What is EN ISO 27005:2019?

EN ISO 27005:2019, also known as ISO/IEC 27005:2018, is a standard that provides guidelines for information security risk management. It offers a systematic and comprehensive approach to identifying, assessing, and managing risks to the confidentiality, integrity, and availability of an organization's information assets.

Understanding the Basics of EN ISO 27005:2019

The standard emphasizes the importance of risk assessment and the need for organizations to establish a formalized process to evaluate the potential impact of threats and vulnerabilities on their information systems. It helps organizations identify and prioritize risks, enabling them to implement appropriate controls to mitigate or manage those risks effectively.

Risk assessment is a vital component of EN ISO 27005:2019. It involves analyzing both internal and external factors that may pose a risk to the organization's information assets. By understanding these risks, organizations can make informed decisions and allocate resources to protect against and respond to potential incidents.
