What Are Security Baselines

If you’ve ever wondered how orgs “harden” Windows without guessing, security baselines are part of the answer. They’re a packaged way to spell out what settings to use, why they matter, and how to apply them across devices.

Security baselines vs baseline controls (minimum controls for impact levels)

People mix these terms up, so here’s a clearer way to separate them.

• Baseline controls are the minimum security controls an organization defines based on how risky a system is.
• The definitions are typically grouped by impact levels like low-impact, moderate-impact, and high-impact.
• “Impact level” is a way to match the security effort to how bad a breach would be.
• Security baselines are what you get after those minimum controls turn into specific security settings and configurations you can actually implement.

A useful chain to keep in mind is:

baseline controls (minimum rules by impact) → security baseline (packaged settings to meet them) → security implications (what you gain and why it matters)

How Microsoft security baselines are described (configuration settings + security implications)

When people say Microsoft security baselines, they’re usually referring to a set of Microsoft-recommended configuration settings.

The key part is the “why” that comes with the settings. In other words, Microsoft ties the configuration choices to the security implications—what the change is meant to improve or protect against. It’s not just “turn on X.” It’s “configure X because it affects security.”

That framing is also why baselines are easier to adopt than random checklists. They’re meant to explain the security meaning behind the configuration.

What Microsoft Intune security baselines do for Windows devices

Microsoft Intune security baselines are different in how they’re delivered, even though the goal is the same.

Instead of being a list meant for people to configure manually, Intune baselines are described as:

• preconfigured Windows settings
• that you can apply and enforce
• so you can roll out more granular security settings on Windows devices

So, in practice, Intune baselines turn the baseline idea into something operational. You’re not only documenting what should be set—you’re pushing a consistent baseline out to devices and keeping it there.

Windows security baselines: what “preconfigured Windows settings” means

“Preconfigured Windows settings” just means:

• the settings are already packaged
• with the Windows-specific details needed to apply them
• so you can select a baseline and move forward without starting from scratch

This matters because Windows has security options spread across different areas. Baselines help pull those pieces into a shared, repeatable structure.

And because baselines are framed around security implications, they’re usually meant to help you avoid two common problems:

1. Setting something insecure “by accident”
2. Changing settings without understanding what they affect

What are the Microsoft security baselines for Windows 11?

At a high level, “Microsoft security baselines for Windows 11” means:

• Microsoft provides baseline packages
• made up of Microsoft-recommended configuration settings
• and those baselines include security implications
• intended for use with a Windows 11 environment

In plain terms: a Windows 11 baseline is Microsoft’s recommended starting point for securing Windows 11, expressed as packaged configuration settings.

If you’re using Intune, the Intune side is what helps you actually apply and enforce those baseline ideas on Windows devices.

What are security baselines examples (Windows-focused examples to look for)

Since you asked for examples, here’s the general “shape” to look for when you’re reading Microsoft or Windows baseline material, without needing to dive into specific setting names.

You’ll usually see items that look like:

• a named baseline (for example, something tied to a Windows version or a particular role)
• groups of configuration settings
• each tied to an explanation of security implications
• and, often, packaging that matches how you can roll the settings out consistently

You may also see baselines discussed alongside “baseline controls,” such as:

• minimum control expectations tied to low-, moderate-, and high-impact environments
• plus the configuration settings that support those minimums

The easiest way to tell a real baseline from a random “do these toggles” list is to look for whether it’s framed as a group of recommended settings with security meaning, not just a pile of switches.

How to think about recommended Windows security settings when adopting a baseline

A baseline can be a strong starting point, but you still need to fit it to your environment. Here’s a beginner-friendly way to decide where to start.

1) Decide what “minimum” means for your environment

Because baseline controls are defined by impact level (low, moderate, high), start by asking:

• What kinds of systems do you have?
• What would be the impact if one of them is compromised?

That helps you choose which baseline level you’re trying to meet.

2) Treat the baseline as a structured target, not a checklist

A security baseline isn’t “do these 100 things.” It’s more like:

• a structured set of recommended configuration settings
• intended to support the minimum security controls
• with security implications that help you understand the trade-offs

When you keep it structured, you’re less likely to end up with systems that are only half-configured.

3) Use the enforcement tool so you don’t lose consistency

If you manage Windows devices at scale, the point of Intune security baselines is that they’re preconfigured Windows settings you can apply and enforce.

Consistency is the goal. If settings drift from device to device, it’s hard to claim you’re following a baseline.

4) Expect “recommended” to still require judgment

“Recommended Windows security settings” comes with Microsoft guidance, but you still have decisions to make, like:

• which devices should receive it
• when to roll it out
• how to handle systems that behave differently in your environment

The baseline gives you a solid target. Your job is to apply it in a way that makes sense for your situation.

Where to find security baseline downloads (Windows 11/Windows 10 and later, Server)

If you’re looking to get the files or packages, you’ll want baseline downloads for the Windows versions you support, plus Server.

Look for baseline resources that cover:

• Windows 11
• Windows 10 and later
• Server

And if you’re working with Microsoft Intune, also look for how baselines are packaged so they can be:

• applied to devices
• enforced using Intune’s approach to managing Windows settings

If you’re planning to adopt Windows security baselines, use this definition map to decide what to baseline first and how to enforce it. Start with the impact level (baseline controls), move to the packaged settings (security baselines / Microsoft recommendations), then choose the tool path that helps you apply and keep everything consistent (like Intune).
