Advance Computer Security (ACS) Individual Assignment – 40% Due Date
For this assignment, student should have configure the following environment. 01. Microsoft windows 7 or later OS as host OS 02. Configure Virtual environment on Host OS 03. Create a Guest OS on virtual environment. Guest OS Must be a Linux flavour 04. Install Apache on Guest OS 05. Host a simple web page at your web server. The page name MUST be index.htm 06. Install packet sniper at Host OS
CentOS 7 was installed in a virtual environment, and apache was installed in CentOS 7.
Apache was added to the services
Default apache web page
My sample web page
Wireshark was used as the packet capturing software in the host machine which is a windows 7 host.
Question 01While running packet capture software, ping the web server and collect packets. Inspect the packets. Identify the following fields. IPv4 Header information and protocol information. You must describe the findings.
Answer Figure below shows data of an ICMP packet capture by the software “wireshark”. The first box shows the internet protocol version as IPv4
And the second box show the protocol used as ICMP (1)
Question 02While running the packet capture, access the web page and collect packets pertaining ONLY to the transaction you made. Identify the following. Three way handshake. You must describe the findings.
Answer The below figure shows the TCP 3 way handshake of the web server and the host machine.
1. Fist the host machine with IP address 192.168.1.7 sends a [SYN] to the webserver which is 192.168.1.6.
2. The webserver sends back a [ACK] as an acknowledgment of receiving the [SYN] from the host machine.
3. The webserver also sends a new [SYN] to the host.4. The host the sends a [ACK] to acknowledge the [SYN] sent by the webserver.
At this point the 3 way hand shake is completed
Question 03While running the packet capture, access the following URL
URL: http://your_web_server_IP/test
Collect packets pertaining ONLY to the transaction you made. Identify the following.
Error code, server information and version information
