The Cybersecurity Expert trek
From networking fundamentals to red team operations. Offensive and defensive security, cloud threats, incident response, and the certifications that open doors.
Networking fundamentals
TCP/IP, DNS, HTTP/S, TLS, and the OSI model as a mental framework for understanding every protocol-level attack.
Linux & OS internals
The file system, process model, permissions, capabilities, and kernel concepts that underpin every exploit and every defense.
Cryptography
Symmetric and asymmetric crypto, hashing, PKI, and the attacks on each. You don't need to implement crypto — you need to know when it's misused.
Web application security
OWASP Top 10, SQL injection, XSS, CSRF, SSRF, authentication flaws — and how to find and fix them before attackers do.
Network scanning & enumeration
Reconnaissance is the foundation of every engagement. Learn the tools, learn what they reveal, and learn how defenders see them.
Penetration testing methodology
The structured approach to pentesting: scoping, rules of engagement, exploitation, post-exploitation, and professional reporting.
Exploit development basics
Buffer overflows, shellcode, and understanding memory corruption — the foundation for reading CVEs and understanding what actually got exploited.
Malware analysis & reverse engineering
Static and dynamic analysis techniques for understanding what malicious code does — without running it blindly.
Cloud security
AWS, GCP, and Azure attack surfaces. Misconfigured buckets, SSRF-to-metadata attacks, IAM privilege escalation, and cloud-native defenses.
Defensive security & blue team
SIEM, EDR, detection engineering, and building the alerting pipelines that catch attackers before they achieve their objectives.
Incident response & forensics
When the breach happens: containment, evidence collection, timeline reconstruction, and the post-incident report that prevents recurrence.
Red team operations & threat modeling
Full-scope red team engagements, adversary simulation, MITRE ATT&CK-mapped TTPs, and the threat modeling skills that bridge offense and defense.
Certifications & capstone
Map your skills to industry certifications, build a public portfolio, and plan your career path across red team, blue team, cloud security, or AppSec.
