No one can deny the ubiquity of the Internet in this day and age. Even grade schoolers can now access the Internet in the comfort of their own homes. But parents have a perennial worry that their child might be viewing inappropriate sites or might be talking to people they should not be talking to online. For starters, parents should make sure that all computers in the house are located in a common area, like the living room. On the technical side, there are resources out there that can help restrict sites visited by your child.

Secretary of Homeland Security, Michael Chertoff, said that the U.S. government's cybersecurity people are trying to come up with an early warning system to detect computer attacks on sensitive infrastructure. Some experts, though, think that this idea is not quite feasible. Present technologies are only able to detect a hack after the fact. Chertoff remains persistent, though not clear on the details as they are considered classified information. Chertoff's department also aims to reduce Internet access to government agencies that would hopefully lessen the chances of getting hacked. The project would require experts from the private sector said Chertoff, but he did not yet say exactly how many they will be needing.

Almost everything now is done through the Internet - from bank transactions to keeping in touch with family and friends - as long as you have an account with a site, you are required to come up with a password. To keep your password safe and secure, be sure to keep in mind these following tips:

1. Avoid using dictionary-accepted words, names of persons, places or things and foreign-language words.

2. Avoid incorporating any personal information in your password (i.e. employee number or birthday).

3. Make sure your password is made up of at least six characters.

4. It is recommended to combine uppercase and lowercase letters, numbers and special characters in your password.

5. Create a unique password for each account that you have.

6. Do not let a soul know what your password is.
