Project A: OS Systems and Networking
Project A consist of installing and configuring different type of Operating Systems, configuring a Network, use a network tool, create security baselines and develop a Professional written report which documents you work
Scenario
You have been hired by an I.T company as an I.T subject matter expert. Management has a client who wants to upgrade their I.T system, but the client has a limited budget and no more physical space to install new equipment. You suggest implementing virtual machines instead of more hardware to help reduce the cost and to meet the client's operational needs. Part of the upgrade includes installing a Firewall, a PC for the CEO, a Webserver, DNS Server, and some Linux machines for monitoring and conducting cybersecurity related tasks. Once the new network is installed, you will document configurations and create a security baseline and a security baseline by scanning open ports
For Project A consist of a 3 legged DMZ that is being deployed which means that for the Trusted Network which consist of the Trusted Kali Linux machine and the CEO PC will be on the same I.P Address(192.168.0.0/24), The DNS Server, Webserver and the Kali DMZ will be on the same I.P Address(10.200.0.8/29) and the Kali-Untrusted will have its own I.P Address as well(172.30.0.0/24). Before starting this project, I used a Virtual Machine called Virtual Box which consist of running different type of virtual machines (Think of running Windows 10 OS as your Host Machine and running Windows 7 OS as your Guest Machine). The OS that I used was Kali Linux which is a specially designed OS for network analysts, Penetration testers, or in simple words, it is for those who work under the umbrella of cybersecurity and analysis. Each Kali Linux machine has its own flavor of OS; Both the CEO PC and DNS server was running on the CentOS 6.4 version of Kali Linux while the Webserver was running on Ubuntu 8.04 version of Kali Linux
CEO-PC
IP Address: 192.168.0.16
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
WebServer
IP Address: 10.200.0.12
Subnet Mask: 255.255.255.248
Default Gateway: 10.200.0.9
DNS-Server
IP Address: 10.200.0.11
Subnet Mask: 255.255.255.254
Default Gateway: 10.200.0.9
Once Adding the CEO-PC, DNSServer and WebServer to the Virtual Machine, First I noticed that the CEO-PC had the wrong IP Address which I ran a ifconfig command as well as running and ping command between the CEO-PC, DNSServer and Webserver which I had to change manually to give each Virtual Machine its own IP Address statically using DHCP (Dynamic Host Configuration Protocol).From there, I doubled checked and got a connection from all 3 Virtual machines and logged on to Seclab.net
After going to Seclab.net, I had to run a FTP (File Transfer Protocol) command to download Social-Media-Security-Policy by using FTP seclab.net. Once it got a connection, I had to sign into to FTP and once the login was complete, I downloaded the Social-Media-Security-Policy
I also successfully added a new user in the Webserver using the adduser and passwd command in command prompt To sign in as the new user, I used the su username01
