Cyber security is how a business protects its people, devices, systems and data from digital threats.
It combines technology, processes and staff awareness to reduce the likelihood of an attack and limit the disruption it can cause.
Cyber resilience is your ability to prepare for, respond to and recover from a cyber incident.
It includes secure backups, incident response plans and business continuity measures that help your business keep operating when something goes wrong.
Common threats include phishing, stolen passwords, ransomware, malicious software, fraudulent emails and attacks that exploit outdated systems.
Many incidents begin with a simple mistake or overlooked weakness, making staff awareness just as important as technical protection.
Start with the fundamentals.
Use multi-factor authentication, keep software updated, restrict access to sensitive information, maintain secure backups, and train staff to recognise suspicious activity.
Regular security reviews can then identify gaps and help you prioritise further improvements.
Contact your IT or cyber security provider immediately and follow your incident response plan.
The priority is to contain the incident, understand what has been affected and restore systems safely.
Afterwards, review what happened and strengthen any weaknesses that were exposed.
