|
|
+ TOMOYO stands for "Task Oriented Management Obviates Your Onus". |
|
|
+ TOMOYO is intended to provide the Domain-Based MAC |
|
|
+ utilizing task_struct. |
|
|
+ |
|
|
+ The word "domain" in TOMOYO is a class that a process |
|
|
+ (i.e. task_struct) belong to. |
|
|
+ The domain of a process changes whenever the process |
|
|
+ executes a program. |
|
|
+ This allows you to classify at the finest level. |
|
|
+ The access permission is granted to domains, not to processes. |
|
|
+ Policy is defined as "Which domain can access to which resource.". |
|
|
+ |
|
|
+ The biggest feature of TOMOYO is that TOMOYO has "learning mode". |
|
|
+ The learning mode can automatically generate policy definition, |
|
|
+ and dramatically reduces the policy definition labors. |
|
|
+ |
|
|
+ TOMOYO is applicable to figuring out the system's behavior, for |
|
|
+ TOMOYO uses the canonicalized absolute pathnames and |
|
|
+ TreeView style domain transitions. |
|
|
+ |
|
|
+ You can make custom root fs with minimum files |
|
|
+ to run minimum applications with TOMOYO. |
|
|
+ |
|
|
+CONFIG_TOMOYO_MAX_ACCEPT_ENTRY |
|
|
+ This is the default value for maximal ACL entries |
|
|
+ that are automatically appended into policy at "learning mode". |
|
|
+ Some programs access thousands of objects, so running |
|
|
+ such programs in "learning mode" dulls the system response |
|
|
+ and consumes much memory. |
|
|
+ This is the safeguard for such programs. |
|
|
+ |
|
|
+CONFIG_TOMOYO_MAX_GRANT_LOG |
|
|
+ This is the default value for maximal entries for |
|
|
+ access grant logs that the kernel can hold on memory. |
|
|
+ You can read the log via /proc/ccs/grant_log. |
|
|
+ If you don't need access grant logs, |
|
|
+ you may set this value to 0. |
|
|
+ |
|
|
+CONFIG_TOMOYO_MAX_REJECT_LOG |
|
|
+ This is the default value for maximal entries for |
|
|
+ access reject logs that the kernel can hold on memory. |
|
|
+ You can read the log via /proc/ccs/reject_log. |
|
|
+ If you don't need access reject logs, |
|
|
+ you may set this value to 0. |
|
|
+ |
|
|
+CONFIG_SYAORAN |
|
|
+ Say Y or M here to support the Tamper-Proof Device Filesystem. |
|
|
+ |
|
|
+ SYAORAN stands for |
|
|
+ "Simple Yet All-important Object Realizing Abiding Nexus". |
|
|
+ SYAORAN is a filesystem for /dev with Mandatory Access Control. |
|
|
+ |
|
|
+ SAKURA can make root fs read-only, but the system can't work |
|
|
+ if /dev is read-only. Therefore you need to mount a writable |
|
|
+ filesystem (such as tmpfs) for /dev if root fs is read-only. |
|
|
+ |
|
|
+ But the writable /dev means that files on /dev might be tampered. |
|
|
+ For example, if /dev/null is deleted and re-created as a symbolic |
|
|
+ link to /dev/hda by an attacker, the contents of the IDE HDD |
|
|
+ will be destroyed at a blow. |
|
|
+ |
|
|
+ Also, TOMOYO controls file access by pathnames, |
|
|
+ not by security labels. |
|
|
+ Therefore /dev/null, for example, might be tampered |
|
|
+ if a process have write permission to /dev/null . |
|
|
+ |
|
|
+ SYAORAN can ensure /dev/null is a character device file |
|
|
+ with major=1 minor=3. |
|
|
+ |
|
|
+ You can use SAKURA to make /dev not unmountable. |
