Security Testing
Basic Configuration Security Checker
Quickly audit your device or server configuration against industry-standard security baselines.
Configuration errors are the leading cause of successful cyberattacks. This tool helps IT administrators and home users perform a rapid security audit of their systems. By evaluating core controls like firewall status, password complexity, update frequency, and MFA deployment, it generates a security posture score and provides prioritized hardening steps aligned with CIS Benchmarks.
Security Posture Results
Audit your configuration to see your security score.
Posture Summary
Component Breakdown
| Control Area | Status |
|---|---|
| Firewall Config | - |
| Identity (MFA) | - |
| Patch Management | - |
| Least Privilege | - |
Posture Composition
Hardening Checklist
- Enable MFA: Deploy Multi-Factor Authentication for all primary and administrative accounts.
- Standard User: Use a non-administrator account for daily tasks to limit the impact of malware.
- Auto-Updates: Ensure your OS and all applications are set to update automatically.
- Disable Services: Turn off unnecessary features and ports (e.g., SMB v1, Remote Registry).
- Encryption: Enable full-disk encryption (BitLocker / FileVault) to protect data if the device is lost.
Audit Disclaimer
This tool provides a self-assessment score based on your inputs. It does not actively scan your system or verify settings. For a deep audit, use professional tools like Nessus, OpenSCAP, or Microsoft Security Baseline.
Configuration Disclaimer
Score reflects alignment with CIS Benchmarks Level 1 (Basic Hardening).
- No system is 100% secure; this score represents relative postural strength.
- Settings like "Firewall Enabled" are necessary but not sufficient for full protection.
- Consult with a security professional before making major system changes.

How to use this checker
Identify Your Platform
Select your primary operating system. Hardening requirements differ significantly between Windows, macOS, and Linux. For example, Windows focuses heavily on Registry settings and GPO, while Linux focuses on service permissions and kernel hardening.
Verify Firewall Status
Check your system settings to see if your local firewall is active. A "Strict" firewall blocks all unsolicited inbound traffic. A "Default" firewall might allow common services that could be exploited if not configured correctly. Never operate a device with the firewall disabled.
Assess MFA Deployment
Evaluate your use of Multi-Factor Authentication. MFA is the most effective defense against credential theft. "All logins" means every time you sign in to the OS or a web service. "Remote only" means you only use it for VPN or specific external access.
Review Update Hygiene
How do you handle security patches? Automatic updates ensure you are protected against "Day Zero" vulnerabilities as soon as a patch is released. Manual updates often lead to delays that leave your system exposed for weeks or months.
Check User Privileges
Are you logged in as an Administrator? If so, any malware that infects your session has full control over the system. Using a "Standard User" account for daily tasks is a core security principle (Least Privilege) that blocks most automated attacks.
Analyze Posture Score
The resulting score (out of 100) tells you how well your system aligns with basic security best practices. Use the "Hardening Checklist" to address any "Gaps" identified during the audit and re-run the checker to see your score improve.
Advantages of this checker
Identifies Common Blind Spots
Many users are unaware that using an admin account or disabling auto-updates creates massive security gaps. This tool highlights these common errors in a clear, quantified way.
CIS Aligned Methodology
The scoring logic is based on the Center for Internet Security (CIS) Benchmarks, ensuring that your "Security Score" reflects professional industry standards rather than arbitrary guesses.
Drives Proactive Hardening
The "Hardening Checklist" provides immediate, actionable steps. Instead of just knowing your system is "Low Security," you know exactly which five things to change to make it "High Security."
Low Friction Audit
Unlike complex vulnerability scanners that require installation and long scan times, this tool provides a postural estimate in under 60 seconds through simple self-reporting.
Platform Specific Guidance
The tool tailors its summary and recommendations to your specific OS, ensuring that a Windows user gets advice on BitLocker while a Mac user gets advice on FileVault.
Consistent Compliance Prep
Use this tool as a "Pre-Audit" before a formal security assessment. It helps you catch the "Low Hanging Fruit" so you can focus your professional audit budget on more complex architectural issues.
Governing bodies & standards
Q&A
What is a good security score?
A score of 80+ indicates strong alignment with basic hardening best practices. Anything below 50 requires immediate attention.
Why shouldn't I use an Admin account?
Malware runs with the permissions of the user. An Admin-level infection can disable antivirus and encrypt the entire disk.
Is a local firewall enough?
No, it is a "Defense in Depth" layer. You should also have a network firewall (on your router) and active endpoint protection (Antivirus).
What is the 'Least Privilege' principle?
The practice of giving a user only the access they need to perform their job, and nothing more.
How often should I audit my config?
At least once per quarter, or after any major OS update or software installation.
