System Administration: Week 12: System Security II: From the Attack Life Cycle to Zero Trust

In this video, we continue approaching System Security from an attacker's point of view by understanding their common processes, following the Attack Life Cycle and then identifying how our defenses, supported by the Zero Trust model, can interrupt each stage.

Defense in Depth Security is like an onion: the more layers you peel away, the more it stinks. Never assume any one protection mechanism is sufficient. Always assume the other protections you deployed can be circumvented or broken.

Alt...

Zero Trust Core concept: the simple assumption of a compromised or hostile environment. -> transport encryption -> mutual authentication -> explicit authorization -> time limited grants -> identity based

Shipped two releases of ansible-jailexec today. An Ansible connection plugin that runs tasks inside FreeBSD jails via jexec over SSH, without needing direct SSH into the jail.

v1.1.0: ground-up refactor. Now subclasses the built-in ssh plugin and merges its options at import time, so ControlPersist, jump hosts, private keys, password_mechanism. About a quarter of the old code.

v1.2.0: adds ansible_jail_root to override the jls probe for nested / VNET jail setups.

System Administration: Week 11: Configuration Management, Part II

In this video, we continue our discussion of configuration management systems. We talk about state assertion, what states of a host we might care about, the CAP theorem and other fallacies of distributed systems, idempotence, eventual consistency and convergence, and the overlap of CM systems with other infrastructure components, yielding, eventually, infrastructure as a service.

Join us May 18-19 in Minneapolis, Minnesota ▶️ https://cd.foundation/blog/2026/04/10/cdcon-2026-tracks/

System Administration: Week 11: Configuration Management, Part I

In this video, we're starting our discussion of Configuration Management. We illustrate the general evolution of the management of system configuration and talk about defining services by abstracting individual requirements for system-specific and service-specific aspects. We present a few snippets of Puppet, Chef, and CFEngine code to give you a taste of some common CM systems.

I believe #kindness is key to our survival.

AWS now offers "S3 Files" to access S3 buckets as a file system. If you benchmark this vs regular file system access and S3 API access, let me know.

Years ago I needed to migrate millions of images from FS storage to S3 and tried to skip app changes by mounting the S3 bucket as a Linux FS. It worked, but performance sucked because the FS API requires a bunch of extra API calls that direct S3 doesn't.

So I'm curious if S3 Files solves that.

hey so this is probably completely pointless but: looking for a job (NZ or fully remote willing to hire a kiwi) in SRE, security, or linux/Unix system administration. 15 years expereince administering Linux and Unix boxes, intermediate level of experience working with docker compose and containerisation and container security. No prior job experience unfortunately, all those 15 years were mostly personal projects and small-scale stuff for friends. Currently running an entire multi-machine personal cloud infrastructure with a demonstration of all the services I have running at https://status.highenergymagic.net. Entirely willing to accept entry-level job placements, no expectation of being paid a lot or anything, just want to be doing something and move the needle a little on my current "being broke" status. #fedihired #infosec #cybersecurity #linux #unix #docker #sre #DevOps
