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. -

fping
High performance ping tool
fping is a program to send ICMP echo probes to network hosts, similar to ping, but much better performing when pinging multiple hosts. fping has a very long history: Roland Schemers did publish a first version of it in 1992 and it has established itself since then as a standard tool for network diagnostics and statistics. There was no official fping release from 2002 until end of 2011. Various patches existed, but were never integrated "upstream". Also, the official maintainer didn't answer emails, so I decided to just step up and take over maintenanceship.To mark this change of maintenance, and avoid confusion, I decided to call it version 3. Besides a new maintainer, fping now also features a completely rewritten main loop implementation which improves performance significantly. The run time is now close to the theoretical time required to send and receive the pings under the specified parameters. -
