    This article presents a complete AWS-based DevSecOps architecture that embeds AI throughout the software delivery lifecycle. Using Amazon Q Developer, CodePipeline, Inspector, EKS, DevOps Guru, Bedrock, Lambda, and Step Functions, the system performs code review, security gating, anomaly detection, AI-assisted incident analysis, and severity-based auto-remediation. Beyond the implementation details, the article argues that modern pipelines should evolve from passive automation systems into active participants in software quality, security, and operational resilience.

  • Why We Built LiveView: Moving FastNetMon from the Terminal to the Operational Surface

    This story was originally published on HackerNoon at: https://hackernoon.com/why-we-built-liveview-moving-fastnetmon-from-the-terminal-to-the-operational-surface.

    This article argues that modern DDoS mitigation is largely an automation problem that has already been solved, but observability remains a challenge. It introduces FastNetMon LiveView as a browser-based interface that provides real-time traffic analytics, attack visibility, historical event analysis, and operational governance capabilities. The core thesis is that automated mitigation systems become more effective when operators can understand, audit, and tune their behavior through shared, visual telemetry rather than relying solely on command-line tools.

    OpenOSINT is an open-source, MCP-native OSINT framework with 14 intelligence tools, an AI-powered interactive REPL, a web UI, and a CLI — all driven by Claude's native tool use API. You type a target in natural language; the agent decides what to investigate, chains the tools, and hands you a structured report. No hallucinated results. Ever.

  • DevSecOps Is Failing Because Security Is Still Being Sold as a Product, Not a Practice

    This story was originally published on HackerNoon at: https://hackernoon.com/devsecops-is-failing-because-security-is-still-being-sold-as-a-product-not-a-practice.


    A security product gives you a tool and a dashboard. A security practice gives you a discipline that gets embedded into how your engineers work every day.

    Discover why DevSecOps is failing to fully integrate security into the development process due to the continued emphasis on selling security as a product rather than promoting it as an ongoing practice. Learn how shifting this mindset can greatly improve the overall security of your organization's software and processes.

  • Post-AI Security: The End of Slow, Static and Periodic Defense

    This story was originally published on HackerNoon at: https://hackernoon.com/post-ai-security-the-end-of-slow-static-and-periodic-defense.


    AI compresses security timelines. Post-AI Security means seeing earlier, fixing faster, exposing less, and governing AI agents with identity and auditability.

    AI does not make security impossible. It makes slow, static and periodic security obsolete. Post-AI Security is the operating model needed when AI agents compress the time between vulnerability discovery, exploitation, remediation and validation. The practical answer is not “buy more AI,” but to see earlier, fix faster and expose less: better inventory, deception, live patching, virtual patching, curated sources, continuous maintenance, SBOMs, agent identity, MCP-aware governance and timeline audits. The future points toward verifiable, sovereign software supply chains built on reproducible builds, attested pipelines and AI-assisted defensive validation.

    grep is one of the most used tools in security work and one of the least understood beyond the basics. This article covers it from the ground up — from a bare search to recursive scanning, context flags, regex modes (BRE, ERE, PCRE), and practical patterns for credential hunting, log analysis, and output parsing. By the end, you will know how to use grep the way security practitioners actually use it, not just how tutorials teach it.
