- Zone-Based Policy Firewalls 5 step process - Cisco Learning Network
My example PMAP action will be to inspect the class map Here you can also define the policy action to pass or drop traffic Step 5 you will create a service policy by naming it and identifying the flow in which traffic is going and identifying the zone membership (zone-membership) and use the names of the zones we created
- Zone Based Firewall Part 1 - Cisco Learning Network
Zone-Based Policy Firewall (ZBPF) (Zone Based Firewall) is the successor of Cisco IOS Legacy Firewall called (CBAC) Context-Based Access Control Concept of ZBPF is zone, which groups different interfaces sharing the same security attributes or the same level of trust Permissions for traffic forwarding is made between the zones or within a zone, not between physical interfaces
- IPSec Traffic Through Cisco ASA: Understanding NAT and Inspection Scenarios
Conditions: ASA is doing NAT ASA is configured with inspect ipsec-pass-thru Required Configuration: Enable IPSec inspection on ASA Allow UDP 500 on outside interface (if R7 is initiator) What Happens: ASA inspects ISAKMP (UDP 500) negotiations ASA dynamically opens holes for ESP and or UDP 4500 based on negotiation Benefit:
- Question about ZPF with the TFTP protocol - Cisco Learning Network
I tried a class-map: class-map type inspect match-any USERS_ACCESS match protocol icmp match protocol tcp match protocol udp match protocol tftp Does the order matter? And should I use: class-map type inspect match-any USERS_ACCESS match protocol tftp match protocol icmp match protocol tcp match protocol udp I'm not at the lab right now so I can't try it Maybe tomorrow morning
- ASA Default Inspection - Cisco Learning Network
Hi Atul, Inspection refers to the ASA's ability to look inside the configured protocols and perform certain actions based on the 'controlplane' traffic found in the traffic flow The ASA has an understanding of the protocols it can inspect Some protocols, such as FTP, can dynamically open additional ports for data transfer The inspection is not required as such, but some protocols won't work
- policy map - Cisco Learning Network
What is the differnce between policy-map type inspect preset_dns_map what does it mean by inspect command ? If i have inspect dns command do i need again "policy-map type inspect dns preset_dns_map" policy-map type inspect dns preset_dns_map parameters message-length maximum client auto message-length maximum 512
- Class Map [match default-inspection-traffic]
Hi Atul, Sure you can do that By default, class-map inspection_default is assigned to global_policy policy-map and to view the protocols inspected by default on ASA use following command ASA1# sh run policy-map global_policy ! policy-map global_policy class inspection_default inspect dns preset_dns_map inspect ftp inspect h323 h225 inspect h323 ras inspect rsh inspect rtsp inspect esmtp
- IP Inspects -- Why do we need them? - Cisco Learning Network
ip inspect name FWOUT udp ip inspect name FWOUT icmp ip inspect name FWOUT ftp This will tell our IOS firewall to properly inspect and handle ftp traffic In other words, this adds the some specific protocol intelligence that is required to handle ftp What about other protocols, like SMTP? Shouldn’t that work since there are no secondary
