what exactly r u asking?  The first site is the best place to start, then try the second one for just plain old info..  If your really want to know more take a course from Comptia in Security +.  That will teach you a lot about those issues.

If you want to research PC security, the best places to read about that are, PC Magazine, http://www.pcmag.com/ , PC World, http://www.pcworld.com/ , Cnet, http://www.cnet.com/ and last but not least ZDnet, http://www.zdnet.com/ just do searches on their site for "pc security" and I'm sure you will find a number of things that you are looking for.

The risk - Identity theft, credit card theft, viruses, etc.\n\nI don't know a lot, but I do know you should get a really really good firewall.\n\nBut taking a chance to use any network that's unsecured is just that, a chance. So don't put anything really personal out there on your computer. And if you use it, don't go on a shopping spree while on that connection. Your information could be open to anyone.

data integrity  \nRefers to the validity of data. Data integrity can be compromised in a number of ways: \nHuman errors when data is entered \nErrors that occur when data is transmitted from one computer to another \nSoftware bugs or viruses \nHardware malfunctions, such as disk crashes \nNatural disasters, such as fires and floods \n\nThere are many ways to minimize these threats to data integrity. These include: \n\nBacking up data regularly \nControlling access to data via security mechanisms \nDesigning user interfaces that prevent the input of invalid data \nUsing error detection and correction software when transmitting data  \n--x--\ndata security     \n In the computer industry, refers to techniques for ensuring that data stored in a computer cannot be read or compromised by any individuals without authorization. Most security measures involve data encryption and passwords. Data encryption is the translation of data into a form that is unintelligible without a deciphering mechanism. A password is a secret word or phrase that gives a user access to a particular program or system.
