Understanding Credly Badges and the “Explain‑to‑Me” Feature in Practical DevSecOps Courses

Understanding Credly Badges and the “Explain‑to‑Me” Feature in Practical DevSecOps Courses Introduction When you start a Practical DevSecOps course, two visual cues help you track progress and deepen learning: Credly digital badges and the “Explain‑to‑Me” icon ( ? ) that appears next to code snippets. Both tools are designed to celebrate achievements, showcase your expertise, and turn complex commands into bite‑size lessons. This article explains exactly what you’ll see in Credly, how to use the badge‑sharing options, and how the “Explain‑to‑Me” feature works inside the learning environment. 1. What a Credly Badge Looks Like and How to Use It 1.1 Visual preview of a Credly badge - Badge shape – A compact, circular or shield‑shaped graphic that includes the Practical DevSecOps logo, the specific certification name (e.g., “Certified DevSecOps Professional”), and the date you earned it. Tip: In most browsers you’ll see a subtle “Verified by Credly” badge corner that confirms authenticity. 1.2 Accessing your badge 1. Receive a notification – After pass a certification exam, you’ll get an email to accept your Credly badge 2. Open the badge – Clicking the button takes you to Credly’s web portal where the badge is displayed in full size. 3. Explore badge actions – Below the badge you’ll find a row of icons: - Share – Post directly to LinkedIn, Twitter, Facebook, or embed on a personal website. - Download – Save a PNG or SVG version for a résumé or portfolio. - Verify – Copy a public verification link that employers can click to confirm the credential. 1.3 Sharing best practices - LinkedIn – Add a short caption that highlights the specific skill you earned (e.g., “Just earned the Practical DevSecOps Professional badge – now proficient in secure CI/CD pipelines”). - Twitter – Use hashtags like #DevSecOps, #Credly, and #ContinuousLearning to increase visibility. - Personal website – Embed the badge using the provided HTML snippet; this creates a live verification widget that updates automatically if the badge is renewed. 2. The “Explain‑to‑Me” ( ? ) Icon in Code Snippets 2.1 Purpose of the question‑mark icon The small question‑mark that appears next to a command or configuration line is not a typo—it’s an interactive learning aid called Explain‑to‑Me. Its goal is to: - Provide a concise, plain‑language description of what the command does. - Reduce the need to switch tabs or search external documentation. - Support learners of all experience levels, from beginners to seasoned security engineers. 2.2 How it works | Action | Result | |--------|--------| | Click the ? icon | A pop‑up window or inline tooltip appears, showing a short paragraph (≈ 2‑3 sentences) that explains the command’s purpose, typical use cases, and any important flags. | | Hover (desktop) or tap (mobile) | A preview tooltip shows a one‑sentence summary. | | Close the pop‑up | The tooltip disappears, returning you to the code view without losing your place. | Example: In a Dockerfile you see RUN apt‑get update && apt‑get install -y curl ?. Clicking the ? displays: “Updates the package index and installs the curl utility, which is used for transferring data with URLs. The -y flag automatically answers ‘yes’ to prompts.” 2.3 When to use Explain‑to‑Me - First‑time exposure – If you’ve never seen a command before, the tooltip gives you a quick mental model. - Exam preparation – Review the explanations to reinforce key concepts before a certification test. - Reference while coding – While building a pipeline, the pop‑ups act as an on‑the‑fly cheat sheet, keeping you focused on the task. 3. Practical Scenarios Scenario 1: Using Explain‑to‑Me while debugging a pipeline 1. Open the CI/CD YAML file in the Practical DevSecOps lab. 2. Spot the line - script: npm audit ?. 3. Click the ? to read: “Runs npm audit to identify known vulnerabilities in Node.js dependencies. Returns a report with severity levels.” 4. Adjust the script based on the explanation (e.g., add --audit-level=high). 4. Common Questions Q1: Do Credly badges expire? No. Once issued, a badge remains valid indefinitely. If the underlying certification is updated, you may receive a refreshed badge with a new issuance date. Q2: Are the explanations language‑specific? The tool currently only support english language. Q3: Is the badge shareable outside Credly? Absolutely. You can download the image file or use the embed code to place the badge on any website, blog, or internal portal. Conclusion Credly badges give you a portable, verifiable record of your DevSecOps achievements, while the “Explain‑to‑Me” ? icon turns every code snippet into a mini‑tutor. Together, they create a seamless learning loop: you earn a badge, showcase it, and use built‑in explanations to deepen your expertise. Embrace both features to accelerate your career, build a compelling professional profile, and master the secure development practices that modern organizations demand.

Getting Started with Practical DevSecOps: Course Filters, and Account FAQs

1. Organizing Your Learning Path with Course Filters Practical DevSecOps courses contain a mix of hands‑on labs, videos, quizzes, readings, and feedback forms. The filter panel on the dashboard lets you view exactly what you need, when you need it. 1.1. Filter by Task Type | Task Type | What It Contains | Typical Use | |-----------|------------------|-------------| | Hands‑on Exercise | Interactive labs and command‑line tasks | Practice real‑world scenarios | | Video | Recorded lectures or demos | Visual learning, concept review | | Quiz | Multiple‑choice or short‑answer assessments | Test knowledge retention | | Reading Material | PDFs, articles, or reference guides | Deep‑dive theory | How to apply: Click the Task Type dropdown and select one or more categories. The list updates instantly, showing only the relevant items. 1.2. Filter by Priority - Mandatory – Must be completed to earn the certification. - Optional – Helpful but not required; good for extra practice. Tip: Prioritize mandatory tasks early to stay on track for the certification deadline. 1.3. Filter by Status | Status | Meaning | |--------|---------| | Not Started | Not started or still pending | | In Progress | Currently being worked on | | Completed | Finished successfully | Example Workflow: 1. Select Not Started to see what’s left. 2. Switch to In Progress to resume a paused lab. 3. Use Completed to verify you’ve met all requirements before the final exam. 2. Why My Courses Aren’t Visible? (Payment Shows “Pending”) If the dashboard shows no courses and your payment status reads Pending, follow these steps: 1. Confirm Payment Confirmation – Verify that the transaction has cleared in your bank or payment gateway. 2. Schedule the Course – Log in to the members portal at https://members.practical-devsecops.training. 3. Select a Start Date – Choose an available slot for each enrolled course and click Schedule. Once scheduled, the courses will appear automatically on your dashboard based on your scheduled time. If the issue persists, you can email us at training@practical-devsecops.com 3. ID Verification: Non‑English Names Are Accepted During enrollment you may upload an ID card that contains your name in a language other than English (e.g., Azerbaijani script). This is not a problem: - Our verification system supports Unicode characters, so names in Cyrillic, Arabic, Azerbaijani, or any other script are accepted. - The only requirement is that the ID is clear, legible, and matches the personal details you provided during registration. If you encounter an error message, contact the live agent with a screenshot of the error message. 5. Common Questions & Quick Tips | Question | Quick Answer | |----------|--------------| | Can I ask the bot for resources outside the current lab? | Yes – specify the topic (e.g., “Explain OWASP Top 10”) and the bot will share links or summaries. | | Do filters affect my progress tracking? | No. Filters only change the view; your progress data remains unchanged. | | What if I miss a scheduled start date? | Reschedule from the members portal; you can choose any future slot without penalty. | | How long does “Explain to Me” take? | Usually under 5 seconds; the response appears directly beneath the command block. | | Is there a way to export my completed tasks? | Use the Download Report button on the dashboard to get a CSV of all tasks and their statuses. | Pro Tip: Combine filters to narrow down your view dramatically. For example, select Hands‑on Exercise + Mandatory + Not Started to see exactly which critical labs you still need to finish. By mastering these tools, you’ll spend less time navigating the platform and more time building real‑world DevSecOps expertise. Happy learning!4

Open Source Threat Modeling Tools: A Practical Guide for DevSecOps Beginners

Open Source Threat Modeling Tools: A Practical Guide for DevSecOps Beginners Threat modeling is a cornerstone of any DevSecOps program—it helps you anticipate security risks, prioritize mitigations, and communicate findings to stakeholders. With a growing ecosystem of free, community‑maintained utilities, you don’t need an expensive commercial suite to get started. This article walks you through the key considerations when selecting an open‑source threat‑modeling tool, highlights the most widely‑used options, and shows how to integrate a tool into your first security‑by‑design workflow. Why Choose an Open‑Source Threat Modeling Tool? | Benefit | What It Means for You | |--------|-----------------------| | Cost‑effective | No licensing fees; you can spin up as many instances as needed. | | Transparency | Source code is visible, so you can verify the methodology and extend it. | | Community support | Active contributors share templates, plugins, and best‑practice guides. | | Flexibility | Easily integrate with CI/CD pipelines, issue trackers, or documentation generators. | Open‑source tools are especially attractive for teams that are just beginning their DevSecOps journey, as they allow rapid experimentation without a large budget commitment. Factors to Evaluate Before Picking a Tool 1. Intended Outcome - Risk register: Do you need a structured list of threats with severity scores? - Architecture diagrams: Are visual representations a priority? - Compliance mapping: Must the tool align threats with standards like ISO 27001 or NIST 800‑53? 2. Time & Skill Investment - Some tools are drag‑and‑drop (e.g., Threat Dragon) and require little training. - Others are script‑oriented (e.g., pyTM) and assume familiarity with Python or Markdown. 3. Scope of Modeling - Application‑level: Focus on APIs, microservices, or UI flows. - Infrastructure‑level: Model cloud resources, network topology, or IaC templates. 4. Integration Needs - Does the tool export to JSON, CSV, or STIX for downstream analysis? - Can it be triggered from GitHub Actions, GitLab CI, or Jenkins? 5. Community Activity - Look at recent commits, open issues, and the size of the contributor base. A lively repo usually means quicker bug fixes and new features. Popular Open‑Source Threat Modeling Tools Below is a curated snapshot of the most actively maintained utilities (the full list lives at the Awesome Threat Modeling repository). 1. Threat Dragon (OWASP) - Type: Web‑based UI + desktop (Electron) - Strengths: Intuitive drag‑and‑drop canvas, built‑in STRIDE templates, export to JSON or PDF. - Best For: Teams that value visual diagrams and quick onboarding. 2. Microsoft Threat Modeling Tool (Free, not fully open source) - Type: Windows desktop app - Strengths: Rich data‑flow modeling, automatic threat generation, integrates with Azure DevOps. - Best For: Organizations already invested in Microsoft ecosystems. 3. pyTM - Type: Python library + CLI - Strengths: Scriptable threat generation, Markdown output, easy to embed in CI pipelines. - Best For: Developers comfortable with code‑first approaches. 4. SecuriCAD (Community Edition) - Type: Simulation‑based modeling (limited free tier) - Strengths: Quantitative risk scores, attack‑path simulation. - Best For: Teams that need deeper quantitative analysis without a commercial license. 5. ThreatSpec - Type: DSL (Domain‑Specific Language) + Ruby gem - Strengths: Write threat models as code, version‑control friendly, integrates with Git. - Best For: DevSecOps pipelines that treat security artifacts like any other source code. Getting Started: A Step‑by‑Step Example with Threat Dragon 1. Install - Visit the Threat Dragon releases page and download the appropriate installer (Windows, macOS, or Linux). 2. Create a New Model - Choose “Create New Model” → select the STRIDE template. - Sketch your system’s data flow: external users → API gateway → microservice → database. 3. Generate Threats - Click “Auto‑Generate Threats”. The tool will list STRIDE‑derived threats for each component (e.g., Spoofing on the API gateway). 4. Prioritize - Assign Likelihood and Impact scores (Low/Medium/High). - The tool automatically calculates a Risk Rating. 5. Export & Share - Export the model as a PDF for stakeholder review or as JSON for automated ingestion into a ticketing system (e.g., Jira). 6. Integrate with CI - Store the exported JSON in your repository. - Add a GitHub Action that validates the JSON schema on every pull request, ensuring the model stays in sync with code changes. Common Questions | Question | Answer | |----------|--------| | Do I need a diagramming tool in addition to the threat‑modeling software? | Most open‑source tools include built‑in diagram editors. If you prefer a separate diagramming suite (e.g., draw.io), you can import/export SVG files. | | Can I use these tools for cloud‑native environments? | Yes. Look for plugins that ingest Terraform or AWS CloudFormation files (e.g., ThreatSpec’s IaC parser). | | How do I keep the threat model up‑to‑date? | Treat the model as source code: store it in version control, review changes during code reviews, and automate validation in CI pipelines. | | Is there a learning curve? | Tools like Threat Dragon require minimal training (<1 hour). Code‑first tools (pyTM, ThreatSpec) need basic scripting knowledge but pay off with repeatable automation. | Tips for Successful Open‑Source Threat Modeling - Start Small: Model a single high‑risk service before expanding to the whole architecture. - Leverage Templates: Use STRIDE, PASTA, or CVSS templates to ensure consistent threat identification. - Automate Repetitive Tasks: Export models to JSON and feed them into issue‑trackers or security dashboards. - Engage the Community: Contribute bug fixes or new templates back to the project—this improves the tool and builds your credibility. - Document Decisions: Capture why a threat was accepted, mitigated, or transferred; this documentation is invaluable for audits and future teams. Take the Next Step Open‑source threat modeling empowers DevSecOps teams to embed security early, iterate quickly, and stay budget‑conscious. Pick a tool that matches your team’s skill set, integrate it into your CI/CD workflow, and make threat modeling a living part of your development lifecycle. Happy modeling!

Linux Fundamentals for DevSecOps: Shebang, Filesystem, PATH, Links, and Prompt

Linux Fundamentals for DevSecOps: Shebang, Filesystem, PATH, Links, and Prompt Welcome to the first step of your Practical DevSecOps journey! Before you can automate security checks, build pipelines, or write secure scripts, you need a solid grasp of the Linux environment that underpins every DevSecOps tool. This article demystifies the most frequently encountered concepts—shebang, filesystem hierarchy, PATH variable, hard & symbolic links, and the command prompt—and provides clear examples you can try right away. 1. The Shebang (#!) – Telling Linux Which Interpreter to Use What is a shebang? A line that starts with #! (pronounced “hash‑bang”) at the very top of a script is both a comment and an instruction. It tells the kernel which interpreter should execute the file. #!/bin/bash # This is a comment for humans echo "Hello, DevSecOps!" - #!/bin/bash points to the Bash binary located in /bin. - Everything after # on that line is ignored by the interpreter, so it also works as a regular comment. Why it matters in DevSecOps - Guarantees consistent execution across different environments (e.g., CI runners, containers). - Prevents “script not found” errors when the default shell isn’t Bash. Quick test: Create a file named hello.sh, paste the snippet above, make it executable (chmod +x hello.sh), and run ./hello.sh. You should see Hello, DevSecOps!. 2. Navigating the Linux Filesystem Linux organizes files in a single rooted tree (/). Understanding where executables, libraries, and configuration files live is essential for troubleshooting and for placing your own tools. | Directory | Typical Contents | When to use it | |-----------|------------------|----------------| | /bin | Essential user binaries (e.g., ls, cat) | System‑wide commands required for boot | | /usr/bin | Most user commands (e.g., git, vim) | General purpose utilities | | /usr/local/bin | User‑installed executables (custom scripts, third‑party tools) | Ideal location for tools you compile or download yourself | | /sbin & /usr/sbin | System administration binaries (e.g., ifconfig) | Usually accessed by root | | /opt | Optional add‑on software packages | Large third‑party applications | Practical scenario You’ve just compiled a security scanner from source. Place the binary in /usr/local/bin so it’s available to every user without cluttering system directories. sudo cp myscanner /usr/local/bin/ Now you can run myscanner from any directory. 3. The PATH Environment Variable What is PATH? PATH is a colon‑separated list of directories that the shell searches when you type a command without a full path. echo $PATH # Example output: # /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin How it works When you type git, the shell checks each directory in $PATH in order. The first matching executable is run. Adding a custom directory to PATH If you store scripts in ~/bin, make sure the shell can find them: # Add to current session export PATH=$HOME/bin:$PATH # Persist across logins (add to ~/.bashrc or ~/.profile) echo 'export PATH=$HOME/bin:$PATH' >> ~/.bashrc source ~/.bashrc Why PATH matters for DevSecOps - Enables you to invoke tools (e.g., trivy, kube-score) from any location in CI pipelines. - Avoids hard‑coding absolute paths in scripts, making them portable. 4. Links: Hard vs. Symbolic Linux provides two ways to reference the same data: hard links and symbolic (soft) links. Hard Links - Create another directory entry that points directly to the same inode (the actual data on disk). - No separate file; deleting one link does not delete the data as long as another link exists. - Cannot span different filesystems or reference directories. # Create a hard link ln original.txt hardcopy.txt # Verify they share the same inode ls -i original.txt hardcopy.txt Symbolic Links - A special file that contains a pathname to another file or directory. - Can cross filesystem boundaries and point to directories. - If the target is removed, the symlink becomes “dangling”. # Create a symbolic link ln -s /usr/local/bin/myscanner /usr/bin/myscanner # Show where it points ls -l /usr/bin/myscanner When to use which? - Hard links – Rarely needed in DevSecOps; useful for backup scripts where you want multiple names for the same file without extra storage. - Symbolic links – Ideal for versioned tools (/opt/tool-1.2/bin/tool -> /opt/tool-1.2.3/bin/tool) or for creating shortcuts in $PATH. 5. Customizing the Command Prompt A clear prompt helps you recognize the current user, host, and directory—especially when juggling multiple terminals. Basic PS1 example export PS1='\u@\h:\w\$ ' # Result: devuser@myhost:/home/devuser$ - \u – username - \h – hostname (short) - \w – current working directory - \$ – shows # for root, $ for normal users Add the line to ~/.bashrc to make it permanent. Prompt tip for DevSecOps Include the active virtual environment or Git branch to avoid committing from the wrong context: export PS1='[\u@\h \W$(git branch 2>/dev/null | grep "^*" | cut -d " " -f2)]\$ ' 6. Common Questions & Tips | Issue | Likely Cause | Fix | |-------|--------------|-----| | Prompt shows ># instead of /# after typing a command | You typed cd .. but didn’t press Enter or the shell is waiting for a closing quote | Press Enter or complete the command. | | #!/bin/bash appears as # only in the editor | The editor is displaying the line as a comment; the shebang is still functional | Verify with head -1 script.sh to see the raw line. | | Command not found even though binary exists in /usr/local/bin | /usr/local/bin not in $PATH | Add it to PATH as shown in Section 3. | | Hard link fails with “Invalid cross‑device link” | Source and target are on different mounted filesystems | Use a symbolic link (ln -s) instead. | Quick Checklist Before Running a Lab 1. Shebang – First line starts with #!/bin/bash (or appropriate interpreter). 2. Executable Permission – Run chmod +x script.sh. 3. PATH – Verify the tool’s directory is in $PATH. 4. Prompt – Ensure you’re at the expected location (/# for root, $ for normal user). 5. Links – Use ls -l to confirm symlinks point where you expect. 7. Wrap‑Up Mastering these Linux fundamentals—shebang, filesystem layout, PATH, linking mechanisms, and prompt customization—lays a reliable foundation for every DevSecOps task, from writing secure automation scripts to configuring CI/CD runners. Keep this guide handy, experiment with the examples, and you’ll move through the Practical DevSecOps courses with confidence. Happy hacking!

certified threat modeling professional (CTMP)

certified threat modeling professional (CTMP) is Learn how to use threat modeling in the modern DevOps organizations Common Question: Q1: Is the Threat Modeling focused on every sort of system? A: Threat Modeling is a concept that is not limited to just software. You can threat model your house, your car, an electronic voting systems, Elections Operations, and many other things. So, is threat modeling focussed just for software? In fact, Threat modeling methodologies like STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege) are still applicable to non-web applications/software.  You can adapt them to the specific context of your application/software. Q2: What's good for PCI certification? A: Tools find threats, and categorize them in to various standard mappings. There are plenty of tools discussed in the course through lectures, and hands on. When you are at the end of the course, you should have a better idea of the choices you want to make. If not, kindly post back here, we will assist you. Q3: How can I integrate the process of threat modeling into our pipeline? A: Here's a brief explanation: - CI/CD is about automating the building, testing, and deploying of your application. - Threat Modeling is a proactive security practice that identifies potential vulnerabilities in your application. While CI/CD itself doesn't directly perform threat modeling, it can automate certain aspects and trigger security checks based on your threat model. For example: - Integrate SAST (Static Application Security Testing) tools that can flag potential security issues in the code based on common coding vulnerabilities. - E.g., Nikto, SSlyze, Nmap. - Integrate DAST (Dynamic Application Security Testing) tools that can scan your application for vulnerabilities while it's running. - E.g., OWASP ZAP. We cover more of these practices in our CDP course. In summary: - Identifying potential threats is the responsibility of the threat modeling team. - Implementing security practices and integrating scanning tools into the pipeline is the responsibility of the DevOps team. - Addressing and fixing vulnerabilities discovered during the scanning process is the responsibility of the development team.
