Introducing The Security Leader’s Operating System

There is one sentence I hear from information security leaders more than almost any other:

“I don’t have time to do what I need to do.”

The problem usually isn’t motivation, discipline, or effort. Security leaders already work hard. The deeper problem is that their ability to handle difficult work attracts more difficult work.

Questions, approvals, exceptions, vendor reviews, audit requests, incidents, meetings, unfinished decisions, and executive concerns all flow toward the person who has demonstrated that they can carry them. Eventually, being able to handle almost anything becomes the reason the leader has time to think about almost nothing.

I wrote The Security Leader’s Operating System to help change that.

Thinking

Security Leaders Don’t Need Another Productivity Trick

Most productivity systems concentrate on organizing work after it has already been accepted.

This field guide starts earlier.

Before deciding where a task belongs, it asks whether that work should exist in its current form at all. It applies the EDSAM mental model:

  • Eliminate work that does not need to happen.
  • Delegate outcomes that do not require the leader’s authority or judgment.
  • Simplify work until it produces the smallest useful result.
  • Automate the predictable parts of the work that remains.
  • Maintain only what must remain under the leader’s direct care.

The objective is not to help security leaders process an endlessly growing queue more quickly. It is to redesign the system so that less work requires the leader in the first place.

Protect the Work Only the Leader Can Do

Some work genuinely belongs with the security leader.

Setting risk appetite, challenging assumptions, translating technical exposure into business decisions, communicating during consequential events, developing people, and accepting residual risk cannot simply be optimized away.

But that work is often crowded out by management exhaust: status collection, repetitive reporting, preventable escalations, meeting preparation, evidence retrieval, routing questions, and processes that exist largely because they have always existed.

The guide introduces practical ways to distinguish leader-only work from work that can be removed, transferred, redesigned, or supported by better systems.

It includes:

  • A Money, Attention, and Time workload scan
  • The Eisenhower Matrix mapped into EDSAM
  • TaskGrid as an example of integrating urgency, importance, agency, commitments, planning horizons, and EDSAM dispositions
  • Information security workload playbooks
  • A recurring operating cadence
  • A 30-day reset
  • Capacity and decision tools
  • Field-ready worksheets and checklists
  • A NIST Cybersecurity Framework 2.0 scope check

AI Can Reduce Work—or Industrialize the Wrong Work

Modern LLMs, GPTs, skills, assistants, and agents make this conversation more urgent.

These tools can retrieve information, summarize evidence, compare documents, prepare decision packets, draft communications, and move bounded work through repeatable processes.

They can also accelerate bad processes, obscure missing context, accumulate excessive authority, and create new infrastructure that someone must maintain.

That is why the guide applies EDSAM before automation.

It explores how to divide work among humans, models, and deterministic systems; how to establish capability levels and autonomy budgets; and how to preserve accountable human judgment when AI-enabled workflows can create real consequences.

The important question is not simply, “Can AI perform this task?”

The better sequence is:

  1. Should this work exist?
  2. Who should own its outcome?
  3. What is the smallest useful result?
  4. Which parts are predictable enough to automate?
  5. What judgment, authority, or relationship must remain human?

A Field Guide, Not a Theory Book

This is intended to be used with the work already in front of you.

Choose one recurring meeting. One report. One approval queue. One source of preventable escalation. One hour of work that only you can perform.

Then apply the system.

A saved hour is useful. A redesigned workflow that prevents the same demand from returning every week is leverage. A clearer decision boundary makes the entire team stronger.

My broader goal is to leave behind a legacy of useful knowledge—methods that other people can test, challenge, improve, and carry forward. I hope this guide becomes part of that working library.

As you work through it, I would be interested to hear what you eliminate, delegate, simplify, automate, or deliberately maintain first.

AI Agents Are Already Working for You. Who’s Managing Them?

AI Agents Are Not Applications. They Are Digital Workers.

Most organizations are adopting AI agents faster than they are learning how to govern them.

That is the problem.

A chatbot that answers questions is one thing. An AI agent that can access business data, use tools, trigger workflows, generate artifacts, make recommendations, or alter enterprise state is something else entirely.

At that point, the organization is no longer just deploying software.

It is introducing a new kind of operational actor.

That actor needs identity.

It needs boundaries.

It needs oversight.

It needs evidence.

It needs a human owner.

It needs a kill switch.

In other words, AI agents must be managed more like digital workers than ordinary applications.

Third-Party Authentication Inventory Worksheet

We often get asked for worksheet questionnaires to help organizations inventory their third-party applications and the underlying authentication mechanisms. 

As such, we have developed a template for our clients and others to use for this purpose. 

You can easily distribute this worksheet to each part of the business or group, empowering them to complete it for each of their third-party applications. 

Once they return the data, you can extract it into any aggregation tool or vendor monitoring system you use. If you don’t have those tools available, you can process and monitor them manually using this easy spreadsheet for each line of business.

Why Emulate a PLC with a Raspberry Pi

One of the most powerful uses of emulating a PLC (Programmable Logic Controller) field device with a Raspberry Pi is that it provides an affordable and easily obtained platform for prototyping, performing ladder logic testing, and researching various industrial control systems and cybersecurity concepts.

Raspberry Pis are Affordable

Raspberry Pi models 3 and 4 are significantly more affordable than real PLCs. A typical PLC can cost hundreds or thousands of dollars.

The Raspberry Pi costs around $35-50 depending on your model choice. This makes them very accessible to hobbyists, students, researchers, developers, and anyone else who wants to work with the basics of industrial control systems. The low cost makes them ideal candidates to emulate a PLC in many scenarios.

Raspberry Pis are Easily Obtainable

PLCs can be quite difficult to come by, especially if you want one without any pre-existing software installed. Many manufacturers will not sell their products to third parties unless they have some kind of existing relationship. If you don’t already know someone at the manufacturer then you may need to pay a hefty upcharge. Additionally, purchasing the addons for power supplies, specific programming software, and such can quickly turn into a slog of paperwork and supporting tasks. The lead time and delivery times can take weeks to months.

The Raspberry Pi, on the other hand, can be purchased at many big-box electronics or computer stores, directly from many providers, or even delivered to your door from Amazon and other online sources. It uses a common USB power supply and can be configured and programmed using open source tools available online. Lead time is a couple of days to a few hours, letting you stay focused on your work.

The OpenPLC Project

The OpenPLC Project is a stable, well-documented toolkit for emulating basic PLC operations on the Pi. It has been used successfully to simulate a variety of different types of PLCs and includes support for ladder logic and other common PLC functions. You can find the programming reference and review the available capabilities here.

You can get OpenPLC up and running on a Pi in less than 30 minutes. In our testing, we were able to begin using the emulated PLC in our lab within an hour!

Going The Extra Mile With SCADABR

SCADABR is an open-source supervisory control and data acquisition software package designed to allow you to create interactive screens or human-machine interfaces (HMI) for your automation projects. It provides tools for creating graphical user interface widgets, event handlers, timers, and dialogs. With its ability to communicate with multiple controllers (including OpenPLC), ScadaBR is an ideal companion for the OpenPLC Runtime and Editor.

Using a Pi, OpenPLC, and SCADABR together, can get you a very powerful and useful PLC platform up and running for under $100 and in less than a few hours. Once implemented, you can use the platform to learn about industrial controls systems, ladder logic, PLC programming, and operations. You can also do basic ladder logic research and testing, and even prototyping for future real-world PLC deployments. Cybersecurity folks also have a very capable platform for learning about industrial control security requirements, performing vulnerability research, reverse engineering, or practicing their assessment skills in a safe environment.

While you might not get the full power of a true PLC (there are some limitations to Pi’s capabilities), you will likely get more than you expect. If you have an interest in or a need for some basic industrial control systems capabilities, this is a great place to start.

 

 

Automating SSL Certificate Management with Certbot and Let’s Encrypt

As we posted previously, following best practices for SSL certificate management is critical to properly secure your site. In that post, we discussed automating certificate management as a best practice. This post is an example of how to do just that.
 
To do so, we will use the highly-trusted free certificate provider Let’s Encrypt. We will also leverage the free certificate automation tool Certbot.
 

Installing Certbot

Installing Certbot is pretty easy, overall, but you do need to be comfortable with the command line and generally know how to configure your chosen web server. That said, if you check out the Certbot site, you will find a dropdown menu that will let you pick your chosen web server and operating system. Once you make your selections, simply follow the on-screen step-by-step instructions. In our testing, we found them to be complete and intuitive.
 

That’s It!

Following the on-screen instructions will have:

  • Certbot installed
  • Configure your web server for the certificate
  • Generate, get and install the certificate
  • Implement automatic renewals of the certificate to prevent expiration

You can literally go from a basic website to fully implemented and automated SSL in a matter of moments. Plenty of support is available from EFF for Certbot, or via Let’s Encrypt. In our testing, we ran into no issues and the implementation completed successfully each time.

Give it a shot! This might be one of the easiest and most effective security controls to automate. Together, Certbot and Let’s Encrypt can create a no-cost cryptography solution for your web sites in a very short amount of time.

Microsoft Making 2FA Easier with New App

Make sure you check this out if you use any of the Microsoft 2 factor authentication tools – they just released a new app for mobile devices to make their previously very painful mishmash of authentication tools easier!

I know a lot of clients and readers use the existing Microsoft authentication tools, so I will be eager to play with this and see just how much easier they have made it. Do you think it stands up to their claims of simplification? Let me know on Twitter (@lbhuston) what you come up with when you try it… 

80/20 Rule of Information Security

After my earlier this post about the SDIM project, several people on Twitter also asked me to do the same for the 80/20 Rule of Information Security project we completed several years ago. 

It is a list of key security projects, their regulatory mappings, maturity models and such. Great for building a program or checking yours against an easy to use baseline.

Thanks for reading, and here is where you can learn more about the 80/20 project. Click here.
