Cyber security tips for small businesses

By SBI Editorial Team

Cyber security is not just a technical issue — it’s a business risk.

If your business data is lost, stolen, or compromised, recovery can be costly, time-consuming, and damaging to your reputation.

1. Use strong and secure passphrases

Instead of passwords, use passphrases — four or more random words that are easy to remember but hard to guess.

Best practices:

change passphrases regularly
don’t share them with others
check if your passphrases have been compromised and change them immediately if they have

2. Use multi-factor authentication (MFA)

Multi-factor authentication adds an extra layer of protection. Even if someone gets your passphrase, MFA requires another verification step — like a code sent to your phone or email.

Enable MFA on all business-critical accounts.

3. Manage employee access

Implement access controls to limit what your staff can access. This includes restricting access to sensitive systems, programs, and files.

Benefits:

reduces the impact of a cyber incident
limits exposure to sensitive data
helps prevent internal data breaches

4. Remove access for past employees

One of the most common cyber security oversights is former employees who still have access to business systems.

When an employee leaves or changes roles:

remove their access immediately
update shared account login details
review what systems they had access to

5. Back up your data regularly

Regular backups are essential. Use either:

a physical backup (external hard drive)
a cloud-based backup solution

This protects you if data is lost, stolen, or affected by ransomware.

6. Avoid unknown USBs or external drives

USBs and external hard drives can contain malware. Only use devices from trusted sources.

7. Only download software from trusted sources

Avoid downloading unknown programs or opening suspicious email attachments. Malicious files can install ransomware or steal sensitive business information.

8. Secure your wireless network

Avoid using public Wi-Fi for business transactions — not all networks are secure.

Tips:

use a strong Wi-Fi password
consider separate networks for staff and customers
set your Wi-Fi network as private (not public)

Simple security habits go a long way. Most cyber incidents affecting small businesses are preventable with basic precautions.
