- Your network is protected from threats in the outside world by a firewall.Be sure to stick to these guidelines when operating the packet filtering program.arrow_forwardYour 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?arrow_forwardYou have a client that has two servers that must transfer sensitive information between them across the network. The transfers of data must be encrypted so the information cannot be used if someone captures it as it traverses the network. What technology can you use? a. firewall b. BitLocker c. Kerberos d. IPsecarrow_forward
- What is the IP address of the firewall on the local LAN?arrow_forwardCreate a firewall rule for sales to block a specific port. Which port are you blocking? Which protocol uses that port? Provide a screenshot of your workarrow_forwardWhich of the following is the most crucial function performed by a firewall?Presently, I am working on a packet-filtering program. Please tell me where I may get a set of guidelines to follow.arrow_forward
- A client complains that since the new firewall was installed, he or she has been unable to transmit webmail. What firewall ports should be investigated?arrow_forwardJane Smith is responsible for security at the ABC Company. She has a moderate budget with which to purchase security solutions. To date, she has installed a router-based firewall between the network and the outside world. She also has a commercial virus scanner on every machine on the network. What other actions might you recommend to her? Would you recommend a different firewall? Why or why not?arrow_forwardWhich of the following is NOT a purpose of a firewall?I've started developing a software to filter packets. If so, could you perhaps outline some rules for me to adhere to?arrow_forward
- Can you recommend any other kinds of firewalls except router-based ones?arrow_forwardAs a network administrator, you are already aware of the possible option of using a default trust relationship between a network device and another by a hacker to access an entire network. Which of the following security measures will you use to prevent a possible DoS attack that can be induced by sending high volumes of router advertisement messages? 1. DHCP Snooping 2. CoPP 3. RA guard 4. DAIarrow_forwardYour network devices receive IP addresses using DHCP. Your network monitoring gear detects a significant amount of traffic inside the engineering department from many of the hosts there and one particular device. A little analysis if the traffic reveals that the target device is an unsanctioned server. What 5 policies should be in place which should prevent rogue devices on the network? What 5 security risks might exist on the detected server which are beyond your capability to fix?arrow_forward
