Cyber security fundamentals for Caribbean small businesses

Why Caribbean businesses are attractive targets

Attackers select for value and weakness together. The region concentrates both: offshore financial and corporate services handle high-value transactions; tourism and marine businesses process card payments and personal data year-round; and many organisations run with small or outsourced IT support, so controls that a larger firm takes for granted are absent.

Business email compromise is the dominant pattern. An attacker gains access to a mailbox, watches an invoice conversation for weeks, then intervenes at the payment moment with amended bank details. No malware is involved, which is why antivirus alone never catches it.

The five controls that matter most

These are the controls assessed by Cyber Essentials, and they map neatly onto the incidents we actually see in the region.

• Boundary firewalls and internet gateways — control what can reach your network and from where.
• Secure configuration — remove default accounts and passwords, disable unused services, lock down administrative interfaces.
• Access control — least privilege, no shared logins, separate administrator accounts, and multi-factor authentication on email, remote access and finance systems.
• Malware protection — reputable endpoint protection kept current on every device, including laptops taken off-island.
• Patch management — apply security updates to operating systems, browsers, plugins and firmware within days, not quarters.

Beyond the basics: people and recovery

Technical controls fail at the point where a person is persuaded. Short, regular awareness training focused on the specific scams your staff will meet — payment redirection, false urgency from a director, fake booking enquiries with attachments — outperforms an annual policy document nobody reads.

Assume something will get through eventually and plan for recovery. Backups must be automated, encrypted, held off-island and, critically, tested by restoring them. A backup nobody has restored is a hypothesis. Write a one-page incident plan naming who is called, who can authorise a shutdown and who speaks to clients, and rehearse it once a year.

Where to start if you have nothing in place

Sequence by risk reduction per unit of effort. Turn on multi-factor authentication for email today — it stops the majority of account takeovers on its own. Then inventory devices and accounts, because you cannot protect assets you have not listed, and remove ex-staff and dormant accounts. Then fix patching. Then arrange tested off-island backups.

That programme is achievable for a small firm in a matter of weeks and puts you ahead of most of your regional peers, which matters because attackers are opportunistic and move on to easier targets.
