What Access Should You Give an AI Agent? Simple Rules for Controlling Risk
AI no longer just answers questions. Agents read email, move files, connect to company systems and push work forward on their own. For a business manager, the main question is no longer which model is best. It is what access the agent should get, and what you stand to lose if it gets something wrong.
The main danger is not necessarily "hacking" in the old sense. BleepingComputer reports that a malicious email, website or plugin can manipulate an agent into executing an attacker's commands, stealing data or deleting files. The agent does this using the same legitimate permissions we gave it. It is like a new employee who treats any note left on the desk as an order from the boss.
Assuming that "someone is surely watching the agent" is not reassuring either. The Register covered a red-team report finding that monitoring of OpenAI's agents during an attack on Hugging Face was only partial and easy to bypass. In another report, The Register described an attack tool designed to carry out 100,000 steps without human approval. The lesson from both is clear: without a stopping point and real oversight, an agent repeats its mistakes at machine speed.
The first rule is least privilege. An agent that drafts replies to customers does not need the CEO's mailbox or the finance folder. Create a separate account for each agent, start with read-only access, and open only the folders and systems it truly needs. Shared accounts and a single admin password are common in many Iranian companies, and if an agent connects through one of those, a simple deception puts everything at risk.
The second rule is human approval for sensitive actions. Write down the actions an agent may never take without a person's sign-off: payments and changes to bank details on an invoice, sending files outside the organization, deleting data, changing permissions and signing contracts. The approval should attach to the action itself, not just to the start of the task. A few minutes of delay costs little compared with a wrong transfer or a wiped folder.
The third rule is logging. You should be able to say afterward what the agent read, which tools it called and what it changed. Without that record, you cannot tell in an incident whether the cause was a malicious instruction, a model error or your own misconfiguration. Keep logs separate from the agent so it cannot alter them, and have a person review a sample regularly.
The fourth rule is testing in an isolated environment before real use. Try the agent first with sample data and test accounts, and deliberately put an email or page with a suspicious instruction in front of it to see how it reacts. Install plugins and skills only from trusted sources. Gen Digital has entered this space with a product called Agent Trust Hub, which verifies skills and controls agent behavior at runtime, but the core of the work is your own internal policy, not a product. In Iran, where unofficial and unvetted extensions are widely used, this simple caution pays off most. Before connecting any agent to customer data, also decide which foreign services that data would end up in.
If you want a place to start, pick one small, low-risk task, such as summarizing support emails with read-only access. Apply all four rules from day one, and widen access only when logs and tests give you confidence. Every new permission should be a deliberate decision, not a tool's default. Your IT team or MSP partner can help you define these boundaries and put them in place.
