11.10. Configuring Constraints
11.10.1. Configure Sensitivity Constraints
リンクのコピーリンクがクリップボードにコピーされました!
Each Sensitivity Constraint defines a set of resources that are considered "sensitive". A sensitive resource is generally one that either should be secret, like passwords, or one that will have serious impact on the server, like networking, JVM configuration, or system properties. The access control system itself is also considered sensitive. Resource sensitivity limits which roles are able to read, write or address a specific resource.
Sensitivity constraint configuration is in the Management API at
/core-service=management/access=authorization/constraint=sensitivity-classification.
Within the management model each Sensitivity Constraint is identified as a
classification. The classifications are then grouped into types. There are 39 included classifications that are arranged into 13 types.
To configure a a sensitivity constraint, use the
write-attribute operation to set the configured-requires-read, configured-requires-write, or configured-requires-addressable attribute. To make that type of operation sensitive set the value of the attribute to true, otherwise to make it nonsensitive set it to false. By default these attributes are not set and the values of default-requires-read, default-requires-write, and default-requires-addressable are used. Once the configured attribute is set it is that value that is used instead of the default. The default values cannot be changed.
Example 11.5. Make reading system properties a sensitive operation
[domain@localhost:9999 /] cd /core-service=management/access=authorization/constraint=sensitivity-classification/type=core/classification=system-property
[domain@localhost:9999 classification=system-property] :write-attribute(name=configured-requires-read, value=true)
{
"outcome" => "success",
"result" => undefined,
"server-groups" => {"main-server-group" => {"host" => {"master" => {
"server-one" => {"response" => {"outcome" => "success"}},
"server-two" => {"response" => {"outcome" => "success"}}
}}}}
}
[domain@localhost:9999 classification=system-property] :read-resource
{
"outcome" => "success",
"result" => {
"configured-requires-addressable" => undefined,
"configured-requires-read" => true,
"configured-requires-write" => undefined,
"default-requires-addressable" => false,
"default-requires-read" => false,
"default-requires-write" => true,
"applies-to" => {
"/host=master/system-property=*" => undefined,
"/host=master/core-service=platform-mbean/type=runtime" => undefined,
"/server-group=*/system-property=*" => undefined,
"/host=master/server-config=*/system-property=*" => undefined,
"/host=master" => undefined,
"/system-property=*" => undefined,
"/" => undefined
}
}
}
[domain@localhost:9999 classification=system-property]
What roles will be able to perform what operations depending on the configuration of these attributes is summarized in Table 11.2, “Sensitivity Constraint Configuration outcomes”.
| Value | requires-read | requires-write | requires-addressable |
|---|---|---|---|
true
|
Read is sensitive.
Only Auditor, Administrator, SuperUser can read.
|
Write is sensitive.
Only Administrator and SuperUser can write
|
Addressing is sensitive.
Only Auditor, Administrator, SuperUser can address.
|
false
|
Read is not sensitive.
Any management user can read.
|
Write is not sensitive.
Only Maintainer, Administrator and SuperUser can write. Deployers can also write the resource is an application resource.
|
Addressing is not sensitive.
Any management user can address.
