🧭 Where it fits¶
Security+ is the breadth baseline you earn early — before specializing. It pairs naturally with the rest of this repo:
- Offensive next step → the CEH hub adds the attacker's lens on top.
- Defensive / identity depth → the WALLIX / PAM hub operationalizes the access-control, identity, and least-privilege concepts Security+ surveys.
- Mechanisms → the protocols pages explain the crypto, TLS, Kerberos, SAML, and 802.1X that Security+ references.
- Career path → see the learning roadmap and platforms.
