ACE: Access Control Entry

ACE is an abbreviation of "Access Control Entry".

It is a particular distinct term included inside an ACE that includes information about the user or group and the related permissions. Every entry, which is an access control entry in a distinctive ACE, indicates a subject and an operation. An ACE is an abbreviation of the access-control list, concerning a computer file system, which is a record list of access control entries permissions put together with an object. An ACE indicates through access control entry, which users or system processes are approved accesses to objects, at the same time what operations are enabled on specified objects.

For Example:

In the case of a situation, if a file object has an ACE that includes access control entries (Amber: read, write; John: read), this would provide Amber access control entry of permission to read and write the file and John to only read it.
Implementations

Various types of operating systems implement ACEs, through which they provide access control entries of several pieces of information and their related permissions, or have a chronological implementation from the past, which comprise:

Filesystem ACEs

  1. A filesystem ACE is a data structure, generally, a table, which comprises entries that indicate individual user or group rights to particular system objects such as programs, processes, or files.
  2. These entries are known as access control entries (ACEs) in the Microsoft Windows NT, OpenVMS, Unix-like, and Mac OS X operating systems.
  3. Each available and reachable object comprises an identifier to its ACE.

Active Directory ACEs

  1. Microsoft's Active Directory Service implements an LDAP server that accumulates and spread widely configuration information about users and computers in a domain through access control entry.
  2. Active Directory expands the LDAP specification by adding up together the similar category of access-control list mechanism as Windows NT uses for the NTFS filesystem.

Networking ACEs

  1. On a variety of categories of proprietary computer-hardware, specifically routers and switches, an access-control list makes an available set of rules for an access control entry permission that are applied to port numbers or IP addresses that are available on a host or other layer 3, each with a list of hosts and/or networks allowed to use the service.
  2. Even though it is furthermore probable to configure access-control lists by getting access control entries permissions based on network domain names, this is open to discussion idea for the reason that individual TCP, UDP, and ICMP headers do not comprise domain names.

SQL implementations

  1. ACE algorithms have been ported to SQL and relational database systems.
  2. A lot of "modern" (2000s and 2010s) SQL-based systems, like enterprise resource planning and content management systems, have used ACE models and their access control entry features in their administration modules.
