Information Security, often referred to as InfoSec, refers to the processes and tools designed and deployed to protect sensitive business information from modification, disruption, destruction, and inspection.
Information Security and CyberSecurity are often confused. InfoSec is a crucial part of cybersecurity, but it refers exclusively to the processes designed for data security. Cybersecurity is a more general term that includes InfoSec.
An ISMS is a set of guidelines and processes created to help organizations in a data breach scenario. By having a formal set of guidelines, businesses can minimize risk and can ensure work continuity in case of a staff change. ISO 27001 is a well-known specification for a company ISMS.
