Access Control Entry. It describes access permission
associated with a particular ACE ID.
There are three ACE frame types (Ethernet Type, ARP, and
IPv4) and two ACE actions (permit and deny). ACE also
contains many detailed, different parameter options that are
available for individual application.
Access Control List. It is the list table of ACEs, containing
access control entries that specify individual users or groups
permitted or denied to specific traffic objects, such as a process
or a program. Each accessible traffic object contains an
identifier to its ACL. The privileges determine if there are
specific traffic object access rights.
In networking, the ACL refers to a list of service ports or network
services that are available on a host or server, each with a list of
hosts or servers permitted or denied to use the service. ACL
can generally be configured to control inbound traffic, and in this
context, they are similar to firewalls.
