The opening of the Internet has significantly transformed global communications, allowing all the world to exchange information. At the same time, this "openness" has created a huge problem. Anyone has the ability to access the network, but not everyone has good intentions. Implement some malicious activity by distributing malicious software on your computer or other programs, while others simply try to go into people's computers as entertainment or sports. And then there are those who only have criminal intent.
To avoid becoming victims of these actions is good to examine the level of security with which they protect their data. Here are some recommendations:
- Install a firewall on each computer

Although the hardware firewall can be set to block some or all packets passing through the port 500 for example, can not know which application has started the TCP / IP communication on your system. A software firewall asking if you let pass or not, some communications on a certain port.

Using a computer connected to the Internet without an antivirus it is irresponsible, given the high number of viruses can attack in many ways operating systems. Even if you think you know how to avoid viruses, it might be the victim of a virus that uses a technique not common. If your computer is infected, there is likely to infect other computers on the network your home or office, including those that are in your address book e-mail.
