There are five key principles, essential for safe electronic
transactions:
- Confidentiality- keeping information
private
- Integrity - ensuring information has
not been tampered with
- Authentication - confirming the identity
of the individual who undertook the transaction
- Non-repudiation - the individual who
undertook the transaction cannot subsequently deny it
- Availability - ensuring information
is available when required
Information Assurance is about meeting these requirements. |
