What Is a Network ACL?Region Type I: A network ACL is a virtual private cloud security service. It controls access to subnets and supports blacklists and whitelists (allow rules and deny rules). Based on the inbound and outbound Access Control List (ACL) rules associated with subnets, the...
Network protocol: The network protocol can be used to permit or deny certain networking protocols, such as IP, Internetwork Packet Exchange (IPX), Transmission Control Protocol (TCP), Internet Control Message Protocol (ICMP), User Datagram Protocol (UDP), or others. Source or destination: The so...
In this way, ACL ensures security and high service quality on networks. Figure 1-1 shows a typical network with ACL configured. Figure 1-1 ACL application scenario To ensure financial data security, access to the financial server is allowed only from the president office; access from the R&D...
An ACL is directly configured in a device’s forwarding hardware, so it does not affect the performance. A firewall can perform more advanced inspection, but it can compromise the network’s performance. How Can I Configure an ACL on a Switch?
Why Is an ACL Used? An Access Control List (ACL) acts as a crucial filter, enabling devices to manage and control specific incoming and outgoing traffic. Without the use of ACLs, the network is left vulnerable to potential attacks. In the following scenario, an enterprise employs an ACL on...
Figure 1-1shows a typical network with ACL configured. Figure 1-1ACL application scenario To ensure financial data security, access to the financial server is allowed only from the president office; access from the R&D department to the financial server is blocked. The implementation method is as...

Network ACL resources are classified into groups, policies, and rules.The relationships among them are as follows:A network ACL policy can be associated with multiple net
computational overhead than stateful firewalls and that they work at high speeds. This is essential when you try to implement security for fast network interfaces. However, the longer a packet remains in the system, while it is examined against the rules in the ACL, the slower the performance...
User ACL The terminals of employees in the same department of an enterprise are located on different network segments and are difficult to manage. To facilitate their access permission management, you need to add them to a user group. In this case, a user ACL is required. Compared with an ...
