Cybersecurity

Also written: InfoSec, Cyber security

Protecting computer systems and networks from digital attacks and unauthorized access.

In plain terms

Cybersecurity means keeping computers, networks, and digital information safe from bad actors. This includes preventing hackers from stealing data, disrupting services, or taking control of systems.

For example, a company might use cybersecurity measures like strong passwords, firewalls, and software updates to protect its customer data from being stolen.

The expert version

Cybersecurity encompasses the practices and technologies designed to protect digital assets from unauthorized access, damage, or disruption. It involves a multi-layered approach including network security, application security, data security, and incident response.

Key challenges include the evolving threat landscape, the complexity of modern systems, and balancing security with usability and performance.

Why it matters now

Frontier AI labs are integrating advanced cybersecurity features into their models. This is seen in new models like Google's Gemini 4 Argon, which developers can use for cybersecurity tools, and OpenAI's GPT-5.4, which includes specialized safety mitigations for cybersecurity.
