@ohos.enterprise.securityManager (Security Management) (System API)

The securityManager module provides device security management capabilities, including obtaining the security patch status and file system encryption status.

NOTE

The initial APIs of this module are supported since API version 11. Newly added APIs will be marked with a superscript to indicate their earliest API version.

The APIs of this module can be used only in the stage model.

The APIs of this module can be called only by a device administrator application that is enabled.

This topic describes only the system APIs provided by the module. For details about its public APIs, see @ohos.enterprise.securityManager.

Modules to Import

import { securityManager } from '@kit.MDMKit';

securityManager.getSecurityPatchTag

getSecurityPatchTag(admin: Want): string

Queries the security patch tag of a device.

Required permissions: ohos.permission.ENTERPRISE_MANAGE_SECURITY

System capability: SystemCapability.Customization.EnterpriseDeviceManager

System API: This is a system API.

Parameters

Name	Type	Mandatory	Description
admin	Want	Yes	EnterpriseAdminExtensionAbility.

Return value

Type	Description
string	Patch tag obtained.

Error codes

For details about the error codes, see Enterprise Device Management Error Codes and Universal Error Codes.

ID	Error Message
9200001	The application is not an administrator application of the device.
9200002	The administrator application does not have permission to manage the device.
201	Permission verification failed. The application does not have the permission required to call the API.

import { Want } from '@kit.AbilityKit';

let wantTemp: Want = {
  bundleName: 'com.example.myapplication',
  abilityName: 'EntryAbility',
};

try {
    let res: string = securityManager.getSecurityPatchTag(wantTemp);
    console.info(`Succeeded in getting security patch tag. tag: ${res}`);
} catch(err) {
    console.error(`Failed to get security patch tag. Code: ${err.code}, message: ${err.message}`);
}

getDeviceEncryptionStatus(admin: Want): DeviceEncryptionStatus

Queries the encryption status of the device file system.

Required permissions: ohos.permission.ENTERPRISE_MANAGE_SECURITY

System capability: SystemCapability.Customization.EnterpriseDeviceManager

System API: This is a system API.

Parameters

Name	Type	Mandatory	Description
admin	Want	Yes	EnterpriseAdminExtensionAbility.
