First it was the Hollywood Presbyterian Medical Center in LA. Their data got encrypted by malware and held hostage to a $17,000 ransom.
Now it is Lukas Hospital in Germany.
Many people focus their security efforts on the “Confidentiality” aspect of Security. I don’t know if either the LA or German hospital failed to protect the Confidentiality, but the attack they fell victim to could easily have happened to a database that was perfectly protected against Confidentiality risks. The database might have been encrypted by the database software with very good management of that encryption key. This protection would not have prevented the database from being Encrypted AGAIN. Yes, an encrypted system can be encrypted again.
It is possible that the databases were fully readable in the form that the malware encrypted. I am not trying to declare that they were. My point is that unless you address all aspects of the Security risk domain, then you have left unmitigated risk.
Clearly if the data is not backed up, then there is also failures to protect against Integrity risks.
