There are certain guidelines that you must keep in mind before applying file-directory policies on the storage virtual machine (SVM) disaster recovery destination in an ID discard configuration if your file-directory policy configuration uses local users or groups in either the security descriptor or the DACL or SACL entries. Guidelines for applying file-directory policies that use local users or groups on the SVM disaster recovery destination.Security descriptors contain the access control lists that determine what actions a user can perform on files and folders, and what is audited when a user accesses files and folders. How security descriptors are used to apply file and folder security.You need to be aware of certain limits when using the CLI to set file and folder security. Limits when using the CLI to set file and folder security.Use cases for using the CLI to set file and folder securityīecause you can apply and manage file and folder security locally without involvement from a remote client, you can significantly reduce the time it takes to set bulk security on a large number of files or folders.Therefore, Storage-Level Access Guard provides an extra layer of security for data access that is independently set and managed by the storage administrator. Storage-Level Access Guard security cannot be revoked from a client, even by a system (Windows or UNIX) administrator. Moreover, if you view the security settings on a file or directory from an NFS or SMB client, you will not see the Storage-Level Access Guard security. You cannot manage Storage-Level Access Guard settings from SMB clients. Storage-Level Access Guard can be configured and managed only from the ONTAP CLI. Storage-Level Access Guard applies to accesses from all NAS protocols to the storage object to which Storage-Level Access Guard is applied. You can configure Storage-Level Access Guard, which is another layer of security applied by ONTAP to SVM volumes. Using the CLI can significantly reduce the time it takes to apply security on many files and folders using a single command. However, using the CLI to configure file security and audit policies removes the need to use a remote client to manage file security. You can manage NTFS file security and audit policies from SMB clients or by using the CLI. You can manage NTFS file security, NTFS audit policies, and Storage-Level Access Guard on storage virtual machines (SVMs) by using the CLI.
