An access control list (ACL) is a
mechanism you can use to define who has access to your buckets and objects, as
well as what level of access they have.
In other words, an access control
list (ACL) is a table that tells a computer operating system which access
rights each user has to a particular system object, such as a file directory or
individual file. Each rule or line in an access-list provides a condition,
either permit or deny.
Access control lists
(ACLs) can be used for two purposes on Cisco devices:
1. To filter traffic
2. To identify traffic
There are two types of
ACL:
1. Standard
2. Extended
Numbered access lists
are broken down into several ranges, each dedicated
to a specific
protocol:
Range of both ACL
1–99 IP standard access list
100-199 IP extended access list
1300-1999 IP standard access list
(expanded range)
2000-2699 IP extended access list
(expanded range)
Named access lists
Named access lists provide a bit
more flexibility. Descriptive names can be used to identify your access-lists.
Additionally, individual lines can be removed from a named access-list.
However, like numbered lists, all new entries are still added to the bottom of
the access list.
There are two common
types of named access lists:
IP standard named access lists
IP extended named access lists
