Cybersecurity Basics for Small Businesses

A small business does not need an enterprise security department to reduce common cyber risks. It does need to protect the accounts, devices and information that keep the business operating.

Know what would hurt to lose

Identify essential systems and information: email, accounting, customer records, payment systems, websites, cloud storage and operational files. Consider what would happen if each became unavailable, altered or public.

Use multi-factor authentication

Enable strong multi-factor authentication wherever practical, especially for email, banking, cloud administration, website administration and other important accounts.

A stolen password should not automatically provide full access to the business.

Patch software and devices

Security updates fix known vulnerabilities. Enable automatic updates where appropriate and replace unsupported software or devices when the risk can no longer be managed sensibly.

Back up essential information

Backups can help recover from ransomware, equipment failure, theft and human error. Determine what must be backed up and how often it changes.

Most importantly, verify that important information can actually be restored. An untested backup is only a hope.

Limit access

Employees and contractors should have access to the systems needed for their work, not every account the business owns. Remove access promptly when it is no longer required.

Train people to recognize common attacks

Phishing emails, fake invoices, malicious links and impersonation attempts frequently target human behaviour. Staff should know how to stop and verify an unusual payment or password request.

Protect email carefully

Email often controls password resets for other services, making a compromised mailbox especially dangerous. Secure administrator and financial accounts particularly carefully.

Have an incident plan

Decide in advance who will respond if an account is compromised, ransomware appears or customer information is exposed. Keep essential contact information somewhere accessible even if normal computer systems are unavailable.

Secure cloud services too

Using a reputable cloud provider does not eliminate the business’s responsibilities. Configure accounts securely, control administrator access and understand what information is being stored.

Cybersecurity is business continuity

The goal is not perfect security. It is reducing preventable incidents and ensuring the business can respond and recover when something goes wrong.

Protect money movement with a second check

Payment fraud often relies on urgency and impersonation. A message that appears to come from an owner, supplier or employee may request a changed bank account or urgent transfer. Establish an independent verification step for unusual payments or changes to banking instructions.

Separate administrator accounts from ordinary work

Administrator privileges should be limited to tasks that actually require them. Using highly privileged accounts for everyday browsing and email increases the consequences if that account or device is compromised.

Know your important providers

Keep a secure inventory of critical services such as domain registration, email, accounting, payment processing, cloud storage and website hosting. Record who has authorized access and how recovery works. This can dramatically reduce confusion during an incident.

Practice recovery before an emergency

Choose an important file or system and test whether it can really be restored from backup. Confirm that recovery contacts are current and that multi-factor authentication does not depend entirely on one lost phone.

Report and learn from incidents

When something suspicious occurs, preserve relevant information and seek qualified assistance where needed. Depending on the incident, notification or reporting obligations may apply. After recovery, determine what control could reduce the chance or impact of the same problem happening again.
