Zero Trust

Agentic Cyberattacks: The Next Evolution of Cyber Threats Introduction For years, security teams have focused on AI-assisted cyberattacks—situations where attackers use AI to write better phishing emails, generate malicious code, or automate repetitive tasks. That era is already behind us. We are now entering the age of agentic cyberattacks, where AI doesn’t just assist attackers. It acts. Agentic cyberattacks involve autonomous AI agents capable of planning, executing, and adjusting multi-step intrusions without waiting for human direction. These attacks are strategic, adaptive, and continuous, and they represent one of the most significant shifts in cybersecurity we’ve seen in decades. ...

Explains how NIST 800 63-4 updates password and authentication guidelines to emphasize usability, stronger passphrases, and modern multi-factor security.

ETR-3: Zero Trust Architecture Lab Overview This hands-on lab will help you implement a small-scale Zero Trust Architecture (ZTA) using open-source tools. You’ll simulate secure access control, segmentation, and monitoring between multiple internal services. Lab Instructions 1. Lab Setup: Tools and Environment You will need: pfSense (in a VM or installed on Proxmox/VirtualBox) Docker and Docker Compose OpenVPN or WireGuard for identity-based remote access Optional: Suricata or Snort for traffic monitoring Network Design: Segment A: Trusted Users (e.g., Admin Workstation) Segment B: Internal Web App (Docker container) Segment C: Sensitive Service (Database container) All traffic flows controlled via pfSense firewall rules 2. Build the Network Segments in Docker Create an isolated Docker network and simulate services: ...

Why I Created Proftsec 🛡️ Cybersecurity is evolving faster than ever, and keeping up with threats, tools, and best practices requires constant learning. As a cybersecurity educator and practitioner, I saw a gap between theoretical knowledge and hands-on experience—so I created Proftsec.info as a platform to bridge that gap. The Problem: A Need for Practical Cybersecurity Learning Many cybersecurity resources are either too theoretical (lacking real-world application) or too advanced (assuming deep prior knowledge). My goal with Proftsec is to create a space that: ...
