What steps could you take to help secure a computer against internet attacks for a small LAN with 12 computers connected via a hub?
- The first step would be to install and maintain a good anti-virus, anti-spyware, and anti-adware software on your computer.
- You should also enable the built-in firewall that probably comes with the operating system installed on each computer.
- If the hub is a "dumb" hub, you probably can't do much with that, but if it is a "smart" hub, you can also configure it to provide some firewalling and traffic filtering capabilities. Refer to the manual for the hub to find out what, if any capabilities it might have.
- If possible, install a firewall and/or proxy server between the LAN and the internet to protect all the computers on the LAN. Turn off the computers when they are not in use.
- Use usernames and passwords on all the computers
- If the operating system has the capability to have accounts with different permission levels - like "administrator" and "limited user" create limited accounts on the computers and always operate the computers under a limited account except when absolutely necessary to perform functions that require administrator level access - and then log off the administrator account as soon as you are done
- Enable pop-up blocking on the browser(s)
- Set the privacy/security settings on the browser(s) to the most restrictive level that is consistent with operational needs
- Create an "acceptable use policy" document that spells out what is and is not acceptable use of the computer resources on the LAN and consequences of misuse, then have everyone who is authorized to use the computers on the LAN read the policy and sign an agreement stating that they have read the policy and agree to abide by it.
- Train all users in best practices for computer security in personal computer use
- Teach all users to recognize and avoid phishing and other social engineering attacks
- Require users to change their passwords at least every 6 months - every 3 months or more often if you want to add to relative security
- Keep all system patches up-to-date including both operating system patches and application patches
- Only download patches from trusted sites - for example - only get Microsoft patches from the Microsoft site, not a 3rd party site.

What is Usefulness of firewall?
Each computer that is connected to the Internet (and, more generally, to any computer network) is likely to become a victim of a computer attack by a hacker. The methodology generally used by hackers consists in scanning the network (by randomly sending out data packets) in search of a connected computer. Once a computer is found, the hacker searches for a security weakness in order to exploit it and access the data on the machine. For several reasons, this threat is even greater when the machine is permanently connected to the Internet: * The targeted machine is likely to be connected but not monitored * The targeted machine is generally connected with a greater bandwidth * The targeted machine does not change or rarely changes IP addresses Therefore it is necessary for both company networks and Internet users with cable or ADSL connections to protect themselves from network intrusions by installing a protection device. A firewall is a system that protects a computer or a computer network against intrusions coming from a third-party network (generally the Internet). A firewall is a system that filters data packets that are exchanged over the network. Therefore, it is a filtering gateway that comprises at least the following network interfaces: * an interface for the network being protected (internal network) * an interface for the external network the site to use http://en.kioskea.net/contents/protect/firewall.php3
