Cybersecurity Checklist for Small Businesses

A cybersecurity checklist gives small businesses a practical way to review important security items on a regular schedule.

Why this matters

Without a checklist, security reviews are often skipped or handled only after something breaks. That can leave old accounts, weak settings, exposed files, or backup gaps unnoticed.

A simple checklist helps the business build a repeatable process that employees and managers can understand.

Common signs of the problem

Small businesses usually notice the issue through daily confusion, delays, repeated support requests, or security gaps.

• No one knows the last time security settings were reviewed.
• Account access is handled differently every time.
• Shared folders and external links are not checked.
• Backups are assumed to work but are not verified.
• Security tasks depend on memory instead of documentation.

What to review first

Start with the items below. The goal is to create a clear, practical process that can be repeated.

1. List all core business systems.
2. Review users and administrator accounts.
3. Review password and MFA settings.
4. Review shared files and external access.
5. Review employee devices.
6. Review backup status.
7. Document what was reviewed and what needs follow-up.
