Information Assurance

Information Assurance (IA) is the process of keeping information and data secure. It encompasses a large area and has many applications but in essence, it involves ensuring the 3 leading principles, CIA.

C I A definition

Confidentiality

This is the act of making information available only to those that are authorised. If done properly, only the intended recipient should receive and/or be able to read/use the information. No unauthorised individual should be able to see the data. A common implementation for this is peer-2-peer encryption.

Integrity
This refers to the continuous act of ensuring that data is valid, accurate and consistent. It involves making sure that data is not altered unless absolutely necessary, by an authorised individual or so that it is accurate (e.g. changing record of a user’s address if they move house). If properly maintained, the data can be considered trustworthy. The range of solutions for this depend on how deeply you want to account for, the basic solution is correctly configured file permissions and access controls whereas more in-depth strategies such as checksums can verify integrity even in the event of obscure electrical interference.

Availability
If data or a service has availability, in the context of information assurance, that means it is usable. This may sound simple but involves the assurance that under any reasonably expectable circumstance, a user is still able to access the data or service that they are used to accessing. You need to be able to account for any hardware or software failures with sufficient backup and redundancies in place, resource bottlenecks caused by a surge of traffic whether natural or intentional (e.g. DDOS attack) all the way down the line to the worst case, disaster recovery. There are potential solutions to account for all of these cases but understanding them and being able to implement them are tricky.
