Where should a web server be placed in a network?
A web server should be placed in the demilitarized zone (DMZ). The DMZ is a network that contains publicly accessible resources. The DMZ is located between the private network and an untrusted network (such as the internet) and is protected by a firewall.
What servers are placed in DMZ?
Any service provided to users on the public internet should be placed in the DMZ network. External-facing servers, resources and services are usually located there. Some of the most common of these services include web, email, domain name system, File Transfer Protocol and proxy servers.
In which network zone should you place a publicly accessible web Host?
Use a demilitarized zone (DMZ) to protect public hosts on the internet, such as a web server, from attack. The DMZ uses an outer firewall that prevents internet attacks. All publicly-accessible hosts are inside the DMZ.
What is the best location for a network firewall?
Logically, this means that the firewall should be placed between the internet and the network. One of the most basic configurations would be a router that connects to a wide area network (WAN), then a firewall that connects to the router, filtering all traffic before distributing it throughout the network.
What is network zone?
A network zone is a label that describes a network’s purpose within your infrastructure — for example, DMZ, Corporate Intranet, Storage or Production. Network zones: Enable your users to select a network when requesting a new service, without requiring an understanding of the underlying infrastructure.
Should DMZ servers be on the domain?
In the DMZ, generally I’d advise no, they should not be on the DMZ. If they are on the domain and in the DMZ, the issue that you run into is that the web server must have certain connectivity back to at least one DC.
What’s a DMZ zone?
In computer security, a DMZ Network (sometimes referred to as a “demilitarized zone”) functions as a subnetwork containing an organization’s exposed, outward-facing services. It acts as the exposed point to an untrusted networks, commonly the Internet.
How location is important in firewall?
As Figure 22.1a indicates, a firewall is positioned to provide a protective barrier between an external, potentially untrusted source of traffic and an internal network. With that general principle in mind, a security administrator must decide on the location and on the number of firewalls needed.
What is the most appropriate location and strategy for the DMZ and firewall implementation?
In fact, a DMZ should be placed behind a firewall, taking advantage of the protection that a firewall provides. The true benefit of a DMZ comes when you see how one is implemented. A DMZ is nothing more than a segment of your network that is isolated from the rest for the purpose of public use.
What is the difference between DMZ and firewall?
Simply, a DMZ is portion of your network carved off and isolated from the rest of your network. A firewall is the appliance that creates that isolation, by restricting traffic both between the intranet and the DMZ and the DMZ and other networks it’s exposed to. Firewall is a device.

What is DMZ and non DMZ?
Readers | May 29, 2001. When you’re designing a corporate firewall system, you must decide whether to implement a demilitarized zone (DMZ). A DMZ is a barrier between the Internet and a company’s intranet and contains a firewall and proxy server, which can be on separate servers or the same server.
Which direction access Cannot happen using DMZ zone by default?
Which direction access cannot happen using DMZ zone by default? Explanation: Connection from internet is never allowed to directly access internal PCs but is routed through DMZ zone to prevent attacks.
Is DMZ better than port forwarding?
Although they are both used in security, the main difference between the two is how they improve the security. A DMZ is a small part of the network that is openly accessible to the public network or the internet. … Port forwarding is not really essential and you can still use the internet without it.
What are zones in firewall?
A security zone is a portion of a network that has specific security requirements set. Each zone consists of a single interface or a group of interfaces, to which a security policy is applied. These zones are typically separated using a layer 3 device such as a firewall.

How many versions of IP are there?
There are two versions of IP that currently coexist in the global Internet: IP version 4 (IPv4) and IP version 6 (IPv6). IP addresses are made up of binary values and drive the routing of all data over the Internet. IPv4 addresses are 32 bits long, and IPv6 addresses 128 bits long.
What types of protocols are used in VPNS?
Explanation: There are six types of protocols used in VPN. These are Internet Protocol Security or IPSec, Layer 2 Tunnelling Protocol (L2TP), Point – to – Point Tunnelling Protocol (PPTP), Secure Sockets Layer (SSL), OpenVPN and Secure Shell (SSH).
Which one of the following is a safe computing practice?
Use passwords that can’t be easily guessed, and protect your passwords. Minimize storage of sensitive information. Beware of scams. Protect information when using the Internet and email.
Which is faster IPv4 or IPv6?
IPv6 Speed – Web and cloud services provider, Akamai, measured the speed of IPv6 vs. IPv4. They found, “Sites load 5% faster in median and 15% faster for the 95% percentile on IPv6 compared to IPv4.” … Because IPv6 has so many addresses, IPv6 devices don’t require additional configuration.
What is IPv6 vs IPv4?
The main difference between IPv4 and IPv6 is the address size of IP addresses. The IPv4 is a 32-bit address, whereas IPv6 is a 128-bit hexadecimal address. … IPv6 increases the IP address from 32 bits to 128 bits to support larger address demands.
