Data security
iSM has few features that require data to be stored on the file system of the operating system. iSM stores iSM-specific
configuration files in a location that is accessible only to administrators or root users. iSM configuration includes feature states
and other intermediate files necessary for providing uninterrupted services.
Data storage security settings
iSM stores all the artifacts such as iSM binaries and configuration files on the operating system file system that is restricted to
administrator accounts only.
Data at rest encryption
iSM artifacts are stored unencrypted on the file system that is restricted to administrator access.
Data erasure
iSM uninstall erases all iSM-specific configuration data and intermediate files. Explicit SupportAssist collections saved in a
different path are not cleaned up. On Linux operating systems and Debian-based operating systems, uninstalling iSM retains
configuration files as per RedHat Package Manager (RPM) and Debian Package (dpkg) specifications respectively.
