OSQuery VS falco

Perhaps the OP means OsQuery: https://github.com/osquery/osquery

OsQuery is an SQLite extension consisting of hundreds of virtual tables

There's at least one open data quality issue for `process_open_sockets` on macOS[1]. It's a few years old however and, if you aren't seeing that casting error, you probably aren't hitting it. But that's a good example of the kind of debt that's been built up over time.

(In terms of general purpose/flexible tooling, I'm not aware of a close replacement for osquery.)

The largest we have successfully deployed is on the OSQuery schema https://osquery.io/ which is 277 tables and lots of business context (malwares, vulnerabilities, Windows registry keys, etc).

From a self hosted standpoint OSQuery or Wazuh are your best bets for monitoring USB devices. Windows makes blocking really challenging and I’m not aware of any “free” solutions that attempt it.

Configure auditd to monitor host activity: https://izyknows.medium.com/linux-auditd-for-threat-detection-d06c8b941505 or osquery: https://osquery.io/ (or similar software: filebeat for example).

OS Query : Easily ask questions about your Linux, Windows, and macOS infrastructure

Osquery + Fleet. https://osquery.io/ https://fleetdm.com/, using the two allows you to build a query to answer what ever questions you (or an auditor) might have about your environment.

Like snort, but looks at system calls.

From one noob to another - I had a lot of fun setting up Falco (https://falco.org) and creating custom policies & alerts.

Falco is a well-known open source security solution originally created by Sysdig. It’s a CNCF incubating project and one of the few (as far as I can tell) options on this list that uses eBPF to scan for vulnerabilities.

Use some kind of SIEM or Falco to alert you to threats (you can't stop them, but a human can always intervene)

Falco, is a security project that can help you detect threats from within your cluster.

https://falco.org/ is a security-focused monitoring and alerting with an eBPF option

On the cgo side I want to highlight two talks: one from Loris Cro about dealing with cross-complition difficulties, that the usage of cgo brings, using the Zig language and the other from Jason Dellaluce and Leonardo Grasso about how to extend Falco, a Kubernetes threat detection engine, which is written in C++, with plugins written in Go, explaining the challenges of integrating cgo in both C and Go.
