Technology is becoming more effective at early ransomware detection. Solutions can often automatically shut down attacks and minimize the damage. It is reasonable to conclude, however, that there is no truly impenetrable ransomware defense. The more complete answer lies in recovery.
Maintaining pristine datasets that are more readily restored, minimizing loss while preserving data integrity, is arguably as important as prevention in a cybersecure posture. This means making data immune from damage or alteration, and in some cases tracking access and copy patterns, so recovery from attacks is possible without paying ransoms or exposing sensitive information in the first place.
