Overview

Using this API, You can manage NTFS file security and audit policies of file or directory without the need of a client. It works similar to what you could do with a cacls in windows client. It will create an NTFS security descriptor(SD) to which you can add access control entries (ACEs) to the discretionary access control list (DACL) and the system access control list (SACL). Generally, an SD contains following information:

• Security identifiers (SIDs) for the owner and primary group of an object. A security identifier (SID) is a unique value of variable length used to identify a trustee. Each account has a unique SID issued by an authority, such as a Windows domain controller, and is stored in a security database.
• A DACL identifies the trustees that are allowed or denied access to a securable object. When a process tries to access a securable object, the system checks the ACEs in the object's DACL to determine whether to grant access to it.
• A SACL enables administrators to log attempts to access a secured object. Each ACE specifies the types of access attempts by a specified trustee that cause the system to generate a record in the security event log. An ACE in a SACL can generate audit records when an access attempt fails, when it succeeds, or both.
• A set of control bits that qualify the meaning of a SD or its individual members.

Currently, in ONTAP CLI, creating and applying NTFS ACLs is a 5-step process:

• Create an SD.
• Add DACLs and SACLs to the NTFS SD. If you want to audit file and directory events, you must configure auditing on the Vserver, in addition, to adding a SACL to the SD.
• Create a file/directory security policy. This step associates the policy with a SVM.
• Create a policy task. A policy task refers to a single operation to apply to a file (or folder) or to a set of files (or folders). Among other things, the task defines which SD to apply to a path.
• Apply a policy to the associated SVM.

This REST API to set the DACL/SACL is similar to the windows GUI. The approach used here has been simplified by combining all steps into a single step. The REST API uses only minimal and mandatory parameters to create access control entries (ACEs), which can be added to the discretionary access control list (DACL) and the system access control list (SACL). Based on information provided, SD is created and applied on the target path.

Examples

Creating a new SD

Use this endpoint to apply a fresh set of SACLs and DACLs. A new SD is created based on the input parameters and it replaces the old SD for the given target path:

Adding a single DACL/SACL ACE

Use this endpoint to add a single SACL/DACL ACE for a new user or for an existing user with a different access type (allow or deny). The given ACE is merged with an existing SACL/DACL and based on the type of “propagation-mode”, it is reflected to the child object:

from netapp_ontap import HostConnection
from netapp_ontap.resources import FileDirectorySecurityAcl

with HostConnection(

Updating existing SACL/DACL ACE

Use this endpoint to update the rights/advanced rights for an existing user, for a specified path. You cannot update the access type using this end point. Based on the type of “propagation-mode”, it is reflected to the child object:

with HostConnection(
    "10.140.101.39", username="admin", password="password", verify=False

    resource.advanced_rights.read_data = False
    resource.advanced_rights.read_ea = False
    resource.advanced_rights.read_perm = False
    resource.advanced_rights.write_attr = True
    resource.advanced_rights.write_data = True
    resource.advanced_rights.write_ea = True
    resource.advanced_rights.write_owner = True

    resource.ignore_paths = ["/parent/child2"]
    resource.propagation_mode = "propagate"
    resource.patch(hydrate=True, return_timeout=0)

Deleting existing SACL/DACL ACE

Use this endpoint to delete any of the existing rights/advanced_rights for a user. Based on the type of “propagation-mode”, it is reflected to the child object:

from netapp_ontap import HostConnection
from netapp_ontap.resources import FileDirectorySecurityAcl

with HostConnection(
    "10.140.101.39", username="admin", password="password", verify=False
):
    resource = FileDirectorySecurityAcl("/parent", user="himanshu")
    resource.delete(
        body={
            "access": "access_allow",
            "apply_to": {"files": True, "sub_folders": True, "this_folder": True},
            "ignore_paths": ["/parent/child2"],
            "propagation_mode": "propagate",
        },
        return_timeout=0,
    )

Classes

class FileDirectorySecurity (*args, **kwargs)

Manages New Technology File System (NTFS) security and NTFS audit policies.

Initialize the instance of the resource.

Any keyword arguments are set on the instance as properties. For example, if the class was named 'MyResource', then this statement would be true:

MyResource(name='foo').name == 'foo'

Args

*args

Each positional argument represents a parent key as used in the URL of the object. That is, each value will be used to fill in a segment of the URL which refers to some parent object. The order of these arguments must match the order they are specified in the URL, from left to right.

**kwargs

each entry will have its key set as an attribute name on the instance and its value will be the value of that attribute.

Ancestors

• Resource

Static methods

def patch_collection(body: dict, *args, connection: HostConnection = None, **kwargs) -> NetAppResponse

Updates SD specific Information i.e owner, group & control-flags

Learn more

• DOC /protocols/file-security/permissions/{svm.uuid}/{path}

---

Args

body

A dictionary of name/value pairs to set on all matching members of the collection.

*args

Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to patch the collection of bars for a particular foo, the foo.name value should be passed.

connection

The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.

**kwargs

Any key/value pairs passed will be sent as query parameters to the host. Only resources matching this query will be patched.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

NetAppRestError: If the API call returned a status code >= 400

Methods

def get(self, **kwargs) -> NetAppResponse

Retrieves file permissions

Learn more

• DOC /protocols/file-security/permissions/{svm.uuid}/{path}

---

Requires the keys to be set (if any). After returning, new or changed properties from the host will be set on the instance.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

NetAppRestError: If the API call returned a status code >= 400

Args

hydrate

If set to True, after the response is received from the call, a a GET call will be made to refresh all fields of the object.

poll

If set to True, the call will not return until the asynchronous job on the host has completed. Has no effect if the host did not return a job response.

poll_interval

If the operation returns a job, this specifies how often to query the job for updates.

poll_timeout

If the operation returns a job, this specifies how long to continue monitoring the job's status for completion.

Any key/value pairs passed will normally be sent as query parameters to the host. If any of these pairs are parameters that are sent as formdata then only parameters of that type will be accepted and all others will be discarded.

Returns

A NetAppResponse object containing the details of the HTTP response.
