Data Loss Prevention (DLP) in New Office 2016, SharePoint Online, and OneDrive for Business

Data Loss Prevention (DLP) in New Office 2016, SharePoint Online, and OneDrive for Business

Clients have benefited from Data Loss Prevention (DLP) technology within Exchange Online for years. Microsoft is now expanding the functionality to cover data and documents that may be in Office, SharePoint, and OneDrive. Plus they are enhancing the console where the policy rules are managed so that the policy rules for all of the services are controlled in a single location.

Client can continue to use the templates that Microsoft builds to help them stay compliant with regulations like PCI and HIPPA. Severity levels can also be set – so administrators, for example, could have one set of actions that happen if a user tries to send a credit card number externally and another if they are trying to send a file that contains ten or more credit card numbers in it.

DLP not only is for people who are actively trying to share content that they shouldn’t, it is also for people who didn’t notice that there was a company credit card contained 10 emails down in a thread before they forward it to a new distribution list.

Office 365 Security Overview

How is Microsoft Protecting Your Data From Government Snooping?

There have been a growing number of stories related to government surveillance of internet data in recent days. Our customers have taken notice and we have heard a number of concerns related to the privacy of their data in Microsoft’s Cloud.

While we share in these concerns, the bottom line is Microsoft is doing everything they can to keep your data safe. More importantly, there is no indication that any of Microsoft’s data has been breached by the government. We are told that on the business platforms, Microsoft has had only a handful of requests to share data with the government and was able to work with clients to provide notice and assistance in the vast majority of the cases.

A recent press release explains what Microsoft is doing to keep your data private.

Highlights include:

Expanding Encryption:

  • Microsoft is expanding or strengthening encryption across all of its services; particularly while data is transmitted over the internet
  • If you are on Office 365, Microsoft already encrypts all information moving between your business and Microsoft, and Microsoft’s internal data centers by default
  • These communication channels are protected by best-in-class cryptography including Perfect Forward Secrecy and 2048-bit Key lengths
  • All information which is stored in a Microsoft data center is protected by industry leading encryption and security protocols

Reinforcing legal protections:

  •  Committed to notifying any company when Microsoft receives a government request for access to their information
  • Working with other cloud providers to make the government go directly to an individual company, rather than a cloud provider, to obtain data

Increasing Transparency:

  •  Increasing the transparency of their software code, making it easier for customers to see for themselves that Microsoft products do not contain back doors.
  • Opening a network of transparency centers in the US, America and Asia

How Unsecure Is the Cloud?

How Unsecure Is the Cloud?

Clients frequently ask our team about security in the cloud and how their data is protected.  We spend a ton of time with them walking them through the features of security that Microsoft has built.  Generally, the discussion boils down to two topics:

Even though the cloud isn’t perfect for security, it is exponentially better than what is currently protecting the same data at the client’s site.  Frequently, the customers who question the security of the clouds are the same ones who believe that a firewall and antivirus is strong security.  In my opinion, it is the bare minimum.  Taking these clients to the cloud provides a level of security that they have never seen and likely could never make the investment for.

Security by obscurity – many smaller clients believe that they have a level of security provided by the fact that they shouldn’t be a target.  “No one knows who we are.”  “No one knows our network is here.”  These arguments tend to fall apart with the use of automated tools that aren’t targeted.  They are just pointed at people’s internet addresses and sent to try and open as many doors as possible.  These automated bots do not discriminate like a human would – they will go after any and all data.  Our general advice is to remove the Exchange server which is one of the chattiest services on the network – it will talk to anyone.  And if a client really wants security by obscurity, Microsoft’s Office 365 service is so large that their mailboxes are sure to be lost in the mix.  If they find that comforting.
