Think Positive Cyber

Today, I dove deep into critical cybersecurity architecture concepts in preparation for the CompTIA Security+ certification exam (SY0-701). I explored redundancy, including geographic dispersion, load balancing, and clustering for network reliability. I reviewed primary and backup domain controllers, why email services should run on non-primary systems, and the importance of placing DNS and DHCP for optimal performance. I studied RAID configurations—including RAID 0 (striping), RAID 1 (mirroring), RAID 5 (parity), and RAID 10—plus snapshot technology, virtual desktop infrastructure (VDI), and storage imaging.

I also reflected on site resiliency planning: differences between cold sites, warm sites, and hot sites, and how they impact disaster recovery (DR) timelines. Cybersecurity insurance now comes with security hygiene checklists, reminding us that backups, patching, and power planning must be proactive. Considerations like patch availability, power consumption, risk transference, and compute requirements can make or break an IT operation. Vendors like Cisco, Dell, and SonicWall also vary in deployment ease and long-term support.

With Security+ prep in full swing, I’ll head to EoS Fitness this evening to stay physically sharp—then refuel with well-earned hamburgers 🍔. It’s all part of my plan: balancing cybersecurity study, physical fitness, and mental well-being.
