What is Cisco zone-based firewall?

The Cisco Zone-Based Firewall is the successor of Classic IOS firewall or CBAC (Context-Based Access Control). It primarily deals with the security “zones”. We can assign router interfaces to various security zones and control the traffic between them. The firewall dynamically inspects traffic passing through zones.

What is a zone based policy firewall?

Zone-Based Policy Firewall (also known as Zone-Policy Firewall, or ZFW) changes the firewall configuration from the older interface-based model to a more flexible, more easily understood zone-based model. Interfaces are assigned to zones, and inspection policy is applied to traffic moving between the zones.

How does zone-based firewall work?

With a zone-based firewall solution, zones are created for each part of the network that required different access/traffic control policies. These zone-pairs are unidirectional and are configured with a specific traffic policy that is used when traffic passes from the source zone to destination zone.

Is checkpoint a zone-based firewall?

With the invention of Check Point’s layer based approach, zone-based firewall technology has taken a step forward into controlling access. Check Point introduced inline layers with a concept of parent and child rules.

What is difference between ACL and firewall?

A firewall has one main use and purpose and that is to examine traffic passing through a part of the network and make decisions about what to let through and what to block. ACLs do stateless inspection, which means that the access list looks at a packet and has no knowledge of what has come before it.

How many zones does a firewall have?

Generally speaking, a standard firewall implementation involves separating trusted traffic and untrusted traffic. Proper firewall implementation creates two basic security zones, known as inside and outside. The inside or trusted zone is also referred to as the private zone.

How do I create a zone in my firewall?

Zone-based Firewall procedure:

1. Create zones and assign an interface to it – In Zone-based firewall, logical zones are created.
2. Create class-map –
3. Create policy-map and assign class-map to the policy-map –
4. Configure a zone-pair and assign the policy –

How do you set a zone in firewall?

How do I create a zone in Checkpoint firewall?

Does firewall use ACL?

Firewalls use ACLs to filter traffic. By configuring different rules in the ACL you change the behavior of the firewall. Software firewalls do also exist (windows firewall) but the behavior is much the same. It still has its own ACL that allows or denies traffic based on source, destination, and port.

What is the difference between an IPS and a firewall?

An IPS will inspect content of the request and be able to drop, alert, or potentially clean a malicious network request based on that content. A firewall will block traffic based on network information such as IP address, network port and network protocol. …

What are the three zones of firewall?

Although, we can give any name but by naming convention that makes sense, name the zones as inside, outside and DMZ.

• inside: The most trusted (private) network.
• outside: The most untrusted (public) network.
• DMZ: (public zone) contains devices like servers.

Is the Cisco zone based policy firewall compatible with WAAS?

The general guideline is that you should group interfaces that are similar when they are viewed from a security perspective. The Wide Area Application Services (WAAS) and Cisco IOS firewall interoperability capability applies only on the Zone-Based Policy Firewall feature in Cisco IOS Release 12.4 (11)T2 and later releases.

How to create zone-based security policy firewall?

A security zone is a group of interfaces to which a policy can be applied. Grouping interfaces into zones involves two procedures: Creating a zone so that interfaces can be attached to it. Configuring an interface to be a member of a given zone.

Is the Cisco IOS XE firewall compatible with WCCP?

In a WAAS and Cisco IOS XE firewall configuration, WCCP does not support traffic redirection using policy-based routing (PBR). WCCP traffic redirection does not work when zone-based policy firewall enabled with generic GRE is configured on a Cisco Aggregation Services Router that is configured with Cisco AppNav I/O modules.

Is the perfilter available in zone based firewalls?

Perfilter statistics is available in zone-based firewalls from Cisco IOS XE Release 3.13S and later releases. Bridge domain interfaces do not support zone-based firewall inspection, including all Layer 4 and Layer 7 inspection.
