What is meant by "software systems integrity" when defining non-functional requirements? 

I have found a lot of definitions for the integrity as a non-functional requirements for software systems, some indicates for example that for the integrity requirements only the system administrators should be able to add new item into the system, other indicates that users should be authenticated before accessing the system
So are these examples of integrity or they are example of security or privacy requirements

This is a term that has multiple definitions.

Some examples (thyere are more)

Integrity

Security context = Impervious to outsider attach - eg hackers trying to break into your network

Rights context = only the right users can make certain changes - eg Only system admin can add new users

Internal consistency = All the internal logic (and data) makes sense when operating together - eg - all units of distance are metric

Contextual consistency = the workings of the system operate in a logical way in the context of it's surrends - eg system integraton, or even the rules in the system align with the rules of the organsaition.

 

Interesting question - what led you to post this?

John,

Integrity - see http://technet.microsoft.com/en-us/library/cc700839.aspx

A few of the things to watchout for are 1) you want the right people to have access to your system and 2) you want your data (images) to be fiddle-proof so that people cannot corrupt/hack your data. Do a search on Authentication and Integrity!

warm regards,

K

I’ve heard “The End is Near!” for Business Analysts for almost 20 years.  Waterfall project management, with its need for formal requirements, is dead…a dinosaur…so 1990’s.  To be honest, that’s mostly true.  With the publishing of the Agile Manifesto in 2001 there was no need for a 2-inch-...
