For SMBs, Microsoft provides a brand new layer of server safety
Microsoft this month unveiled a preview of server safety geared toward small and mid-sized companies, bundling the added safety with Microsoft Defender for Business.
Do you run a small enterprise with on-premises servers?
Chances are, you depend on know-how that features servers, whether or not they’re Windows- or Linux-based. With that in thoughts, Microsoft just lately introduced it’s previewing “server protection for small business” — bundling the providing with Microsoft Defender for Business.
This is noteworthy as a result of till now, most Endpoint Detection and Response (EDR) options have been costly and sometimes solely deployed by bigger enterprises. (EDR is an built-in, layered strategy to endpoint safety that mixes real-time steady monitoring and endpoint information analytics with rule-based automated response.)
As Microsoft notes within the weblog publish asserting the transfer:
“The Microsoft Defender for Business servers experience delivers the same level of protection for both clients and servers within a single admin experience inside of Defender for Business, helping you to protect all your endpoints in one location.”
Currently customers can activate a trial for every server via the Microsoft 365 Defender safety portal (which additionally recommends safety settings to make your servers safer). When Microsoft formally releases the product, it’ll price $3 per server, per 30 days. If you’re a Microsoft 365 for Business buyer, you may start a trial and see what affect deploying it to your servers can have.
There are a number of methods to onboard servers; you should utilize native scripts, group coverage, or Configuration supervisor. One of the best methods to check out the brand new providing is to make use of the script course of. First, activate preview choices by going to https://safety.microsoft.com, go to Settings > Endpoints > General > Advanced options > Preview options. (Here’s a extra direct hyperlink.)
In the navigation pane, select Settings > Endpoints, after which underneath Device administration, select Onboarding. Now choose an working system, reminiscent of Windows Server 1803, 2019, and 2022, and within the Deployment technique part, select Local script. Note: for these newer programs, you solely want run this script; no different set up steps are required. Simply run the command line as an elevated command. (If you don’t present the onboarding script with the right permissions, it’ll provide you with a warning to take action.
For older software program reminiscent of Windows Server 2012 R2 and 2016, you may have two packages to obtain and run: an set up bundle and an onboarding bundle. The set up bundle particularly incorporates a file that installs the Defender for Business agent. Once you run the set up file, you run the script as if on one of many newer server platforms. Newer servers (and workstation working programs) embrace the code for onboarding defender robotically.
The particular command file to onboard servers is called WindowsDefenderATPLocalOnboardingScript.cmd. Your server ought to present up within the Defender console, although it’s not instantaneous. It would possibly take a short time to point out up.
Now, it’s time to evaluate the suggestions and alerts.
First off, Defender offers you a timeline view of your programs — consider this as a cloud forensic system. You will quickly discover out that your servers (and for that matter your workstations) are very energetic objects, continually sending instructions and exercise.

Defender’s view of your programs.
For instance, within the display above, “MpCmdRun.exe” is the Microsoft Malware Protection Command Line Utility and it’s performing actions on the server. In the column on the precise, it flags the potential safety method getting used. Note that on this occasion, the exercise will not be malicious, the console is barely retaining observe of regular server actions. In this case, it’s recognized as a MITRE “credentials from password stores” exercise.
Next, within the safety suggestions part, you’ll see prompt changes you should utilize to higher safe your small-business servers.

In the safety suggestions part, you’ll see ideas to higher safe your servers.
Many of those suggestions must do with Attack Surface Reduction guidelines that we regularly neglect to allow on server installations.
Linux servers may also be onboarded to the Defender for Servers console, although it’s unclear to me whether or not Linux-based Network connected storage items could be absolutely supported. Reach out to your NAS distributors to find out whether or not they’ll help using Defender for Servers in your Linux units. To onboard a Linux system to your console, you’ll comply with comparable set up procedures. You can use a guide deployment script or Puppet, Ansible, or Chef configuration administration instruments.
Supported Linux server distributions embrace:
- Red Hat Enterprise Linux 6.7 or greater (Preview).
- Red Hat Enterprise Linux 7.2 or greater.
- Red Hat Enterprise Linux 8.x.
- CentOS 6.7 or greater (Preview).
- CentOS 7.2 or greater.
- Ubuntu 16.04 LTS or greater LTS.
- Debian 9 or greater.
- SUSE Linux Enterprise Server 12 or greater.
- Oracle Linux 7.2 or greater.
- Oracle Linux 8.x.
- Amazon Linux 2.
- Fedora 33 or greater.
Be conscious that that checklist doesn’t embrace particular Linux distributions I typically see in small enterprise. For instance, I routinely see NAS units reminiscent of Synology in small companies, and I’m undecided whether or not these will probably be supported by Defender for Servers. (I’ll be giving Microsoft suggestions that it wants so as to add these fashion of NAS units to the help matrix.)
Also unclear at the moment is the precise licensing construction required to make use of Defender for Servers. Currently, Defender for Endpoint for Server licensing mandates a sure minimal variety of customers (50). It’s unclear what variety of Microsoft Defender for Business licenses might be owned to qualify for Defender for Servers or whether or not a minimal variety of licenses is required. We’ll have to attend till the product is formally launched to know the way the licensing works.
Bottom line: should you run a small enterprise, I urge you to check out Defender for Servers. It will convey further safety to your small-business community.
