* A brief description about TOMOYO: |
| 16 |
* |
| 17 |
* TOMOYO stands for "Task Oriented Management Obviates Your Onus". |
| 18 |
* TOMOYO is intended to provide the Domain-Based MAC utilizing task_struct. |
| 19 |
* |
| 20 |
* The biggest feature of TOMOYO is that TOMOYO has "accept mode". |
| 21 |
* The accept mode can automatically generate policy definition, |
| 22 |
* and dramatically reduces the policy definition labors. |
| 23 |
* |
| 24 |
* TOMOYO is applicable to figuring out the system's behavior, for |
| 25 |
* TOMOYO uses the canonicalized absolute pathnames and TreeView style domain transitions. |
