Always minimize the access other people have to your information. It’s simple to identify people who can gain physical access to your computer, but it is much more difficult to identify people who could gain remote access to your computer. Make it difficult for them. Lock your computer when you are away from it. Disconnect your computer from the Internet when you aren’t using it. Evaluate your security settings. Protect your computer against power surges and brief outages. And always back up all of your data.
