Archiva enhances data security by implementing strong access control mechanisms, ensuring that only authorized users can upload or download artifacts. It supports user authentication, role-based permissions, and integration with organizational security systems. By restricting access to approved repositories and validating metadata, Archiva prevents unauthorized or corrupted artifacts from entering the system. Audit logs help track all repository activities, ensuring accountability and transparency. Additionally, its proxying capabilities allow control over external repository sources, protecting internal systems from untrusted components. Together, these measures make Archiva a secure and dependable platform for managing critical build artifacts.
