In the Java ACL model, a user may need to request a specific data operation. The ACL checks its entries to determine user permissions and if the user is authorized, the user may perform the operation. The ACL is a guard that grants or denies access permission by acting on contained data entries.
Java ACL may be explained with the following example: An individual named John wants to delete a particular piece of data. When John makes a request to delete the data, the ACL checks its entries to verify whether or not John may perform this action. If an entry confirms that John is authorized, John may delete the data. If John does not have the appropriate user permission, he is unable to perform the deletion and is denied access.
