The first Virtual Machine should be installed and have the BIND (DNS) server installed on it. While you do not own any address space/ name space your name server should manage the following domains:
The name server should answer queries for this domain. In addition to the saffioti.org.au zone, a zone should be set up for the reverse zone – the reverse zone would be whatever the address range is of your virtual machine. You should do some research on how Bind handles reverse zones.

INFA 620Laboratory 4: Configuring a Firewall
In this exercise you will be working with firewalld (see https://www.linode.com/docs/security/firewalls/introduction-to-firewalld-on-centos), a front-end to controlling Iptables. Iptables is a flexible firewall utility built for Linux operating systems (see https://www.howtogeek.com/177621/the-beginners-guide-to-iptables-the-linux-firewall/). It is too low level, however, and, as such, hard to use and configure the rules for filtering traffic. firewalld provides higher-level command line and graphical interfaces over Iptables to ease the pain of configuring the firewall features provided by Linux. For this lab exercise, we will only be using only the high-level command line interface. firewalld provides a dynamically managed firewall with support for network/firewall “zones” to assign a level of trust to a network and its associated connections, interfaces or sources. It has support for IPv4 and IPv6. There is a separation of the runtime and permanent configuration options.
For this lab exercise, we will be using two machines, one machine will behave like an Enterprise and the other machine will behave like machines outside an enterprise. We will call this machine as External, external to the enterprise. The firewall, as part of the enterprise will control traffic both coming into the enterprise and going out of the enterprise (to External).
NIXENT01 (Enterprise) is a CentOS 7 machine.CentOS is a Linux distribution that attempts to provide a free, enterprise-class, community-supported computing platform. Firewalld will be running on this host.
NIXEXT01 (External) is Kali Linux. Kali Linux is a Debian-based Linux distribution aimed at advanced Penetration Testing and Security Auditing. Kali contains several hundred tools which are geared towards various information security tasks, such as Penetration Testing, Security research, Computer Forensics and Reverse Engineering. You have already used this machine for Lab2 and Lab 3 in analyzing packets using Wireshark. (Wireshark is available as part of Kali distribution.)
Although there are only two machines, we are going to pretend that the Enterprise has three machines (three IP addresses) and each machine has certain services running on those machines, as follows:
NIXENT01 (Enterprise)
Service
Associated IP Address
domain, telnet
192.168.10.10
http, https
192.168.10.20
ftp, imap2, imaps, pop3, pop3s, urd
192.168.10.30
Similarly, we are going to emulate three machines on the External machine with three IP addresses, each running only certain services as follows:
NIXEXT01 (External)
Service
Associated IP Address
domain, telnet
192.168.10.210
http, https
192.168.10.220

Installation And Configuration Of DNS, Web And FTP Servers On Virtual Machines Using Ubuntu And CentOS.docx
1. Installation And Configuration Of DNS, Web And FTP Servers
On Virtual Machines Using Ubuntu And CentOS
Part 1: Virtual Machine One – DNS & SSH Server
The first Virtual Machine should be installed and have the BIND (DNS)
server installed on it. While you do not own any address space/ name
space your name server should manage the following domains:
The name server should answer queries for this domain. In addition to
the saffioti.org.au zone, a zone should be set up for the reverse zone
– the reverse zone would be whatever the address range is of your
virtual machine. You should do some research on how Bind handles
reverse zones.

Part 2: Virtual Machine Two
The second Virtual Machine is to have the LAMP software package
installed. LAMP is a standard bundle in the Ubuntu Server platform.
Once complete set up this Virtual Machine to host a website using the
Apache Web Server.
The Virtual Machine should have a statically assigned address which
matches that specified in the A record for host www. Test your Apache
Server Virtual Machine by using a web browser on another host and
trying to browse the website www.saffioti.org.au.
2. Finally harden this host so that only services being used can be
accessed by other machines. You will need to use IPTables.
Part 3: Remote File Access
Once you have set up the web server (in part 2) and tested it, install
any FTP server. The FTP server would allow users to upload/ download
files to the web server. Configure the server appropriately and then
test from another host. You will need to make changes to your firewall
configuration. In addition to this add a CNAME for ftp on the name
server pointing to server2.
Document the entire process and challenges you experienced.
Part 4: Making DNS Robust
You are to also install bind on Virtual Machine Two and make it a
secondary for the above domain. You can install this service from a
package or configure from source.
Part 5: Simple Web Services
In Virtual Machine Two you set up a web server for the DNS
namesaffioti.org.au.The server is implemented using the HTTP
protocol listening on port 80. Your challenge is to make the same site
accessible using the HTTPS protocol. To do this set up SSL with a self
signed certificate for the site.
In this assignment, two virtual machine running Ubuntu and CentOS
were installed and configured on a VMware Workstation Player. The
first machine was installed with a BIND, to provide DNS & SSH services,
3. while the second one was installed with a Web Server. The name
server on virtual machine 1 was configured to manage the domain
saffioti.org.au. A zone was also set up for the reverse zone and
hardened by use of firewall rules, which allowed access to the
services. The virtual machine running Ubuntu OS was the web server,
where LAMP was installed. The Apache Web Server in the LAMP
software was used to host a website. Additionally, an FTP server was
configured on the same virtual machine.
Part 1: Virtual Machine One – DNS & SSH Server
This virtual machine was installed with CentOs, and a BIND (DNS)
installed and configured on it. The name server was configured to
manage the domain;
org.au
Step 1: Install Bind
sudo yum install bind bind-utils
Step 2: Configure DNS
The namde.conf file was edited as shown below.
nano -w /etc/named.conf
Step 3: Configure bind zone
nano -w /var/named/saffioti.org.au.zone
Restart the Service, then enable it to start automatically at boot time;
4. the following commands were used;
service named restart
chkconfig named on
Part 2: Virtual Machine Two: Server2
Ubuntu Operating system was installed on this virtual machine, and
used as a web server. To enable it server as a web server, LAMP was
installed.
By definition LAMP is a stack of open source software tools, that are
normally installed together to facilitate hosting of dynamic websites
and web applications. LAMP translates to Linux, Apache, MySQL, PHP.
The three software are installed on Linux along each other to facilitate
web hosting. In this exercise, the software were installed in a series of
steps as outlined below.
step 1: Install Apache
To install Apache, the following commands were used;
sudo apt-get update: this command is used to update the list of
packages and their version. The command only gets and updates
information about the packages but does not install the updates.
sudo apt-get install apache2: the command installs apache web
server.
To confirm that the Apache Web server was successfully installed, the
default apache page was accessed from a web browser;
5. Step 2: Install MySQL
MySQL database was installed using the command;
sudo apt install mysql-server
Step 3. Install PHP
For PhP to work, a number of packages had to be installed as outlined
below.
sudo apt install php-pear php-fpm php-dev php-zip php-curl php-
xmlrpc php-gd php-mysql php-mbstring php-xml libapache2-mod-php
Hardening the Web Server
To harden the web server, which makes it more secure, by only
allowing access to the web hosting services, the firewall was
configured using IPTables. The process is as outline below.
Step 1: Install the Persistent Firewall Service
For the firewall service to run on the machine, it was necessary to
install the iptables-persistent package. The packages allows the rules
set to be persisted and be applied automatically at boot time. The
following command was used to install the package
sudo apt-get install iptables-persistent
Step 2: edit the iptables for IPv4
sudo nano /etc/iptables/rules.v4
6. The same was done for IPTables for IPv6 with the command;
sudo nano /etc/iptables/rules.v6
To test for errors in the modified files, the following two commands
were used;
sudo iptables-restore -t /etc/iptables/rules.v4
sudo ip6tables-restore -t /etc/iptables/rules.v6
No error was reported, meaning the iptables files were okay. The next
command was used to activate the rules.

Part 2: Virtual Machine Two - LAMP Server
Difficulties Encountered
Major difficulties were encountered trying to harden the web server.
The iptables-persistent service was not running and attempts to start
it failed with the error;
"Failed to start iptables-persistent.service: Unit iptables-
persistent.service not found"
After an hour of headache and Googling, I finally found a command to
start the service.
sudo service netfilter-persistent start
7. I realized that the failure to start was a problem with some versions of
Ubuntu; the above configurations seemed not to work and I had to do
the following steps to harden the server with a firewall using IPTables.
Step1; resetting the firewall
sudo service netfilter-persistent flush
After flushing, I verified that the rules were removed.
Create Protocols
The next step was to crete specific chain of protocols that the web
server will accept; UDP, TCP and ICMP
sudo iptables -N UDP
sudo iptables -N TCP
sudo iptables -N ICMP
Since SSH traffic uses TCP protocol, I had to add an exception for SSH
on the firewall. SSH traffic uses port 22. The following command was
used to create the exception.
sudo iptables -A TCP -p tcp --dport 22 -j ACCEPT
General Purpose Accept/Deny Rules
To facilitate filtering of traffic, some general purpose rules were
created to accept of drop packets. For a start traffic for an already
8. established connection was accepted; this was implemented by the
command.
sudo iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED
-j ACCEPT
The firewall rule for filtering makes use of conntrack package, which
enables internal tracking, allowing the iptables have the context to
facilitate evaluation of packets.
Allow Loopback traffic
To allow traffic from the loopback interface, the following command
was executed
Deny all invalid Packets
Packets that are invalid such as those that address a non-existing port
has to be denied. This was implemented using the command.
sudo iptables -A INPUT -m conntrack --ctstate INVALID -j DROP
Jump Rule for Protocol-Specific Chain
To allow traffic reach the desired protocols, some jump rules were
created. The rules will filter the traffic and only allow the genuine and
valid traffic. For example TCP traffic will be filtered to only allow SYN
packets, since SYN is the only valid traffic for TCP type connection.
The following commands were executed to allow the rules to be
create;
9. sudo iptables -A INPUT -p udp -m conntrack --ctstate NEW -j UDP
sudo iptables -A INPUT -p tcp --syn -m conntrack --ctstate NEW -j TCP
sudo iptables -A INPUT -p icmp -m conntrack --ctstate NEW -j ICMP
Finally, a rule was created to reject all other traffic hitting the server.
The commands below was used to create the rules;
sudo iptables -A INPUT -p udp -j REJECT --reject-with icmp-port-
unreachable
sudo iptables -A INPUT -p tcp -j REJECT --reject-with tcp-reset
sudo iptables -A INPUT -j REJECT --reject-with icmp-proto-unreachable
sudo iptables -P INPUT DROP
sudo iptables -P FORWARD DROP
sudo ip6tables -P INPUT DROP
sudo ip6tables -P FORWARD DROP
sudo ip6tables -P OUTPUT DROP
sudo service iptables-persistent save
The final state of the iptables is as shown below;
Part 3: Remote File Access
This part will install and configure FTP service on Ubuntu [server2]
10. Step 1 — Install vsftpd
The following command was used to install vsftpd sudo apt-get install
vsftpd
Step 2: Configure firewall rules to allow FTP service
This configuration will open port 20 and port 21 which are used by the
FTP service; for this server the firewall rules were set using iptables.
For that reason we need to add a rule in the iptables to allow FTP
traffic. The following commands were used; iptables -A INPUT -p tcp -
m tcp --dport 21 -j ACCEPT
The iptables after adding port 21 and 22.
Step 3 — Prepare User Directory
First add a test user; sudo adduser saffioti
Then create a directory for the user and assign rights;
sudo mkdir /home/ saffioti /ftp
sudo chown nobody:nogroup /home/ saffioti /ftp
sudo chmod a-w /home/ saffioti /ftp
Next we create directory for uploading files into and change the rights;
sudo mkdir /home/saffioti/ftp/files sudo chown saffioti:saffioti
/home/saffioti/ftp/files
Step 4 — Configuring FTP Access
11. To configure access to FTP we edit the file; sudo nano /etc/vsftpd.conf
Step 5 — Test FTP Access
Testing with anonymous connection
Part 4: Making DNS Robust
Installing a bind on server2, to make it the secondary DNS server.
Installing BIND: apt-get install bind9
Configurations for BIND nano /etc/bind/named.conf.local
Then configure the zones file named; saffioti.org.au
Define a reverse DNS lookup nano /etc/bind/zones/rev.3.2.1.in-
addr.arpa
Testing the DNS confirmed it was up and running
Part 5: Simple Web Services
Step 1: Generate the self signed certificate
Then we sign the certificates followed by modification of Apache's
default ssl configuration file
Finally we edit the file /etc/apache2/sites-available/default-ssl.conf
