AI Security for Business: Before You Give AI Access to Your Systems
What business owners should know about permissions, access, and accountability
By Norm Herron, Partner, Atomic Technology Solutions
AI security for business is becoming more important as artificial intelligence moves beyond answering questions and drafting emails. New AI tools can summarize meetings, update customer records, search company files, prepare reports, and take actions across multiple business applications. That can save a tremendous amount of time. It also creates an important cybersecurity question:
What should an AI tool be allowed to access?
When an employee uses an AI assistant to help write a document, the risk may be relatively limited. When an AI agent can open files, connect to email, access customer information, or make changes inside a business system, the conversation becomes much more serious.
The issue is not whether your business should use AI. The issue is whether you are giving these tools the right level of access, oversight, and accountability.
AI Access Is Still Business Access
Every AI tool that connects to your systems needs some form of digital identity. It may operate through an employee’s account, a shared login, an application connection, or its own service account.
That identity determines what the tool can see and what it can do.
If an AI tool is connected using an account with broad administrative privileges, it may have access to far more information than it actually needs. A compromised account, incorrect instruction, poorly configured integration, or simple human mistake could expose files, customer records, financial data, or other sensitive information.
This is why the principle of least privilege still matters. Each person, application, and AI tool should receive only the access required to perform its assigned task.
Recent guidance from the National Institute of Standards and Technology emphasizes the importance of strong identity controls as businesses begin using more autonomous AI systems. AI may be new, but the need to control access is not. NIST
Start With the Data
Before connecting an AI tool to a business application, ask what information it will be able to reach.
For example:
- Does it need access to every company file or only one approved folder?
- Can it read customer records?
- Can it send messages or make changes without approval?
- Will information be stored by the AI provider?
- Can administrators review what the tool accessed and what actions it performed?
- What happens to the data if the account or subscription is canceled?
These questions should be answered before the connection is activated, not after something goes wrong.
This is especially important for businesses that handle medical information, financial records, legal documents, government contract information, or other regulated data.
Avoid Shared Accounts
An AI tool should not be connected through a shared employee login whenever an individual account or managed service account is available.
Shared accounts make it difficult to determine who approved an action, changed a setting, or accessed a file. They also create problems when an employee leaves the company or changes roles.
Separate identities make it easier to:
- Limit permissions
- Require multifactor authentication
- Monitor activity
- Remove access quickly
- Maintain a reliable audit trail
Multifactor authentication remains one of the most effective ways to protect accounts from unauthorized access, particularly when it is paired with strong identity and access management practices. CISA
Keep a Human in the Loop
Not every AI action should happen automatically.
Businesses should decide which activities an AI tool can complete independently and which require human review. Drafting an internal summary may carry relatively little risk. Sending a customer communication, changing financial information, deleting files, or modifying account permissions deserves a higher level of oversight.
A practical approach is to divide AI tasks into three categories:
- Low risk: The AI can complete the task automatically.
- Moderate risk: The AI can prepare the work, but a person must approve it.
- High risk: The task should remain under direct human control.
The more sensitive the data or consequential the action, the more important human approval becomes.
Know Which AI Tools Your Team Is Using
Employees often begin using AI tools because they are helpful and easy to access. That means a business may already have company information moving through AI platforms without management or IT realizing it.
Instead of issuing a vague ban that may be ignored, create a simple AI use policy that explains:
- Which tools are approved
- What information employees may enter
- What information is prohibited
- When IT approval is required
- Who is responsible for reviewing new tools
- How employees should report a mistake or suspected exposure
Employees are more likely to follow rules when the rules are practical, specific, and easy to understand.
AI Security Does Not Need to Be Complicated
You do not need to stop experimenting with AI. You do need to treat an AI connection with the same care you would give any employee, vendor, or application requesting access to company systems.
Before giving an AI tool access, identify what it needs, limit what it can reach, protect the account, monitor its activity, and maintain human approval for higher-risk actions.
AI can become a valuable part of your business. The goal is to make sure it works for your organization without quietly creating access you did not intend to give.
