Project Design Purpose : This article will introduce the detailed design methodology and functional objectives for implementing the Warning, Alarm, and Fault Alert Sub-System within the Mini OT Aviation CAT-II Airport Runway Lights Management Simulation System (version : v_0.2.2). This subsystem plays a crucial role in supporting cyber exercise and incident response training which focused on airport operational technology (OT) safety, reliability, and cybersecurity awareness by using the cyber range system.This design document introduces the following three core development areas:Alert Logic a...

Program Design Purpose: The primary objective of this program is to leverage AI-LLM technology to streamline the processing of human language-based threat scenario documents, including technical blogs, CTI reports, online threats introduction materials and cyber attack training notes. The goal is to succinctly summarize the attack flow path outlined within such materials via mapping the attack behaviors to the MITRE-ATT&CK Matrix and matching the vulnerabilities to the MITRE-CWE Tree. To achieve this, the program will undertake the following tasks:Identifying Cyber Attack Behaviors: The pr...

Project Design Purpose : This article is the second write up of using the Kypo-CRP for building cyber security CTF challenges or hands on exams environment. I will use the penetration test CTF game “The Secret Laboratory” from Masaryk University’s Spring 2020 semester course PV276 – Seminar on Simulation of Cyber Attacks and as a case study, this article demonstrates two key objectives:How to build and deploy a custom CTF or teaching-assignment sandbox on the KYPO-CRP platform.How to operate within the KYPO-CRP to solve the PV276 Secret Laboratory challenge step-by-step...

Project Design Purpose : This project is designed to create a lightweight, extensible camera-simulation service program that exposes a Motion-JPEG (MJPEG) video stream over HTTP(s) via a Flask web interface for using in the cyber ranges, red/blue exercises, and research where realistic camera endpoints are required without physical hardware. The simulated video stream can be generated from five different type of source:Local physical camera (embedded webcam or USB camera).External live stream (RTSP/HTTP source).Static or rotating image dataset (images loaded from a directory).OS Screen Recordi...

In this case study, I will demonstrate the application of Arm Trust-Zone technology in building a "Trust IoT" device. The primary objective is to safeguard critical data, including encryption keys for communication channels and the IoT firmware attestation program, against potential information leaks and firmware attacks.Project Design: The primary goal of this project is to utilize the Raspberry Pi as the foundation platform for constructing a secure "Trust IoT device", employing ARM Trust-Zone technology to protect critical data such as encryption keys for communication channels and IoT firm...

Have been doing my own startup for sometime and along the way find many things which are not the same as what I have imagined before starting. It's a complete different experience of working in some big companies. Below are some thoughts which I summarized so far and hope they reflect the same thoughts as many other start up builders out there.Execution is the core. Good ideas are certainly important, but without execution in place, no good outcome will follow. Execution means that once the founder and team have agreed on a direction and set a plan, you must truly carry it out—no procras...

Program Design Purpose: The project main objective is to develop a multiplatform Python program obfuscation tool which can easily safeguard the source code for the people who wants to protect their intellectual property rights or manage their software sensitive algorithm. This tool will seamlessly obfuscate and encode the source code into unreadable but Python-interpreter executable bytes data which can be mixed executed with normal python program. Additionally, it will offer a decoder to revert obfuscated byte data back to its original source code. The program comprises three main components:...

If you’ve ever tried to manage 30–40 open tabs in a browser with a widescreen monitor, you likely understand the appeal of turning the tab bar on its side. That’s been the standard in browsers like Microsoft Edge, Vivaldi and others for years. Meanwhile, Chromium-based browsers (including Google Chrome) kept using a horizontal tab strip. Until now.Recent commit activity in Chromium’s review system indicates that the development team is laying serious groundwork for vertical tabs: feature flags, preference keys, layout branching — all the foundational plumbing that...
