Zero Trust for IT Governance and Risk Management: A Systematic Review and Conceptual Framework
This study employs a PRISMA 2020 systematic review of 73 peer-reviewed articles to bridge the gap between technical Zero Trust implementations and organizational governance, proposing a conceptual framework that links continuous verification and identity-centric controls to enhanced risk management and strategic IT objectives while highlighting critical gaps in SME adoption and AI-driven automation.

The Great Digital Fortress Breakup
Imagine the internet as a giant, bustling city. For decades, the way we kept this city safe was by building a massive, impenetrable wall around the downtown area. This was the "traditional security model." If you had a badge to get inside the city gates, you were trusted completely. You could walk anywhere, talk to anyone, and touch anything without anyone asking for your ID again. It was like having a VIP pass that never expired.
But then, the city changed. People started building secret tunnels, flying drones over the walls, and working from coffee shops outside the city limits. The "wall" stopped making sense because the city wasn't just one place anymore; it was everywhere. This is where Zero Trust comes in. Think of Zero Trust not as a wall, but as a super-strict bouncer at every single door, elevator, and hallway inside the building. In this new world, you don't get trusted just because you're inside the building. You have to prove who you are every single time you try to open a door, even if you're just walking to the next room. It's a philosophy that says, "Never trust, always verify."
This paper is a massive detective story about how this new "bouncer" system changes the way organizations manage risk and run their digital lives. The researchers wanted to know: Does this strict, constant checking actually make companies safer and better at following the rules? They didn't just guess; they gathered and analyzed 73 different studies to see what the evidence says.
The Great Digital Detective Hunt
The authors of this paper, a team of researchers from universities in Yemen, India, and beyond, decided to take a step back and look at the whole picture. Instead of building a new security system themselves, they acted like digital librarians and detectives. They scoured the world's biggest academic libraries (like Scopus and Google Scholar) for any serious research published between 2020 and early 2026. They were looking for stories about "Zero Trust" and how it affects how companies handle danger and make decisions.
After a rigorous filtering process—where they tossed out 1,933 studies that were either duplicates, not peer-reviewed, or just didn't fit the criteria—they were left with a final "hall of fame" of 73 studies. These 73 papers were the gold they used to build their understanding.
What They Found: The "Always Check" Revolution
The big takeaway from their investigation is that Zero Trust is indeed a game-changer, but it's not a magic wand. The paper suggests that moving to this "always verify" system helps organizations in three main ways:
- It Stops the Sneak Attack: In the old days, if a hacker got past the front door, they could wander around the whole building freely. With Zero Trust, the building is divided into tiny, locked rooms (a concept called "micro-segmentation"). If a hacker breaks into the kitchen, they can't just walk into the server room next door. The paper finds that this significantly limits how far a bad actor can move once they are inside.
- It Makes the Lights Brighter: The system forces organizations to keep a constant watch on everything. It's like having a security camera that doesn't just record, but also analyzes every movement. This helps companies spot trouble faster and understand exactly where their risks are.
- It Helps with the Rules: Because Zero Trust is so organized and keeps detailed logs of who did what and when, it makes it much easier for companies to prove they are following laws and regulations (like GDPR or ISO standards).
However, the authors are careful to point out that this isn't a "plug-and-play" solution. The paper explicitly argues against the idea that you can just buy a piece of software and call it a day. They found that the success of Zero Trust depends heavily on culture. If the people in the company don't want to change, or if the leaders don't support the constant checking, the system fails. It's like having a super-strict bouncer, but if the employees keep letting their friends in without ID, the whole system breaks.
The "Socio-Technical" Puzzle
One of the most interesting things the paper discovered is that Zero Trust is more than just technology; it's a mix of people, rules, and gadgets. The researchers call this a "socio-technical paradigm."
They found that while the technology (like AI and blockchain) is cool and helpful, it's the human side that often trips things up. For example, the paper notes that small businesses (SMEs) often struggle with this because they don't have the money or the experts to set up such a complex system. The evidence suggests that while big companies are getting good at this, smaller ones are still figuring it out.
The paper also highlights that the world is moving fast. New technologies like Artificial Intelligence (AI) are being used to help the "bouncers" work faster, predicting where attacks might come from before they happen. But the authors warn that AI itself brings new risks, and we need to be careful about how we use it.
The Verdict: A New Way of Thinking
So, what is the final conclusion? The paper proposes a new framework (a kind of blueprint) that shows how Zero Trust connects the dots between security controls and the big-picture goals of a company.
The authors suggest that Zero Trust is the future, but it's a journey, not a destination. It transforms security from a static wall into a dynamic, living system that adapts to threats in real-time. However, they are clear that this is suggested by the current evidence, not a guaranteed fact for every single situation. The effectiveness varies depending on how mature the organization is and how well they handle the cultural shift.
In short, the paper tells us that the old "trust everyone inside the wall" idea is dead. The new rule is "trust no one, check everyone, all the time." But to make it work, you need more than just code; you need a team that believes in the system and a culture that supports it. The research suggests that if organizations can get this right, they will be much better at stopping hackers, managing risks, and staying compliant with the rules of the digital world.
