cloud-custodian VS OSQuery

> The best optimization is simply shutting things off

This is the way.

A similar idea has been bouncing around in my mind for a while now. An ideal, turnkey system would do the following:

- Execute via Lambda (serverless).

- Support automated startup and shutdown of various AWS resources on a schedule influenced by specially formatted tags.

- Enable resources to be brought back up out of schedule when demand dictates.

- Operate as a TCP/HTTP proxy that can delay clients so that a given service can be started when it is dormant or, even better, the service isn't serverless but you want it to be. This can't work for everything, but perhaps enough things such that the need to run always on services is reduced.

Cloud Custodian [1] can purportedly do some of this, but I've been reluctant to learn yet another YAML-based DSL to use it.

So this is my "make things designed to be always-on serverless instead" project and the work AWS has done to make Java apps function on Lambda keeps me thinking about the potential to take things that 1) have a relatively long startup time and 2) are designed to be long running service loops, and find a way to force them into the serverless execution model.

Goal was to clear up anything old and set us up to rotate keys in use. Why did I do it in the end of December? It was a quarterly goal and I learned to push those across the line if I wanted a good review. Great incentive, that one. I used Cloud Custodian for this. It has a terrible bug where the code says you'll be acting on days since the key was used but actually is reading days since it was created.

What is wrong with https://github.com/cloud-custodian/cloud-custodian?

You can start reading about it here.

Use a tool like this https://cloudcustodian.io/ to manage instance on/off hours or go fargate.

Certs aside, there are some great compliance tools out there that you might want to become familiar with. Here is one that comes to mind (is open-source): https://cloudcustodian.io/

I'd use a combination of Cloudcustodian for start/stop scheduling and Apprise for notifications.

Cloud custodian is a good utility if config rules doesn’t satisfy your needs. It’s also cross platform.

AWS Security with open source – Cloud Custodian is a Cloud Security Posture Management (CSPM) tool. CSPM tools evaluate your cloud configuration and identify common configuration mistakes. They also monitor cloud logs to detect threats and configuration changes.

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.
