Nitro Enclaves Command Line Interface
Tooling for Nitro Enclave management
This repository contains a collection of tools and commands used for managing the lifecycle of enclaves. The Nitro CLI needs to be installed on the parent instance, and it can be used to start, manage, and terminate enclaves. The Nitro Enclaves kernel driver is available in the upstream Linux kernel starting with the v5.10 kernel for x86_64 and starting with the v5.16 kernel for arm64. The codebase from the 'drivers/virt/nitro_enclaves' directory in this GitHub repository is similar to the one merged into the upstream Linux kernel. The enclaves do not have access to a physical disk, just a RAM filesystem. ... -

Osquery
SQL operating system instrumentation and monitoring framework
...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. -

Hubble
Network, Service & Security Observability for Kubernetes using eBPF
...It is built on top of Cilium and eBPF to enable deep visibility into the communication and behavior of services as well as the networking infrastructure in a completely transparent manner. The Linux kernel technology eBPF is enabling visibility into systems and applications at a granularity and efficiency that was not possible before. It does so in a completely transparent way, without requiring the application to change or for the application to hide information. By building on top of Cilium, Hubble can leverage eBPF for visibility. ... -

Kindling
eBPF-based Cloud Native Monitoring Tool
Kindling is an eBPF-based cloud-native monitoring tool, which aims to help users understand the app behavior from kernel to code stack. With trace profiling, we hope the user can understand the application's behavior easily and find the root cause in seconds. Besides trace profiling, Kindling provides an easy way to get an overview of network flows in the Kubernetes environment and many built-in network monitor dashboards like TCP retransmit, DNS, throughput, and TPS. -

systemd
The systemd system and service manager
systemd is a suite of basic building blocks for a Linux system. It provides a system and service manager that runs as PID 1 and starts the rest of the system. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. systemd... -

Syslogd2
High capacity syslog data collection, filtering, and management.
...It is multi-threaded, scalable and versatile with features designed for both network and host managers. Each Syslogd2 binary is customized from a set of over 20 features at compile-time. It can support input from text files, named-pipes, Linux kernel and user-defined Linux and (both IPv4 and IPv6) IP sockets (both UDP and TCP). It provides a pre-loadable name-cache that can replace DNS services for host-name resolution. Syslogd2 easy-to-use filters use string-matching to select messages which can then be modified, dropped, kept or re-routed (changed to new facilities). Filters are applied to inputs, outputs or both to control msg-routing and network load. ... -

openPOWERLINK
An Open Source POWERLINK Stack
...With version 2.0, the source code has been cleanly split into an application-oriented user library and a time-critical stack driver. The latter may be moved to a dedicated communication processor or into a kernel module to deliver enhanced performance while still keeping the API in user space. A full documentation of the stack is available on the web site: http://openpowerlink.sourceforge.net The following page can be used to report a security vulnerability: https://sourceforge.net/p/openpowerlink/discussion/ -

xdp
Package xdp allows one to use XDP sockets
Package github /asavie/xdp allows one to use XDP sockets from the Go programming language. With the default UDP payload size of 1400 bytes, running on Linux kernel 5.1.20, on a tg3 (so no native XDP support) gigabit NIC, sendudp does around 980 Mb/s, so practically line rate. TL;DR: in the same environment, sending a pre-generated DNS query using an ordinary UDP socket yield around 30 MiB/s whereas sending it using the senddnsqueries example program yields around 77 MiB/s. Connecting a PC with Intel Core i7-7700 CPU running Linux kernel 5.0.17 and igb driver to a laptop with Intel Core i7-5600U CPU running Linux kernel 5.0.9 with e1000e with a cat 5E gigabit ethernet cable. -
