⚡ CоmpTIA Netwоrk+ PBQ 5: Firewаll Access Cоntrol List (ACL) Hаrdening You must hаrden an enterprise perimeter firewall protecting three security zones: Outside (Internet), DMZ (192.168.50.0/24), and Internal LAN (10.10.0.0/16). Security policy mandates: 1. Permit inbound Internet traffic to access the DMZ Web Server (192.168.50.10) exclusively over encrypted HTTPS. 2. Permit the internal IT Admin subnet (10.10.100.0/24) to manage DMZ appliances exclusively over encrypted SSH. 3. Explicitly deny and log legacy unencrypted cleartext protocols (Telnet and HTTP) from all sources. 4. Enforce the principle of least privilege with a default termination rule. Configure the Access Control List (ACL) rules: Rule 10 (Public Web Traffic): - Action: [pbq5_r1_act] - Destination IP: [pbq5_r1_dst] - Destination Port: [pbq5_r1_port] Rule 20 (Secure IT Administration): - Action: [pbq5_r2_act] - Destination IP: [pbq5_r2_dst] - Destination Port: [pbq5_r2_port] Rule 30 (Block Legacy Cleartext Traffic): - Action: [pbq5_r3_act] - Blocked Destination Ports: [pbq5_r3_port] - Intent Description: [pbq5_r3_desc] Rule 999 (Default Posture): - Action: [pbq5_r4_act] - Source: [pbq5_r4_src] - Destination: [pbq5_r4_dst]
