Controlling traffic at the packet level is essential for both security and performance. These labs dive into Access Control Lists (ACLs), showcasing how to filter and manage traffic using both standard and extended ACL configurations. From permitting or denying traffic based on IP addresses, subnets, and port numbers to applying ACLs inbound and outbound on interfaces, each scenario reflects real-world use cases in securing network boundaries. These exercises highlight my ability to implement precise traffic control policies that protect network resources and enforce access rules.
Access Control Lists
Configured and applied standard and extended ACLs on router interfaces to enforce network communication restrictions across subnets. Implemented traffic filters to block DNS, HTTP, and HTTPS access based on source and destination IPs and ports, simulating realistic enterprise security controls.
