Defense Strategies Have Holes
To defend against ransomware, you can either prevent the attack or contain its impact. Attack prevention often involves training programs for users, advising them to avoid “phishing” attacks such as emails whose senders are posing as trusted sources. Another prevention strategy monitors emails and network activity to detect unusual behavior.
Finally, you can simply isolate critical systems behind additional layers of firewalls and password challenges to limit access. In the long run, these preventive solutions ultimately fail as attack technologies evolve.
