Thoughts on IT security, DevSecOps, and Linux systems.
A practical breakdown of Kubernetes RBAC — how to move beyond default permissive configs, enforce least privilege with Roles and ClusterRoles, and avoid the subtle misconfigurations that leave clusters exposed.
Passwords alone are a liability—this post walks through implementing MFA and passwordless authentication using FIDO2, Azure AD, and conditional access policies, with real configuration examples you can adapt for production environments.
LDAP directories are the backbone of enterprise identity, yet misconfigurations like anonymous binds, cleartext authentication, and overly permissive ACLs silently expose organizations to credential theft and lateral movement. This post walks through practical hardening steps with real configuration examples you can deploy today.
Most breaches don't start with a zero-day—they start with a compromised privileged account. This guide walks IT operations teams through implementing PAM controls that actually survive contact with production environments, from just-in-time access to hardened sudo policies and vault-backed credential rotation.
Active Directory remains the most targeted identity infrastructure in enterprise breaches, yet most environments still run with default configurations that attackers exploit in minutes. This guide walks through actionable hardening techniques, detection strategies, and governance frameworks that security administrators can implement immediately.
Unmonitored privileged sessions are the blind spot that breach investigations always wish they'd closed. This post walks through architecting session management controls that capture, constrain, and audit every administrative action across your enterprise infrastructure.
A practical guide to hardening IAM across cloud and on-premises environments, covering least-privilege enforcement, MFA implementation, service account hygiene, and automated access reviews—with real configuration examples you can deploy today.
