Compromise of another partition in Time and Space Partitioning OS or other types of satellite hypervisors

If a partitition is compromised, access to a critical partition can be gained through ports allowed by hypervisor. Information security is usually configured at the application level, with the execution confined to the application's partition and controlled communication with the remaining partitions. Time and Space Partitioning or other satellite hypervisor types should protect system from interferences. All communication passes through the security components, which can include monitoring and cryptographic mechanisms.
