Just saw that there's tag for safety, with no usage guidance, and questions mostly about how "safe" something is. Seems like it should be a synonym of security. Or nuked altogether.
There are commands that are unsafe (variations on
rm come to mind) but not exactly insecure (they don't expose the system to an attacker). So perhaps not really a synonym. However, the tag is vague and could be used for all kinds of randomness. I can't think of a situation when it would help to define the subject of a question. I think we should just get rid of it.
in computer science :
according to this paper Basic Concepts and Taxonomy of Dependable and Secure Computing safety is a property of dependability and security is a composite of the attributes of confidentiality, integrity, and availability.
this picture shows the relationship of dependability and security :
note : The picture should not be interpreted as indicating that, for example, security developers have no interest in maintainability, or that there has been no research at all in the dependability field related to confidentiality rather it indicates where the main balance of interest and activity lies in each case.
by knowing the definition of these attributes the difference will be more clear :
- availability: readiness for correct service.
- reliability: continuity of correct service.
- safety: absence of catastrophic consequences on the user(s) and the environment.
- integrity: absence of improper system alterations.
- maintainability: ability to undergo modifications and repairs.
according to these definition and difference between security and safety, you may need both security and safety.
3Your argument might make sense if we created tags for everything that meant slightly different things. We don't. Are any of the questions tagged safety not about security?– muruMar 28, 2017 at 11:20
Safety is for the user standpoint and Security is for a program standpoint
rm -rf /was bricking some computers with an UEFI firmware: phoronix.com/… If we want to extend the concept of safety to hardware, other than people, some questions might be on topic. Probably not too many to deserve a tag, though. :)
