Not necessarily - There are many times integrity and access are far more important than confidentiality - control systems for example. For sensor streams, availability may even be more important than integrity. There are already algorithms in place in control systems to deal with bad or weird data from those sensors because sensors go funky all the time. having the tampered data is still a form of information that the sensor is still there, a surprisingly useful bit of data itself. There is a lot of research in control system security about balancing extremely high availability requirements against bad data and commands coming in -- trying to answer the question "how do we run compromised" because sometimes you have to, at least for a limited time, to prevent bigger systemic damage.
