A defender guide to cloud identity abuse prevention, focusing on IAM drift, control-plane logging, role scope, and fast incident triage for suspicious admin actions.

$ tag: Cloud / IAM

How to detect ransomware operations before impact by focusing on lateral movement, backup tampering, credential abuse, and service changes rather than waiting for encryption alerts.

$ tag: Ransomware / Detection

How to run a defender-grade edge audit: inventory exposed services, compare drift, prioritize by exploited vulnerabilities, and validate remediation with evidence.

$ tag: Exposure / Patch Prioritization

A detailed defender guide to handling tax-season phishing and credential harvesting: what attackers do, how to detect early signals, how to triage accounts safely, and how to reduce repeat incidents.
