GitHub Enhances Security with Trusted Publishing and CodeQL

If you run or maintain an open source software project and have public repos especially on GitHub, please take this seriously 👇🏾

🔐 How secure are your GitHub Actions workflows and software supply chain today? GitHub includes a range of built‑in security features that you can enable across your SDLC, many teams just aren’t using them to their full potential. We’ve published practical steps you can apply today, along with a roadmap of security capabilities coming next, to help secure the open‑source supply chain across GitHub. 🔗 https://lnkd.in/gUattvvh

GitHub should do more than recommend. They could use their resources to: - pin all actions to their current resolved sha via dependabot, if active (prevents hidden downgrades) - only allow mutable tags if people opt into it (secure by default) - fail workflows if unpinned and config not present (secure by default) - invest in tooling to make docs show real shas (model behavior)

🚨 The 500,000-Line Mistake: Why Even Giants Fail at Git Anthropic just gave the tech world a masterclass in how fragile security really is. No sophisticated hacking. No zero-day exploits. Just a simple packaging error. 500,000 lines of Claude Code’s internal source code were exposed because of a source map file. 💡 The Automation Paradox In our race to "Automate Everything," we’ve created a massive blind spot. Our CI/CD pipelines, npm publishing, and Docker builds are only as secure as our configuration files. One missing line in a .gitignore can effectively hand over your internal architecture to the public. 🔧 The "Harmless" Push We’ve all done it: git add . git commit -m "fixing bugs" git push origin main It feels productive until you realize a .env file or a /dist folder containing source maps was tagged along for the ride. 📂 Where the Leak Happens Most "leaks" aren't backdoors,they are open windows. Check your .gitignore right now for these often-missed culprits: *.map (Source maps that reconstruct your code) .env (Secrets, API keys, DB strings) *.log (Internal paths and user data) backup/ or tmp/ (Last-minute manual saves) #DevOps #Git #CyberSecurity #CloudEngineering #Azure #Linux #SRE #CodingLife

Just had a highly productive hands-on session diving into the core concepts of Docker! 🐳💻 Instead of just reading the theory, I spent some time directly in the terminal experimenting with containers and exploring how they work under the hood. Here is a quick breakdown of what I accomplished today: 🔍 Explored the CLI: Started by digging into the Docker CLI using --help to understand the vast array of commands available for images and containers. 📥 Pulled Images: Successfully pulled the official nginx:latest image from Docker Hub. 🚀 Container Lifecycle: Experimented with running containers in the foreground, stopping them gracefully, and then running an Nginx container in detached mode (-d) with a custom name (--name hitesh-nginx). 🕵️♂️ Inside the Matrix: Used docker exec -it hitesh-nginx bash to jump straight into the running container's shell. 📂 Navigating the OS: Navigated through the internal Linux file system to locate the default web root directory for Nginx (/usr/share/nginx/html). Even made the classic developer mistake of trying to cd into the index.html file before realizing my typo! 😂 Every time I get hands-on with Docker, I'm amazed by how lightweight and isolated these containerized environments are. Building muscle memory in the terminal is definitely the best way to learn. #Docker #DevOps #LearningInPublic #Nginx #Linux #TechJourney #SoftwareEngineering DevOps Insiders

📚 Git & GitHub Series — Part 7: .gitignore (Protect Your Project) 🚨 The Mistake That Breaks Projects You push your code to GitHub… Everything looks fine… until: ❌ Your API keys are exposed ❌ Your passwords are public ❌ Your project is full of unnecessary files (node_modules, logs, etc.) 💥 Now your app is at risk. 🛑 What is .gitignore? 👉 .gitignore is a file where you tell Git: “Ignore these files. Do NOT track or upload them.” 🎯 Why Do We Use It? Because not everything should go to GitHub: ❌ Things you should NOT push: node_modules/ .env files (secrets 🔐) Logs (*.log) OS files (.DS_Store) Build files (dist/, bin/) ⚙️ Example node_modules/ .env *.log dist/ 📌 Git will ignore all these files completely 🚨 SECURITY ALERT (Very Important) ❌ NEVER do this: const apiKey = "123456SECRET"; inside config.js and push it ❌ ✅ Best Practice 👉 Put sensitive data in a .env file: API_KEY=123456SECRET Then add .env to .gitignore: .env 🔐 Why This Matters Keeps your secrets safe Prevents leaks on GitHub Protects your app from attacks 📌 Once something is pushed, it’s VERY hard to remove completely 🧠 Pro Tip If you already pushed sensitive data: 👉 Change the keys immediately 👉 Then remove them from history (advanced) #Git #GitHub #VersionControl #SoftwareDevelopment #Programming #Developers #WebDevelopment #Coding #Tech #CyberSecurity #LearnToCode #FullStack #SoftwareEngineering #DevTips

GitHub made a decision that should alarm every company with proprietary code. And most of the industry hasn't noticed yet. Starting April 24, 2026, GitHub will use Copilot interaction data to train its AI models -- by default, unless individual users opt out. I've seen this framed as a privacy story. It isn't. It's an IP story, and it's far more serious. Here's what actually happens when GitHub trains on your code: Your proprietary logic, your architecture decisions, your internal patterns and business rules get baked into a model that serves MILLIONS of developers worldwide. Including your competitors. A developer on the other side of the world could receive a Copilot suggestion shaped by your code and have absolutely no idea where it came from. Neither would you. There is no audit trail. There is no way to identify what was exposed. There is no way to reverse it once the model is trained. The recipient doesn't even know they received your IP. And you have no recourse. This is silent, untraceable, irreversible diffusion of your company's intellectual property into the global developer ecosystem. That is not hyperbole. That is the stated purpose of the policy. Now add this: the opt-out is per individual user. There is no organization-level control on Free, Pro, or Pro+ plans. No admin dashboard. No audit log. No way to verify or enforce compliance across your team. If even one developer -- or contractor, or new hire -- doesn't opt out, their Copilot interactions (and all the code Copilot can see in that moment) are in scope. For companies in regulated industries, this isn't just alarming. It potentially conflicts with GDPR, HIPAA, SOC 2, ISO 27001, and client confidentiality agreements. "We told everyone to opt out" is not a compliance posture. GitHub announced this with less than 30 days notice. This deserves a massive industry response. If your company uses Copilot Free, Pro, or Pro+, you need to act before April 24. And if you're in a regulated industry, you need your legal team involved today. Opt out: https://lnkd.in/efPY7skt → Privacy But more importantly: demand better from platforms that hold your most sensitive assets. #GitHub #Copilot #IntellectualProperty #DataPrivacy #Compliance #CyberSecurity #SoftwareDevelopment #GDPR #HIPAA

Just shipped a GitHub Action that adds SBOM scanning to any CI/CD pipeline in 6 lines of YAML.  Every push and PR gets scanned automatically:  - Auto-detects your manifest (package.json, requirements.txt, go.mod, Cargo.toml, pom.xml -- 15 types)  - Generates a CycloneDX SBOM  - Scans with dual vulnerability databases (Grype + OSV)  - Exports SARIF to GitHub Code Scanning  - Shows a scan summary right in the Actions tab  You can set it to block merges if critical vulns are found:  - uses: sbomly/scan-action@v1   with:    api-key: ${{ secrets.SBOMLY_API_KEY }}    fail-on-severity: critical  Every scan also includes regulatory compliance scoring (NTIA, EU CRA, EO 14028), end-of-life detection, and EPSS  exploit probability -- all in under 60 seconds.  The scan ran on one of my TypeScript projects: 292 components, 5 vulnerabilities identified, full SARIF uploaded,  summary table in the Actions tab. No config beyond the 6 lines.  Free to try. GitHub Marketplace: https://lnkd.in/gaHhAw9r  #SBOM #GitHubActions #DevSecOps #SupplyChainSecurity #BuildInPublic

After using GitHub Copilot CLI daily, I've identified 5 slash commands that have significantly improved my development workflow. Here's what every developer should know: → /mcp - Manage Model Context Protocol servers directly from your terminal. Add new MCPs or list existing ones without leaving your flow. → /skills - Browse and add skills to extend your CLI capabilities. Perfect for customizing your development environment. → /agent - Create and manage custom agents for specialized tasks. → /diff - Review file changes and leave inline comments. A cleaner way to track modifications. → /terminal setup - A one-time configuration to enable shift+enter functionality. The real game-changer? The /pr commands. /pr create handles all the due diligence: ensuring your branch is up to date, managing prerequisites, and automating the entire pull request process. /pr fix takes it further by checking CI status and automatically addressing failures and merge conflicts. I initially underestimated these PR commands, but they've become indispensable for maintaining velocity without sacrificing code quality.
