Using firewall software Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be a software program that you install on your computer, network, or both, or it can be a solution made up of both hardware and software. There are two types of firewalls to consider: ● Host-based firewalls-Software that protects only the computer it is installed on. ● Network-based firewalls-Installed between your DSL or cable modem and your home network to protect all the computers on the network. When a firewall is installed on a system, all data sent to and from the system is monitored and compared with a set of user-defined security criteria. Any data that does not meet those criteria is blocked. Your computer or networking equipment may already have a firewall installed. If not, firewall software solutions are available. NOTE: Under some circumstances a firewall can block access to internet games, interfere with printer or file sharing on a network, or block authorized email attachments. To temporarily resolve the problem, disable the firewall, perform the task that you want to perform, and then reenable the firewall. To permanently resolve the problem, reconfigure the firewall. Installing software updates HP, Windows, and third-party software installed on your computer should be regularly updated to correct security problems and improve software performance. To view or change the settings: IMPORTANT: Microsoft sends out alerts regarding Windows updates, which may include security updates. To protect the computer from security breaches and computer viruses, install all updates from Microsoft as soon as you receive an alert. You can install these updates automatically. 1. Select the Start button, select Settings, and then select Update & Security. 2. Select Windows Update, and then follow the on-screen instructions. 3. To schedule a time for installing updates, select Advanced Options, and then follow the on-screen instructions.
