About this track
Core security concepts - CIA triad, memory safety, binary hardening, crypto hardware, and kernel security mechanisms.
The Security Fundamentals track collects 5 modules and 20 lessons into a single ordered path. Each module ends with a checkpoint quiz; passing the checkpoint unlocks the next module so you can track your progress without guessing whether the material has stuck.
You start with "Security Fundamentals" and finish on "Kernel Security Mechanisms". The whole track sits inside the Security area of the curriculum, so the writing assumes the prerequisites listed above and skips ground that an earlier track has already covered.
What this track covers
- Security Fundamentals — How computers protect data - encryption, authentication, and common vulnerabilities at the hardware and software level.
- Memory Safety & Exploitation Primitives — A systematic taxonomy of memory corruption classes and the fundamental building blocks attackers use to turn bugs into exploits.
- Binary Hardening & Compiler Defenses — How compilers and linkers protect binaries against exploitation - stack canaries, CFI, heap hardening, and security-critical compiler flags.
- Low-Level Authentication & Crypto Hardware — Hardware roots of trust, cryptographic acceleration instructions, secure enclaves, and how keys are managed at the firmware and hardware level.
- Kernel Security Mechanisms — Linux Security Modules, Windows kernel security, process sandboxing techniques, and hypervisor-based security isolation.
How the track works
Every lesson is a short page with diagrams, runnable examples, and the kind of edge-case footnotes you usually only find in textbooks. Where it makes sense, the lesson is paired with a CPU simulation or a coding challenge so you can poke at the idea instead of just reading about it.
The lessons themselves are free to read with a free account. The 5 checkpoint quizzes that gate the next module are also free, as are the lesson IDE and CPU simulations. Optional 777-tier tools — the step-through debugger, decompiler, ROP gadget builder, heap visualiser, and exploit labs — sit alongside the lessons but are not required to follow the track from start to finish.
You can jump in at any point. Be Bitwise is built around a free forever curriculum, with no time limits and no expiring access. Pick the next lesson when you have an hour; come back when you do not.
