Asset security refers to the protection of physical, digital, and information assets from theft, damage, unauthorised access, or misuse. In a cybersecurity and governance context, asset security includes classification, access controls, encryption, monitoring, and lifecycle management. Effective asset security ensures that sensitive data, intellectual property, and critical systems remain protected against internal and external threats. Organisations implement asset security policies aligned with frameworks such as ISO 27001 and NIST to maintain compliance and reduce risk exposure. By integrating asset security into enterprise risk management processes, businesses achieve improved visibility, accountability, and resilience.
