Router access list is the list of condition that categorize packet and also filter unwanted packets.
And at 1 interface per direction, per protocol there should be only 1 ACL.
ACL list are of two types
Standard and Extended
In Number standard ACL range is 1-99, 1300-1999.
In Number standard ACL range is 100-199, 2000-2699.
What else can I help you with?
Are standard access listS confIgured close to the source or destination address?
Standard access lists are placed close to the destination. Extended access list are placed close to the source. This is because extended ACL's look at the source and destination IP address, whereas standard ACL's look at the source IP address only.
Which statements describe characteristics of extended access lists?
They check packets by source address They check packets by destination address
How do named access lists differ from standard access lists?
Named access lists can be identified by alphanumeric names while standard access lists cannot
On a Cisco router x IP lists check source packet addresses while y IP access lists check for both source and destination packet addresses?
x -> standard y -> extended
How do extended access control list differ from standard access control list?
Standard Access Control Lists (ACLs) only allows you to permit or deny source addresses. You can not block based on protocol, port, or destination. Extended ACLS allow you to block traffic based on source address, destination address, source port, destination port, and protocol.
What are the key differences between access control lists and capability lists in terms of controlling access to resources?
Access control lists (ACLs) are a list of permissions attached to an object that specify which users or groups are granted access to that object. Capability lists, on the other hand, are a list of permissions attached to a user that specify what resources that user can access. The key difference is that ACLs control access based on the object, while capability lists control access based on the user.
Disadvantage of linked lists?
The access time for items is proportional to the distance they are from the end of the list which can become very time consuming for long lists.
Which of the following guidelines for using access lists are valid?
Remove lines selectively when using named IP access lists Make subsequent additions at the end of the access list Every access list should have at least one permit statement
How many access lists can be applied per protocol?
one
With the discretionary access control model the most common control implementation is through?
access control lists
In order to gain illegitimate access to a network attackers often by-pass access control lists by .?
Spoofing
When accessing an object what lists each user that can access the object and what each user can do with the object?
Access Control List (ACL) lists each user that can access the object and specifies their permissions, such as read, write, or execute. It enforces security policies by determining who can access the object and what actions they can perform.
