F11 Labs
Engineering systems under real conditions.
F11 Labs is a personal engineering lab used to design, test, break, and harden modern IT environments.
This site documents what was built, what failed, and what fixed it — without theory padding or marketing language.
Purpose
F11 Labs exists to validate real-world IT engineering decisions through hands-on execution.
Every lab published here reflects:
Real configurations
Real failures
Real troubleshooting paths
Nothing is simulated purely for demonstration.
Nothing is published without being tested.
Scope of Work
Identity & Access Engineering
Microsoft Entra ID, Conditional Access behavior, MFA enforcement, legacy authentication removal, and sign-in analysis.
Cloud & Hybrid Infrastructure
Azure and GCP labs, hybrid Active Directory, tenant baselines, and integration testing.
Security Controls & Hardening
Zero Trust validation, access boundaries, policy enforcement, and failure impact testing.
Architecture & Documentation
Clear diagrams and technical notes taken directly from live labs.
What this Is Not
This is a working lab and a permanent engineering record.
Not a blog site
Execution, not articles.
Not a tutorial site
Outcomes over instructions
Not a news feed
Systems over stories.
Not a marketing site
No promotion. Just proof.
Who This Is For
Engineers, administrators, architects, and security practitioners who care more about execution than opinions.
If you’ve broken production systems before — you’ll feel at home here.
Maintained by Jaspreet Singh
DevOps & Identity Engineer — cloud, infrastructure, and security systems.
Simple. Timeless. Credible.
What you will gain
Real-world system states
Configuration decisions and trade-offs
Failure scenarios and recovery paths
