In cybersecurity, adhesion refers to the concept of how strongly a digital entity, such as a file, code, or process, attaches or integrates itself to another system or software. This term is often used to describe how malware or unauthorized code can bind to legitimate applications or operating systems, making detection and removal more difficult. Understanding adhesion is important for developing effective defense mechanisms, as highly adhesive threats can persist through system updates or reboots. Techniques to counteract adhesion include regular system scans, application whitelisting, and monitoring for unusual activity within integrated components.
