What is the system designed to prevent unauthorized access to or from a private network called as? Correct Answer Firewall

The correct answer is Firewall.

Key Points

  • A firewall
    • It is a system designed to prevent unauthorized access to or from a private network. Hence, Option 4 is correct.
    • You can implement a firewall in either hardware or software form, or a combination of both.
    • Firewalls prevent unauthorized Internet users from accessing private networks connected to the internet, especially intranets.
    • All messages entering or leaving the intranet (the local network to which you are connected) must pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
    • In protecting private information, a firewall is considered the first line of defense; it cannot, however, be considered the only such line.
    • Firewalls are generally designed to protect network traffic and connections, and therefore do not attempt to authenticate individual users when determining who can access a particular computer or network.
    • An inter-network connection device that restricts data communication traffic between two connected networks.
    • A firewall may be either an application installed on a general-purpose computer or a dedicated platform (appliance), which forwards or rejects/drops packets on a network.
    • Typically firewalls are used to define zone borders. Firewalls generally have rules restricting which ports are open.

Your network uses TCP/IP as the only network protocol. Devices on the network are configured to use IP address from the private 10.0.0.0 range. All the client computers on the network runs Windows 2000 Professional. The network includes Windows 2000 Server computers and UNIX servers. User's print jobs are sent to shared printers on a Windows 2000 Server computer named PrintServ that directs the print jobs to print devices attached directly to the network. You have a high-capacity print device that is attached to one of the UNIX servers. The UNIX computer uses the LPR printing protocol, and it's IP address is 10.1.1.99. The name of the printer queue is GIANT. You want users to be able to connect to this printer from their computers. What should you do?
