- 1Network securityComputer networks have many benefits but they also create security risks. By connecting computers it is possible to share personal data easily. However, it makes computers more vulnerable to interference from other people.
- 2Anti-virus softwareThere are a number of malicious software (‘malware’) programs that can cause damage to computers. These include viruses, worms, zombies, Trojan horses (Trojans) and Spybots.
- 3FirewallsA firewall is software that will block unexpected connections coming in to the network. Most operating systems include a firewall.
- 4Secure passwordsWhen more than one person uses a network it is important to have user IDs and passwords. Only someone with a login and password can access that network. It also helps the network manager trace unusual activity to a specific user.
- 5Access levelsIn a large company or school, many people will be using computers on the same network. A network manager will normally control the level of access people have to the network. General users will not have the ability to download any software they want or to make changes to any part of the system, as that could affect other users.
- 6ArchivingNetworks often have to store a lot of data. A good archiving strategy takes old, non-essential data and puts it somewhere safe. An archiving policy will help decide when to move data, where it should be kept, and how to get it back if needed.
