Digital security is an all-encompassing term which includes the tools you can use to secure your identity, assets and technology in the online and mobile world. These tools you can use to protect your identity include anti-virus software, web services, biometrics and secure personal devices you carry with you everyday.
There are ultimately three pillars when it comes to data security:
Integrity: we must be sure that the data we’re trying to secure has not been modified or corrupted. We must also be sure of the source: are we certain it originates from the right person, and is that person who they claim to be?
Confidentiality: We must keep things private or limit the data’s availability to certain, pre-specified people or organizations.
Availability: We need it to work so that interactions and transactions etc. can run conveniently all the time
