🔐 Executive-Level Access Control in Linux — Real-World Diagram

I was given a task to create an executive access control diagram for a corporate Linux environment, with a strong focus on visibility, security, and auditability.

This diagram represents a real-world enterprise structure where:

Executives can view financial data but never modify or delete it
Strategy documents are editable only by management
Board-level data remains isolated and protected
Auditors have read-only visibility across the entire system
sudo access is restricted to monitoring and audit commands only
Full ACL + auditd tracking ensures accountability and traceability

Technologies & concepts applied:

Linux users and groups
Least-privilege access model
POSIX permissions with ACLs
Sticky bit for controlled deletions
Restricted sudoers rules
auditd for compliance and activity tracking

Feedback, critique, and improvement suggestions are welcome.
