  Python PLC Honeypot: Env Deployment And Attack Detection

In the previous article, we introduced the design of Python PLC Honeypot Project, this article will provide detailed step-by-step instructions on how to deploy and use the honeypot system in your environment for detecting potential attacks on OT (Operational Technology) networks. The article includes three main section:   Design of Attack Alert and Notification Function Honeypot deployment: an example deployment of a mixed OT protocol honeypot, consisting of a simple setup with...

  Efficiency of code execution

If you want to optimize your program codes, you need to find their Hotspot, i.e, the codes which are executed most frequently. If you can optimize this portion of codes a bit, you may gain much improvement of your code efficiency. Here I give you three examples about efficiency of code execution.1. PHP's Getter and Setter (From Reddit)This example a quite simple, you can skip it if you want.Consider the code below, we can find it's slower when we use Getter/Setter method to read a member variabl...

  Python PLC Honeypot Project

Program Design Propose : This project aims to develop a sophisticated honeypot system that emulates an OT (Operational Technology) SCADA network environment, bridging Level 1 OT field controller devices (PLCs) with Level 2 control programs, including Human-Machine Interfaces (HMIs). This honeypot will simulate various PLC models from major vendors, such as Schneider and Siemens, while supporting the primary communication protocols Modbus-TCP and Siemens-S7Comm. The system will integrate essenti...

  Applying Large Language Models (LLMs) to Solve Cybersecurity Questions

In this document, we will introduce some test, experiment and analysis conclusion about applying Large Language Models (LLMs) to solve cybersecurity questions. Introduction Large Language Models (LLMs) are increasingly used in education and research for tasks such as analyzing program code error logs, help summarize papers and improving reports. In this project, we aim to evaluate the effectiveness of LLMs in solving cybersecurity-related questions, such as Capture The Flag (CTF) challenges, ...

  When and Where to Use Pointers in Go

When declaring variables in Go, we usually have two syntax options: In some scenarios, pointers; in others, reference; sometimes, either. It’s great to have choices, but it is also confusing sometimes as to which one in which scenario. To be more reasonable in choice-making, I started from pointers, walked through their natures, and summarized some rules in using them in Go. from unsplash, Jordan Ladikos Pointers Go has pointers. A pointer holds the memory address of a ...

  New Unreal Engine 5 and Nvidia Technology in Black Myth: Wukong

In this article, we explore the cutting-edge Unreal Engine 5 and Nvidia GPU technologies used in the highly anticipated AAA game Black Myth: Wukong this year to enhance its game graphical quality. Our insights are based on an interview article of the technical lead of Game Science Interactive Technology, Geekerwan's experimental analysis, and Nvidia's official Black Myth: Wukong showcase featuring the RTX 40xx series. As a software engineer, my perspective may differ from that of a game develop...

  Processing Unicode Data in Python - A Primer to Understand Non-English Data Processing

Introduction: Currently we live in a world where people of diverse cultures/backgrounds use electronic devices to express their ideas, do their daily work that earns them their daily bread, and entertain themselves using content that is created using their own language and so on. Naturally, in order to make all these things happen, any computational instrument, be it a laptop or a desktop computer, or a smartphone, or something else, should be capable enough to serve all of these things in a man...

  Kubernetes Authentication & Authorization 101

If we want to build a system with user modules, Authentication and Authorization are something that we can never ignore, though they could be fuzzy to understand. Authentication (from Greek: αὐθεντικÏŒς authentikos, “real, genuine”, from αὐθέντης authentes, “author”) is the act of proving an assertion, such as the identity of a computer s...

  Popular Golang JSON libraries evaluation

JSON (Javascript Object Notation), a prevailing data exchange format, is widely used in various platforms and languages. Golang, of course, will never miss the support for JSON. And with its own standard library, such as those interfaces like the REST API from the API Service in Kubernetes, it can easily process JSON. Although Go’s library works great, we can still seek those open-source JSON libs in Github to maximize our efficiency. Then the features, performance, applicability of these ...
