- Incident response playbooks
Overview
Learn how to secure remote administration channels like SSH, RDP, and PowerShell using modern security principles, hardening techniques, monitoring, and zero-trust strategies.
The Problem
Remote administration tools provide attackers with direct access to critical systems and privileged accounts, making them prime attack targets.
The Solution
This book provides practical strategies to secure remote administration channels using authentication hardening, network controls, monitoring, and incident response.
About This Book
Secure Remote Administration in Modern IT Environments
Remote Administration Security Guide is a practical, security-focused handbook for protecting remote access technologies such as SSH, RDP, VNC, and PowerShell Remoting. Remote administration channels are among the most targeted attack surfaces in modern infrastructure, and securing them is critical for any organization.
