Recent field notes
Authorization Drift: When Permissions Outlive Their Purpose
Authorization drifts when roles, grants, service accounts, and exceptions remain after the work that justified them ends.
Vendor Remote Access Without Permanent Trust
Vendor access should be named, scoped, approved, observed, time-limited, and removed when the work is complete.
Dependency Admission Policies for the Build Pipeline
Dependency admission policies evaluate source, maintenance, license, integrity, and risk before packages enter the trusted build path.
Securing Out-of-Band Management Before You Need It
Out-of-band management must remain isolated, attributable, and available when the production network cannot be trusted.
Secrets Have Lifecycles Too
Secrets should be requested, issued, scoped, delivered, observed, rotated, revoked, and destroyed through a controlled lifecycle.
Network Segmentation by Risk, Not Just Department
Useful segmentation separates systems by trust, exposure, impact, and management needs instead of organizational charts alone.
Authentication Is Not Authorization
Authentication proves identity; authorization decides what that identity may do in a specific context.
Physical Access Control for Server Rooms and Network Closets
Physical access controls should connect identity, authorization, evidence, environmental safety, and emergency recovery.
