Establish a basis for decisions
Target endpoint groups and inspect settings actually measured. Identify configuration gaps within the scopes you have prioritised.
Attack surface
Reduce your exposure
An endpoint’s attack surface includes the entry points an attacker could exploit. Weak configurations and unnecessary active features contribute to that exposure. Cyberlib identifies configuration gaps and helps teams prioritise hardening actions.
EXPOSURE ASSESSMENT
See what increases exposure
Unnecessary accounts and services, default settings and misconfigured encryption can leave entry points open. Configuration audits show where supported Windows, Linux and macOS endpoints differ from the selected baseline.
Balance security and operations
Assess observed gaps alongside the security value of settings, known impacts and business constraints. Prioritise changes with the owners of affected services.
Verify outcomes
After deployment, run another audit to verify resulting configurations. Track the hardening plan using remaining gaps, beyond deployment status alone.
HARDENING DEPLOYMENT
Prioritise corrective action
Settings have different security values, dependencies and operational impacts. Focus on changes that address relevant exposure, validate them on a pilot group and check the results after application.
Define the expected protection
Choose catalogue settings suited to your systems and usage: access protection, system restrictions or service configuration, depending on available settings.
Prepare changes with operations
Organise settings into batches and review changes before application. Include prerequisites, restarts and side effects in change preparation.
Validate before wider deployment
Assess templates on a pilot group representative of business usage. Then extend their application to relevant groups according to your schedule and operational constraints.
MITRE ATT&CK
Connect priorities to MITRE ATT&CK
Cyberlib maps hardening settings to MITRE ATT&CK techniques and mitigations to inform decisions. Successive audits also help identify regressions after updates, interventions or new endpoint deployments.

Connect threats to technical measures
Use available mappings between hardening settings and MITRE ATT&CK mitigations to explain the protection objective.
Align security and infrastructure teams
Use a shared knowledge base to discuss relevant attack techniques and configurations to harden with deployment teams.
Substantiate protection decisions
Frame settings in terms of exposure reduction. MITRE mappings complement audit findings and impact analysis to inform decisions.
CROSS-PLATFORM COMPATIBILITYWindows, macOS, Linux.
Windows, macOS, Linux.
One commitment to security.
Cyberlib is compatible with Windows, macOS and Linux. Define templates for the systems, versions and usage of relevant groups to bring heterogeneous environments into one hardening programme.

Linux
Distribution-aware configurations
Linux, in all its diversity.
Ubuntu, Debian, Red Hat Enterprise Linux, Fedora: distributions have their own versions, services and configuration mechanisms. Applicable settings and benchmarks depend on the distribution and version.

THE QUESTION THAT MATTERS
What is an endpoint’s attack surface?
It is the set of entry points and weaknesses that an attacker could exploit, including weak configurations and unnecessary enabled features.

complementary roles.
The aim is to connect the intended configuration, the tools used to deploy it and detection capabilities. Each tool’s exact scope depends on its features and your licences.
CYBERLIB
Reduce exposure
Define a baseline configuration, apply templates and measure gaps. Hardening addresses overly permissive settings before they facilitate an attack.
EDR / XDR
Detect and respond
Security tools monitor behaviour, support investigations and trigger responses. Their alerts can also inform reactive hardening workflows.
GPO / MDM / UEM
Manage and deploy
Management tools distribute configurations within their scope. Cyberlib provides a hardening approach and uses compatible integrations to execute it.

Talk to Cyberlib ↗How does Cyberlib reduce the attack surface?
By auditing configurations, identifying gaps and helping prioritise hardening settings according to security value and operational impact.
Talk to Cyberlib ↗How is hardening maintained over time?
Successive audits and drift tracking help identify regressions. Sustained hardening depends on check frequency, equipment availability and corrective action.
Talk to Cyberlib ↗How does a configuration audit differ from a penetration test?
A configuration audit measures deviations between system settings and an expected baseline. A penetration test attempts to exploit weaknesses within an agreed scope. Cyberlib audits help steer hardening and verify configurations; they complement other security assessments.
Move from auditing to hardening ↗How does MITRE ATT&CK support hardening?
MITRE ATT&CK describes attacker tactics and techniques. Cyberlib maps hardening settings to this framework to inform configuration priorities. A mapping does not guarantee that an attack technique is fully blocked: it helps explain a control’s contribution to defence in depth.
