Entering a power-on password At the Enter Password prompt, type your password, and then press enter. After 3 unsuccessful attempts to enter the password, you must restart the computer and try again. Using Internet security software When you use your computer to access email, a network, or the Internet, you potentially expose your computer to computer viruses, spyware, and other online threats. To help protect your computer, Internet security software that includes antivirus and firewall features are included on your computer. To provide ongoing protection against newly discovered viruses and other security risks, security software must be kept up to date. Using antivirus software Computer viruses can disable programs, utilities, or the operating system, or cause them to function abnormally. Antivirus software can detect most viruses, destroy them, and in most cases, repair any damage they have caused. Antivirus software can be downloaded from the Novell Customer Center (NCC). See Updating programs and drivers on page 57 Using firewall software Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be a software program you install on your computer and/or network, 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 e-mail 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. 1. To view or modify the firewall settings, select Computer > YaST. NOTE: When accessing YaST, you are prompted for the root password. 2. In the left pane, click Security and Users, and then click Firewall in the right pane. NOTE: When modifying firewall settings, you are prompted for the root password.

Using firewall software
Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be a
software program you install on your computer and/or network, 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 e-mail 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.
