Cybersecurity is the practice of protecting systems and data from unauthorized access, misuse or theft. In the modern world, where we rely on computers for communication (email, texting), entertainment (interactive video games, social media, apps), travel (navigation systems) and so much more, cybersecurity is critical to keep your information safe from malicious attackers.

Cyberattackers are motivated by a variety of things, from simple curiosity to political activism to financial gain. The attackers may be individuals, or a state-sponsored attack team that has the resources to target a specific company or government agency.

Strong cybersecurity prevents attacks by ensuring that all devices and networks are protected using a variety of methods, from encryption to threat scanning. It also includes plans for how to respond to an attack, such as restoring systems and data quickly to minimise business disruption and the loss of valuable information.

The rise of remote work and the use of personal devices means that organisations must protect a diverse range of endpoints – desktops, laptops, smartphones, tablets, IoT devices and more. This requires a security architecture that is complex and requires specialised knowledge and skills to manage.

Effective cyber security also enables organisations to comply with regulatory requirements and ensures that data is secure in the event of an unforeseen breach or incident. It involves regularly training employees, applying protective measures to sensitive information and identifying priority roles that reduce risk the most. It also involves systems for organising and securing data effectively, such as by separating sensitive information into different databases and using encrypted communications.
