[FRS401_IA1262_LAB07_LongNN_SE63194] LAB07: ADVANCED NETWORK ATTACK ANALYSIS --------------------------------------------------------------------------------- A. Data gathering: - Open up the trace and find some of the IP addresses on the local network involved in the communications (look in Statistics-> Conversations) – you can find the local network by looking at the ARP activity (arp):
Image of page 1
- List a few of the MAC addresses of the hosts on the network, and their mapping to the IP addresses (look at arp):
Image of page 2
- Using the tcp.flags.syn==1 && tcp. Flags.ack==0 filter, find all the connections that have been made. Now, using the Follow TCP stream option, determine some of the Web pages that each of the IP addresses on the network has access:

- Using a filter of udp.port==53, determine some of the sites that each of the hosts have accessed: - What is the IP address of the gateway and what is its MAC address (look at the arp filter)?

The gateway is 192.168.0.1

Unformatted text preview: B. NMAP Evidence:-One host does an ARP scan of the local network (use a filter of arp). Which computers are online, and which is the scanning node:-One host does an NMAP scan of a host. Which is the scanning host (you can search with tcp.flags.syn==1 and scroll until you find lots of activity at the same time):-Which is the IP address of the host being scanned:-Which type of NMAP scan has been used (a SYN flood or a Connect scan)? For a SYN flood there is no ACK from the client at the end, whereas for a Connect scan there will be. C. Hydra scan:-Can you locate the first signs of the Hydra attack (identify the packet numbers for the start and end of the Hydra attack)?-Outline a few of the names and passwords that have been tried:-Determine the successful login on FTP (with a user name and password): D. FTP access: E. Cross- correlating against host (FTP traffic): F. Telnet login: G. Emails login: H. Content searching: ~H T~ Ế...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
