Unit 3 - Security LO1 1.2

1. Unauthorised access

   • This focuses espcially on hacking, as hackers gain access to other computer systems without permission of the owner, therefore it is an unauthorised access.
   • Another example of unauthorised access is escalation of privileges, which means, for example, that teachers give themselves a higher level of access as they actually should have.

2. Modification of data

   • Data can be changed by those who have authority to do so. The data will still be useful.
   • An example of this are teachers which change GCSE grades of students.

3. Inaccessible data

   • This refers to denying access to certain data from specific people.
   • For example, students shouldn't have access to the teachers' drive.

4. Destruction

   • This means to delete data which is not needed anymore, such as data of customers which didn't shop for longer than two years.
   • Also this could reflect on viruses which delete data that is still needed

5. Theft

   • This means stealing data, property or money using hacking software.
   • An example of this could be a Trojan virus.
