The Vault With Many Doors
why cloud security and identity and access management exist — controlling exactly who, and what, can reach specific data.
Part 1
Part 2
Before the Wall Was the Only Defense
how cloud security historically relied on a strong perimeter, and why that model stopped being sufficient.
Part 3
Checking ID at Every Door, Not Just the Gate
how zero trust security verifies identity continuously at every access point, rather than trusting broadly once past a single perimeter check.
Part 4
Only the Keys You Actually Need
how the principle of least privilege minimizes the damage any single compromised credential or misused access grant can cause.
Part 5
The Badge and the List of What It Opens
the foundational distinction between authentication (confirming identity) and authorization (determining permitted access).
Part 6
Badges Color-Coded by Department
how role-based access control (RBAC) grants permissions based on a defined role, rather than configuring access individually for each person.
Part 7
Rules That Consider Where and When, Not Just Who
how attribute-based access control (ABAC) adds context — time, location, device, data sensitivity — that role alone doesn't capture.
Part 8
A Badge for the Robot, Not Just the Employee
why service accounts and machine identities need the same rigorous access discipline as human employees, and often more.
Part 9
The Safe Inside the Vault
why encryption at rest protects stored data even if physical or logical access controls are somehow bypassed.
Part 10
The Armored Car Between Vaults
why encryption in transit protects data as it moves between systems, closing a gap that encryption at rest alone doesn't cover.
Part 11
A Separate Box for the Master Keys
why secrets management — protecting the credentials that protect everything else — deserves its own dedicated, hardened system.
Part 12
The Logbook That Records Every Door Opened
why comprehensive audit logging of every access request is essential for detecting misuse and reconstructing what happened during an incident.
Part 13
The Visitor Badge That Expires on Its Own
how just-in-time access and temporary credentials extend least privilege by making even minimal access automatically expire.
Part 14
The New Kind of Visitor That Never Sleeps
why AI agents represent a genuinely distinct identity category, requiring their own accountable, carefully governed access model.
Part 15
The Display Case With a Replica, Not the Real Jewels
how data masking and tokenization let people work with realistic-looking data without ever exposing the genuinely sensitive original.
Part 16
A Badge Honored Across Every Building
why maintaining consistent identity and access policy across multiple cloud providers is genuinely harder, and genuinely necessary.
Part 17
Watching the Staff, Not Just the Strangers
why insider threat monitoring — watching trusted, authorized access for genuine misuse — matters as much as defending against outsiders.
Part 18
The Inspector Who Checks the Vault Meets Standard
how compliance frameworks provide an external, standardized benchmark for verifying that security practices actually meet an accepted bar.
Part 19
What Happens When a Door Gets Breached
why a well-rehearsed incident response plan turns a security breach into a contained, manageable event rather than an open-ended crisis.
Part 20
The Whole Security System, Every Door Accounted For
reassembling every practice covered across this series into the complete picture of what disciplined cloud security and IAM looks like.
