Authentication, Research, And Routine Discipline

Lab Notes — September 21, 2025

Sysadmin Work

• No major sysadmin updates logged this day.

Security+ Studies

• Compared Authy vs Google Authenticator vs Microsoft Authenticator.
• Reviewed Apple’s security code system.
• Learned what a YubiKey is and how it strengthens MFA.
• Continued reinforcement of access control and risk concepts.

Security Research

• Explored grassroots hackers definition and relevance.
• Looked into AI security research paths, including ensemble learning and random forests.
• Researched Hands-On Machine Learning with Scikit-Learn, Keras, and TensorFlow (chapters, book structure, potential use for AI security focus).
• Logged interest in Meetup group studying ML with this book (noted chapter 7 status).

Notes

• Reflected on personal study routine (8–5 work, 5–9 study, weekends for meetups/congregation).
• Balanced focus between Security+ path (Sec+, CCNA, Red Team certs) and curiosity-driven AI/ML exploration.
