    Runtime Security Enforcement System

    KubeArmor is a runtime Kubernetes security engine. It uses eBPF and Linux Security Modules(LSM) for fortifying workloads based on Cloud Containers, IoT/Edge, and 5G networks. It enforces policy-based controls. KubeArmor is a runtime Kubernetes security engine. It uses eBPF and Linux Security Modules(LSM) for fortifying workloads based on Cloud Containers, IoT/Edge, and 5G networks. It enforces policy-based controls. KubeArmor lessens the attack surface on pods, containers, and virtual machines. For inline mitigation, it uses Linux Security Modules (LSMs) like AppArmor, BPF-LSM, and SELinux to provide security without changing the pod or container or without host-level adjustments. KubeArmor simplifies their intricacies and makes enforcing policy simple. It functions as a non-privileged daemonset and has host, pod, and container monitoring capabilities.

    Osquery

    Osquery

    SQL operating system instrumentation and monitoring framework

    Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive. Osquery exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.Osquery queries your devices like a database. Osquery uses basic SQL commands to leverage a relational data-model to describe a device. Frequently, attackers will leave a malicious process running but delete the original binary on disk. This query returns any process whose original binary has been deleted, which could be an indicator of a suspicious process.

    StatiCrypt

    StatiCrypt

    Password protect a static HTML page

    StatiCrypt uses AES-256 and WebCrypto to encrypt your HTML file with your long password and return a static page including a password prompt and the javascript decryption logic that you can safely upload anywhere (see what the page looks like). This means you can password protect the content of your public static HTML file, without any back-end - serving it over Netlify, GitHub pages, etc. You can encrypt a file online in your browser (client side). StatiCrypt uses WebCrypto to generate a static, password protected page that can be decrypted in-browser. You can then just send or upload the generated page to a place serving static content (github pages, for example) and you're done: the page will prompt users for a password, and the javascript will decrypt and load your HTML, all done in the browser.
