Secure Baselines

Secure baselines provide standardized checklists for hardening IT equipment, drawing from sources such as product developers, vendors, government bodies like NIST, and security organizations. Organizations typically adopt, adapt, or combine these baselines to fit their specific environments.

About this video

Secure baselines are standardized sets of security configurations used to harden IT equipment consistently and systematically. Rather than approaching each device ad hoc, organizations rely on these baselines as authoritative checklists that define exactly what hardening steps are required for a given system or technology. This structured approach reduces the risk of misconfiguration and ensures that security controls are applied uniformly across an environment. Baselines can originate from several authoritative sources. Product developers often publish hardening guidance specific to their own software or hardware, while vendors provide configuration recommendations tailored to their products. Government agencies such as the National Institute of Standards and Technology (NIST) publish widely adopted baseline frameworks, and nonprofit or private security organizations contribute additional resources. In most real-world scenarios, security teams evaluate multiple sources and either adopt a single framework or merge several into a custom baseline suited to their organization's specific needs and risk profile. Establishing and deploying a baseline is only part of the process. Ongoing maintenance is equally critical, as baselines must be reviewed and updated regularly to reflect changes in technology, newly discovered vulnerabilities, and evolving industry standards. An outdated baseline can create the same exposure as having no baseline at all, making continuous upkeep a core responsibility for any security team managing hardened infrastructure.

Key terms

Baseline: A documented set of minimum security standards or performance metrics used as a reference point.
Configuration Management: The process of tracking and controlling changes to hardware, software, and documentation throughout a system's lifecycle.
Patch Management: The process of acquiring, testing, and installing software updates to fix vulnerabilities and improve functionality.
Hardening: The process of securing a system by reducing its attack surface — disabling unnecessary services, applying configuration best practices, removing default credentials, and keeping software patched. Hardened systems offer fewer opportunities for exploitation.

Transcript

With each piece of equipment, we could be taking different steps to go through this hardening process. But how do we know which steps we need to do on different pieces of equipment? We can use secure baselines to do that, to understand what it is that we need to do to harden pieces of equipment.

Think of secure baselines as the checklist of what we need to do to harden a piece of equipment.

Where Secure Baselines Come From

Some sources where these secure baselines come from would be, if the product is being developed, whoever is developing that product would create these secure baselines. Also, product vendors: whoever is selling these products will also create secure baselines that we can follow. Or there are a lot of government and other organizations, nonprofit organizations, that will create baselines that you can follow — NIST is an example of that. And then there are also security vendors that are out there that will create secure baselines that we can utilize.

What I have found is that you go and do some research and then you create your own baselines that you are going to follow. So you either choose to follow one of these others, or kind of merge them together to create your own self-created baselines.

Establish, Deploy, Maintain

Essentially what we need to do is establish what those baselines are going to be, and deploy those baselines. But then there's also a maintenance that occurs with this, that you want to make sure that those baselines continue to be updated as things change.
