- Johnathan is the network engineer of an organization that restricts the use of certain webpages. As he does not have any pending work, he decides to take a break and watch a movie online until a task is assigned to him. Analyze which of the following actions is best suited for him in this situation so that the IP address of the organization is not compromised. a. Use a network-based firewall for this purpose b. Use IDS to bypass security protocols c. Use proxy servers to mask Internet activities d. Use a packet-filtering firewall for this purposeWrite down two firewall rules on the router using the format below (network interface, protocol, flag, source IP or CIDR, source port, destination IP or CIDR, destination port, action) Rule1: block all of the incoming pings sent to the 172.20.241.0/24 subnet; Rules2: block all of the outgoing pings to any computers outside of the 172.20.241.0/24 subnet. What network attacks can the above firewall rules potentially protect against? Please identify one example of these attacks. Explain how this attack can be conducted and how this attack can be blocked using the rules above. For the file rules in Q4.1, is it for stateful inspection or non-stateful inspection (2pts)? Can a non-stateful inspection firewall detect TCP SYN Flood attack? Why or Why not?Tobias wants to know more about software-defined networking, which separates the data plane from the control plane.

Ethernet switch Alessio is evaluating the security of the virtual environment being used at your organization. Which of the following is a concern that Alessio should have? a. All hypervisors have the necessary security controls to keep out attackers. b. A VM can be used to test for potential malware. c. A snapshot of a VM's state can be saved for later use. d. Traditional security tools do not always adapt well to multiple VMs.
- Your firm has entered into a data-sharing arrangement with another firm.Both firms' administrations have agreed to use FTP to transfer data over their networks.Data will be transmitted between already-established servers on both ends of the network.You've been tasked with devising a firewall-specific method for allowing this new connection.What are your plans for the future? Which one do you think is the best, and why?This a small corporate network installed in a building. It has three switches connected to the border router with built-in firewall capability to prevent intrusions from the Internet. Disregarding the connection between the firewall router and the Internet: a. How many LANs are there? b. How many subnetworks are there? c. If PC1 sends a message to the email server, is this inter-networking? d. If PC1 sends a message to the file server, is this inter-networking? e.

- The network address for an organisation’s network is 54.33.112.0/23. Provide the subset of the filter table for a stateless firewall that includes the following rules: - Allows all internal users to establish HTTP with any external hosts but blocks FTP. - Allows external users to browse the company web page at 54.33.112.4 - Allow incoming TELNET requests to all organisation hosts apart from those in subnet 54.33.112.0/24 THIS IS ALL INFORMATION PROVIDED PLEASE My last question about has not been responded correctly, please you must provide the subset of the filter table for a stateless firewall that includes the following rules.Which of the following is a concern when considering the use of a demilitarized zone (DMZ) firewall solution to access high value data on an internal network? A. Expense B. Poorly constructed firewall rules C. Encryption D. Virtual private network (VPN) server vulnerabilitiesCOM Assume a web browser at a client host (212.13.14.16) wants to send a message to a web server (156.10.10.2) but a firewall at the client's gateway (212.13.14.1) is configured to block all outgoing packets to 156.10.10.2. The client does have access to a VPN application (similar to the one used in the labs) and can use it to connect to a VPN server (130.16.10.2). Describe how the client should set up a tunnel to bypass the firewall so that the web browser can send a message to the web server (156.10.10.2). You must trace the pathway of the message originating at the web browser on the client host and headed to the VPN server explaining how it traverses through different layers (application, transport, network etc.) in the client host and finally reaches the VPN server application. You must also trace the relevant hops (i.e., the IP addresses) the packet navigates through along the way. You need not trace the reply message and you also don't need to focus on the encryption details.…
- A virtual private network (VPN) is the best option for protecting the perimeter of a network. Can they secure portable electronics as well? A longer piece than a couple of lines Can you explain what an ACL is and how it works? A firewall is defined as. If possible, please use at least 250 words to explain the distinction. To what do they both contribute?Your firewall is configured to allow traffic to flow in and out of your network. GIVEN THE SETTING BELOW FOR THE FIREWALL RULE: Rule Name: DNS Rule Source IP: DNS / Source Port: 53 Destination IP: Any / Destination Port: * Protocol: Any What traffic flows through the firewall? IF SOME ACTIVE ATTACKS ARE ADDED FROM THE LIST. Is the rule sufficient to allow traffic to flow for a typical network? Why or why not? Do any of the active attacks now work against machines behind the firewall?A virtual private network (VPN) is the obvious option to go with when it comes to protecting the network perimeter. Do they also provide protection for mobile devices? A significant number of lines What exactly is an access control list, sometimes known as an ACL? What exactly is a firewall, then? In no less than 250 words, explain the key differences between the two. What are the things that they share in common?
