It’s not utilized in the firewall implementation, but it’s a rule… It’s not utilized in the firewall implementation, but it’s a rule number that you may use to monitor a specific rule. Setup-firewall.py does not verify any value for this field. Match traffic and do not give rules precedence in this area, please.   o Block or Allow as an action Traffic that meets the remaining criteria of this rule will be blocked by block rules. As a result, the firewall’s Let rules will override Block rules in order to allow specified traffic through (see below for an example). A string is the entry (Block,Allow). This is the MAC address of the source and the destination. MAC Addresses may be used to identify a specific host. Use to match a certain piece of hardware in the real world. SDN-topology.py defines the MAC address of each host in the network. Network Address in the form of xxx.XXXXXXXXXXX in CIDR notation for the source and destination. A single IP Address (using its IP address and a subnet mask of /32) or a specific Subnet may be matched using this method. An entry might look like this: 10.0.0.1/32. Make certain that the IP Address shown is the Network Address if you’re not using /32 (individual host) as your CIDR mask. Cidr notation is explained in this primer.In an IP Address, the network and host addresses are encoded in 32 bits. Bits are split into four 8-bit chunks for a total of 32. The subnet mask /24 specifies the maximum number of bits in an IP Address that may be used to identify a specific network. 24 bits are used to identify the network and 8 are used to identify a specific host. A network address is defined by the first 24 bits (the 192.168.10), whereas a host address is defined by the last 24 bits (0). (255 hosts). For a /24, the IP must reflect the first 24 bits of the network address. The complete 32 bits of the /32 address are a network address and indicate one host. For each host, an IP address is specified in sdn-topology-py.Protocol is defined by the IANA as an integer IP protocol number (0-254). An IP example is ICMP. Protocol 1 is TCP, Protocol 6 is IP, and so on. An integer is required. Source/Destination Port = IANA Application Port Number if Protocol is TCP or UDP. TCP Port 80, for example, is often used for online traffic. If you want to verify the regulations for this project, the following website is the place to go: https://en.wikipedia.org/wiki/List of TCP and UDP port numbersTo further complicate things, don’t utilize ICMP port numbers to distinguish between various parts of the protocol. You may use this to keep track of the regulations.     In your current position, you work for GT-SDN Corporation, a multinational firm with locations in China, India, and the United Kingdom, which serves as the company’s data center. The following objectives must be achieved by the firewall you build:   • Task 1: You have two active DNS servers on the headquarters network.the older DNS-over-TLS protocol and the more recent UDP protocol)standard). The public DNS service provided by hq1 is available to everyone, whereas the private DNS service provided by hq2 is only accessible to the five business networks (i.e., the US, China, India, UK, and Headquarters network). In order to accomplish such policies, write out a set of firewall rules. (UDP Port 53 and UDP Port 853 are the only ports you should use)   Host hq3 serves as a virtual private network (VPN) server on the headquarters network and links to each of the other sites (hosts us, uk, in, and cn3).VPN server that uses OpenVPN (standard ports – both TCP and UDP Ports 1194). configure the firewall so that only the four remote hosts (us3, uk3, in3, and cn3) may connect to the hq3 OpenVPN server. Other hosts should not be able to connect to the OpenVPN server on hq3 for any reason.   Task 3: Make the Headquarters network accessible through ICMP ping to all other networks across the globe (including from the us, uk, in, and cn networks). Due to firewall implementation constraints, the hq network would be able to ping the us, uk, in, and cn networks from the rest of the globe. Why? What modifications to the implementation requirements may be made so that this is possible?   • Task 4: Ransomware may infiltrate a business network through a remote desktop connection, either via an unsafe version of a browser or by exploiting a vulnerability in the operating system.Microsoft Remote Desktop Protocol (MDP) or Virtual Network Computing (VNC) protocols are both acceptable options for a remote desktop server. A set of rules should be created to prohibit Internet access to the five business networks’ remote desktop servers. us, and the rest of the world to participate 20 remote desktop server on the headquarters network using in and cn When using VNC or Remote Desktop, use TCP Ports 3389 and 5900.   • Task 5: A micro webservice on TCP and UDP Port 8500 handles financial data on hosts us3 and us4. It’s recommended that this service be restricted to hosts uk2, uk3, uk4, uk5, and uk6, as well as in4, in5, us5, and hq5. Use the lowest subnet mask that handles the given hosts in CIDR notation, and keep track of their IP addresses.)   In order to prevent the GRE IP Protocol from entering any of the five corporate networks, complete Task 6. (i.e., the US, China, India, UK, and Headquarters network). Encapsulation protocol GRE is utilized in PPTP-based VPN connections. PPTP-based VPN connections do not use any of the ports you’ve blocked; only the IP protocol does.   #!/usr/bin/pythonPOX-enabled SDN firewall project for CS 6250 Fall 2020# habit-v23-building In order to evaluate your work, this file specifies the topology that will be utilized.

Beginning at zero, work your way up to thirty-six in steps of six. Establish the database and give it the name “Inventory Usage Ageing.” Select just the PRODCODE, DEPOT, TOTALCOST, and MONTHS fields by clicking the Fields to Include button. The outcome of the stratification should be printed out as a three-dimensional chart, and then the chart should be saved as a pdf file. Take a snapshot of the things that have been in inventory for more than 36 months. How many product lines have an use period that is longer than 36 months?3. Determine how accurate the system is at automatically reordering inventory. You may pick the things you want to look at by using the @BETWEEN function to find those where the quantity is between MIN and MAX. There are three inputs required for the @Between function. The first factor is the area that is being evaluated. The second value represents a low limit for that field, whereas the third value represents a high limit for that field. @Between chooses the things that fall somewhere in the middle of the two limitations. The notation @Between followed by is quite often seen in usage. NOT to identify objects that fall beyond the parameters that have been established.4. Locate products for which an up-to-date selling price has not been recorded. This is known as the CURSELLPRI. Instead of doing an extraction, you should use Criteria.5. Make a column that shows if there has been an increase or drop in the selling prices. Calculate the percentage difference between PREVSELPRI and CURSELPRI. This is the basic calculation. Please refer to it as the PRICE MOV field. However, if PREVESELPRICE is equal to zero, the percentage should be shown as 100. Make a stratification result using this field’s increment of 10, then save it.6. Extract any PRICE MOV values that have a significant variation, such as those that have grown or reduced by a factor of 50 percent. You may determine increases or decreases of more than +50 percent or -50 percent by using the @Abs function. However, exclude the instances in which PREVSELPRI=0.7. Make a new field that can determine the percentage of the profit margin; this is essentially the difference between the CURSELPRI and the AV COST fields. However, if CURSELPRI is equal to zero, the profit margin percentage should be shown as 0Image transcription textGiven the following recursive function:f(0) =1 f(n)=2f(n-1)+2″ n>0Answer 1-4 1.
