What is zone-based firewall?

What is zone-based firewall?

A Zone-based firewall is an advanced method of the stateful firewall. In a stateful firewall, a stateful database is maintained in which source IP address, destination IP address, source port number, destination port number is recorded.

Which two rules about interfaces are valid when implementing a zone based policy firewall?

If both interfaces belong to the same zone-pair and a policy exists, all traffic will be passed. If both interfaces are members of the same zone, all traffic will be passed. If one interface is a zone member and a zone-pair exists, all traffic will be passed.

Is Cisco ASA zone based firewall?

Even though ASA devices are considered as the dedicated firewall devices, Cisco integrated the firewall functionality in the router which in fact will make the firewall a cost effective device. The zone based firewall came up with many more features that is not available in CBAC.

How does a zone based firewall implementation handle traffic between interfaces in the same zone?

Traffic between interfaces in the same zone is blocked unless you configure the same security permit command. C. Traffic between interfaces in the same zone is always blocked.

How do I set destination NAT in Checkpoint firewall?

Create a manual NAT rule that translates HTTP traffic from the Security Gateway to the web server.

1. In SmartConsole, go to Security Policies > Access Control > NAT.
2. Add a rule below the automatic rules.
3. Right-click the cell and select Add new items to configure these settings: Original Destination – Alaska_GW.

Which two rules about interfaces are valid when implementing a zone Basedpolicy firewall choose two?

Which two rules about interfaces are valid when implementing a Zone-Based Policy Firewall? (Choose two.) If neither interface is a zone member, then the action is to pass traffic. If one interface is a zone member, but the other is not, all traffic will be passed.

What is zone-based firewall Palo Alto?

It is without doubt Zone based firewalls provide greater flexibility in security design and are also considered easier to administer and maintain especially in large scale network deployments. Palo Alto Networks Next-Generation Firewalls have four main types of Zones namely as shown in the screenshot below: Tap Zone.

What are two benefits offered by a zone based policy firewall on a Cisco router choose two?

What are two benefits offered by a zone-based policy firewall on a Cisco router? (Choose two.) Policies are defined exclusively with ACLs. Policies are applied to unidirectional traffic between zones. Policies provide scalability because they are easy to read and troubleshoot.

How many types of NAT are there in checkpoint?

There are two types of NAT rules for network objects: Rules that SmartConsole. Check Point GUI application used to manage a Check Point environment – configure Security Policies, configure devices, monitor products and events, install updates, and so on.

How does destination NAT work?

Destination NAT is the translation of the destination IP address of a packet entering the Juniper Networks device. Destination NAT is used to redirect traffic destined to a virtual host (identified by the original destination IP address) to the real host (identified by the translated destination IP address).

What is the purpose of a DMZ CCNA?

It analyzes traffic for intrusion attempts and sends reports to management stations. It creates an encrypted and authenticated tunnel for remote hosts to access the internal network. It provides secure connectivity for clients that connect to the internal network through a wireless LAN.

What is NAT in Checkpoint FireWall?

NAT (Network Address Translation) is a feature of the Firewall Software Blade and replaces IPv4 and IPv6 addresses to add more security. NAT protects the identity of a network and does not show internal IP addresses to the Internet.

What is a zone based firewall?

With the zone based firewall, we won’t apply the security policies to the interfaces but to security zones. Interfaces will become members of the different zones. Here’s an example of the topology above with zones: Above you see 3 zones; LAN, WAN and DMZ.

How do I create security zone firewall policies?

To create security zone firewall policies, you must complete the following tasks: Define a match criterion (class map). Associate actions to the match criterion (policy map). Attach the policy map to a zone pair (service policy). The class-map command creates a class map to be used for matching packets to a specified class.

How are firewall policies applied to a network?

(See Figure 2.) These policies are applied, using the network zones defined earlier: Hosts in Internet zone can reach DNS, SMTP, and SSH services on one server in the DMZ. The other server will offer SMTP, HTTP, and HTTPS services. The firewall policy will restrict access to the specific services available on each host.

How does a transparent firewall work between the zones?

A transparent firewall will be applied between the zones, so the inter-zone policies on those two interfaces will only affect traffic between the client and server zones. The VLAN1 and VLAN2 interfaces communicate with other networks through the bridge virtual interface (BVI1).
