📅 Date Started: 2026-05-08
📅 Date Completed: 2026-05-08
🎯 What I Learned:
- Firmware security: Understanding firmware vulnerabilities, updates, and protection against hacking
- System security fundamentals: Securing the foundation layer of computing devices
- Operating systems: Types and security features of Windows, macOS, and Linux
- Server security: Different server types and their security requirements
- OS hardening: Techniques for securing host operating systems through configuration
- Patch management: Keeping systems updated to address known vulnerabilities
- Security best practices: Disabling unnecessary services, event logging, secure authentication, and backups
- Device modification risks: Understanding jailbreaking and rooting implications
💡 Key Takeaways:
- Firmware is the foundational layer that requires protection as much as software
- OS hardening reduces the attack surface by removing unnecessary components and services
- Each operating system (Windows, macOS, Linux) has unique security features and requirements
- Regular patching and updates are critical for closing security gaps
- Defense in depth at the system level includes authentication, logging, and backup strategies
- Jailbreaking/rooting devices removes security controls and increases vulnerability
