The Shared Responsibility Model & Microsoft 365
The shared responsibility model. You may have heard of it, but do you know what it is or what it means for your business? Before we jump in, there are a few things that you need to understand about your cyber security.
With more and more businesses using cloud services like Microsoft 365 (MS 365), they are starting to become the standard. And though we do recommend the use of the cloud, you must also assess your risks when using these platforms. Take a minute to think about what could happen, even if you think there is little to no chance a breach or cyber attack could happen to you, they need to be considered.
We often hear businesses say that they don’t need to worry about cyber security because they’ve never been breached or hit with ransomware. Former IBM Ginni Rometty said cybercrime “the greatest threat to every profession, every industry, every company in the world.” and Former FBI Director James Comey said “There are two kinds of companies in the United States. There are those who’ve been hacked … and those who don’t know they’ve been hacked.”
At this point, the discussion about cyber attacks should be based on the assumption that every business will eventually by affected. It’s time make cybersecurity a priority and to protect your organization, employees and clients.Not sure if your 365 is secure? Download this free checklist.
What Is the Shared Responsibility Model?
In an on-premises datacenter you are responsible for everything including security. As you move workloads to the cloud, some responsibilities transfer to the Cloud Service Provide (CSP), hence the concept Shared Responsibility model.
When moving workloads to the cloud it’s critical to understand the shared responsibility model including which security tasks the CSP is responsible for and and which tasks your organization is responsible for. They will vary depending on whether the workload is hosted on Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS), or in an on-premises datacenter
With cloud services improving and evolving, people often use them with blind trust and a lack of understanding of who is responsible for what. They assume that because the technology is advancing, they are going to be kept safe when using the cloud. But that is typically not the case when you are running with the default settings.
It’s On YOU: Cloud Security
Cloud services are not responsible for protecting your information. That bears repeating. It is your responsibility to keep your business safe. Understanding your risks is critical, because breaches, ransomware and other attacks are not scary hypotheticals, they actually happen with increasing regularity and impact. You need to understand what the cloud will do to assist you in protecting yourself, and what you need to take upon yourself.
Microsoft 365 Shared Responsibility Model
With Microsoft 365, there are a variety of aspects to the shared responsibility model. Here are the most critical to take into your own hands:
- Microsoft 365 is NOT obligated to protect the loss of your data in the instance of an app outage. Though Microsoft takes many measures to keep service up and running, in the instance of an outage, there may be a loss of your data. You need to know that Microsoft is not liable for this. Microsoft makes it clear that in order to keep your data safe, you should back it up with a third-party application.
- Microsoft is NOT liable for data loss due to a deprovisioned user account. Their policy states that information is kept for 90 days after the termination of an account. If you terminate your MS 365 account and do not retrieve or back up your information with a third party, it will be permanently lost after the 90-day period is up.
- Microsoft is NOT liable for data loss as a result of data that was inadvertently or maliciously deleted. If a user accidentally or maliciously deletes data and it is not discovered for more than 90 days, it is lost forever.
Backups aren’t the only security concern. Microsoft 365 comes with a variety of security features, but it is up to you to configure them for your business. Check out the 21 critical controls we recommend in our Microsoft 365 Security Checklist.
