File System Integrity
A File System Integrity Check is implemented on SC boards and provides an
additional security mechanism that helps to mitigate security risks such as hacker
intrusion and malicious software installation. Since all Mediant 8000 software and
configuration is stored on the SC boards and then distributed to the corresponding
Mediant 8000 components (including Media Gateway and ES boards), implemented
integrity measures essentially apply to the Mediant 8000 as a whole.
When the Media Gateway software is installed, a snapshot of the file system is
created. This snapshot covers both the Media Gateway software and OS components,
and includes both binary and configuration files.
Media Gateway software periodically scans file system and compares it against the
snapshot. When unauthorized modifications are detected, a notification alarm is sent
to the EMS and the integrity status of the SC board's file system is updated
accordingly.
Each SC board performs the File System Integrity Check independently and reports
the results accordingly.
