- For the network shown in below which has an address 192.168.45.2:Find and apply a valid IP range address for each component within the network by using variable length subnetting mask of each host for the * .LAN/WAN environments 30 hosts Network B 20 hosts Network A= Your first name Network C FO/O FO/O Network B=Your middle name Network C= Your last name Lab_D Lab E 2 hosts Network F Network D=Your first name * Network E=Your middle name * Network F=Your last name * Lab_A Lab_B 2 hosts Network G= Same name FO/O 6 hosts Network D FO/O 14 hosts Network A Network H Network H= Same name 2 hosts Network GAssume that there is a system call connect). This system call takes an IP address as an argument and then creates a TCP connection with that IP address. For example, connect(10.10.10.10) will create a TCP connection with the machine that has the IP address 10.10.10.10. Now, imagine that for the ptrace sandbox, the connect() system call is blocked for a known bad IP address 20.20.20.20. However, the attacker wants to connect to this blocked IP address (the attacker wants a TCP connection to 20.20.20.20, which is not allowed in the policy). It is also given that the connect() system call is allowed for the IP address 1.1.1.1. What can the attacker do to bypass this restriction and trick the ptrace sandbox (and the Operating System) Into running the connect() system call with the argument 20.20.20.207Given the Class C network of 204.15.5.0/24, subnet the network in order to create the network shown below with the host requirements. netA: 14 hosts netD: 7 hosts netC: 2 hosts netB: 28 hosts netE: 28 hosts
- Write an access list that denies IP traffic from host 152.5.35.83, permits IP traffic from host 104.2.64.34 and all hosts on networks 185.25.0.0/16, and denies all other IP traffic. Invoke your access list inbound on interface S0/1.Given the Class C network of 202.20.15.0/24, subnet the network in order to create the network in the figure below, with the host requirements shownIn this programming assignment, you will implement a decentralized peer-to-peer network architec-ture (P2P), including the basic implementation of the BitTorrent protocol (BTP). General P2P architec-tures can be classified into centralized and decentralized, In P2P centralized architectures, new peers senda request to the Traker (normally done via HTTP) requesting a list containing all the IP addresses ofthe peers that are already connected to the P2P network sharing the same file. The tracker then, replieswith a response containing such list. In P2P decentralized architecture, each peer is also a Traker, and itcan share only limited resources because it only sees the partial network. On the other hand, P2P decen-tralized networks avoid single point of failure since they do not depend of centralized trackers. Examplesof P2P applications that are/were implementing centralizing architectures are Nasper, the Berkeley OpenNetwork Infrastructure (BOINC) and some versions of BitTorrent.…
- Consider a network 192.168.0.0/24. Specify the 04 subnetworks of the aforementioned network with complete details of each network.7.1 In IEEE 802.11, open system authentication simply consists of two communications. An authentication is requested by the client, which contains the station ID (typically the MAC address). This is followed by an authentication response from the AP/router containing a success or failure message. An example of when a failure may occur is if the client's MAC address is explicitly excluded in the AP/router configuration. a. What are the benefits of this authentication scheme? b. What are the security vulnerabilities of this authentication scheme?For example, let say that your Network 1 needs 30 hosts and you are in a class C network, you would start with 192.168.0.1 till 192.168.0.32 because the closest you can get to 30 that is more is 32 (2exp5) so my begin address would be 192.168.0.1, end address would be 192.168.0.32 (not 192.168.0.30 because we only need 30 hosts) and subnet mask would be 255.255.255.224. The next range will start at 192.168.0.33!!! Use the example to answer: We are going to use the private range for a class A network. What is its standard subnet mask? A) Network 1 needs 250 hosts B) Network 2 needs 230 hosts
- Suppose you have a class C Network 200.94.115.0. Your task is to design a subnet scheme so that we can create 28 Network segments (subnets) within this Network. Each subnet should support hosts as given below. 2 Network Segment support 30 Hosts 4 Network Segment support 14 Hosts 8 Network Segment support 6 Hosts 14 Network Segment support 2 Hosts3.3 Contrast TCP and UDP. As a software architect, provide two applications where you would choose to use TCP instead of UDP.Given the following topology of a network, the router Node 3 connects the two subnets together: Nodes 1 and 2 are 'inside' of the subnet neta, Nodes 4 and 5 are 'outside' of neta and Node 3 with a firewall is the gateway of neta. The two networks have the prefix 192.168 as the first two octets in their IP addresses, e.g, Node 1 has IP address 192.168.1.11. eth1: 1.11 eth1: 2.21 1 2 eth1: 1.12 neta eth 1: 1.1 3 eth2: 2.1 netb 4 5 eth1: 2.22 (i) Suppose in the firewall on Node 3 the default policy is ACCEPT. Write packet filtering rules for the following goal. Suppose Node 5 hosts a web server supporting both HTTP and HTTPs. Set rules in Node 3 that prevents Node 2 from browsing any web pages at Node 5. Now change in Node3 the default policy as DROP and write packet filtering rules for the following goal. (ii) Allow all nodes in the subnet neta to browsing HTTP pages hosted at Node 5. (iii) Allow hosts in netb to SSH into Nodel.
