Definition
Asset security is the practice of protecting an organization's valuable resources, including hardware, software, data, and intellectual property, from unauthorized access, use, disclosure, disruption, modification, or destruction. It involves identifying, classifying, and managing these assets throughout their lifecycle to ensure their confidentiality, integrity, and availability. Implementing asset security controls helps prevent data breaches, system failures, and financial losses, thereby maintaining business continuity and trust. For instance, a company might implement strict access controls and encryption for sensitive customer databases to protect personal information. This differs from data security, which focuses specifically on protecting data itself, whereas asset security encompasses the broader protection of the systems and resources that hold and process that data. Asset security is a core concept tested on certifications like CompTIA Security+, CySA+, and CISSP.
