Security+ is broad, vendor-neutral, and tied to real exam constraints. The current CompTIA exam is SY0-701. It costs $425, allows maximum of 90 questions in 90 minutes, and requires 750 on a scale of 100-900 to pass.

Security Operations (28%): Can you sequence the six incident response phases correctly? Can you describe what containment means and why it precedes eradication? Can you list five hardening actions for a server?
