Episode 14: Gap Analysis and Zero Trust Security (Domain 1)
from Certified: The CompTIA Security+ Audio Course Hosted by Dr. Jason Edwards
Security programs are only as strong as their weakest uncovered areas—and that’s where gap analysis and Zero Trust come into play. This episode introduces gap analysis as a structured approach to identifying where an organization’s current security posture fails to meet expected or required standards, often using frameworks like NIST or ISO to benchmark practices. We discuss how gap analysis involves comparing existing controls, processes, and risks against desired outcomes or compliance objectives to generate actionable remediation plans. Then we turn to Zero Trust, a transformative security model based on the principle of “never trust, always verify.” Zero Trust assumes breach and requires continuous authentication, authorization, and validation at every access point, regardless of whether a request originates inside or outside the network perimeter. By combining gap analysis with Zero Trust principles, organizations can not only uncover deficiencies, but also redesign their infrastructure to eliminate implicit trust and reduce exposure.
