If you are very good at restricting all information, that state or corporations will have problems monitoring you. However, you are also likely to become more isolated and secretive in the process. Information security is primarily based on protecting equipment with security procedures and barriers. Securing the information on your computer will help your overall security. If you have a portable computer you are presented with a whole new problem because you move that system outside of your ordinary systems of security and access barriers. Therefore special care should be taken with portable computers:
The system should be secured with a BIOS password to prevent booting;
Use encryption of the hard disk, where possible, to prevent access to the contents of the hard disk if it is removed from the machine;
Ensure that your portable computer has different passwords than those used on your static equipment.
Securing your information is fairly easy. But the main issue you will have to deal with when considering personal surveillance is how to carry out meetings, and networking with people, when you need to discuss sensitive issues.
