Five Cybersecurity Steps Every Small Business Should Take Right Now

‍

Running a small business means managing many priorities at once. Between serving customers, supporting employees, processing payments, working with vendors, and planning for growth, cybersecurity may feel like another complex responsibility competing for attention.

But protecting your business does not always require an expensive system or a large technology department. Several foundational practices can help reduce risk, strengthen day-to-day operations, and prepare your team to respond when something does not look right.

Cybersecurity is a Business Need

Cybersecurity is also more than a technology issue. It is a business issue that can affect operations, financial information, customer trust, and the ability to serve clients. The Cybersecurity and Infrastructure Security Agency advises small-business leaders to approach cyber risk as a business risk and to build a culture in which employees understand their role in protecting the organization.

The following five steps can help your business build a stronger security foundation.

1. Protect Important Accounts With Strong Authentication

Passwords remain an important first line of defense, but relying on a password alone may not provide enough protection for sensitive business accounts.

Require employees to use long, unique passwords for business systems and avoid reusing the same password across multiple accounts. A password manager can help create and securely store complex passwords without requiring employees to remember each one.

Whenever available, enable multifactor authentication, commonly called MFA. MFA requires an additional step beyond entering a password, such as approving a notification, using an authenticator application, or entering a temporary code.

This additional protection is especially important for:

• Business email accounts
• Online and mobile banking
• Payment and accounting systems
• Payroll applications
• Cloud storage
• Administrative accounts
• Vendor-management platforms

NIST recommends enabling MFA, particularly phishing-resistant MFA, on accounts that offer it. NIST also recommends strong passwords and consideration of a password manager.

Authentication codes should be treated like passwords. Employees should never share a password, one-time passcode, secure access code, or password-reset code in response to an unexpected email, text, or telephone call.

2. Keep Systems, Applications, and Devices Updated

Software updates do more than add features. Updates may also address security weaknesses that could otherwise be used to access a device, disrupt operations, or compromise information.

Create a consistent process for updating:

• Computers and mobile devices
• Operating systems
• Internet browsers
• Business applications
• Payment software
• Antivirus and security tools
• Routers and other connected equipment

When appropriate for your operations, automatic updates can help prevent important security fixes from being overlooked.

Businesses should also identify which devices and applications are essential to daily operations. Knowing what your business relies on can make it easier to assign responsibility for updates and recognize systems that may no longer be supported.

The Federal Trade Commission recommends setting a schedule for updating programs, applications, browsers, and operating systems. The FTC also recommends turning on automatic updates and maintaining regular backups of important files.

3. Train Employees to Recognize Suspicious Requests

Technology provides important protection, but employees are often the first people to encounter a suspicious email, fraudulent payment request, or impersonation attempt.

Provide employees with straightforward guidance on how to recognize:

• Unexpected requests for passwords or authentication codes
• Messages involving urgency or secrecy
• Changes to vendor payment instructions
• Unusual invoice or wire-transfer requests
• Links or attachments from unfamiliar senders
• Calls from someone claiming to represent a bank or trusted organization
• Requests that do not follow normal approval procedures

Training should also explain what employees should do when something appears suspicious. That may include pausing the interaction, avoiding links or attachments, independently verifying the request, and reporting the communication through an established internal channel.

CISA recommends developing a culture of awareness, educating employees about phishing and business email compromise, and providing basic cybersecurity training.

CNB’s previous cybersecurity content planning also identified employee training, software updates, strong passwords, MFA, and awareness of business email compromise as practical protections for small and medium-sized businesses.

Training should not be limited to a single annual activity. Short reminders, real-world examples, and periodic conversations can help keep security top of mind as fraud tactics evolve.

4. Establish Controls for Payments and Account Changes

A convincing message should never replace an established approval process.

Fraudsters may impersonate an owner, executive, employee, vendor, or financial institution to request a payment or obtain sensitive information. Business email compromise is one example of an attack that uses impersonation and manipulation to make employees believe they are communicating with a trusted colleague or leader.

Consider establishing procedures that require employees to:

• Independently verify new payment instructions
• Confirm vendor account changes using known contact information
• Review payment details before releasing funds
• Use separate initiation and approval roles for certain transactions
• Regularly review who has access to financial systems
• Establish transaction and user limits appropriate for each role
• Monitor account activity and transaction notifications
• Reconcile business accounts consistently

CNB fraud-prevention materials recommend independent verification of account changes, dual approval, appropriate user and company limits, review of transaction details, account reconciliation, and prompt attention to transaction notifications.

The right controls may vary depending on the size and complexity of the business. The important principle is consistency. Employees should know how payment requests are approved and should feel comfortable stopping a transaction that does not follow the normal process.

5. Prepare a Response Plan Before an Incident Occurs

Even strong preventive measures cannot eliminate every risk. Your business should know how it will respond if an employee clicks a suspicious link, an account is compromised, a device is lost, or business information becomes unavailable.

A basic incident response plan should identify:

• Who employees should contact
• Who can make decisions during an incident
• How affected accounts or systems will be secured
• Which vendors or financial institutions may need to be notified
• How business operations will continue
• Where important contact information is stored
• How critical data and files can be restored

Businesses should also back up important information and confirm that the information can be recovered when needed. A backup is most useful when it is protected, current, and tested.

CISA recommends that leadership review and approve a written incident response plan before an incident occurs. Its small-business guidance also emphasizes that cybersecurity culture cannot be delegated solely to the IT team.

Make Cybersecurity Part of Everyday Business

Cybersecurity does not need to begin with a complex transformation. It can begin with strong authentication, current software, informed employees, reliable payment controls, and a clear response plan.

Business owners set the tone. When leaders follow security procedures, encourage employees to verify unusual requests, and make it easy to report concerns, cybersecurity becomes part of everyday operations instead of an occasional project.

Start with the areas that could have the greatest effect on your business. Identify an owner for each action, document the process, and review your practices as the business grows.
