Cybersecurity Basics Every Small Business Owner Should Know

Nearly half of all cyberattacks target small businesses, precisely because attackers know defenses are thin. The good news: most breaches exploit basic weaknesses, which means basic defenses stop most attacks. Here is where to start.

Enable Multi-Factor Authentication Everywhere

Passwords alone are not enough. Multi-factor authentication blocks the vast majority of account takeover attempts, even when passwords leak. Turn it on for email, banking, cloud storage, and every business account that offers it. This single step does more than any other.

Keep Software Updated

Most ransomware spreads through known vulnerabilities that already have patches. Enable automatic updates on operating systems, browsers, and business applications. An unpatched system is an open invitation.

Train Your Team on Phishing

Your employees are both your biggest vulnerability and your best defense. Phishing emails cause the majority of breaches. Run short, regular training sessions, and establish a simple rule: when in doubt about an email, verify through a separate channel before clicking or paying.

Back Up Everything, Then Test the Backup

Ransomware only works if losing your data is catastrophic. Maintain automated backups stored separately from your main systems, and periodically verify you can actually restore from them. A backup you have never tested is a hope, not a plan.

Limit Access by Role

Not everyone needs access to everything. Give employees the minimum permissions required for their jobs. When someone leaves, revoke access the same day. Most insider incidents, accidental or otherwise, start with excessive access.

Cybersecurity does not require a big budget, just consistent basics. Attackers look for easy targets. Make sure that is not you.
