Cybersecurity
The practice of protecting digital systems, information, and services from misuse, disruption, or unauthorized access.
In simple terms
Cybersecurity is the set of habits and safeguards that help keep computers and information working for the people who should use them.
Technical explanation
It combines people, processes, and technical controls to manage risks to confidentiality, integrity, and availability across systems and data.
A practical program starts by identifying valuable systems and likely failure modes, then assigns owners for protection, detection, response, and recovery. Controls need periodic checks because technology and threats change.
Examples in practice
A small company backs up files, requires multifactor authentication, and limits who can change its payment settings.
For instance, the company also tests a restore, reviews administrator access every quarter, and gives staff a way to report suspicious messages. Those checks reveal whether the written policy works during an actual disruption.
Why it matters
A single technical tool cannot cover every way an organization can lose access to or control of its information.
