The fastest way to fall behind in cybersecurity is to start with tools before understanding what the tools are measuring. Canadian beginners should start with networking fundamentals first: TCP/IP, DNS, HTTP/HTTPS, TLS, routing, switching, subnetting, NAT, firewall logic, and segmentation.
That foundation translates into every later path, whether you move into SOC analysis, cloud security, incident response, network engineering, DFIR, or detection engineering. It also makes certifications and school coursework easier because you can connect theory to real behavior.
Use the hack3rs.ca curriculum as the main sequence, and treat external docs and videos as supplements. The goal is not to consume content quickly. The goal is to understand normal system behavior deeply enough to detect and explain abnormal behavior.
