# Vault Enterprise Control Groups
|
|
|
|
-> **Note**: This feature requires [Vault Enterprise](https://www.hashicorp.com/products/vault/)
|
|
with the Governance And Policy Module.
|
|
|
|
Vault Enterprise has support for Control Group Authorization. Control Groups
|
|
add additional authorization factors to be required before satisfying a request.
|
|
|
|
When a Control Group is required for a request, a limited duration response
|
|
wrapping token is returned to the user instead of the requested data. The
|
|
accessor of the response wrapping token can be passed to the authorizers
|
|
required by the control group policy. Once all authorizations are satisfied,
|
|
the wrapping token can be used to unwrap and process the original request.
|
|
|
|
## Control Group Factors
|
|
|
|
Control Groups can verify the following factors:
|
|
|
|
- `Identity Groups` - Require an authorizer to be in a specific set of identity
|
|
groups.
|
|
|
|
## Control Groups In ACL Policies
|
|
|
|
Control Group requirements on paths are specified as `control_group` along
|
|
with other ACL parameters.
|
|
|
|
### Sample ACL Policies
|
|
|
|
```
|
|
path "secret/foo" {
|
|
capabilities = ["read"]
|
|
control_group = {
|
|
factor "ops_manager" {
|
|
identity {
|
|
group_names = ["managers"]
|
|
approvals = 1
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
The above policy grants `read` access to `secret/foo` only after one member of
|
|
the "managers" group authorizes the request.
|
|
|
|
```
|
|
path "secret/foo" {
|
|
capabilities = ["create", "update"]
|
|
control_group = {
|
|
ttl = "4h"
|
|
factor "tech leads" {
|
|
identity {
|
|
group_names = ["managers", "leads"]
|
|
approvals = 2
|
|
}
|
|
}
|
|
factor "super users" {
|
|
identity {
|
|
group_names = ["superusers"]
|
|
approvals = 1
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
The above policy grants `create` and `update` access to `secret/foo` only after
|
|
two member of the "managers" or "leads" group and one member of the "superusers"
|
|
group authorizes the request. If an authorizer is a member of both the
|
|
"managers" and "superusers" group, one authorization for both factors will be
|
|
satisfied.
|
|
|
|
## Control Groups in Sentinel
|
|
|
|
Control Groups are also supported in Sentinel policies using the `controlgroup`
|
|
import. See [Sentinel Documentation](/docs/enterprise/sentinel) for more
|
|
details on available properties.
|
|
|
|
### Sample Sentinel Policy
|
|
|
|
```
|
|
import "time"
|
|
import "controlgroup"
|
|
|
|
control_group = func() {
|
|
numAuthzs = 0
|
|
for controlgroup.authorizations as authz {
|
|
if "managers" in authz.groups.by_name {
|
|
if time.load(authz.time).unix > time.now.unix - 3600 {
|
|
numAuthzs = numAuthzs + 1
|
|
}
|
|
}
|
|
}
|
|
if numAuthzs >= 2 {
|
|
return true
|
|
}
|
|
return false
|
|
}
|
|
|
|
main = rule {
|
|
control_group()
|
|
}
|
|
```
|
|
|
|
The above policy will reject the request unless two members of the `managers`
|
|
group have authorized the request. Additionally it verifies the authorizations
|
|
happened in the last hour.
|
|
