00:00:05

we all share documents with just one click.

00:00:08

Teams,

00:00:08

OneDrive,

00:00:09

Outlook.

00:00:10

Everything is fast,

00:00:11

but this speed can also send a sensitive file to the wrong location

00:00:14

without us even noticing.

00:00:16

Errors happen quickly and quite often without any intention.

00:00:20

An overly broad link,

00:00:21

an unnecessary download,

00:00:23

or sharing in the wrong channel.

00:00:25

Everyday situations that can nonetheless expose sensitive information.

00:00:30

To better control what circulates,

00:00:32

Microsoft 365 relies on multiple layers of protection.

00:00:36

Depending on your organization's license and configuration,

00:00:39

you'll use some or all of them.

00:00:42

The first layer,

00:00:43

permissions.

00:00:44

They control who can open a SharePoint site,

00:00:47

a file in OneDrive,

00:00:48

or a shared document within a team's channel.

00:00:50

That's the foundation.

00:00:52

However,

00:00:52

once a file is downloaded,

00:00:54

these permissions are no longer enough.

00:00:56

The second layer is sensitivity labels.

00:00:58

When they are available,

00:00:59

these labels go much further.

00:01:01

They provide protection for the content itself.

00:01:04

They can encrypt a file,

00:01:05

block its transfer,

00:01:06

and restrict copying,

00:01:08

and this protection follows the file wherever it may go.

00:01:11

Whether it's in Word,

00:01:12

Outlook,

00:01:13

Teams,

00:01:13

OneDrive,

00:01:14

or SharePoint,

00:01:15

it stays protected even if it's transferred or downloaded.

00:01:19

Third layer,

00:01:19

retention.

00:01:20

It manages the content's lifespan.

00:01:23

How long should a file or an email be kept?

00:01:26

When should it be archived?

00:01:28

When should it be automatically deleted?

00:01:30

These apply regardless of the confidentiality level.

00:01:34

The 4th layer is DLP,

00:01:37

which stands for data loss prevention.

00:01:39

DLP rules automatically analyze content to detect,

00:01:43

for example,

00:01:44

sensitive personal or financial data.

00:01:46

These rules can alert or even block a risky

00:01:49

share when a file leaves its usual perimeter.

00:01:52

If your organization uses sensitivity labels,

00:01:55

you will see them in Word.

00:01:59

Excel

00:02:02

PowerPoint.

00:02:05

Or else Outlook

00:02:08

They directly protect the content,

00:02:10

and this protection remains active even

00:02:12

when the file circulates within Microsoft 365

00:02:15

or is transmitted elsewhere.

00:02:17

These labels are defined by your organization

00:02:19

in a dedicated data protection space.

00:02:23

Let's consider a very common example.

00:02:26

A budget file is stored within OneDrive.

00:02:29

It is then quickly shared in a team's channel to prepare for a meeting.

00:02:33

Someone then forwards the link further,

00:02:35

and the file is downloaded and sent outside the intended scope.

00:02:40

With a confidential label,

00:02:41

if it's available in your organization,

00:02:44

only authorized people could open this file.

00:02:47

Even if downloaded or transferred,

00:02:49

the protection remains active.

00:02:52

That's the power of a label.

00:02:54

It follows the file itself,

00:02:55

not just the location where it's stored.

00:02:57

Protecting information therefore,

00:02:59

means not only choosing its physical location,

00:03:01

but also controlling what actions can be performed with it.
