Two types of access - Physical and Logical.
- Physical Access. The process of obtaining use of a computer system, - for example by sitting down at a keyboard, - or of being able to enter specific area(s) of the organisation where the main computer systems are located.
- Logical Access. The process of being able to enter, modify, delete, or inspect, records and data held on a computer system by means of providing an ID and password (if required). The view that restricting physical access relieves the need for logical access restrictions is misleading. Any organisation with communications links to the outside world has a security risk of logical access. Hackers do not, generally, visit the sites they are hacking in person.- they do it from a distance!
