ACLs are lists applied to routers to control network access by filtering packets based on conditions like source/destination addresses, protocols, and port numbers. They can limit traffic to increase performance, provide traffic flow control, and provide basic network security. There are standard and extended ACLs, with extended ACLs providing more granular control by checking source/destination addresses and specific protocols and ports. Basic rules for ACLs include applying standard ACLs near the destination and extended ACLs near the source, processing entries sequentially from top to bottom, and filtering from specific to general.

Access control list [1]
Access control lists (ACLs) can be used for filtering and identifying network traffic. ACLs are composed of rules that either permit or deny traffic based on conditions like source/destination addresses, protocols, and port numbers. Numbered ACLs range from 1-99 for standard IP and 100-199 for extended IP. Named ACLs have no number limit. Standard ACLs filter based only on source IP while extended ACLs examine both source and destination addresses, protocol, and port numbers.
Access Control List & its Types
Access Control List (ACLs) can be used for two purposes:
1. To filter traffic
2. To identity traffic
Access lists are set of rules, organized in a rule table. Each rules or line in an access-list provides a
condition, either permit or deny.
Types of ACLs
There are two types of access control lists (ACLs): standard ACLs and extended ACLs. Standard ACLs filter based only on the source IP address and are less processor intensive, while extended ACLs allow filtering on source/destination IP addresses, protocols, and ports to provide more granular control but require more processing power. Both can be used to restrict access to sensitive servers and resources like allowing only management network users to access an important documents server.

- Access control lists (ACLs) allow or deny network traffic passing through a router based on source and destination IP addresses, protocols, and port numbers.
- There are two main types of ACLs: standard ACLs which filter based on source IP addresses, and extended ACLs which filter on source/destination IP addresses, protocols, and port numbers.
- ACLs can be numbered or named, with named ACLs allowing selective editing of statements not possible with numbered ACLs.
Basic ip traffic management with access control lists
The document discusses basic concepts of access control lists (ACLs) including the types of ACLs, how they are configured and used, and how traffic is processed when ACLs are applied. It provides details on standard and extended ACLs, how they can be used to filter traffic by source/destination IP addresses, protocols, ports and ICMP message types. The document also covers best practices for verifying, monitoring and placing ACLs on network interfaces.
Standard & Extended ACL Configuration
The document is a lab report that describes configuring standard and extended access control lists (ACLs) in a computer network. It defines standard ACLs as using only source IP addresses to permit or deny all protocol traffic between an entire network or sub-network. Extended ACLs can distinguish different protocol traffic like TCP, UDP, and HTTPS using source/destination IP addresses and port numbers to permit or deny specific services. The report provides examples of configuring a standard ACL to deny all traffic from one subnet and an extended ACL to deny traffic between a specific host and server.

CCNA part 7 acl
ACL (Access Control List) is a layer 3 security feature that controls traffic flow between routers by matching packets based on various criteria like source/destination IP addresses, protocols, and port numbers. There are standard, extended, and named ACLs that provide different matching capabilities. ACLs are configured on router interfaces using access lists and access groups to filter inbound or outbound traffic.

10 module
The document discusses using access lists to filter IP traffic passing through a router. It describes the different types of access lists (standard and extended), how to configure them to allow or deny traffic based on source/destination addresses and protocols, and how to apply them to interfaces to filter incoming or outgoing traffic.
Extended Access Lists
Extended access lists allow filtering of traffic based on source and destination IP addresses and port numbers. The document provides an example of an extended access list configured on Router R1 to deny HTTP requests from client PC 10.0.0.2 to web server 10.0.1.2. It also shows another example using subnets to deny telnet access. Finally, it demonstrates how to configure a named extended access list to filter both HTTP and telnet traffic from the client PC.
Configuring extended ACLs
Extended access lists allow for more precise matching of network traffic than standard access lists by allowing specification of source/destination IP addresses, protocol, and port numbers. Two steps are required to configure an extended ACL: 1) use the access list command to define permit/deny rules and 2) apply the ACL to an interface. Extended ACLs can be used to allow certain users to access specific servers by IP and port while denying other traffic.

Ip Access Lists
Access lists allow routers to filter packets and are supported for several protocols like IP, Ethernet, and IPX. Access lists contain rules that either permit or deny traffic from and to particular sources and destinations. These lists are applied to router interfaces to filter traffic as it passes through. Extended access lists offer more granular control than standard lists by allowing filtering based on transport protocol, port, and source/destination addresses.
API
An API allows programmers to use commands and functions to build software for a specific operating system. It defines how programs interact with the OS. Sockets provide endpoints for two-way communication between programs over a network using an IP address and port number combination. The document then provides code examples of a simple server and client program using sockets and APIs to communicate by sending and receiving a string. It discusses two process models for networking - process-per-protocol which uses separate processes for each protocol layer, and process-per-message which treats each protocol as static code and associates processes with individual messages.

Chapter 08 - Acl
ACLs control and manage network traffic by allowing or denying packet access based on conditions. Standard ACLs are used to filter traffic by source IP address only, while extended ACLs filter by source/destination IP address, protocols, and ports. ACLs are created with permit or deny statements and applied to interfaces using access lists or to virtual terminal lines using access classes to restrict access. Wildcard masks are used to filter groups of IP addresses in an access list.

SEC450 ACL Tutorial
This document highlights the most important concepts on Access Control List (ACL) that
you need to learn in order to configure ACL in CLI. This tutorial does not intend by any
mean to cover all ACL applications, but only those scenarios used in then SEC450
iLabs.
Introduction to Access Control List
A host-based firewall essentially works closing and/or opening ports in a
computer. The engine behind firewalls is built with Access Control Lists (ACL).
Network-based firewalls are implemented in device-specific appliances and
routers. Basically, firewalls in routers filter packets through interfaces to permit
or deny them.
Ports are layer-4 address specified in TCP/IP protocol suit that identify
networking processes running in clients and servers.
ACLs are configured using shell-specific commands. In Cisco IOS, CLI
commands access-list and access-group are used to create and apply ACL on
an interface.
ACL can be named by number ID or a name. Naming ACL is useful to identify
ACL’s purpose.
ACL are classified in Standard ACL, and Extended ACL.
Standard ACL’s number IDs are assigned from 1 to 99. Extended ACL’s number
IDs are from 100 to 199.
Standard ACL only uses source IP address in an IP packet to filter through an
interface. Hence, standard ACL denies or permits all packets (IP) with the same
source IP regardless upper protocols, destination IP address, etc. Example 1:
Router(config)#access-list 8 deny host 172.12.3.5
Extended ACL does filtering packets based on protocol, source IP address,
source port number, destination IP address and destination port number.
Example 2: Router(config)#access-list 102 deny tcp host 10.0.3.2 host
2
172.129.4.1 Deny tcp packets with source IP address 10.0.3.2 and destination IP
address 172.129.4.1.
Since, Standard ACLs only have source IP address; the rule is to apply them in
an interface as closer as possible to the concerning destination network.
For the contrary, the rule for Extended ACLs is to apply them in an interface as
closer as possible to the source IP address.
Use Extended ACL in all iLabs as they are more granular on packets to filter.
Create Extended ACL in global configuration
You can use access-list command options lt, gt, eq, neq, range (less than,
greater than, equal, not equal, range of ports) to do operation with port numbers.
Example 3: access-list 102 deny tcp any host 11.23.45.7 gt 20 denies all
packets with any source IP address to destination IP address 11.23.45.7 and
destination tcp port greater than 20.
Example 4: access-list 107 permit udp any any permits all packets with udp
protocol with any source IP address to any destination IP address.
Extended ACL can do packet filtering based on source port number and
destination port number.
Extended ACL Syntax can be as follows:
access-list <#,name> <protocol> ...

SEC450 ACL Tutorial
This document highlights the most important concepts on Access Control List (ACL) that
you need to learn in order to configure ACL in CLI. This tutorial does not intend by any
mean to cover all ACL applications, but only those scenarios used in then SEC450
iLabs.
Introduction to Access Control List
A host-based firewall essentially works closing and/or opening ports in a
computer. The engine behind firewalls is built with Access Control Lists (ACL).
Network-based firewalls are implemented in device-specific appliances and
routers. Basically, firewalls in routers filter packets through interfaces to permit
or deny them.
Ports are layer-4 address specified in TCP/IP protocol suit that identify
networking processes running in clients and servers.
ACLs are configured using shell-specific commands. In Cisco IOS, CLI
commands.

access control list(ACL) from data communication and networking
Access control lists (ACLs) allow network administrators to control network access by denying unwanted traffic while permitting necessary internal access. ACLs provide more flexible traffic filtering than general security tools through lists that sequentially permit or deny addresses, protocols, ports and other criteria. For example, an administrator can use an ACL to allow user Internet access but block external telnet access to the internal network. Standard ACLs filter based on source IP addresses and are applied near destinations, while extended ACLs can also filter destination addresses, protocols and port numbers and are applied near sources.
CCNA ppt Day 7
ACLs (Access Control Lists) are used to control network traffic through routers by permitting or denying traffic based on conditions like source/destination IP addresses. There are two types: standard ACLs filter based on source IP and are configured on destination routers, while extended ACLs filter on source/destination IP and can block specific protocols. NAT (Network Address Translation) converts private IP addresses to public IP addresses to avoid IP address depletion and implement network security through configurations like static, dynamic, or port address translation which maps private ports to a public IP address.

Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).

Editor's Notes
- Layer 2 of 2 Emphasize: An access list is a mechanism for identifying particular traffic. One application of an access list is for filtering traffic into or out of a router interface.
- Permission for router Manage IP Traffic Filter packet which pas thru Either can permit or Deny
- If u want to permit only one from a network then permit shud be first
- Layer 3 of 3 Purpose: Describe an inbound versus outbound access list on an interface.
- Layer 3 of 3 Emphasize: Layer 3—Adds the Novell IPX access lists covered in Chapter 11, “Configuring Novell IPX,” and the number ranges for these types of access lists. As of Release 11.2.4(F), IPX also supports named access lists. Point out that number ranges generally allow 100 different access lists per type of protocol. When a given hundred-number range designates a standard access list, the rule is that the next hundred-number range is for extended access lists for that protocol. Exceptions to the numbering classification scheme include AppleTalk and DECnet, where the same number range can identify various access list types. For the most part, number ranges do not overlap between different protocols. Note: With Cisco IOS 12.0, the IP access-lists range has been expanded to also include: <1300-1999> IP standard access list (expanded range) <2000-2699> IP extended access list (expanded range)
