updated regularly to reflect changes in the business and new online threats

Over here we are not going to deep dive much into Telnyx configuration since our task is to create a PSTN Trunk between them and our SBC. So we will go through only the steps that is required to complete the Direct Routing Configuration.

The moment when we subscribe with Telnyx they provide an advance credit of 10 USD and a portal like below. As per the Telnyx documentation we need to create a new SIP connection to our SBC in the below section where we could see they have a SIP connection with their backend system as a default setup.
