1.3 Discussion Questions 1. Does a network interface on a sniffer machine require an IP Address? -No, the sniffer doesn't require an IP address, it wants to remain invisible to the other machines in order to intercept messages undetected. 2. In what mode does a sniffer’s network interface operate? -The sniffer operates in promiscuous mode. 3. How do you determine available switches for tcpdump? -The command --help shows the switches. 4. How can you display all of the network interfaces in Linux? -The command ifconfig -a views all the available interfaces on the system. 2.3 Discussion Questions 1. Do FTP usernames and passwords appear in clear text? -They do when intercepted by wireshark on the Linux sniffer. 2. How do you choose the interface to capture on within Wireshark? …show more content…
3. How do you filter for a certain protocol within the Wireshark program? -There is a filter bar at the top which you type into, for example ftp. 4. How do you open the Wireshark program from the terminal in Linux? -Type Wireshark into the root@bt bar. 3.3 Discussion Questions 1. What kind of tool is Network Miner? -Network Miner is a network forensic analysis tool, which can capture images and files. 2. On what operating systems will the Network Miner program run? -It runs on windows operating systems. 3. How do you parse out web pages of visited sites in Network Miner? -You go to the files tab and then open the available information there. 4. What needs to be configured within Network Miner prior to capturing data? -The network adapter need to be configured to the right network

This block performs the flow table (hash table) lookup, updates the per port packet and byte counters and reads the corresponding actions. If the packet header does not match the corresponding hash table entries, then it is considered as a table miss and the packet is dropped. First, the structure of hash table and hashing function are described and then the functionality of exact match is described. The hash table is constructed using 512 deep and 64 bit wide block RAM (BRAM).
This firewall rejects and accepts data by the set of rules. What the rules are called is ACL this gives the text to the packet filter so it know what data can go through or what data can’t go through. The good thing about this type of firewall is that you can personalise so it can work on different protocols. Another good thing about this type of firewall is that it can work at a fast pace for a long time because they are not application-dependant and they don’t have to do extra processing to the data packets.
1. Goal The objective of this lab was to create a Windows 2012 Datacenter Virtual Machine. On this virtual device, we were tasked with installing DHCP, DNS, and Active Directory services. This was very similar to lab 2 in that all of the core services had to be installed on this one device as with our RHEL7 server previously.
Understanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.
The web server is located in the DMZ, and has two interface cards. One is for the traffic from the DMZ firewall, which filters traffic from the internet. This firewall is the first line of defense against malicious users. The web server sits behind this firewall, in the DMZ. Then before packets can travel to the next Ethernet card, an additional firewall filters out any stragglers.
When asked what a network is, I usually think about the internet or my phone’s network. It had never occurred to me to go further in depth on the subject. In order to fully understand what a network is we must look into what all networks have in common. All networks whether they are a broadcast, a computer, or a business network (the list goes on) all share common traits. There exists a hierarchy within each network and the more connections one has, the better.
IP address scanning is used because most worms rely on IP addresses to identify other hosts (Rajesh, Reddy, & Reddy, 2015). The forensic analysis software will use these methods of detection to determine the existence of a worm and the initial
Software routines will handle traffic that is coming in from different sources and that will choose where it will end up. Towards the end it will work out where it need to go and which devices will take the data. Also devices and software such as for interface card for the device driver. This is allowing the data to handle incoming packets from various locations and it select the last place it travels to. Error handling and diagnostics is when a device is allowed to access a network layer locally.
It can perform protocol analysis, content searching/matching and can be used to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, OS fingerprinting attempts, and much more. Snort uses a flexible rules language to describe traffic that it should collect or pass, as well as a detection engine that utilizes a modular plug-in architecture. Snort has a real-time alerting capability as well, with alerts being sent to syslog, a separate “alert” file or even Windows computer
Human traffickers use smart Phones, GPS, videos cameras, social media websites, and many more technological devices, and these devices are easier to detect them. For example, a law enforcement group in 2003 has launched an operation pin that creates websites that contain child abuse or pornography contains. These websites were a trap to find Internet users who are seeking access to such contains. The minute that the user enters the website, his data is copied and recorded; hence, getting his or her criminal records. Furthermore, the justice systems, in some countries, were able to authorize instilling technological surveillance on suspected traffickers.
The security issues accompanying the information mining operations are twofold. On one hand, if individual data can be straightforwardly seen in the information and information rupture happens, protection of the first information proprietor (i.e. the information supplier) will be bargained. Then again, outfitting with the numerous effective information mining procedures, the information excavator can find out different of mining client information, is something that the little girl does not need others to know.
